WOW! ... Thanks for your reply! I was really breaking my head.

I have not cross-imported 3 to 4 or vice-versa, but rather, from the 
very start, working on a RD4 machine from scratch for the testing... But 
after patient work on setting marks on 3/4 of my tracks on RD4 
RDlibrary, I'm starting to notice that something is wrong.


Have you opened an issue on the Github repo for this? (I guess that this 
may probably be considered a quite ugly bug!)


Thanks, regards.

This leads to very similar results as you're describing. There's 
definitely a bug of some sort in the way RD4 deals with fade markers.

a way to prevent the cut to be faded down on segue (for instance
if the cut audio itself fades down nicely) or as a way to take
control of the actual fading down by means of a fade-down marker.

Anyways, the fact is that I forgot to mention that I'm beta
testing RD4 :-P ... so anything could happen!

fade up mark for a whole 8 beat bar, and I'm failing to perceive
nice progressive fade ups, but rather sharp/sudden playback
starts, resulting in mediocre transitions/segues ... Will have to
invest time to be sure.

Anyhow... thank you very much!

Re: [RDD] Rivendell v3.x on Debianish distros [WAS: Rivendell v3.6.4]

2022-02-28 Thread Alejandro olivan Alvarez

Hi Fred!

I think I failed explaining my point correctly... What I meant was to,
essentially, add a /debian folder (I know that isn't that simple... :-)
in Rivendell 3.X code, without any functional code modification at all
(therefore, only useable on 'still qt4' releases)

Rivendell 3.X code runs perfectly stable, and full featured, on Debian
Buster/10 (currently old-stable release, and I'm sure so it does in
Ubuntu 18 LTS and other derivatives). I remember I managed to package it
(although very very rudimentary) with just a couple of patches to solve
'make' issues (mostly math lib in header files and a few things like
that), and some other minor tweaks ... but the source-code itself, as it
is, once compiled, produces rock-solid full-featured and compatible
binaries with Debian 10.

Regarding SQL, I recall that the only problem found was that MariaDB had
to be reconfigured to run into non-strict mode (or the other-way around,
not sure) just to prevent rdcatch crashing, but other that that, the
compiled binaries worked like a charm, out-of-the-box, on Debian 10
MariaDB (And I bet same is on Ubuntu of the time and earlier).

The main problem I see is that, at the end of the day, even if barely no
code modification is needed, the time and effort to add/enable
debianistic packaging for 3.X would be expended just to target
OS/systems that are already superseded by newer ones (although probably
much more modern than CentOS7, and maintained beyond 2024)... the move
would only pay off if the time/effort would be very very little...
(maybe merging /debian folder of already existing packaging repos?)

Sure, I agree there's no point on targeting 3.X to current Debian
Systems (Bullseye/11, Ubuntu 20, etc...) the sole qt4 to qt5 task
performed in 4.x is gigantic ... 4.X is the future on qt5-only systems :-)

Best regards.

Unfortunately, the packaging challenge is only part of the problem
with Rivendell v3.x. on current Debian/Ubuntu. Much larger than that
are the issues with RDBMS (MySQL/MariaDB) compatibility. A big part of
doing v4.x was checking (and in many cases, remediating) every SQL
statement in the codebase to ensure compatibility with current
MySQL/MariaDB versions. There are literally hundreds of such
statements in Rivendell.

HI!

Nice one to have.

I keep also a public repo for Rivendell4.X that includes both, releases, 
and nightly snapshots, for Buster, Bullseye and Bookworm, to ease 
testing (I have a 24/7 VM running Bullseye with Rivendell 4.X 
bleeding-edge nightly snapshots, and is totally stable, no crash... 
although some things are broken and do not work at all).

I've refactored the packaging to be as close as possible to the 
packaging scheme of v4.0.0beta3, but using genuine debhelper package 
splitting instead of the very manual file distribution among the 
different package build directories as it is currently done in 
v4.0.0beta3. I borrowed some compile tricks from the "rules" Makefile 
of v4.0.0beta3 in order to improve my own build process so that the 
manpages embedded in the packages I provide are working well now ! 
Thanks a lot ;)


Don't hesitate to send me feedback so that I can make some adjustments 
before sending a pull request for the debian packaging files, which 
should ease package maintainability

Re: [RDD] Reference OS

2022-02-25 Thread Alejandro olivan Alvarez


Hi.

Being a Debian and radio enthusiast, Rivendell definitely caught my 
attention when it went 'debianized' in the development branches, of what 
will be in the future the next big release Rivendell4. However, the 
debian-based reference OS was (or is, AFAIK) Ubuntu-Studio, NOT Debian 
itself.


I packaged Rivendell 3 (as other did also) for Debian Buster, in order 
to learn and test it, but unlike Rivendell 4, it's sources are not meant 
to be debian-packaged out of the box, and the resulting packaging and OS 
integration (at least with my packaging skills) was somehow ugly ... 
However, the Rivendell 3 on Buster was ROCK SOLID and operated perfectly.


Rivendell 4 OTOH being debian-friendly on its sources, makes incredibly 
easy to maintain packaging-wise, so there're already Debian repos around 
(I myself keep one to help/ease install and test 4.X)... However, in my 
experience, there're some important problems with 4.X and Debian, so 
Ubuntu-Studio is IMHO the sure-bet for Debian-based distro and 4.X at 
this time.


AFAIK CentOS support will be maintained (obviously) so, CentOS 8 (and i 
bet upcoming CentOS verions and/or project forks) is for sure, one, if 
not the best option.


Best regards.

Re: [RDD] Auto restart after power failure.

2022-02-22 Thread Alejandro olivan Alvarez


Regarding your first question (fully automated auto-start of Rivendell)

It is doable for sure, however, the actual details on how to achieve 
that, very much depends and/or conditions on what pieces make up your 
'Linux' system (I assume that your hardware, has in BIOS the appropriate 
setting to power-on after a power failure)


As a general idea, you need to setup your session manager (which may 
depend on what Desktop-Environment have you installed.. GDM, XDM, KDM, 
Slim, etc...) to auto-login your user upon system boot.


Once you achieve that, you have to setup that, upon login, your user 
session automatically launches whatever software you need (and again, 
depending on the environment, there are different ways to do that).


As I think we can assume that you want RDAirplay going to air, apart of 
having Rivendell daemons up and running, you need, by one side, to 
either setup RDAirplay to automatically load on the LogMachines the last 
logs that was loaded (a feature you can setup in RDConfig) or to script 
the loading of the log you want using a MACRO. And then, make it to 
play This links to your second question.



Commands to air in proper time:

There are commands to do quite a lot of actions related to the thing you 
want: you can launch a command that makes RDAirplay to play a cart, to 
play the next cart in the log, or to 'push' one of the buttons of the 
Main log, just to mention some...Rivendell Macro Language makes the 
whole thing incredibly flexible!


However, consider that, if properly taylored, a log, on its own, can go 
to air 'by itself' if it has scheduled a cart to be aired on hard time 
(I recommend you to look at the Start time types, transition types and, 
overall, the behaviour of the logs on RDAirplay ) with a stop transition.


Moreover, there's a wonderful module (RDCatch... I miss it very much in 
Debian beta4) that is all about executing tasks (including for sure 
executing a command) on the wallclock, so you don't need to have a 
wallclock log dedicated to schedule hard time tasks. So, in RDCatch, if 
you create a Macro cart that loads a certain log on a RDAirPlay log 
machine, and starts its playout, and you schedule that cart on 
RDCatch... then, no matter what, when the time comes, the cart will be 
executed)



Hope I gave you some clues on where to focus on.

Best regards.

Re: [RDD] Here's one I haven't seen before

2022-02-09 Thread Alejandro olivan Alvarez

Hi... not actually Rivendell related, but certanly so in general-purpose 
Linux desktops (mine, more specifically :-P, but quite long time ago... 
I use Debian testing in my computers, so I'm not surprised experienced 
issues from time to time), and its just as you describe.


In my experience, what leads to that behaviour were related to some kind 
of filesystem access/handling issue.


Either the filemanager application instance that is handling the Desktop 
itself crashed (Desktop being often yet another Folder at user home 
folder) misbehaved


Or some nasty GNOME Virtual Filesystem happened that lead to the problem 
above to happen.


Chances of those problems happening greatly increased if/while stressing 
the system with mounting remote filesystems, and/or mounting multiple 
remobable storage devices, and/or having many file manager windows 
opened while moving bunch of files between them.


Sure, your problem could be totally different...  this is just what I've 
experienced.


Best regards.

You can move the mouse cursor, but can't actually click on anything. 
rdairplay continues merrily along playing audio, and if you ssh into 
the machine, you can enter commands and they'll work normally. But the 
person in the studio sitting in front of the machine -- or anyone 
logged in via VNC -- can't do anything but watch. If I reboot the 
machine, the problem will go away.


Of the two machines where I observed the problem, one runs Rivendell 
version 2.19.3; the other is running 3.4.0; both are running CentOS 7.


Has anyone else encountered this problem?

[RDD] EX RML Macro Usage issues.

2022-02-08 Thread Alejandro olivan Alvarez


Hi again list!

Again... having some issues understanding how to correctly use the 
Macros, this time the EXecute Cart Macro.


I have created a set of three macro carts, two of them switch a pair of 
jackd endpoints to FFMPEG (combining JD and JC), and a third that clears 
all connections on FFMPEG (all JD). So far so good. Macros do work as 
expected when pushing the Run Macro button on RDLibrary, and I expect 
them to work if I use them within a log or in RDCatch.


However, being a fan of RDSoftKeys, I wanted to asign those macros a 
soft button and, therefore, I need to instruct RDSoftKeys to Execute 
those carts... so, I found the EX macro to be just what I needed, but it 
does not work :-(


In order to get rid of eventual mistakes on RDsoftkeys, I then tried to 
run the cart through an EX rmlsend on the console (as I usually do for 
testing) and it didn't work either...so I'm missing something on the EX 
Macro... could you point me how to use it (bellow are details of my tests)?



Cart 050009 exists in RDLibrary, runs and works! (this is syslog output):

Feb  8 13:38:59 debian ripcd: received rml: "JD ffmpeg:input_1 
rivendell_0:playout_2L!" from 192.168.112.11

However as I run this in console:

rmlsend --to-host=127.0.0.1 EX\ 050009!

I just get this on syslog, but absolutely nothing happens:

Feb  8 13:34:35 debian ripcd: received rml: "EX 050009!" from 
:::127.0.0.1



What am I missing? I have tried with and without leading 0, also using 
quotes... I'm sure I'm missing something very basic!

Greetings Alejandro,

I have used the JC and JD macros with success in the past. Maybe you have tried this, but 
I recommend changing the order of the "ports" in your JC and JD invocations. In 
other words, specify the ffmpeg ports first and the rivendell ports second in the rmlsend 
command line.

Hope this helps!

However, I'm failing completely at the very most fundamental action, so

I'm feeling that maybe I've completely misunderstood the point behind

JC, JD and JZ Macros.

So... Given that the following CLI command do work (nothing fancy):

jack_connect rivendell_0:playout_1L ffmpeg:input_1

Now, I assume I can do the same with JC:

rmlsend --to-host=127.0.0.1 JC\ "rivendell_0:playout_1L"\ "ffmpeg:input_1"!

rmlsend --to-host=127.0.0.1 JC\ rivendell_0:playout_1L\ ffmpeg:input_1!

However, although syslog logs those RML being received and

processed...nothing actually happens.

So, I'm assuming I'm either making a syntax mistake or JC macro is not

intended to be used like that... Could someone share his/her experiences

with that? Or what does JC/JD/JZ do?

As a side note, I also though on using RN to pass jack_connect command,

but It didn't worked either (I always though on RN as a way to execute

scripts, not commands with arguments)

being able to integrate that as Events either in RDCatch or in a 
LogMachine makes lot of sense to me.


However, I'm failing completely at the very most fundamental action, so 
I'm feeling that maybe I've completely misunderstood the point behind 
JC, JD and JZ Macros.



So... Given that the following CLI command do work (nothing fancy):

jack_connect rivendell_0:playout_1L ffmpeg:input_1


Now, I assume I can do the same with JC:

rmlsend --to-host=127.0.0.1 JC\ "rivendell_0:playout_1L"\ "ffmpeg:input_1"!

rmlsend --to-host=127.0.0.1 JC\ rivendell_0:playout_1L\ ffmpeg:input_1!

However, although syslog logs those RML being received and 
processed...nothing actually happens.


So, I'm assuming I'm either making a syntax mistake or JC macro is not 
intended to be used like that... Could someone share his/her experiences 
with that? Or what does JC/JD/JZ do?



