[MPlayer-users] Trouble caputring audio with saa7134 tv card

[Michael Meltner]

Hello,

looking for some hint on some trouble I have getting audio to work
with my mencoder setup. The encoded AVI files does not contain any
audio stream, neither from the TV card itself, nor from the line-in
of my sound card.

Xawtv runs smoothly, and I can separately record the TV audio with eg
the command line tool 'record' , no problems here.

I use Kernel 2.4.21 with the Kraxel patch for v4l2 and his saa7134 
driver version 0.28. Now mencoder dumps this output:

What is this ioctl failure? Why is the line-in sound not recorded
although the mixer setting is unmuted and set to 'capture'? 
(Otherwise 'record' would not work)

What am I missing here?

command:
mencoder -tv on:driver=v4l:norm=pal:channel=E2:width=192:
height=144:forceaudio:amode=0:forcechan=1:adevice=/dev/dsp0:
audioid=0:volume=65000 -ovc lavc -lavcopts vcodec=mpeg4:
vbitrate=900 -oac pcm -vop pp=lb -o test
