No audio in streaming files

[nickfoti]

I have the latest release installed as well as the latest mdd/vlc/
ffmpeg on my backend/frontend. I can stream video from the recordings
and video areas but never get any sound.

I had an issue running MDD initially, but I think I have that sorted
out by running, as root on boot:

/usr/bin/mythlcdserver

I do notice that if I run that from a command line I get a warning
"Could not connect to LCDd: connection refused"

The Install instructions state to run /usr/bin/mdd on boot, but I do
not have that file.

Any tips on where I should start to debug the issue of the missing
sound?

Thanks!

I messed with the transcode settings in mdd.pl, trying different audio
codecs (re-install with perl script, restart mythlcdserver) without
any success.

Out of curiosity I installed on a Droid X to see if I could replicate
the problem using the same backend. Unfortunately, I could not get
video playback to work at all on the DroidX, exits out with the
message "Sorry this video cannot be played"

This should be run automatically by mythfrontend if you have enabled
the LCD options in the frontend setup.

Not a problem.

MDD would be installed to that location if you had performed a
'backend-only' install (by specifying --backend).

On a combined frontend/backend, it installs to /usr/bin/mythlcdserver
and, as stated above, should be run automatically by mythfrontend.

As a first step, let's have a look at /tmp/ffmpeg.log and /tmp/vlc.log.

Ah, thank you very much. That solved the problem I was having with no
audio on my Captivate. I noticed that /tmp/vlc.out was complaining
about ffmpeg not being compiled with mp4a. I re-installed libavcodec-
extras from the medibuntu repository and that solved that issue. btw-
I don't have /tmp/vlc.log or /tmp/ffmpeg.log - I'm assuming you meant /
tmp/vlc.out and /tmp/ffmpeg.out

Things seem to be working well on the captivate now, but I have
another issue with sound cutting out after a few seconds in some
recordings. Here are the last few lines of my /tmp/vlc.out file:
[0x9f58218] stream_out_transcode stream out debug: drift is too high,
resetting master sync

I do have another issue with my Motorola devices (droid x and xoom). I
suspect that the issue is with the h264 codec and the motorola devices
not having support for them. I noticed another suggestion in these
boards to replace the vlc transcode setting:
vcodec=h264,venc=x264{no-cabac,level=30,keyint=50,ref=1,bframes=0}
with:
vcodec=mp4v
I also tried:
vcodec=h263
Neither of those worked for me.

Here is a copy of my $stream_cmd from mdd.pl:

'ffmpeg -i %FILE% -vcodec rawvideo -acodec pcm_s16le -deinterlace
' .
'-s %WIDTH%x%HEIGHT% -ac 2 -ar 48000 -copyts -async 100 -f asf -y
- ' .
'2>/tmp/ffmpeg.out | /usr/bin/vlc -vvv -I dummy - ' .
'--sout=\'#transcode{vcodec=h264,venc=x264{no-
cabac,level=30,keyint=50' .
',ref=1,bframes=0},vb=%VB%,threads=%THR%,width=%WIDTH%,height=
%HEIGHT%,' .
'acodec=mp4a,samplerate=48000,ab=%AB%,channels=2,audio-sync}' .
':rtp{sdp=rtsp://0.0.0.0:5554/stream}\' >/tmp/vlc.out 2>&1';

Thanks for any help...
