[mythtv-users] OS X, MythTV 0.18.1, watch LiveTV crash

[Robert Karaffa]

hi folks,
	my KnoppMyth backend runs beautifully, although I see "stealing a 
buffer" errors about once every 10 days or so.  Haven't pinned-down the 
prob yet.

having said that, my two frontends are:
-KnoppMyth Dell Latitude laptop
-Mac G4 TiBook

The Dell almost never needs any attention.  It just works.
The Mac...well, sometimes it will let me watch TV, sometimes it won't.

When it works, it works great.  Watching Live TV is really not my 
intended use of MythTV, because I mostly watch videos and listen to 
music (heck, I don't even record any TV shows).  However, there are 
times when I have guests who will want to watch Live TV...and yes, that 
does suck.  I HATE Live TV.  Did I mention that it sucks?


The Mac version of Myth that I use is 0.18.1.
I thought I had figured out why it would crash when attempting to start 
watching Live TV (trashing the theme cache folder in ~./mythtv...but 
apparently that's not the cure).


Is anybody working on MythonMacOSX?  I've not seen any posts on it 
lately...that would be a bummer.

[mythtv-users] Re: Playing image(.iso) file in Mythvideo

[Robert Karaffa]

the problem I found with mplayer and xine is that neither would show 
subtitles.  mplayer just flatly refused to do so even when following 
the instructions to the letter, and xine would just lockup X.  VLC, 
however, worked without much trouble at all.  The hardest part of using 
VLC was learning what the command line statement should be so that it 
would quit after playback.  Once properly configured, it beats the 
others like a drum!

[mythtv-users] Re: Playing image(.iso) file in Mythvideo

[Robert Karaffa]

I've been using VLC in lieu of Xine for video playback.  The command in 
MythVideo is:


vlc %s vlc:quit

This plays all video formats I've thrown at it:  .avi, .mpg, .iso, .vob.

VLC is highly configurable, and in my opinion is a better playback app 
than anything else I've seen (I've tried xine, mplayer and the Myth 
internal player...none come close).


I've included my vlcrc file for posterity (or free beer, whichever 
comes first).

[mythtv-users] Re: Re: VLC and MythVideo

[Robert Karaffa]

Nick,
	That doesn't work.  When I select a movie, Myth goes to the 
background, and the VLC GUI pops up along with a Terminal window.  
Terminal shows a VLC error message about "rt offset" or something like 
that, but the movie doesn't play.  I have to ctrl-c to stop VLC, which 
then quits, and then I can quit Terminal to get back to Myth.


Thanks alot for the tips.  I'll keep after!

-Bob K.



 My bad.

Try putting an "open" in front of all that. The one thing i'd be
concerned about is passing the parameter, $1 should do it, but i'm
not sure.

[mythtv-users] Re: VLC and MythVideo

[Robert Karaffa]

I have made a little progress.  I can make VLC play videos from 
MythVideo with this command:


/Applications/vlc/VLC.app/Contents/MacOS/VLC -I dummy

the "-I dummy" part removes the GUI, leaving only the video window.  
However, it will not come to the foreground without a little prompting. 
 I figured out a kludge that works, but it is neither elegant nor, um, 
elegant.  I created an Applescript:


on run
tell application "System Events"  
tell process "VLC"
set frontmost to true
end tell
end tell
end run

Saved this applescript to the Desktop as "vlcfront".

I use an ATI Remote Wonder II to control my Mac frontend, so I assigned 
a key on the remote to run the above applescript.


So, I choose a movie in MythVideo, start it playing, then push the 
remote button that runs "vlcfront" and VLC becomes the frontmost 
application and thus, I get to see the video window.  Like I said, it 
is a kludge, but it will suffice until I can figure a more, um, 
elegant, urm, solution.  YMMV.

[mythtv-users] VLC and MythVideo

[Robert Karaffa]

I've been experimenting with MythVideo, mostly on my OS X frontend. For 
OS X, mplayer is the video player that works best, except I get crackly 
audio on everything.
In Linux, xine seemed to be the best...except I could not get it to 
show subtitles (I like indie and foreign films!).