As a side note, I also though on using RN to pass jack_connect command, 
but It didn't worked either (I always though on RN as a way to execute 
scripts, not commands with arguments)



Thanks.

Re: [RDD] Ransonware attack

2021-12-15 Thread Alejandro olivan Alvarez

I would like to share some other thoughs here.

If you look at debian security repo packages notes, and you look for
samba, you will find that, for the last vulnerability, found this 2021,
only the packaged sources for Debian Stable, testing and Sid have being
patched with the fix uploaded in samba.org. Older packaged versions,
including buster (which was stable until well within 2021) have not
(probably they can't due to aging code) been patched and are marked as
'vulnerable'.

Samba/Windows/SMB/etc has its vulnerabilities, like many other software,
but the difference here is that, the attack surface is far greater,
since, out of the dark, Windows computers become potential backdoors for
our Linux ecosystem.

Being a Linux-only user, I would add that, IMHO (and risking to be
polemic) nothing is more secure regarding security fixes/updates on the
SMB protocol than MS Itself (Windows server environment, with AD)... MS
will be the first to detect AND DEPLOY any security fix for MS machines
via Windows Updates. A Linux machine, on the other hand, can live
happily with older/vulnerable samba packages for ages.

If I had to think of an ideal mixed Win-Linux environment for ease
Dropbox upload/ingestion, my recommendation would be to have a Rivendell
machines connecting as clients to a Windows Server, under AD (which is
possible at OS level, but I recall maybe it is not for
rdimport/export/etc ), and mount the remote share to read/ingest
dropboxes, while the rest of the Win machines mounting the same share to
do the uploads. This way, all the Win files would stay contained within
the windows environment, subject to AD handshake all the time and
possibly under antivirus scrutiny... as we say here 'Juntos, pero no
revueltos' (toghether, but not mixed)

Cheers.

Fred, is building some more security into the system something that

As far as the installers are concerned, there are two main goals that
we try to achieve:

1) Provide a “good experience”, in particular, a working, functional
setup “out of the box” so that new users can see what Rivendell is and
is capable of.

2) Install a good foundation, one that is reasonably secure, easy to
update and to maintain according to industry best practices.

To an extent, these two goals tend to work against each other,
especially with regard to the ’security’ metric. The first questions
any new Rivendell user asks after getting the installer to work and
playing the Test Tone cart typically are:

How do I load audio into this thing?

How do I get schedules (“logs”) into this thing?

How do I get as-played data out of this thing?

Or, in general: how do I transfer data in/out?

Given that our putative new user typically has limited (if any) Linux
knowledge and indeed, limited or no formal IT experience at all, as
well as that, in the overwhelming majority of cases, the data that
these new users want to use resides on one or more Windows systems,
our traditional approach for facilitating data transfer has been to
provision, by default, a set of CIFS shares configured to allow
‘guest’ access. That makes them easy to find and access by the typical
moderately-knowledgeable Windows user. Unfortunately, it also makes
them easy to find and access by the Black Hats if (when?) they manage
to get access to the LAN to which the system is connected. Yes, the
permissions on those shares can be tightened after installation so as
to allow only users with the actual need for access to do so, but how
many new users know how to do that? How many know that it’s even
*necessary* to do that?

This is the fundamental tension that we have to deal with when setting
up default installation environments. Sure, we could refrain from
installing Samba and wind up with a more ‘secure’ setup, but only at
the price of the user having to configure the requisite access (NFS?
Remote mount a CIFS share on a Windows box? Install Samba?) All
doable, but in no case immediately obvious for the average new user.
For that user, doing any of those things is going to amount to getting
thrown into the deep end of a very cold pool.

I guess, at the least, we could call out these sorts of issues in the
‘Final Steps’ section of the instructions, along with pointers for
various resources.

Cheers!

2021-12-15 Thread Alejandro olivan Alvarez


Hi.

I remember that issue in my early attempts to build debian Buster (then 
stable release) packages for rivendell 3.x


Apparently, CentOS 7 (I guess that came from previous) shipped 
versions/defaults for the building/linker environment allowed for math 
libraries not needed to be declared in tha header files, while in Buster 
(and I asume that's the trend for newer versions) that wasn't the case.


The way I solved that was by quilt patching the sources adding the math 
library on the troublesome files (don't recall on it).


As Rivendell is evolving under the qt5 branches towards more recent 
systems, I remember at some point Fred wiped out all those errors 
rendering all my tricks and hacks unnecessary... so, you may search in 
the commits to for math/pow10 building issues to get how to patch the code.


I think I still keep my notes on it...I will search for them just in case.

Hi,

Some interesting ideas here.  One thing that I would say is that we 
are not all networking experts.


This December my last CISCO certification ends, and I'm not going to 
re-cert... and for a good reason: On the 10 years I've been working in 
my current job, only in one case, the entity, budget and complexity of 
the customer (A public/national radio network) networking infrastructure 
made applicable my CCNA/CCNP knowledge. In all other cases, I rarely 
find anything beyond a simple, flat, L2 broadcast domain (i.e a cheap 
un-managed or very simple managed switch with no data VLANs)... But 
here's the thing:


Once you gained access to a Linux (or windows, I guess, but I'm Linux 
user) host, it is VERY EASY to exploit a Layer 2 (VLANs) deployment by 
several techniques (I'm thinking on just a simple python script to scan 
for VLAN hopping exploit, to say a kiddies one) unless the network 
devices do feature AND have configured/enabled several security features 
(ARP spoofing, DHCP snooping, port security policies, etc, etc). That 
requires knowledge and usage of more expensive gear. But the thing is 
that, preventing of an attacker to gain access of an internal host in 
the first place is, by far, the single, most important point to put the 
focus on.



  I have to admit that some of the stuff you are talking about goes 
over my head.  I've not had cause to look at AD in any scope.  Would 
it be possible to point us in the direction of a useful (in this 
context) Samba4 AD beginners primer to get started?


I like the onion/layered principle for a security approach, and, since 
network deployments can largely vary from organization and organization 
(and is something kinda 'external' to the software level) I like the 
idea of strengthening or provide guidelines for securing Rivendell 
deployments at the immediate practical use-case, software level.


Regarding SAMBA, AD and Rivendell, I think the very early measure would 
be to focus on securing SAMBA on its own (Rivendell/AD integration is 
something more of a Quality of Life than of security, and thus, of 
secondary order) on deployments where Dropboxes have to co-exist with 
Windows machines... The problem is that there are several 
use-cases/scenarios and the approach may differ from case to case (who's 
sharing? a Linux box? a win box? a NAS? are all Dropboxes in a 
centralized share? do Machines share on their own? is there an AD in 
place?...)


Best regards.



Thanks

Since inter-operation with Windows machines is a very probable

Dropboxes) I'm wondering whether a good practice for a
professional setup would be to look for a tighter integration
between Rivendell and Samba4 AD and or MS AD as part of Rivendell

Well, it all depends on your use case. But first, the low-hanging 
fruit: PulseAudio.


The use case for which PulseAudio was designed is ‘general desktops’ 
—i.e. playing the various beeps, boops and other sound effects 
generated by a GUI in the course of its normal operation when running 
typical ‘office automation’ type applications (web browsers, word 
processors, etc). As such, it has no place on a system designed to 
handle pro audio. It’s one of the first things I typically disable on 
any new Rivendell system.


Well, I agree with you, it depends on the use case : Most of my 
customers are community radio stations. The computers they use are 
multi purpose. They can be used for office suites as well as sound 
editing with audacity as well as browsing the web, or use rdlibrary to 
encode carts. For them, it is quite common to have only the 
motherboard integrated sound card, and it is hard to cope with this 
device being exclusively used by caed with an alsa setup. They DO need 
to be able to listen to songs on the net, then integrate them in 
Rivendell and set markers in rdlibrary, all in the same session. For 
them, having a sound daemon in between allowing concurrent access to 
the sound device is a must. And sometimes, programs does not know how 
to speak JACK protocol, but they know how to speak alsa/pulseaudio 
language.


Hi, here I dare to add that, in my own experience (because often I do 
test in my own laptop) that's what I'm usually doing by combining two 
pieces:


Jackd in promiscuous mode is one of the pieces... because then, I can 
bridge my user-space jackd apps to and from Rivendell ... but still, I 
need to have a sound card for 'regular' apps.


Here comes the second part, my solution (no pulse audio here) is to 
start jackd against the laptop sound card (and not a dummy interface, as 
I do in my mockup Rivendell terminals), AND setup an ALSA-to-JACK bridge 
configuration (it is documented around in internet, it is done through 
an .asoundrc file that adds user-overrides to ALSA config). This second 
piece includes setting as ALSA's default audio interface the 
ALSA-to-JACK bridge virtual interface. This way, any non-jack-aware apps 
will happily play audio to jackd fully unaware/transparently :-)


The only caveat for this approach is that, for sound cards that do 
feature sub-devices (such ASI cards) jack only gets the physical 
ins/outs of first subdevice... but this is fine for an integrated 
mobo/laptop sound card.


With pulse audio (I don't use it) in theory all this should happen 
(AFAIK) automagically...


I could share my .asoundrc config file for alsa-to-jack bridge (also, 
that may need extra packages installed)


Cheers.

I agree, rivendell exclusive access to the sound device is also the 
way I usually sets rdairplay dedicated machines up, but it is less and 
less common for my customers to have this kind of dedicated machine.


As for JACK’s promiscuous mode, I’m not quite sure what you mean by 
calling it ‘unsupported’. It’s present in the stock tarballs and 
binary downloads available at the canonical JACK GitHub site, so it’s 
certainly ’supported’ by the primary JACK developers. Whether its use 
is *appropriate* in a given situation is a matter of professional 
judgement. Does it open new avenues by which a system could be 
compromised in some way? Sure. So does giving a user an account on 
the system. So does turning on the power on the computer in the first 
place. I think the more relevant question to ask is: does it provide 
additional capabilities sufficient to justify the additional risk? 
The standard security principle of ‘least privilege’ holds that a 
user should have no more power on a system than the minimum necessary 
to do their required tasks. Given that Rivendell's previous, 
“non-promiscuous mode” JACK setup required that users run all JACK 
audio applications as ‘root’, I have to imagine that this change 
makes for a vastly improved security posture in general.
Well. "unsupported' may not be the correct term. I've read some ML 
posts talking about this options not being supported, but probably 
they meant it did not represent the most widely used configuration. On 
the security matter, I agree with you, there is a trade-off to find,

The way I do works just like a charm to me, where everything 
integrates an inter-operates to perfection: I'm using the jackd2 
PROMISCUOUS MODE feature to create a single, system-wide, 
user-interoperable, jackd service, that act as a hub to any jack 
client, of any user (thus Rivendell) on the whole system, allowing 
each user (the workstation user) to manage their GUI clients and/or 
applications using GUI tools and send/get audio to/from any other 
audio clients on the system.


In this mode, Rivendell automatically connects to the system-wide 
jackd server.


In the same way, qjackctl (or any other GUI applications, jack 
manager/client, etc... for instance, I use Ardour as Rivendell's 
mixer, and jamin as DSP) by means of X11/dbus does automatically 
detect and bind to the system-wide, shared, running jackd server... 
automatically.


I had posted specific setup details (Debian) before in this list if 
you're interested on.

Hi Alejandro

Thanks for your answer. I remember this discussion we used to have 
together ;)


I just had a look on it and as you said, you are an advanced user, 
system programmer, and don't rely necessarily on distros sound stack 
(pulse, dbus), which is perfectly fine in your case. The promiscuous 
mode also exist for pulse audio (well, a kind of promiscuous mode) in 
order to have a system wide daemon running.


unfortunately, either promiscuous mode in jack or system-wide daemon 
in pulse-audio are configurations not recommended nor supported. And 
as I'm trying to provide a solution for average users and rivendell 
administrators, who are not necessarily system administrators, I would 
like to avoid as much as possible unsupported or not recommended 
solutions. Moreover, since it deals with shared memory, relaxing 
permissions on such files may introduce security flaws.


By the way, I could not find a way to start Jackd in promiscuous mode 
through dbus. If you have any clue, I would be pleased to test it


Thanks and regards

2021-12-02 Thread Alejandro olivan Alvarez

I'm posting new reply on this thread since, to my joy, as of beta4
commit
https://github.com/ElvishArtisan/rivendell/commit/3c4e2bd6d7dda1a730d1d8f6fb6754bb76d1530d
released tonight, the whole picture regarding Rivendell/Jackd
integration in recent systems may very much change for some of us Jackd
fans: Rivendell is coming now with out-of-the-box promiscuous mode
support... yay!!! :-D

So, it is time now to drop old hackish practices and switch to the
intended/ortodox packaged ones for the jackd integration with
promiscuous mode, which raises me some questions (at this point, I guess
just Fred can answer) about overall how the new picture is:

- Does a rivendell handled jackd instance (defined in RDConfig)
automatically run in promiscuous mode for the 'audio' GID? or has to be
somehow 'enabled'?

