[RDD] OT Open OB

[Lee Baker]

Hi All, I know this is off topic but thought it may be of interest to some
you.

 

I came across this https://github.com/JamesHarrison/openob through a
colleague of mine who used this at their community radio station here in aus
for their OBs.

 

It's an open source STL basically which used the Opus codec and works very
reliably.

 

Has many uses and for those looking to build an STL on the cheap, this is
for you.

 

Cheers

Re: [RDD] Documentation on implementing GPIOs?

[Brian]

True.  It would take more work, as I'd have to find the relevant source
code within Rivendell, and figure out what it does, rather than reading the
specification.  Also, my implementation may not end up being fully
compliant with the protocol, and it would be hard to say whether it would
work reliably on any other systems.  If I'm going to implement LiveWire for
GPIO, I want to do it right.

Re: [RDD] Documentation on implementing GPIOs?

[Karl Koscher]

Well, since Rivendell is open source, you can learn enough about the Axia
protocol to make something that interoperates with Rivendell.

this is a script I use to dump a file for each of my 'out stations' from
the central server. it runs at :45 as a cron job

The remotes are "Wireless" "Thames" and "Whangamata"

Data for all services is kept in the central server. This is a belt and
braces update. Seperately each remote service pulls down their weather
and other local items as an mp3 file from the same server.

The updates complete by :52 and locally stations pull down news and
other items which they load from :55 to :59, updating their local
version of mysql 

Some programmes are loaded in the central server for all stations and
the audio gets networked as mp3 and loaded locally because updating wav
files is a bit data intensive. All music updates are distributed at 1am
which works because we typically add only a few tracks each week.

this is the server script

#! /bin/bash
# get tables related to individual services and put them in dropbox
mysql -u root Rivendell -e 'show tables like "%ireless%" ' -s
--skip-column-names | xargs mysqldump Rivendell -u root
>/home/rd/dropbox/wireless.sql
mysql -u root Rivendell -e 'show tables like "%hangamata%" ' -s
--skip-column-names | xargs mysqldump Rivendell -u root
>/home/rd/dropbox/whangamata.sql
mysql -u root Rivendell -e 'show tables like "%hames%" ' -s
--skip-column-names | xargs mysqldump Rivendell -u root
>/home/rd/dropbox/thames.sql
#get tables all services need to update and put them in dropbox
mysqldump -u root Rivendell --lock-tables=false AUDIO_PERMS CART
CLOCK_PERMS CLOCKS CUTS EVENT_PERMS EVENTS GROUPS SCHED_CODES
SERVICE_PERMS SERVICES LOGS>/home/rd/dropbox/hourly.sql
exit 0



at the remote station

we rsync the station.sql and hourly.sql into a local folder from the
central server 

mysql -u root Rivendell /home/rd/dropbox/hourly.sql
mysql -u root Rivendell /home/rd/dropbox/station.sql


I could have made it smarter and tidier, but this transports the
essential changes in small text files that move fast and are 100%
accurate.

mysql makes this kind of thing possible, and enables Rivendell to
function as it does. 

Well worth making friends with! I got a mysql for dummies book and while
I think I am just a novice I have learnt to do stuff with it. Very
powerful tool.

It basically would be Arduino based, just on a board that is more
purpose-made, and without some of the extra stuff on the Arduino.

But you raise a good point... may as well just use an Arduino directly and
save the time and trouble unless this project would bring something new and
novel.

As for ethernet, Yes I certainly could do that.  Along the same lines,
probably simplest to just use an Arduino Ethernet.  But the question of how
to interface still remains.  Need documentation for the relevant protocols
etc to interface with Rivendell.

The one minor annoyance is that Arduino Ethernet units don't have proper
MAC addresses.  You have to supply or derive one on your own.  And if I
recall, the DHCP implementation isn't particularly reliable or robust.

Probably best to look at the RasPi or a BeagleBone instead at this point,
as they're cheaper than the Arduino Ethernet anyway.

The only thing I can think of that would actually make a project like this
worthwhile, after further consideration, is if it can yield a trouble free,
almost zero-setup, appliance-type box that interfaces super easily with
Rivendell, requires no maintenance, and is in an extra-convenient form
factor (1U Rackmount?)

Nevertheless, I'm still curious about how to interface with Rivendell's
GPIO support, if nothing else than for tinkering with hardware, learning,
and getting something working.

[RDD] Voicetracking over a slow connection - what works

[Jim Stewart]

My dream setup would be to use Jack Audio's "Netjack" over the Internet using 
the new Opus Codec so to have very low latency pre and post cut audio 
transported near-real-time to the remote site during voice tracking, then a 
simple rsync script that moves the recorded audio back to the main Rivendell 
library.  Anyone want to tackle this?  The most I got working was the older 
"CELT" codec working with Jack audio over the Internet about a year ago, but it 
wasn't as reliable as I had hoped, but probably good enough for voice tracking. 
 There might also be a problem (for us anyway) as it looks like Opus currently 
doesn't not support the 44.1kbs  sample rate that we have all of our library 
and have our Jack Audio running at. But maybe this would be a simple patch to 
fix?  I would hate to have to resample.

