[MPlayer-users] Bug or misconfig in tv audio language support?

[Yan Seiner]

I am trying to capture a video tape that has Japanese on one channel and
English on the other.  So far, no luck.

My bt848 card is a mono card, so I am running the composite signal from
the vcr into the tv card, and the audio into the sound card.  This
works; I get both stereo channels.

The problem comes when I want to record Lanuage 1 or Language 2.  I
can't.  I either get nothing, or both channels.

I am using 0.90 - I tried CVS this morning, but it won't compile :-(

Here's my mencoder line:

mencoder -tv
on:driver=v4l:input=1:width=720:height=480:norm=NTSC:forcechan=2:amode=2
-vop scale=360:240,crop=704:464:8:8,pp=ci
-ovc lavc -lavcopts vcodec=mpeg4:vbitrate=1200:keyint=100:aspect=4/3
-oac mp3lame -lameopts cbr:mode=0:br=128 -o little_mermaid_2.avi

Basically, the amode in the tv part is ignored (no surprise there, since
sound is coming in via soundcard.)  But I can't find a way to tell
mencoder to only use Lang 1 or Lang 2.  But if I don't use forcechan, I
only get Japanese (left channel).  No matter what, the amode appears to
be ignored.

I tried noaudio for the tv section; no sound at all.  So it seems that
if you use composite video in and sound in via soundcard, forcechan and
amode are partially implemented/broken or I don't understand something.

Here's the mencoder output:

[yan at poseidon disney_cartoons]$ mencoder -tv
on:driver=v4l:input=1:width=720:height=480:norm=NTSC:forcechan=2:amode=2
-vop scale=360:240,crop=704:464:8:8,pp=ci
-ovc lavc -lavcopts vcodec=mpeg4:vbitrate=1200:keyint=100:aspect=4/3
-oac mp3lame -lameopts cbr:mode=0:br=128 -o little_mermaid_2.avi

Requested mode was language1, but v4l still reports mono.
You may need "forcechan" option to force stereo/mono audio recording.