- While regular users are already set as 'audio' members (very clever
move selecting audio as the promiscuous GID!), now the package seems to
be handling the environment variable part, pointing to the 'audio' GID,
but... is it system wide? or does user-space launched applications have
to initialize it?

Thank you very much for such a new feature!

Best regards.

Hi everyone.

I'm trying to streamline the integration of Rivendell 4 on lubuntu or 
other debian based distros using modern tools such as systemd and 
DBus. Now, qjackctl and the packages jackd2 uses Dbus to launch jack 
daemon by default. This provides some cool features, notably the 
handshaking with pulseaudio in order to release the alsa device from 
pulse and let jack use it instead, and also the automatic connection 
of pulseaudio into jack as a client.


The way qjackctl launches jack is by issuing the "/usr/bin/jackdbus 
auto", then setups and actually starts jack through the DBUS interface 
with /usr/bin/jack_control


I would like to mimic this behavior in order to make rivendell service 
(well... caed) start Jack this way with an external scirpt, but it 
fails when trying to connect jack. The logfile says "Unable to 
communicate with JACK server". Obviously, the actual jack server may 
take too much time to launch and it is not ready when caed tries to 
connect. DBus provides a way to check the status of jack. Maybe just a 
pause could be sufficient to allow jack to start before trying to 
connect to it.


Would it be possible to take this way of launching jack through DBus 
into account so that it can be started at boot time with caed instead 
of waiting for a user session to begin ?


By the way, I tweaked systemd service for rivendell (sudo systemctl 
edit rivendell) in order to start the daemons with another user 
(actually the user who starts the session afterwards to use Rivendell 
tools) so that I can launch qjackctl or other tools with this user and 
modify the patching of clients without being forced to connect as 
root, which is not recommended on ubuntu/debian. Maybe, it could be 
useful to be able to select the user for each sub-service in rd.conf,

The way I do works just like a charm to me, where everything integrates 
an inter-operates to perfection: I'm using the jackd2 PROMISCUOUS MODE 
feature to create a single, system-wide, user-interoperable, jackd 
service, that act as a hub to any jack client, of any user (thus 
Rivendell) on the whole system, allowing each user (the workstation 
user) to manage their GUI clients and/or applications using GUI tools 
and send/get audio to/from any other audio clients on the system.


In this mode, Rivendell automatically connects to the system-wide jackd 
server.


In the same way, qjackctl (or any other GUI applications, jack 
manager/client, etc... for instance, I use Ardour as Rivendell's mixer, 
and jamin as DSP) by means of X11/dbus does automatically detect and 
bind to the system-wide, shared, running jackd server... automatically.


I had posted specific setup details (Debian) before in this list if 
you're interested on.


Best regards.

[RDD] DTMF detection in Rivendell

2021-11-16 Thread Alejandro olivan Alvarez


Hi list!

From what I've recently learn, audible tones (DTMF tones I've been 
told, although I recalled DTMF acronym to be telephony related...) in 
radio networks, due to its simplicity and, more importantly, low cost 
(drop satellites!) are becoming somehow by paradox (I've been told that 
for years, DTMF tones where considered a matter of 
amateur/non-profit/tiny radios... being satellites used for the 'pros') 
the preferred way to trigger events here (Spain)... Even top-tier, 
nation-wide radio networks, have switched to audible tones (I had not 
realized about that, but now, paying attention, I hear them!) and have 
dropped satellite signaling costs.


This triggered me a question immediatelly: On Windows-based automation 
systems, DTMF detection uses to be included as a feature, so... how does 
the Rivendell community users handle this!?!?!?!


Googling around, I've found this: 
http://wiki.rivendellaudio.org/index.php/How_to_trigger_events_from_tones_on_your_network


Although somehow old, and basically pointing to the usage of a Windows 
software under Wine, that tells me that the need, the use-case, is 
there... and has been dealt by someone.


I've also found references for some linux tools, like multimon and 
multimon-ng, even Node/NPM libraries, being able to detect audio tones 
under Linux, but not much user-friendly... so:


How do you handle this? What are your approaches to handle DTMF and 
trigger RMLs... Wouldn't be nice to have RDCatch to be able to 'catch' 
tones?

To add to Fred's comments about the Fades: Ideally a station would modify
their songs for trims, fades, and levels before they are brought into
Rivendell. So the only thing the playback system would need to know about

we take the easier way out and use the RDLibrary controls.


Adding a +1 for this comment.  I am no longer in the commercial end of 
the business, but rather, with a non-comm; however, I would think the 
fade up and down ability is more important than ever.  The 2 biggest 
radio chains operating in town have eliminated the job of production 
director and the production studios are no longer maintained with 
their switch to contract engineers, who are only called when something 
in the main studio dies completely.  Whereas the production director 
used to comb and massage every bit of audio that was carted, including 
the segue cue at a cart’s end, audio is now added with no production 
pre-prep at all.


Although out of original topic... this comment has caught very much my 
attention.


I don't work, directly (although I do indirectly, since I'm in charge of 
cloud/networking operations, mostly streaming services) with/for radio 
stations, but my colleagues of the automation-systems do... and I'm very 
much interested in their talks and experiences, and, from quite a long 
time, an important part of their comments go in that direction: costs 
saving via maximize efficiency, being a main way to achieve that by 
moving from more, specialized job profiles, to less, more flexible 
profiles paired with more automated/integrable/flexible tools... and 
this is having a HUGE impact in the radio automation market (AFAIK, here 
in Spain and parts of Latin America... some rumours of France somehow 
the same)


And that puts the radio automation system right on the spot, more 
specifically, the INTEGRATED MULTI-TRACK EDITOR feature... to the point 
that a few EU companies here (AEQ, Dalet, XFrame) along with RCS and 
OmniPlayer are getting the upper hand (with competitors such Hardata 
rushing to implement that) with contracts falling by absence/presence of 
that fancy feature. I barely know about it but it seems that it allows 
changing internal workflows, thus, enabling job cuts  is that the 
trend around?


Best regards.



In fact, we do not have a production department, either.  We don’t 
play the count-off or extraneous studio talk prior to the musical 
start of any song (except for “Daydream Believer”), and we fade out of 
any applause quickly.  All that is done with the fade up and down 
markers.  I would think with the contraction of jobs in commercial 
radio the ability to fade within Rivendell would be more important 
today than in the past, when everything on-air, first passed through a 
production department.

Hi!

Now I think I got it:

Start-Mark defines both, the point from which cut content will be played 
(discarding anything before it), and, if a Fade-Up Mark is set, it is 
also the starting point of a logarithmic fade-up span, that goes from 
the Start-Mark itself to the Fade-UP mark. Therefore only a Fade-Up mark 
can exist, and it is set after the Start-Mark. In the absence of the 
Fade-Up mark, audio will be played, at full level, right from the 
Start-Mark.


All this applies to the End/Fade-Down Marks, but conversely, in the 
sense that the Fade-Down Mark, if set, it is before the End-Mark, 
defining the starting point of a logarithmic fade-down span, that ends 
at the End-Mark. End-Mark acts as both, fade-down span end mark, and 
content boundary mark. In the absence of the Fade-Down mark, audio will 
be played, at nominal level, right to the End-Mark. Content after 
End-Mark is, therefore, never played anyways.


When setting up Fade Marks, in the Cut/mark editor, the actual 
pre-listening does not reproduce/perform the actual logarithmic fade-up 
effect that will be aired by RDAirPlay. A normal, not faded, pre-listen 
playout is played instead, just to help determine where, exactly in the 
waveform, the mark is set.

the presence of such mark imply that everything before the mark gets
muted? or, on the contrary, the mark indicates the point where/when
full level is reached AT?... and, if so, where in time does the
fading up starts? could someone clarify?

The ‘base points’ for FadeUp and FadeDown are the ‘Start’ and ‘End’
markers, respectively; with the ‘mute level’ being (rather
arbitrarily) defined to be -46 dBFS (-30 dB from the “reference level”
as shown by Rivendell’s meters. The fades (both up and down) are
logarithmic, meaning that they should be perceived as being “uniform”
to the typical human listener.

Nice to know! logarithmic fading.

What I have to figure up is whether Fade Up mark goes BEFORE Cut start,
to achieve the fading UP or not.

And the inverse at the end of track: first Fade-down being reached,
triggering fade down until reaching End-cut.

With all of that said, I’ve found that FadeUp and FadeDown are very
seldom used at most Rivendell sites. There are a couple of niche
cases, but they are quite rare. Were I redesigning the cart/cut model
from scratch, I would very likely drop those two functions entirely.
Curiously, those marks (provide they do what I think... and/or I manage
to learn how to use them correctly) would be very very useful to me (and
for any Dance/Electronic music radiostation). Because, for some tune
styles (mostly trance music, but also techno, minimal house, deep
house anything non-commercial, either deep or chill) you don't want
a 'radio edit'; there's nothing wrong to have a full, or almost-full,
length track aired including most of its in/out bases... but you don't
want them to start right at full level from the very first beat either,
but rather a short, smooth fade up for the first bar.

Cheers!

Re: [RDD] Understanding Fade-UP and Fade-Down markers

2021-10-25 Thread Alejandro olivan Alvarez

Hi! Thenk you for your help... now a possible inter-relation between 
Start/End markers and Fade Up/Down markers pops up... Regarding the 
other marks, your explanation is a nice and clear explanation.


On 10/25/21 6:07 PM, Mike Carroll wrote:
I can't speak to the actual levels that are involved, but here's how 
we use the markers.


  * Cut Start - Airplay starts playing the cut wherever this marker is
placed; anything before the marker is ignored. We use this to drop
excessive intro chatter in live cuts, and in one case to drop out
an obscenity at the start of a song.
  * Cut End - Airplay ends playing the cut and starts the next cart.
We use this to drop bad edits on live cuts, where the start of the
next song is included in the cut.

The problem with the start/end markers is that the Airplay output 
level is at its normal setting. This can cause abrupt-sounding 
transitions from one song to the next.  The Fade settings can help 
with this.


  * Fade Up - Airplay starts playing the cut at "silence" level at the
beginning of the marker, then increases the level to normal by the
end of the marker.  We use this to soften the beginning of live
music, where there may be an abrupt edit between two cuts.

Ok... Here's the point, and my confusion, because I ONLY have 1 mark, 
the FadeUP mark, I don't see any possible interval... I quote your mail:


'Airplay starts playing the cut at "silence" level at the beginning of 
the marker'


...but which Marker? The Start Cut? or Fade-Up Marker itself?

Or do you mean I can put Fade-up mark BEFORE Cut-Start mark? defining, 
now with two marks, an effective fade UP interval? ... if so, my 
understanding of Cut-Start Mark is that, it sets the point where the 
content starts, ignoring anything before it UNLESS a Fade-Up Mark is 
define, in which case, Cut-start mark behaves differently... this is the 
point I don't understand



  * Fade Down - Airplay starts fading the cut at the beginning of the
marker, reaching "silence" level at the end of the marker.  We use
this to soften applause after live cuts, or to force a fade on a
song that ends abruptly.

Note that RDLibrary does not perform Fade Up or Down when you're 
playing a cut in the waveform editor (at least in Riv2).


The Segue settings give you more help with cart transitions.

  * Segue Start - Airplay starts fading the cut to "silence" at the
beginning of the marker.  This continues until Segue End.
  * Segue End - The cut is a "silence" level by this point. Airplay
ends playing the cut.

The difference between Segue Start/End and Fade Down is the Airplay 
will start playing the next cart at the beginning of Segue Start 
rather than at the end of Fade Down.  This allows you to overlap carts 
for segues.  Note that the Segue markers are ignored unless you have 
"segue" set as the cart transition in your logs.


These other markers aren't used by us:

  * Talk Start/End - This turns the Airplay time indicator blue at
Start, returning to normal color at End. This is used to let the
DJ know it's a good place to talk over the music.  The setting
doesn't do anything else that I can see.
  * Hook Start/End - This marks a section of the cut that will be
played in Airplay when a Sound Panel button is pressed.  It's
controlled by the "Play" setting on bottom of the Sound Panel -
"Play All" or "Play Hook".

Mike

Hello all.  Thought I would throw my 2 bits in on the Riv/Jack stuff.

I found the working combination on CentOS for me was the following:

Add a startup entry into the Session manager to start QJackCtl with sudo.