So I was stuck, until I tried fooling with VLC.
VLC in Linux is the bomb. It shows subtitles, is highly configurable, 
plays .iso files, DVDs, the works. The best part is that the command 
line call in MythVideo is as simple as:

Code:
 vlc

Installation in KnoppMyth R5A16 was a snap:
apt-get install vlc
No dependency probs (yay!).
Latest downloadable version is 0.8.1.
The interface is easily configured on-screen, then it can be put away 
for good. Much better than xine. yay!
For OS X, VLC will work, but it will not come to the foreground when 
called unless I alt-tab to it. Bummer. I'm working on that, but have 
only succeeded in making it crash.
Volume levels of VLC in OS X are much better than mplayer. Louder, 
crisper and clearer. If anybody has any ideas or is also fooling with 
VLC, I'd like to share notes!

[mythtv-users] Re: firewire recording problems

[Robert Karaffa]

Scott,
	You might have to recompile the 6200ch.c binary and hardcode the 
"node" to 2, that's what I had to do to get my DCT6200 to work on my 
KnoppMyth system.
There's a firewire/1394 app called gscanbus 
(http://www.linux1394.org/start_test.php) that you can run in X to 
determine the node of your DCT6400 (I had trouble figuring out how to 
interpret the gscanbus reports...you may not, but good luck anyway!).
I took a look at 6200ch.c in a text editor, found the only reference to 
"node", changed it from "0" to "2", saved it, re-compiled 6200ch.c and 
it worked.  (I think, it's been awhile since I did this and I stupidly 
didn't take notes).


That should make things work for you, I'm pretty sure.

-Bob K.



Firewire Model: DCT-6200
Firewire Connection Type: Point to Point and Broadcast (I've tried 
both)

Firewire Port: 0
Firewire Node: 1

[mythtv-users] re: iconmap.xml problem

[Robert Karaffa]

Pete,
	I had this same trouble.  Somehow, something in iconmap.xml isn't 
right in the latest version of building the iconmap.xml file.  I run 
the latest version of KnoppMyth, by the way.
I got around the problem by copying an archived copy of my iconmap.xml 
into /home/mythtv, then running the import function.  Wish I could 
'splain why it worked that way instead...YMMV.  Hope this helps.

[mythtv-users] Re: Mac 0.18 frontend crashes

[Robert Karaffa]

 AFAIK, R5A16 uses myth .18.1, did you try it with the .18.1 build
from http://www.goof.com/~mmead/MythFrontend-0.18.1.dmg.bz2

I haven't upgraded my backend to R5A16 yet, but I'll report back once
I do.



Thanks for the replies, guys.  I didn't try the 18.1 binary because I 
thought it was for Tiger, and I'm running Panther 10.3.9.


I tried it just now, but it is TV-only.

Also, I've seen the binaries at  www.anthonymittaz.com, but they are 
also TV-only.  I use MythTV for watching movies  via MythVideo, and 
recorded broadcast, mostly, and not so much for LiveTV (commercials 
just suck!).

[mythtv-users] Mac 0.18 frontend crashes

[Robert Karaffa]

hi folks,
	my MythTV backend is KnoppMyth R5A16.  Two of my frontends are Mac 
laptops.  I downloaded the Myth frontend from 
http://www.mythtv.info/moin.cgi/MythOnMacOsx (actually it is hosted on 
http://www.thesniderpad.com/MythFrontend-0.18.dmg).


It crashes when trying to watch TV:

from the Console log:

2005-06-01 22:50:07.075 Connecting to backend server: 192.168.0.2:6543

of type (regR/carP/x!bt)


after this point, Mythfrontend crashes and exits abruptly.

Anyone have any ideas?  This is consistent and reproducible (I 
downloaded the .dmg file on three different computers so a corrupted 
download is not likely).

[mythtv-users] DCT-6200 and KnoppMyth

[Robert Karaffa]

hi folks,
	i've got my KnoppMyth backend working very well (latest KnoppMyth 
alpha).  My PVR-250 works as expected, and I've got my DCT-6200 plugged 
into the PVR-250 via S-video so that I can see channels higher than 
#125.  So far, so good.

-I've connected the DCT-6200 to my backend via firewire, and the 
backend sees the firewire device, all is well to that point.
-the backend allows me to configure the DCT-6200 as an Input Connection 
in mythtv-setup.  it looks like this:
[FIREWIRE Port: 0, Node: 0] (MPEG2TS) -> sTv TV
(*note:  sTv TV is my video source from zap2it)

I'm not sure what "Port" and "Node" mean...how do I configure those?
So far, I've played around with this but not been able to see any 
picture from the device using the firewire connection.  I've been 
looking in the backend for the 6200 channel-changing scripts but 
haven't found them yet (I thought they were included in the 0.17 
release of Myth (and subsequently in the latest alpha of KnoppMyth), 
but I could be wrong).

haven't found a "How-To" for this scenario, yet I've seen some folks 
report that they're using their DCT-6200 as a Video source.

am searching all known sources of info for MythTV, haven't found a 
clear answer or description (and I haven't bothered Jared yet, 
either!).

any help would be most appreciated!

