Hi,
I have a problem with mencoder and I don't find an answer searching all
archives... I am able to grabb video from my v4l device (rivatv driver) but I
can't record sound. The sound comes from line-in, so I tried to use
"forceaudio" and "adevice" like this:
mencoder tv:// -tv
driver=v4l:norm=SECAM:input=0:width=352:height=288:adevice=/dev/
dsp:forceaudio -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=900 -oac mp3lame -o
output.avi -v
or
mencoder tv:// -tv
driver=v4l:norm=SECAM:input=0:width=352:height=288:adevice=hw.0:alsa:forceaudio
-ovc lavc -lavcopts vcodec=mpeg4:vbitrate=900 -oac mp3lame -o output.avi -v
because I am using alsa. But, for each case, when playing the movie, mplayer
says "Audio: no sound". So I think this not a problem from my mixer because
mplayer does not find the sound information in the movie, no ? I tested the
configuration of my soundcard with /usr/bin/record and it works. I compiled
frome source mplayer from MPlayer 1.0pre1-3.3.1. I added the log of what each
command does. At the end, there is the result of ./configure (maybe some
option of my compilation are wrong).
Any idea ?
Thanks,
JFL