Once QJackCtl starts up with its settings, in options, you can run 
some scripts.
I've run 'service rivendell stop' as the Execute script on Startup, 
and 'service rivendell start' as the Execute script after Startup.  
This allows jack to take over the alsa device.  I have disabled 
pulseaudio, and I think removed most of it without breaking dependencies.


Once QJackCtl runs, then you can start whatever riv apps you need.

I don't recall if I had the audio card selected or unselected in 
rdalsaconfig


I tried duplicating this setup in Ubuntu Studio to try and mess with 
the new Rivendell, but too many dependencies to work around to try and 
get QJackCtl working so you can see the patchbay to connect Riv to 
inputs and outputs.   May be another wet soggy weekend project.


I'm using Debian, not Ubuntu, and I'm having total success in using 
Jackd/Rivendell (I'm not sure, but think shared my setup on the list in 
the past) both in physical, virtualized and hybrid environments, by 
using a somehow 'dark' way of using Jackd: The PROMISCUOUS MODE.


Essentially, this mode breaks the default rule of jack users isolation. 
This way, while some Rivendell processes are ran by root, others by the 
logged-in user (others maybe by pypad, rivendell, or any other...) they 
all can transparently connect to a same, shared, jack daemon.


In fact, I setup a default, single, system-wide, root run, jackd systemd 
service... where rivendell connects to (transparently) and user 
applications too.


The PRO of this setup is that I can Integrate Rivendell with the mature, 
proven, and powerfull Linux Digital Audio Workstation way of working 
that the studio/musician Linux community users have enjoyed for years: 
In fact, the ONLY connections I do on Rivendell is to Ardour (to act as 
its DAW interface) so I could use any Mackie controller such as the Zoom 
R16 as a mixer, and I can use qjackctl WITHOUT starting a jack server 
(it detects and connects directly and automatically to the system's 
jackd server) to setup and save my patchbay. The user can, that way, 
through nice GUI tools, use transparently applications such as Jamin 
Sound Processor, GlassPlayer, GlassCoder, etc...


The 'CON' of this setup (as Fred once pointed out) is that all the 
configuration and work gets outside of Rivendell's database and, 
therefore, is not portable or saved.

You could approximate this in a few ways with rdairplay that I can 
think of off hand immediately, all end up putting the show name as 
part of cut metadata.
This is interesting... I'm wondering wether it could be possible to use 
an AuxLog Machine or an VLog Machine to have a pure do-nothing 
MACRO-cart log that just keeps track of the Station's Show/Grid/Schedule 
metadata. The thing is that I don't know wether you can differentiate in 
the pypad scripts metadata coming from one logmachine or another.


Alternatively you could make a custom pypad script that checks the 
current time against a program list or database and prepends the result.


Yep... the Linux people way :-)

Hi list.

I don't know much about radio automation (Rivendell is my first

the thing is that over the years I'm quite used to see our
customers to
include in their stream metadata (usually the current song on
Icecast2)
the name of the show, other radio/program data, together or as a
replacement with the classic artist - tittle song metadata.

For example, I'm used to see things such as "Morning Show by Johnny
Public - 06:00 to 12:00 - SomeArtist - SomeTitle" and complex things
like that.

When I asked the Automation guys from where does that stuff came for,
they naturally answered me something like: "that is generated from
the
automation system, the automation system has everything about the
radio
on its database: the program grid, the scheduling, every piece of
songs
or recording metadata, everything is there... so, it generates that,
much like classic RDS, etc ..." which I found fascinating (that
was my
first way to clearly appreciate a difference between the 'automation
system' and a regular playlist software).

Now... with Rivendell, I have learned how to use pypad scripts to
taylor
an artist - title (or some other cart metadata stuff) stream

[RDD] Pypad Now-Next update for Radioshow, Grid, Schedule metadata

2021-08-31 Thread Alejandro olivan Alvarez


Hi list.

I don't know much about radio automation (Rivendell is my first serious 
approach) but I fairly know about streaming (that's part of my job) and 
the thing is that over the years I'm quite used to see our customers to 
include in their stream metadata (usually the current song on Icecast2) 
the name of the show, other radio/program data, together or as a 
replacement with the classic artist - tittle song metadata.


For example, I'm used to see things such as "Morning Show by Johnny 
Public - 06:00 to 12:00 - SomeArtist - SomeTitle" and complex things 
like that.


When I asked the Automation guys from where does that stuff came for, 
they naturally answered me something like: "that is generated from the 
automation system, the automation system has everything about the radio 
on its database: the program grid, the scheduling, every piece of songs 
or recording metadata, everything is there... so, it generates that, 
much like classic RDS, etc ..." which I found fascinating (that was my 
first way to clearly appreciate a difference between the 'automation 
system' and a regular playlist software).


Now... with Rivendell, I have learned how to use pypad scripts to taylor 
an artist - title (or some other cart metadata stuff) stream metadata. I 
also have learned how to use a MACRO and empty/bogus carts to put 
now/next metadata even if no log machine is playing ... but, how do you 
guys manage to put your show info in the Now/Next data?


I don't find anything about that... can it get data from a clock 
configuration? or how do you approach this?

For standard production setups, that’s an OS-level setting. The
easiest way to do it on CentOS 7 to use the ‘system-config-language’
tool. You may need to install it; just do (from a root shell):

yum install system-config-language

However, if you’re just hacking Rivendell and don’t want to change the
whole system over to a different locale, you can do it by setting the
‘LANG’ environmental variable to the desired language. For example, to
switch to Español, you could open a shell (non-root) and do something
like:

export LANG=es_ES.UTF-8

Rivendell modules run from that same session will then attempt to use
the appropriate translation.

Thanks for the feedback... Because I'm very influenced from MS windows
apps philosophy when it comes to radio automation (I don't use windows
personally :-) I was expecting the typical UI option... Then, soon after
mailing, I actually though on just switching the terminal LANG env var
to whathever, I set to deutsch, launched rdairplay and tada!
german!... then french, spanish ... so simple, s linux, I love it!

While we’re on this subject: the translations currently in Rivendell
are extremely long in the tooth, with the last updates done way back
in the v2.x era, so I suspect that coverage for any given language is
quite ragged. As we converge towards a production v4.x release, we’ll
shortly be in a position to start soliciting volunteers to update
translations. Stay tuned!

I actually read a little on the wiki about making translations ... I
have to calmly refresh my rusted .po skills, re-read the
language/translation documentation on rivendell, and evaluate whether I
could help... I definitely would like very much to help translating to
Spain-Spanish, Catalan (And eventually I know people that could also
provide me translation to Euskera)

[RDD] MD Macro minimum level

2021-07-19 Thread Alejandro olivan Alvarez


Hi list.

I've been testing the MD macro to 'duck' (In reality I'm using it to 
simulate automated 'fade' ins/outs) the MainLog machine (I've also 
tested with the Aux1 Log Machine)... and I would like to have a certain, 
valid, numeric range for the level value that the macro can be used 
with... I think we cannot happily put there any value, for instance, 
here's a situation I found:


Trying to simulate a 'fader-down' situation, I set the value to -40, and 
it seemed to work. Using -50 but, seems to make rivendell (caed?) 
unhappy and issues trigger in (RDAirplay acts weird, VUMeter goes red to 
clip... clearly -50 is a no-go), the thing is that, at -40 value, I can 
still hear some audio 'leaking' out... sure, I could test every value, 
one by one, but I guess it is better to ask and have an explanation on 
the the actual right values...could you help?


Conversely, to 'fadde-up' the logmachine to its nominal level, I used 
the 0 value, and no problem... but, I bet, positive values beyond 0 are 
not allowed... or are they?


Thank you very much in advance.

The PAD for the current ‘default Now & Next cart’ that the ‘SN’ macro

Hi! thank you so much for your help!

It's not entirely clear to me the 'machine stop-down completely'
(probably still not enough radio/Rivendell jargon in my mind) maybe I'm
wrong, but, translating it to me as 'completelly ending the current
playback', that would somehow explain the behavior I experienced.

With that interpretation, the machine has to be running (well, what I
think of 'running'.. executing the log... i mean, no PS), so, the SN
cart that I execute NOW, will be sent to the server after/once the
current song on the machine ends (and, therefore, it is time to send a
new metadata to the streaming server).

Adding PS on the MACROs in my tests, seemed to do the trick... Now I
explain that as those PS gave time to completely end the current song,
and then update the streaming Server, and then, even issue a PS afterwards.

Just to amplify Alejandro’s point: directly modifying the Rivendell

Specifically, the database schema CAN and DOES change between
different versions of Rivendell; meaning that the update method that
worked perfectly three months ago could end up NUKING YOUR DATABASE
next time around.

A much better and safer method for making these sorts of site-specific
bulk changes is to write a script that uses Rivendell’s WebAPI. See:

<http://opsguide.rivendellaudio.org/apis/web_api.pdf>

Man, I missed the API completely during all this time ... thank you for
the remind and the pdf link!

The Web API is a documented, public and above all stable interface;
using it will allow you to write scripts that won’t break across
different versions of Rivendell.

N.B. — If you insist on writing changes directly to the DB, be sure
that you have a known good backup of it first. The sanity and gray
hair (not to mention job) that you save may be your own.

I want to bulk update the scheduler codes for my songs based on the YEAR field,

Sample SQL to add my 70s scheduler code to songs is:

CART where YEAR > str_to_date(‘1969’, ‘%Y’) and YEAR < str_to_date(‘1980’,

At first glance, I bet you can just use LIMIT on the subquery... and the 
specific (first) problem you encountered should be bypassed BUT... I 
don't think that being a good idea.


At first glance, I see you're trying to insert TWO values into TWO 
fields (CART_NUMBER, SCHED_CODE) whereas you're subquerying for just ONE 
value (NUMBER) so I bet you'll need an additional field or the DBEngine 
may complain on that too.


Then for the subquery itself, consider that If there are more than one 
result/row, you should decide which one is the right one... the DBEngine 
will never consider itself powerfull enough to impersonate you and take 
that decission by you... you have to tell it the criteria for such 
decission and the criteria must throw a single row, so you'll never 
could blame on the DBEngine for selecting the wrong one :-P


Are all the subquery results equal? well... in that case the LIMIT trick 
could be enough, why not, but otherwise, you have to, at least try 
GROUPing BY and/or ORDERing BY the subquery results following your 
intended logic (and if the logic is complex maybe grouping/ordering 
wouldn't be enough... JOINining, etc... hopefully GROUing/ORDERing BY 
will be enough)


My advice is that, first, you JUST work on the subquery ( just SELECT) 
playing with grouping, ordering, limiting (or whatever be necessary) 
until you get just the TWO unequivocal values you want to insert, from a 
SINGLE unequivocal result row... then paste that final query as the 
subquery of your 'parent' query and it should execute.


Good luck, and best regards!



This throws an error because the sub query returns more than one row. Any 
suggestions for correct SQL or a better way of doing this?

[RDD] Send Now-Next MACRO behavior

2021-07-13 Thread Alejandro olivan Alvarez


Hi list.

I'm experimenting with the SN macro to put arbitrary Current Song on 
Icecast2 streams (well, to any purposes I guess)... but my success is 
partial... the behaviour of the macro is somehow strange, since it seems 
like if the update of the NOW pypad metada gets 'queued' or is kinda 
async... I'm not sure, I don't understand the results.


What I've done is to create some carts (I think of them as 'stream 
metadata-only carts'), with arbitrary artist - title metadata (some 
carts have even no cuts at all within, some have just a 1sec pip tone) 
that I want to display as Icecast stream current song. I created an put 
into the log some macro carts which have, in its code : SN now 1 1X 
(where 1X represent one of those 'stream metadata cards')... and it 
works like partially...


I'm tailing syslog and look for the pypad updates trying to figure out 
the logic on how the thing works: it seems as if the macro execution 
conflicts somehow with the now of the actual log songs. Sometimes 
the now seems to be ignored, sometimes gets like 'queued' and upon 
some other event it finally gets executed.


A curious case is when I schedule a macro cart in the log that stops the 
log machine and switches to an external audio source, the idea is to do 
a last now update so the resulting Icecast2 stream will display 
something like 'foo - is now live from bar' ... I can see the 'SN now 1 
1X' on the machine, but the pypad never 'catches' the update.



How are you using that? is that conflicting with groups with now 
enabled? What is the realtionship with the status of the logmachine? I 
don't get this one..

Hi list.

Today I've created in RDAdmin a pair or report setups (I think that the 
documentation of the form is missing on the operations guide... I guess, it is 
probably all self-describing for experienced radio broadcasters, but I would 
like to have some points of what are those fields for) ... so far, so good, 
playing around a little, I managed to generate some reports in plain-text 
format (nice to see the path supports wildcards)...now:

- Could that be scheduled? ... I've not found an appropriate macro cart for 
that and there's not the option in RDCatch either

On the other hand, the operating guide states as a good practice to regularly 
clear old/unwanted report data (I guess that would prevent having an endless 
data feed into the database)... I couldn't agree more with that.