As far as the database issues, I have had good success (despite warnings in the 
Rivendell documentation saying otherwise) using the RML command to snapshot the 
database at about 1:30am then rsyncing it off to the remote site so that it is 
somewhat current for the next morning's use.  It would be nice to know how to 
"restore" the database via an automatic script at the remote end (been using 
rdadmin manually).  Perhaps I can use a mysql restore command of some sort?  I 
don't know mysql at all, have had issue with it, am afraid of it, and finally 
consider it Rivendell's worst attribute.

[RDD] Documentation on implementing GPIOs?

[Jim Stewart]

If could also use an audio switcher (which can also be nicely controlled by 
Rivendell), I've been using the GPIOs from a Broadcast Tools ACS 8.2 (8 input 
by 2 output audio switcher) that also has 16 GPIs and GPOs plus a Silence 
Sensor that interacts with Rivendell nicely.  I've been using it all with good 
success.  I have a remote broadcast setup using a Telos Z/IP-One that also can 
transmit GPIOs across an Internet link and have it set up to do functions like 
"Go live after next event", "Return to Automation", that also turns on tally 
LED's at the remote site that say things like "You will go live next" and "you 
ARE live on the air".  It all works very well except for my recent buggy macro 
issues I reported about a couple of weeks ago, but none of that seems to be 
related to GPIOs, just timing bugs in Rivendell.

So the switcher is about $1000 USD, but since they have been made for a long 
time, they (or their earlier version "SS-8.2") are seen out on the used market 
from time to time too.  For us it been a "one box, does lots of nice things" 
solution.  http://www.broadcasttools.com/view_product.php?pid=145

For those who are still wanting to roll your own, I would think it would be 
nice if it could use the Axia protocol that seems to be somewhat integrated 
into Rivendell, as once you master that you could also control lots of other 
Axia compatible products too.  I don't know much of this as in if you need some 
sort of Axia master device to make it all work or not.

Hi,

I don't have anything to show, it was just a board I have that I play 
with from time to time.  I'm currently turning it into a 1U IP audio

The main thing to remember is the pi is only 3.3v so be careful of the

Pi + PSU + SD Card would set you back about £35 so not too expensive

Nice idea, and if you have a spare serial or parallel port you don't even
need a pi just adjust the script to change one of the control ports.

Re: [RDD] Documentation on implementing GPIOs?

[Lee Baker]

Tis true Cowboy,

All of my machines, bar my main desktop have serial on them and parallel
ports.

I just want to fire off from the fader channel on the panel.

Just reading how the Pi GPIOs are laid out, assuming it would just be a
matter of wiring the fader chanel nc wires to ground and a gpio then program
riv to pick it up.

Does riv support the GPIOs on the pi? Of course it wouldn't be much use for
anything else due to it's lack of oomph...

 Does anyone still make a machine with a serial port ?

 It seems to me that IP would be best, and clearly the  most universal, with
USB a reasonably close second,  but serial is as obsolete as is the parallel
port.

 Does anyone still make a machine with a serial port ?

Re: [RDD] Documentation on implementing GPIOs?

Hi Wayne,

 

I have a Pi and had thought to use its GPIOs but wasn’t sure of how to do
it.

 

How have you set yours up?

Hi all,

Coming from a completely different angle I've been toying with using a Pi's
GPIO pins and rmlsend to interface to Riv.

Pi + PSU + SD Card would set you back about £35 so not too expensive either.
Something to think about.

Hi Brian,

 

Your project sound interesting. I’d certainly be interested.

 

I am in need of an interface so that I can remote fire from mixing console.

 

Have tried using an old soundcard with midi port and making a joystick plug
to no avail, have also tried finding info on using the serial port but this
is hard as there is very little documentation.

 

Good luck :)

I'm thinking of making my own GPIO interface for Rivendell, custom circuit
board, etc., based on an Atmel Microcontroller.

 

The simplest way for me to interface it with the system would probably be
RS-232.

 

I can program the chip to speak any arbitrary protocol.

 

Where should I look to find out how to interface with Rivendell's GPIO
support?

 

And if I make these things, would anyone else here be interested in one?
I'm not looking to sell them commercially, but it's always fun to share your
creations with others who might benefit from them, and help offset the
costs.

Re: [RDD] Documentation on implementing GPIOs?

[Marc Steele]

Weirdly, that's a setup we've been using until recently. We had a Pi
controlling a four pole relay over a Mixpak input to do some dumb satellite
switching for news. Rivendell sent commands over UDP to a short script we
knocked together that turned the output on/off. Details at
http://broadcastingtechnology.wordpress.com/2013/08/06/irn-switching-the-weird-way/if
you're really bored.

It's entirely workable but you do need a nice way of sending the data back
to Rivendell for the input side of things. I'd also assume if you're
wanting a GPIO box, you would need to either simulate a supported box or
write a plugin for Rivendell.

Marc Steele.