[mythtv-users] Re: OS X frontend/Knoppmyth backend question

[Robert Karaffa]

How is the mac front end accessing the mythvideo files? nfs?
Does the user the mac front end is running have access to the mythvideo
 directory? Is the mythvideo directory setup correctly for the 
frontend?
Does a verbose log tell you anything?

Ivor,
	I started to reply, then had to rush off to other duties.  Your 
questions pushed me in the right direction, thanks a bunch!  after i 
returned, i sat down and thought about how the Mac was mounting the nfs 
server that holds my multimedia content.
	both KnoppMyth machines nfs-mount volumes served by a separate nfs 
server for movie and music material.  in addition, movie cover art is 
also held by another separate nfs server (an old Mac G3 that runs my 
house!).  the KnoppMyth machines mount those nfs volumes in an 
identical fashion, thus allowing (i think) the mythconverg database to 
function correctly.
	The Mac, however, hadn't been configured correctly in regards to 
mounting the aforementioned nfs volumes.  once that was done, 
everything automagically worked!  yay!

I had to open a terminal on the Mac, become root, and create /mnt and 
/myth.  in /mnt i created another directory (/downloads) which holds 
cover art, amongst other things).  in /myth, i created /video, and then 
in /video i created /video3 and /video4 (the nfs volumes that contain 
videos).  I used NFS Manager to create the mount points for the nfs 
volumes.

Since MythOnMacOSX was expecting those directories to exist (due to the 
way I configured the backend...is my thinking correct here?), when they 
were not found, MythVideo would error when trying to play a movie.  
Having a Console open when doing this really helped, along with Ivor's 
queries.

Thanks again, Ivor!

[mythtv-users] OS X frontend/Knoppmyth backend question

[Robert Karaffa]

hi folks,
	i've got my Knoppmyth frontend running nicely, and a Knoppmyth 
frontend working well.  however, i'm struggling to configure my Mac 
frontend.  All are running 0.17, and the Mac is using the 0.17/plugins 
binary downloaded from http://whpress.com/mythtv/.

what works:
-TV, MythWeather, on all
-MythVideo on backend and Knoppmyth frontend
what doesn't work:
-MythVideo on the Mac
I've learnt the hard way not to touch the Video Manager on the Mac 
until I've figured out how things work on it.

The Knoppmyth frontend sort-of self-configured.  The Mac, on the other 
hand...haven't figured that one out, yet.

Any hints, anyone?
Just to be clear, the Knoppmyth frontend successfully connects to the 
backend and is 100% functional.  The Mac frontend can connect, but 
MythVideo can't find the video files and cover art.

[mythtv-users] OS X

[Robert Karaffa]

hi folks,
	i've been reading MythOnMacOSX and have managed to install a 
near-working frontend on my old headless G4TiBook (500MHz, 784 RAM).  
this TiBook outputs video to my TV via s-video.  normally, i watch 
movies using VLC, which works just fine, but the interface is too 
computer-oriented (i.e., requires keyboard/mouse to select movies, 
play, pause, etc.).  not any fun to do when trying to sit comfortably 
on my fat arse on the couch.

my backend is a KnoppMyth laptop, and it works very well (latest 
KnoppMyth plus a couple of plugins).  nothing special.  500MHz Dell 
Latitude.  KnoppMyth is very easy to install/configure.

i keep an old Mandrake box as a multimedia server.  it houses a couple 
of 200Gb drives that hold all of my movies/music.  my KnoppMyth box 
nfs-mounts the Mandrake box.  works wonderfully.

my questions concerning MythOnMacOSX:
1)  i've managed to install the CVS version of Myth w/plugins.  i can 
nfs-mount my multimedia server to allow access for video playback on 
the Mac.

How do I playback movies?
I've installed MPlayer for OS X.
in the setup screens for MythVideo, I can get MPlayer to start using:
"open /Applications/MPlayer.app (and the rest of the commands like -fs 
--no-splash -zoom %s")
Select a movie, and  MPlayer starts, but it also brings itself to the 
front, along with the Finder and the Dock.

something I'm not doing correctly here.
2)  i don't have a TV tuner card of any kind right now.  not interested 
in it at the moment.  how does that impact the fact that my backend is 
0.16 and my MacMyth frontend is not?