- But, could that be also somehow automated?

Thank you very much in advance.

pypad.py which needs to be copied to /usr/lib64/rivendell/pypad


 cp /usr/lib/python3.7/site-packages/pypad.py /usr/lib64/rivendell/pypad


That doesn’t look right, on a couple of levels.

First, ‘/usr/lib64’ is a RedHat-ism. Ubuntu at least doesn’t seem to 
use that convention at all, but rather installs binary linkable 
objects under ‘/usr/lib’ regardless of the target arch. I’ve not 
actually checked on Debian, but I’d be somewhat surprised if things 
are different there as Ubuntu seems to copy Debian pretty closely in 
general file layout.


Second, while the PyPAD scripts themselves (think of them as ‘user 
programs’) do indeed need to go in ${libdir}/rivendell/pypad (which 
evaluates to ‘/usr/lib/rivendell/pypad’ on Debian-is setups), the 
PyPAD *library module* should go in the default system location so it 
will be in Python’s search path. On Ubuntu, this location is 
‘/usr/lib/python3/dist-packages’.


N.B. Python supports the concept of having multiple parallel 
installations of different versions, each of which get their own 
orthogonal module store. On my UbuntuStudio 20.04 setup, the default 
installation has installed no less than four different versions of 
Python, resulting separate module paths for each (in my case, 
‘/usr/lib/python2.7/dist-packages’, ‘/usr/lib/python3/dist-packages’, 
‘/usr/lib/python3.8/dist-packages’ and 
‘/usr/lib/python3.9/dist-packages’). These locations appear to be a 
Debian-ism inasmuch as Automake's AM_PATH_PYTHON() macro doesn’t 
recognize them, instead using the expected standard Python defaults. 
At present, there is a nasty hack in ‘configure.in’ (lines 290-305) 
that attempts to detect this situation and install things the ‘Debian 
way’ if necessary. I would love some feedback on how this works on 
various Debian-ish setups (or, even better, PRs that improve the 
heuristic).


My tests are being done on Rivendell master, using Debian packages that 
I barely build myself using debuild... So no surprise I doesn't install 
well being a RedHattish source.

Ok, first thing to do is verify that your Icecast2 system will accept 
metadata updates from your PyPAD host. Icecast is famously picky in 
this regard; updates *must* originate (or appear to it to be be 
originating) from the same source IP address as the encoder client 
originating the stream; updates that fail to meet this criterion are 
ignored. A good way to test this is to attempt to send a metadata 
update *from the same system that is running the PyPAD script* 
manually via a curl(1) command of the form:


curl -u source: 
http://:/admin/metadata?mount==updinfo=


where:

- The hostname or IP address of the system running Icecast

- The TCP port number of the Icecast instance

- The mountpoint of the stream

 - The mount point password.

- The string to set, encoded as specified in Section 2 of RFC3986

For example, to set a string of "The Beatles - Hey Jude” at an Icecast 
instance running at "icecast.example.com:1234 
<http://example.com:1234>" with a

mountpoint of “MyStream” and a password of “hackme", the URL would be:

curl -u source:hack

Local/Regional/traffic-terminal lab  So far, so good, it works and 
I'm very happy, I'm learning a lot of this world! ... now but, comes the 
issue:


Since I don't have physical stuff, including an audio switcher (I'm 
using everything software: jack interface, Local Audio Switcher on Jack 
interface, audio sharing through jacktrip, and commands between head and

could be very much possible) my switcher is Rivendell Jackd interface as 
Local Audio Adapter. Here SA and SR macros do work. They're in fact the 
foundation of my setup: I can use SA/SR to program relaying audio from 
header or play local stuff instead.


My problem is that while SA does work, SX seems to not (or I'm failing 
completely somewhere). Ideally, What I would like is to be able to use 
SA to gradually (some seconds fading-up) return back to head/master 
audio content after a local traffic-break. I know this is not possible 
out-of-the-box, but I feel I could fake that using SX (or SL?) ... but 
they seem to not apply to my Jackd interface (Interface number 1) 
crosspoints. Here's a sample commands


- This works: switch from content coming from master (in enters in 
rivendell's jackd input 7L/R, so, input 8 on the switcher) and the 
removal/reverse command


SA 1 8 1

SR 1 8 1

- And this are my attempts on trying to control the crosspoint gain 
after SA it:


SX 1 8 1 -40! (try to set the crosspoint to -40 dBFs)

SX 1 8 1 0! (try to set it to 0)


Is that the way SX is intended to be used? wrong syntax on my own? Has 
anyone tried this or something similar?


Thanks, regards.

Re: [RDD] Auto Mount of /var/snd On reboot Does Not Work

2021-06-28 Thread Alejandro olivan Alvarez


Hi All.

On 6/28/21 4:23 AM, wa7skg wrote:

Thanks, but nope. Still doesn't mount on reboot.

Michael


I would like to just drop some ideas here (hope not creating further 
confusion)


- First and foremost, in my (short) experience with Rivendell (using 
Debian as base OS), I initially used the traditional approach of fstab 
the /var/snd mount for the audio storage on the radio network 
mockup/labs  just to realize that, in reality, when acting as a 
client, rivendell manages by itself the mounting of /var/snd (this is 
not probably, enough documented or highlighted due to its importance, in 
the documentation) by means of AUTOFS (so, in debian, I had to install 
the autofs package). The autofs parameters (very very similar to those 
on a regular fstab) are provided in /etc/rd.conf ...here's an example:


[AudioStore]
MountSource=192.168.1.254:/var/snd
MountType=nfs
MountOptions=rw,rsize=8192,wsize=8192,timeo=14
CaeHostname=
XportHostname=

It works very well to me and it is the 'native' or 'rivendellish' way to 
mount /var/snd on the client terminals... Moreover, I think it is worth 
to investigate on the /etc/rivendell.d multi-config, rdselect and 
rdmonitor because it all it deals with multiple, remote, storage (and 
database) mounting/umounting very very nicely (I have learnt to have, on 
every terminal on the radio network, two configurations: a local DB and 
/var/snd storage config, so it can go 'standalone' , and the networked 
DB / NFS /var/snd config)


- Regarding pure fstab issues (again Debian here) I would like to share 
that I have had issues too in the recent past, as the operating system 
moved deeper and deeper into the realms of systemd management, and I 
discovered that classic _netdev and other tricks didn't work anymore, 
and some new fstab options are usually required to make systemd managed 
machines to mount shares at boot.


If your system is systemd handled (I guess it is) I would look for and 
give a try on some fstab options such as x-systemd.automount , 
x-systemd.device-timeout , etc...



Hope this could help

Best regards.

Re: [RDD] Macro cart RML execution: parallel or sequential?

2021-06-17 Thread Alejandro olivan Alvarez


Hi.

Thank you so much for your help!

On 6/17/21 12:25 AM, Mike Carroll wrote:
They are run serially - but the operations may be asynchronous because 
the commands may be run by some other process.  Here's an example.  We 
load logs via RDCatch using a macro cart, and we want anything that's 
currently running to be faded and stopped before the new log gets 
loaded.  There are three commands:


*PS 1 4500! *
"Press stop on main machine, fading to silence after 4.5
seconds."  This command is run asynchronously by RDAirplay, so as
far as the RML interpreter is concerned the PS is complete as soon
as it's sent to RDAirplay. That means the next command in the
macro cart will run immediately.

*SP 5000!*

"Sleep for 5 seconds."  This command is run by the RML
interpreter, which forces it to pause executing commands for 5
seconds.  That allows the *PS* to complete, plus an extra .5
seconds of silence for listening space.

*LL 1 logname 0!*
"Load log in main machine and begin execution."  This command is
also run asynch by RDAirplay.


If we don't put the sleep command in the cart, the LL will begin 
executing immediately after the PS.


Man... That explanation, followed by that example, deserves to be in the 
documentation :-O ... crystal clear!




NN does nothing.  SP pauses the RML executor for the specified interval.

Not familiar with MT, sorry.

The RML appendix shows what process handles each command in its 
description.


Mike

MT, after your explanation, is also clearer to me: as the macro 
including MT reaches the MT line (sequentially) it will start a timer at 
the end of which, the provided macro-cart number will be, in turn, 
executed... My bet is that, following the logic, the MT line would be 
reached sequentially and then run asynchronously on its own, so the next 
line will be executed (and eventually even end) while the timer will be 
ticking. The MT invoked cart after the timer ends I assume will be a 
completely new and independent process on its own... What I'm not sure 
is whether the timer itself is run sync or async in respect to the MT 
container macro-cart (count down 'locking' the cart as in execution 
until it ends) I have to try it

After the LL Macro, you need a MN Macro (Make Next). But you need to
calculate the time at which to start the Log outside of Rivendell, in
the script where you are sending the Macros. This is where it becomes
somewhat difficult. See the comments in the script I wrote (above) for
why it is kind of a guessing game.

So as mental recap: either with your script, some SQL query, that
mysterious rdlogeditcli, but EXTERNALLY to rivendell, you create a macro
cart that (or a set of themor one that calls others... I'm
processing that in my mind) that someway guesses the right LINE, then,
the easy part LL, MN line, PL etc ...


I think you have the basic concept down. Then, it's just a matter of
figuring out the timing. If you can make your way through the Perl
script, you will learn that the timing calculation is likely the most
complex part.

Two aspects I have not included in the time calculation are 1) Cart
Marker settings. I believe the Cart lengths reported by rdclilogedit(1)
come from the LENGTH column in the CUTS table. That does not take into
account "Cut Start", "Cut End" or "Segue Start" Markers, so the actual
times in any given Log (especially near the end of a day) may be off by
as much as several minutes. And 2) multiple Cuts in a Cart: my
understanding is that RDAirplay chooses which Cut to play in a multi-Cut
Cart at the time it plays that Cart in the Log. Maybe the Perl script
can predict which Cut will be played, but I haven't enough familiarity
with the C++ code to make that decision.


~David

Mmmm ... i didn't even though on those aspects... I was simply crashing 
against the very first issue, but now reading that, I realize about 
those other possible things.


Out of my noob-ignorance (we say here 'ignorance is the most daring') I 
think that, all I need is to get the Line ID of some key events in the 
log... since, every of my 'stop sets' starts with a first cart (I think 
it could be an 'ID' or a 'jingle' :-P) that has a Timed/Hard start time 
and a STOPPED transition, that (I guess) can be used to filter out the 
query looking at the database: For instance, in my experiments, the 
following command (requires a defaul/unsecured SQL install and root):


mysql Rivendell -e "SELECT LINE_ID as line, 
sec_to_time(floor(START_TIME/1000)) as time FROM LOG_LINES WHERE 
LOG_NAME = 'TEST-06162021' AND TIME_TYPE = 1 AND START_TIME != 0 AND 
sec_to_time(floor(START_TIME/1000))> NOW() LIMIT 1;"


Gets the very next-in-the-future Hard/Fixed Start time' event in a log 
from NOW() , using the TIME_TYPE field (seems to be 1 for Hard/fixed 
time), returning the Line_ID and scheduled time.


While, with this one, I can get the (in theory, seems to work) the 
closest (both past / future) Hard Time start event:


mysql Rivendell -e "SELECT LINE_ID as line, 
sec_to_time(floor(START_TIME/1000)) as time FROM LOG_LINES WHERE 
LOG_NAME = 'TEST-06162021' AND TIME_TYPE = 1 AND START_TIME != 0 ORDER 
BY ABS(TIMESTAMPDIFF(MINUTE, sec_to_time(floor(START_TIME/1000)), 
NOW())) LIMIT 1;"


I have opened an issue in Github posting a Feature request for a Macro 
that does all this.. being a macro addition, no GUI/Qt related, I don't 
think it being risky/disrupting on existing code... I wonder with 
something like Cue Next or Cue Closest ... LL 1 TEST-X! CN 1! and 
then PL :-)

Yay! Clearly, deep down the rabbit hole!

Hey! thanks for your help!

There may be other ways to solve this, but I'll address your specific
scenario. What you desire is actually kind of complicated in Rivendell.
It is fairly easy to load a Log and make that Log start at
*approximately* the current time of the day, but due to the nature of
RDAirplay playout, it's difficult to make the Log start at the exact
current time.

There has been previous discussion about this on the mailing list
(http://caspian.paravelsystems.com/pipermail/rivendell-dev/2015-November/023621.html),
and the script I have written
(https://github.com/opensourceradio/ram/blob/master/usr/local/bin/load-log-skip-to-current-time)
builds on that discussion and attempts to be more accurate in starting
the Log at the right time of day.

First and foremost... Is very useful to me: it helps me to stop looking
for something that, surprisingly, is not actually possible by the
software itself. I in fact gave-up as I posted for help on the list, and
expended some time experimenting some SQL querying experiments with some
early positive results getting the line_id of either the closest event
in the future respect to query time, the closest both in the future and
in the past, and also both but filtering to only Fixed Time Event (I
someone is interested on the actual SQL SELECT queries let me know...but
I guess that this has been discussed in the past)

I've taken a look at your script (I'm not confident in perl) and I guess
from it you can query rivendell logs from CLI (my ignorance about that
is what lead me to raw SQL querying) ... clirdlogedit? ... where can I
get more info :-o !!!

I Can assume a basic situation where we know RML commands will arrive
BEFORE certain point in the clock... So, In my RDLogManager Clocks, I
have created a few events (lets say 5 event of 1 minute each) AFTER some
clock point (let's set at :00) and another set of 5 1 minute events
AFTER :30.

To state in a slightly different way: you have Clocks containing
five-minute "stop sets" (more radio jargon) at the top of the hour and
at the bottom of the hour, correct?

Noted down the 'stop set' concept :-P

Problems I'm struggling with:

1- Hour problem: If I RML LL the log, no matter the time it is, it will
cue at the first log event (the 00:00 event) even if I do LL at 10:00 in
the morning
> 2- Minute problem: If I RML LL the log at :28, the log will not play
automatically start playing until :30 (using hard-time with STOP
transition)

Or, in other words, what i want is, if I RML the log at 10:28, I want it
to play the set of events scheduled from 10:30 to 10:35

I know I can specify a PL mach ... but, how to know which of the
line to load based on the clock?

Those packages are the official packages provided/builded from the

Until very recently, Only Ubuntu was supported... thanks to Delio from 
AudioScience (maybe he's reading! :-) , his patience with me, and the 
solving of some hardware bugs on ASI 57xx cards (solved from hardware 
rev.G upwards) the package builds the packages on Oficial Debian Stable 
(currently 10/Buster) tool.


The packages are ALSO available from AudioScience's official Ubuntu PPA 
repository... So, I recommend for Ubuntu users to stick with them, as 
they're the official ones, and are regularly updated/maintained directly 
by the manufacturer.


For Debian 10/Buster, those PPA's packages are valid... although mixing 
Debian Repos with Ubuntu PPA's isn't recommended (For instance, I use 
them in Rivendell for my tests, but at Job I use the provided scripts to 
build our own pure Debian DKMS packages, and upload them to our own 
Debian private repo)


Python-audioscience is a package that provides the python API, which 
allows to interface with ASI cards using python (currently, there's a 
bug on that package when installed on Debian).


qasmixer has nothing to do with AudioScience... it is a Debian Packaged 
(and therefore availble on Debian based distros, such Ubuntu) 
lightweight, Qt based, ALSA GUI mixer (ideal in ligtweight/minimalistic 
desktop environments)

Interesting! My understanding has always been that it’s ‘either/or’ as 
well.
Aha... It is fun if, upon having AudioScience ALSA package/driver 
installed (which conflicts whit HPI-only driver package)... You can use 
RDAlsaConfig as it detects and allows you to declare as ALSA useable any 
ASI card (that I have tested) in Rivendell Afterwards, you go to 
RDConfig -> Host -> Audio Resources and ...tada!!! you'll see the card 
twice!!! first as reachable through HPI API, and second through ALSA :-P



so I can use and AudioScience card as Jackd interface (as ALSA 
interface), AND let rivendell detect it as an HPI interface, AND 
enjoy the powerful Audiocience PCM internal routing abilities (I 
think, rivendell does not takes advantage of that, but you can 
harness all that power with any ALSA mixer)…


Rivendell in fact makes extensive use of that ‘anything to anywhere’ 
architecture, but does so *internally*. It most intentionally does 
*not* export the arbitrary capability to the end user, because doing 
so opens up all sorts of opportunities for the user to get the mixer 
subsystem into inconsistent states. For this reason, I would *not* 
recommend using the ALSA capabilities simultaneously with Rivendell,


Cheers!


I think I understand what you're refering to  The thing is that, 
through HPI, the number of Inputs/outputs do match 'only' the number of 
physical Inputs/outputs of the card, which, may or not (In my experience 
usually not) match the number of of actual PCM inputs / outputs 
supported by the card.


For instance, here I'm testing with an ASI5810 and an ASI5720, which 
both feature 4 PCM playbacks and 2 PCM records (although both having 
different number of physical in/out numbers and types), so, from an ALSA 
point of view, both feature 4 playback/outs and 2 record/ins, which can 
be used, and then routed, using the ALSA mixer tomanage the card 
internal router, to/from any of the card's analog/digital physical 
in/outs (Mostly the way Windows users know to use ASI cards through the 
ASI manager GUI)


By contrast, from HPI/Rivendell's point of view, apparently only 
'physical endpoints' seems to matter... So, ASI5810 has 'only' 2 inputs 
/ 1 output , and the ASI5720 fatures 'only' 2 inputs / 2 outputs.


I agree but, that, given Rivendell's perfect integration with Jack, 
providing plenty of in/out, the best approach is to completely forget 
about ALSA PCM<->physical routing stuff and stick to rivendell's native 
HPI support.

A better approach might be to configure Rivendell itself to start the 
jackd(1) instance. See RDAdmin->ManageHosts->[hostname]->JACKSettings. 
That way, your jackd(1) configuration gets saved in the Rivendell 
database and hence will be included as part of the regular backup 
process, plus you eliminate the need to tweak the ‘rivendell.service’ 
unit file each time Rivendell is updated. The primary drawback of this 
approach is that you will need to restart the ‘rivendell’ systemd 
service every time those command-line parameters change. (While this 
is a bit of a bother during the initial system setup, it’s basically a 
non-issue once you’ve settled on the jackd(1) parameters that you want 
to use).


Cheers!


aha... today I will try that!

I didn't before because I'm not sure whether I could set the promiscuois 
environment variable that way, maybe it will get it from 
/etc/environment anyways... or maybe I can set it with an export command 
followed by a semicolon and then, the jackd command... I have to 
experiment... I used a Systmd Unit because, on the uncertainty/novelty 
of the rivendell stuff to me, I tend to stick with what I'm familiar to...


Regards.

With the exception of (some) things related to JACK, it should never
be necessary to restart the rivendell service after making
configuration changes in rdadmin(1). If you find a situation where
that is necessary, please report it as a bug!
I'm aware this isn't the best time to test rivendell, since you're in
the middle of a major version change going qt5 ( that will be a quite a
milestone!), on top of that, I'm also aware that because of my lack of
experience in managing the Rivendell ecosystem, together with the
Debian/CentOS differences, I'm not in a good position to confidently
report on bugs that, often, aren't nothing but simple mistakes.

Today but, I've reproduced the situation where an RML SA on a running
rivendell terminal (Local Audio Adapter switch against the Jack
interface) didn't apply or was silently ignored... and then, after a
rivendell restart, a re-issue of the same RML SA set the crosspoint as
expected.

(maybe for a full caed restart... I'm speculating here)

Restarting the ‘rivendell’ service *does* do a full caed(8) restart.

Yesterday I missed very very much any way to monitor the
crosspoint/switching/routing status of a Switch device (Maybe there's
some way to get it!?!?!)... but I didn't find it. Also, there seems
to be not feed-back upon the RML execution... you throw it, and
that's all... I found myself faithfully believing it was
applied/working... so this part is incredibly hard to troubleshoot.

Agreed. There are some formidable practical obstacles however;
starting with the fact that some of the supported devices —e.g. Grass
Valley GVC 7000 protocol — provide no mechanism for reading the actual
state of the switching matrix. For those devices, Rivendell itself is
in the situation of having to fire off protocol messages in the pious
hope that they actually work, with no means for determining that that
is actually so.

Mmmm... I get the point... I have no experience on those devices, but I
understand what you're depicting is kinda hard situation to handle from
a sysadmin / programmer point of view... hopefully those things feature
some way to check their status on their own.

I'm aware that, although easy to say, implementing even a basic cli
capability of 'status report' on you internal audio routing/switcher
daemon (I guess caed?) would imply rather hard-to-implement features,
such as some kind of volatile or persistent storage on crosspoint
status, levels, etc, etc... all that on a very 'core' part of rivendell,
and not of much help (if any) on those 'autistic' devices.

It would be very nice but (let's dream! :-), in the future, to have some
kind of equivalent to the GPIOMonitor but for the internal audio
routing/crosspoint (caed?) engine

Re: [RDD] rdcatchd and caed crash when not run as root

2021-06-12 Thread Alejandro Olivan Alvarez


HI.

I'm not really an end-user, but more of a 'system-programmer', so I 
don't use default /full-blown desktop environments... so no pulse-audio 
, and jackdbus, well, I guess it is here, but more as a mere dependency 
on modern X11 envs.


My rivendell workstation approach consists of just ALSA (alsa-utils , 
etc.), over a bare-minimum X11 environment using (slim, as display 
manager, and openbox as window manager, and on top of that I add the 
typical compton, nitrogen, tint, etc stuff to taylor a pure/dedicated 
rivendell experience)


Also, recently, re-reading my emails with AudioScience engineer (I 
worked with them for an independent Linux project on my job) I realized 
the AudioScience ALSA driver provides BOTH (and not 'either' as I had on 
my mind) the HPI interface AND the ALSA interface, so I can use and 
AudioScience card as Jackd interface (as ALSA interface), AND let 
rivendell detect it as an HPI interface, AND enjoy the powerful 
Audiocience PCM internal routing abilities (I think, rivendell does not 
takes advantage of that, but you can harness all that power with any 
ALSA mixer)...So, in a nutshell, here's what I'm using (sound-wise):


apt-get install snd-asihpi-dkms-4 python-audioscience alsa-utils qasmixer

Hi!

I've been for several weeks now playing with Rivendell (on Debian) 
too ... and I faced the same thing as you comment.


I have (IMHO) solved all jackd / root/non-root issues in a way that I 
consider the perfect/definitive one: I run jack IN PROMISCUOUS MODE 
(a mode designed, although rarely used by the average user, precisely 
to allow multi/cross-user client/server inter-operation/sharing, 
instead of jackd's default users compartimentalization. In this mode, 
as long as any user is on a given, same, POSIX group, declared as env 
variable by the user terminal starting Jackd, their jack-client 
instances are user-inter-operable with a common/shared jackd 
server... ), so, to my understanding, rivendell setup is a perfect 
use-case for a promiscuous-mode jackd deployment... here's what I do:


- Create a Systemd unit (jackd.service), that launches jackd in 
promiscuous mode for GID XXX (the unit has environment promiscuous 
variable set to GID XXX)


- Where XXX is rivendell group (I also assign statically rivendell 
user UID XXX)


- To further ensure that promiscuous environment variable present 
system wide, I add it to /etc/environment


- I setup jackd.service unit to be run on boot.. so jackd server, 
becomes a system-wide service, reachable to anyone in GID XXX


- I MODIFY rivendell.service systemd unit to be launched/depend on 
jackd.service unit so it is started AFTER jackd.


- I add root as memeber of group rivendell (GID XXX) , so rivendell 
process, owned by root, can connect to jack service


- I add the normal system user that logs in the terminal, to 
rivendell group (GID XXX), allowing him ant his jackd clients to 
connect to jackd service.



This way, the jackd stuff is totally and completelly user 
transparent/traversal ... rivendell connects to jack just as it 
starts, NO NEED to configure anything, it just works.


Logged user starts qjackctl and, tada!...  it connects automatically 
to the already running jackd server (no need to start jackd from 
qjackctl!)


Any jackd-client application launched by the user, appears in the 
patchbay, and can be connected to/from rivendell (run as root, member 
of XXX)... No problems, no issues, no conflicts, everything JUST WORKS



The only little inconvenience here is that, whenever I update 
rivendell, the rivendell systemd unit is reinstalled, and I have to 
modify it again to make it to 'want' jackd.service.



Hope this helps... If someone is interested on further details on how 
to do this, just let me know!


Best regards.

Re: [RDD] rdcatchd and caed crash when not run as root

2021-06-12 Thread Alejandro Olivan Alvarez

Hi!... OK... I'll do my best to keep this as concise as possible...if 
necessary, we could go deeper afterwards if needed-


Starting at some Ubuntu (I'm using Debian) install instructions I 
initially used as reference, lets consider rivendell system user is 
'rivendell' , with UID/GID 150 I will create a X11 regular 
system/pam user 'operator' that will use the rivendell terminal:


- 1st:

adduser --uid 150 --system --group --home=/var/snd rivendell
chgrp rivendell /var/snd
chmod g+w /var/snd

- and:

useradd -m -g rivendell -s /bin/bash -p $(openssl passwd -crypt 
VERYSECRET) operator

adduser operator audio
adduser operator dialout
adduser operator sudo


- At this point, I'm doing something that I think is not necessary, I've 
still not tested/confirmed this point, but I'm not 'fine tuning' 
Rivendell install at this point (I'm just learning how to use it at its 
very limits/capabilities). Essentially I will setup, system-wide, the 
necessary environment variable to ensure that, any terminal, virtual or 
interactive, spawned by any user, belonging to GID 150 (rivendell) will 
'participate' on the promiscuous Jackd 'party':


echo "JACK_PROMISCUOUS_SERVER=150" >> /etc/environment


- Now I will setup a systemd unit that will take care of providen a 
system service consisting on a 'root-driven-but-GID150-promiscuous' 
jackd instance. **NOTICE my unit is commented/templated so jackd can be 
setup against either a dummy card, or to a real ALSA interface. For the 
sake of example, I've let the card-independant dummy one, so a cut/paste 
of this unit will work.


Here's the contents of /etc/systemd/system/jackd.service

[Unit]
Description=Start the JACK server in promiscuous mode for GID 150
After=sound.target
StartLimitBurst=5
StartLimitIntervalSec=33

Type=simple
Environment="JACK_PROMISCUOUS_SERVER=150"

# For ALSA device binding running mode:

# For a floating/independent jackd running mode:
ExecStart=/usr/bin/jackd -R --name default -d dummy -r 48000 -C 2 -P 2
Restart=always
RestartSec=5

[Install]
WantedBy=multi-user.target


- At this point, I have to tweak the rivendell Unit:

It must have to be launched wit proper Environment variable to it joins 
the promiscuous Jackd party.


sed -i '/^Type=.*/a Environment="JACK_PROMISCUOUS_SERVER=150"' 
/lib/systemd/system/rivendell.service



I want it to start after the jackd.service **NOTE: this last part, I 
think, can be further enhanced, I've not tested enough, but I think a 
bether systemd units inter-dependency can be achieved than just 'After' .


sed -i -e '/After/s/$/ jackd.service/' /lib/systemd/system/rivendell.service


- Finally, reload systemd and enable those services:

systemctl daemon-reload
systemctl enable jackd.service
systemctl enable rivendell.service


At this point, upon reboot, user 'operator' logs in, and launches 
qjackctl...what SHOULD happen:


- qjackctl instantly recognices and binds to the system-wide, 
already-running jackd instance.. NO NEED to start jack


- In patchbay/connections, rivendell should appear (connected to jack) 
and, although ran by root, its inputs /outputs connections can be freely 
managed


- Any rivendell restart, will result in instantaneous jackd 
re-connecting to the system-wide jackd.


- Any jack client application launched by 'operator' binds to jackd 
(jamin, glassplayer, glasscoder, linphone...) and, even being run by 
'operador', its in/outs can be freely connected/disconnected to/from 
rivendell


- Therefore, a patchbay config can be setup and enabled in qjackctl, 
100% GUI, to automate connections, no need to program/script jackd 
connections, the user is free to operate the thing on his own.


- The user can use Jacktrip GUI to send audio in/from rivendell 
instances, in separate workstations, over LAN/WAN very easily



Hope this works on other systems as does in my Debian Buster/Stable 
experiments... but it may be helpful anyways... also, as I mentioned, 
I'm aware all this could be further enhanced/fine-tuned


Best regards.

2021-06-11 Thread Alejandro olivan Alvarez


Hi

Although I'm a devoted Debianist... I think I could suggest a solution 
somehow platform independent (although installation of required packaged 
software varies, obviously) that I use and I'm very happy with: I get 
rid of direct VNC connections and I setup VNC over HTTP ... in other 
words, I setup the system in a way that the X11 terminal is accessed 
with any web browser (as long as you know the terminal IP/hostname)


The two parts of the solution imply the combination of two pieces of 
software, x11vnc and python-websockify (the Debian package includes a 
nice VNC javascript client ready-to use... a piece of cake)


I simply setup a pair of systemd units that, upon start:

- Create a x11vnc server connected to the display

- Launches websockify, connects to x11vnc instance, and serves the VNC 
javascript client on port 8080


then, on any browser: http://myrivendell-terminal:8080 ... done!


If someone is interested on further details... just let me know.

Best regards.

Re: [RDD] Howto 'Legal copy' 'logger' continous recording...

2021-05-31 Thread Alejandro olivan Alvarez


Thank you all for the feedback!

So, in a nutshell, Rivendell is not meant to do that... it is meant (for 
understandable arguments) to rely on an external/independent recording 
solution (ffmpeg, rotter, whatever...)


Independently of that, nothing prevents externally recorded materials to 
be ingested in RDLibrary for availability of such materials... 
Considering that a Cart can hold 999 cuts, It wouldn't be hard to setup 
12 Dropbox/cart combos, that you can use toghether with rdimport to 
ingest hourly records into... once knowing the 'external way' is the way 
to go that's not a problem at all.


It would but, in my opinion, a nice feature to have (having the

It can, but not particularly easily. My own take on this has always 
been that the classic ‘audio logger’ is out-of-scope for Rivendell; 
the principal reason being that the primary purpose of a ‘logger’ is 
to keep track of some particular process (in this case, proper on-air 
play-out) so as to provide useful data for tracking down anomalies. 
That being the case, the logger should ideally reside in an entirely 
separate and independent system from the one being logged, otherwise 
anomalies in the logged system will tend to contaminate the data 
captured in the integrated logger as well.

[RDD] Help setting feeds in RDCastManager

2021-05-26 Thread Alejandro olivan Alvarez


Hi list!

I'm failing to setup an RSS feed in RDCastManager... Long history short: 
the form fails to submit showing a pop-up window stating: 'XML data 
upload failed!'


Syslog shows that rdexport.cgi script is being executed, but, as some 
point, something goes wrong... Here's its stdout to syslog:


May 26 18:17:34 debian rdxport.cgi: processing RDXPORT_COMMAND_POST_RSS
May 26 18:17:34 debian rdxport.cgi: posted RSS XML to 
"file://home/operador/test1.rss"

May 26 18:17:34 debian rdxport.cgi:  'podcasts.cpp' line 472

Online documentation seems too old... I readed PODCASTING.txt file, but 
still, I still don't fully understand how the podcast 'bussiness logic' 
works under the hood, I'm not sure on how to debug things here... I'm 
stuck in this one.


At first I blamed on the usage of fake HTTP and FTP URLs (maybe the code 
checking the validity/availability/connectivity of the URLs), so I 
cloned a mockup Apache2/proftp VM to have true ftp/web services up, 
right ftp creds and so on... but it didn't help... Now I'm just trying 
the file:// protocol as a safe way... still, no changes... I feel it is 
something more essential/basic that I'm really missing.


I've looked at the podcasts.cpp code , line, 472... but it is just the 
line that prompts exiting...so no clue beyond that, and that line 421 
was executed, but, at some point 'ret' was or became null/void


What could be happening here? Any clue on which fields are mandatory? 
what conditions could trigger that error?



Thank you very much in advance.

Best regards.

Re: [RDD] Using Audacity On Rivendell Computer

2021-05-26 Thread Alejandro olivan Alvarez


Hi again.

You can, and you can not... I'll try to explain:

(At least in Debian world, and AFAIK) AudioScience cards can operate in 
two mutually exclusive modes:


1. An AudioScience 'native' audio engine mode, driven by its proprietary 
'libHPI' kernel module: In this mode, only applications programmed and 
compiled with AudioScience libHPI library can use the ASI sound card 
(Rivendell is such a program) directly, independently of any Linux audio 
engines such as ALSA.


2. ALSA audio engine mode. In this mode, the card loads a driver that 
makes it to work with the Linux 'normal' audio engine (ALSA here) ... 
becoming a normal sound card, and, therefore, any audio application will 
work. Notice that, Even in this ALSA mode, if you declare the card as 
managed by Rivendell (something you could do, as you can use any ALSA 
sound card with Rivendell, using RDAlsaConfig GUI program) in order to 
use it will  'take control' of it, making it unusable for other programs 
(or at least, conflicting)


I do not know for CentOS (I use Debian) , but for Debian, only one of 
the AudioScince kernel module packages (either ALSA or libHPI ) can be 
present/installed on a given computer. My guess is that, being something 
kernel related (The actual audio card will load a different firmware 
depending on which mode will it work upon booting) this limitation will 
apply to CenOS too... You may need a dedicated, separated, 'production' 
machine, even connected to Rivendell.


Best regards!

So, any ideas on how to get the ASI card working with Audacity without

Re: [RDD] Growing the Rivendell system

2021-05-26 Thread Alejandro olivan Alvarez


Hi!

I recently tested (and even had some issues that learnt hot to overcome) 
exactly what you're trying to do... I will try (I'm not an experienced 
Rivendell user, but quite an experienced Linux administration 
professional) give you the clues to achieve what you're looking for .


Rivendell has a pair of 'modules' (GUI programs) that do what you want 
to do: RDSelect and RDMonitor ... so, here you can start googling on 
them, but, in a nutshell, RDSelect is a GUI 'switching' program that 
allows you to 'switch' your database/storage combo target, so, yo can 
switch from 'local' to 'remote', or 'master' to 'backup1' or 'backup1' 
etc...


RDMonitor is a small floating app which tells you to which 
database/target combo are you currently connected to, and whether or not 
connection to the selected 'server' is successfull.


The key for this to work is to switch from a default installation where 
you have a unique/single config file: /etc/rd.conf to a setup where you 
create a folder named /etc/rivendell.d where you can have as many 
'switcheable/selectable' configurations as you want/need , for instance, 
/etc/rivendell.d/local-backup.conf and 
/etc/rivendell.d/remote-master.conf . In that scenario /etc/rd.conf 
becomes a soft link that switches to the selected/active 
/etc/rivendell.d/x.conf as requested.


Rivendell will 'detect' the presence on /etc/rivendell.d folder of 
.conf files (rd.conf files), and RDSelect will automate the 
deletion/creation of an appropriate soft-link to /etc/rd.conf along with 
services restarting when you 'switch' from config to config.


At this point, all you have to configure is, on every conf file within 
rivendell.d, the connection details to the database (that's where 
database connection details will differ from config to config, depending 
on wether the config is intended to target a remote database or a local 
database) and the filesystem mounting details into /var/snd... The parts 
of the .conf files that you have to 'play with' are the [mySQL] and 
[AudioStore] sections.


The mySQL one was quite straightforward, the AudioStore one was a little 
more obscure to me: being a Debianist, I had to figure out that the 
storage switching process was handled through autofs (so I had to 
install it on Debian) but, from that point on, It was a matter of a 
little googling abut it (I had some issues, but got help on the list :-)


Regarding your storage backup concerns... My advice as a Linux admin is 
to separate backup from High-availability concepts... both are 
necessary, but not the same... For example, I use as storage scenario a 
pair of DRBD + Keepalived clustered/HA servers for NFS storage, so I can 
survive loss of one server, while 'backup' is done with rsync to an 
external NAS. While for DB I use a MariaDB, three-node galera cluster 
for HA, so I can loss one server, while for backups I rsync sqldumps 
regularly to the external NAS.



Hope I helped clarifying the picture... Best regards!

Currently using CentOS7 and Rivendell 3.5. I have two computers 
essentially the same. They are both on the same network. I need to 
join them for a common audio library and database. I do want to have a

Is there any document for setting up the client/server stuff? Like

Very clever approach! ... How did i miss that!

That way, since you're setting a fs type on the config for autofs... It
will just work!
I'm thinking that adding lvm2 to the picture, could keep also some
partitioning flexibility in that scenario... Have to try that!

Thank you very much for your advice!

Really!?!?!

hope this could be confirmed for current versions... since, toghether 
with the rdselect config/hot-switching feature 
(/etc/rivendell.d/x.conf) it would be a very very interesting and 
potentially usefull feature (I'm thinking, for instance, on a 
training/learning terminal).


Although the rdselect/autofs mount switching works perfect for NFS, it 
really doesn't (or I failed to make it to work) for local filesystems... 
As of now, If I would like to have a multiple local filesystem and 
switch between them, I would have to setup nfs-kernel-server and do 
localhost export/mount to /var/snd

Re: [RDD] Re-Importing a cut after external edit

2021-05-19 Thread Alejandro olivan Alvarez

Ah wow! really?!  I'm not exactly sure on the procedure you 
commented but have to try this out!


In my early experiments, opening the acual cut under /var/snd through 
external editor and saving (overwriting) screwed the cut... Since I saw 
a hash field on every cut, my guess is that, sure, upon modifying the 
cut, the hash mismatches, and we got an ugly inconsistency.


So, now, your suggested path is:

1 - copy the original file out from /var/snd to a temporary location ...OK

2 - Then, open the copy, not the original, on the editor for work 
although, upon ending edit work, you replace the original file with the 
edited copy ... OK (although I fail to understand the difference on 
editing the original file directly)


3 - Now (I guess, with a screwed cut shown on RDLibrary) I just ignore 
anything about this cut and go directly to open the Edit Markers utility 
on it... there, either do nothing or, if needed, adjust the markers... 
Save... Tada! rivendell automagically refresh/rehash the cut out of the 
exiting (altered/edited) file


Isn't it?

Thank you very much for your help.

Regards.

I have found that re-importing a file is somewhat destructive and 
compromises quality slightly, whereas with our method, there is only 
the loss that is instituted by the external editor.

Hi list.
I'm trying to add some enhanced external edit usability to my rivendell
mockup, by scripting somehow, what I know other systems do upon external
editing: Copy the actual audio to a temporary file, open the temporary
file in the editor and, upon returning from file edition, check whether
the file was actually modified and, if so, re-import/overwrite the
currently existing material (cart/cut here).
The concept in my tests involves audacity and rdimport... I would call
the script as the external editor, passing %f, and execute my logic
there... thats the easy part.
The problem is that , whenever I try to use rdimport , I'm facing a
GROUP issue: rdimport complains no group or bad group... but I don't
need/want any group change, just re-import.
How could I re-import the edited file to the same cart_cut? I don't find
in wiki or in man a prpper way to do what I want... Why do I need a
Group at all when I specify an existing cart? ... if the cart and cut
does exist, it belongs to some Group on DB ... Another approach is to
guess the group, but, how could I guess the target group out of the
cart/cut? (sure querying the DB, but that's overkill!), does the

Re: [RDD] Alternative /var/snd directory

2021-05-19 Thread Alejandro olivan Alvarez


Hi.

I'm also learning Rivendell in the latests weeks... mostly playing with 
VMs... very successfully.


To may knowledge (still limited) /var/snd is quite 'hardcoded'... but, 
from a Linux Administration point of view, it is fairly easy to mount on 
/var/snd whatever remote or local filesystem you want:


For remote, I use NFS with no problems... I guess you could use CIFS (I 
have not tested though) or whatever indeed trasparently to Rivendell... 
but consider that you could do, in theory, do a BIND mount of another 
folder into /var/snd (check BIND mounting). I have but had problems 
using bind mounts while trying to setup multiple rivendell setups on a 
single machine (using rdselect/rdmonitor combo) since I'm not succeeding 
on making autofs to bind mount a local folder into /var/snd... Another 
approach I'm thinking of (also untested) is to just use a Soft/Hard link 
against the desired FS place... maybe its as simple as that.


From your info, I guess your best bet is to figure out what's 
preventing your VM to mount your remote NFS 3TB storage, because from 
waht you said, it wasn't really mounted (writes went to local 
filesystem)... probably some kind of firewalling or routing issue 
between your VM and the storage server is preventing the mount.


Best regards.

[RDD] RDSelect rd.conf storage mount issues.

2021-05-17 Thread Alejandro olivan Alvarez


Hi list.

I'm making progress exploring Rivendell's features... but I'm stuck on 
RDSelect.


Initially I got segfaults, apparently due to SQL issues... but I'm not 
sure wehter they were totally unrelated (I missed the RDMONITOR.txt file 
where it explains the necessity of a linked rd.conf file, and the Label 
entry in rd.conf to differentiate/label difefrent setups).


Now RDSelect starts (needs root) but the switching between 
configurations do fail at storage level: I see no mount for the 
specified mounts:



For the sake of example, I have the following fstab (working 
individually, but commented so they don't conflict targetting /var/snd):


#192.168.1.2:/exports/snd    /var/snd    nfs 
_netdev,x-systemd.after=network-online.target,rw,auto,rsize=8192,wsize=8192,timeo=14 
0    0

#/home/operador/snd    /var/snd    none    bind    0    0

Now, on each of my rd.conf files under /etc/rivendell.d, local.conf and 
remote.conf y set the Audiostore sections


[AudioStore]
MountSource=/home/operador/snd
MountType=none
MountOptions=bind
CaeHostname=
XportHostname=


and

[AudioStore]
MountSource=192.168.1.2:/exports/snd
MountType=nfs
MountOptions=_netdev,x-systemd.after=network-online.target,rw,auto,rsize=8192,wsize=8192,timeo=14
CaeHostname=

Upon switching, the link to /etc/rd.conf correctly switches, rivendell 
is restarted, and database cbinding to either remote or local database 
is satablished...so far, so good.


But no mounting of remote filesystem is performed sure I'm missing 
some detail somewhere!


Could someone help?


Thank you very much in advance.

Best regards.

Re: [RDD] Local Audio Adapter GPIO: serial not active

2021-05-06 Thread Alejandro olivan Alvarez


I'm starting to feel maybe something is wrong here...

Looking just at the GPIO form, upon trying to add a Local Audio Adapter 
GPIO driver matrix, I realized that although correctly greyed out), on 
the Primary Connection section, 'Type' field, has the value: 'Serial'... 
while on Backup Connection section, field 'Type' is (I guess correctly), 
the value 'none' why the difference?, shouldn't both to be 'None' ?


My guess is that, If first field 'Type' (the 'primary') althoud 
disabled, is hardcoded to 'Serial', then, I guess, the following line of 
code: (line 1194 at edit_matrix.cpp): 
switch((RDMatrix::PortType)edit_porttype_box->currentItem()) { Gets 
value as a serial, instead on none...  and teherefore, line 1203, case 
RDMatrix::TtyPort: matches instead of 1214 case RDMatrix::NoPort: ... 
and then the error rises.


I have to dig further on from where do those default form values come 
from, they may be wrong for Local Audio Adapter...

Re: [RDD] Local Audio Adapter GPIO: serial not active

2021-05-06 Thread Alejandro olivan Alvarez

Hi again list...

Since I digged and researched quite a lot about rivendell before messing
with it, I had in my mind that I read somewhere in rivendell stuff about
what I'm trying actually to do and I'm failing to ... Since now I have
found the original document (Rivendell wiki!) here i put the URL to the
document, so that may give a context on what I'm doing wrong:

http://wiki.rivendellaudio.org/index.php/How_do_I_make_Rivendell_play_Audio_from_the_%22Line_In%22_of_the_Sound_Card_on_the_air%3F

Specifically, the issue comes as I try to follow the advice stated there:

Configure a switcher using the 'local audio' device (rdadmin->manage
hosts ->switchers/gpio), then the standard switcher commands can be used
to switch to and away from the sat. feed. The best thing to do is
probably to use a macro cart to switch and stop the main log at the
appropriate time (fire it from rdcatch so you have gpi signals available).

"Local audio device" is Rivendell switcherese for a local soundcard, you
configure it to function as a switcher just like an external one, but
done in software.

Basically, a standard rivendell soundcard has inputs feeding a routing
matrix with the outputs from the matrix summed with the output ports
from the playback engine (Either in hardware, with ASI cards or in
software within caed), when you define a matrix as being a "Local audio"
that routing matrix becomes available as a switcher device to rivendell.

The problem is that, no matter what, I get the "serial device not
active!" error.

maybe a caed problem?

Thanks, regards

Thank you very much in advance.

My first guess is this is a permissions problem.

On my systems "ls -l /dev/ttyS0" looks like this:

crw-rw. 1 root dialout 4, 64 Apr 9 15:54 /dev/ttyS0

And I know that neither Linux user "rd", nor "rivendell" are in the
"dialout" group. Try this:

sudo usermod -a -G dialout rd

Then log out and back in (or reboot). Please report back if this helps.

[RDD] Rivendell Virtual Machine

2021-05-06 Thread Alejandro olivan Alvarez


Hi list.

I'm new to rivendell, but I have some years of experience in cloud 
computing and virtualization.


I'm using rivendell VMs (although everything just mockup/tests for 
learning) very successfully (to the moment) toghether wit physical 
rivendell PC, in a mixed physical / virtual mockup (I use PROXMOX for 
virtualization)... To 'move'/'share' audio between hosts my advice is to 
check JackTrip: https://github.com/jacktrip/jacktrip


It is meant (although not mandatory) to do exactly that, far, far easier 
than NetJack stuff  It is a 'normal' jackd server client application 
that allows to move audio very very easily between other jackd hosts, 
both over LAN, but also over WAN (with its logical limitations).


If you prefer GUI, check a branch on the repository called qjacktrip 
(still in development, but very much useable to my taste) which provides 
a nice GUI Qt application to handle jacktrip from the desktop.


As of Debian (I'm debianist) Buster, jacktrip packaged release is quite 
old and not much functional to my taste ( Bullseye/testing includes 
quite a recent 1.3.0 version)... So I have created a .deb package that 
provide both latest jacktrip and qjacktrip for debian 10 Buster if 
someone's interested.


Best regards.

[RDD] Local Audio Adapter GPIO: serial not active

Hi. Thank you for your help.

I don't know enough about the rivendell ecosystem to guess whether its 
system-side issue (permissions a good candidate) or some Database issue 
(bug)


System side, with the exception pf the pypad daemon, it looks to me 
everything is 'root' driven:


root@rd-terminal-alex:~# ps aux | grep sbin/rd
root   489  3.9  0.7 211456 27884 ?    Ssl  18:07   2:32 
/usr/sbin/rdservice
root   586  4.9  2.7 211824 103120 ?   SL   18:07   3:11 
/usr/sbin/rdcatchd
root   587  0.0  0.6 136524 24948 ?    S    18:07   0:00 
/usr/sbin/rdpadd
pypad  588  4.1  0.7 211196 26376 ?    S    18:07   2:41 
/usr/sbin/rdpadengined
root   589  4.9  0.9 218348 36488 ?    S    18:07   3:11 
/usr/sbin/rdvairplayd
root   693  0.0  0.0   6208   888 pts/0    S+   19:12   0:00 grep 
sbin/rd


Anyways, I checked the existence of the ttyS0 device (although I don't 
understand why is it checked for a Sound Card based GPIO) and dialout perms:



root@rd-terminal-alex:~# ls -l /dev/ttyS0
crw-rw 1 root dialout 4, 64 May  5 18:07 /dev/ttyS0

root@rd-terminal-alex:~# cat /etc/group | grep dialout
dialout:x:20:operador,rivendell


Both look good  in the meantime, I investigated a little the source 
code and checked the Database table:


MariaDB [Rivendell]> select * FROM TTYS;
++-++--++---+---+---++-+
| ID | PORT_ID | ACTIVE | STATION_NAME | PORT   | BAUD_RATE | 
DATA_BITS | STOP_BITS | PARITY | TERMINATION |

++-++--++---+---+---++-+
|  1 |   0 | Y  | rd-terminal-alex | /dev/ttyS0 | 115200 
| 8 | 1 |  0 |   0 |
|  4 |   1 | N  | rd-terminal-alex | /dev/ttyS1 | 9600 | 
8 | 1 |  0 |   0 |
|  7 |   2 | N  | rd-terminal-alex | /dev/ttyS2 | 9600 | 
8 | 1 |  0 |   0 |
| 10 |   3 | N  | rd-terminal-alex | /dev/ttyS3 | 9600 | 
8 | 1 |  0 |   0 |
| 13 |   4 | N  | rd-terminal-alex |    | 9600 | 
8 | 1 |  0 |   0 |

++-++--++---+---+---++-+
6 rows in set (0.000 sec)

So the TTYs are there...  and, if I tick the checkbox to enable the 
serial port, the ACTIVE field switches Y/N.


Apparently the problem comes as rdedit_matrix.cpp seems to call Active() 
function of rdtty.cpp , I'm not sure about this...I digged just a little 
bit more there and ended at GetStringValue(const QString ) 
function, which queries de database like this:


MariaDB [Rivendell]> select ACTIVE from TTYS where 
STATION_NAME="rd-terminal-alex"&_ID=0;

++
| ACTIVE |
++
| Y  |
++
1 row in set (0.000 sec)


If the first Active() call fails, then the QMessageBox with the "The 
primary serial device is not active!" string is triggered , which I 
think is what I'm seeing (not really sure, but I bet is this)... why 
does Active() fails? I don't know ... hopefully I'm missing some obvious 
system-side detail.



Thank you very very much for your help!

Best regards!
