hi,

Please help me a bit.
I am trying to transcode (record) a video from my webcam.
But I do not succeed:

vlc -v v4l:///dev/video0 --sout '#transcode{vcodec=mp2v,vb=4096,acodec=mp2a,ab=192,scale=1,channels=2,deinterlace,audio-sync}:std{access=file,mux=ps,url="/tmp/output.ps.mpg"}'

...
[00000510] main input debug: `v4l:///dev/video0' successfully opened
[00000512] main stream output debug: adding a new input
[00000512] main stream output debug: adding a new input
[00000513] stream_out_transcode private debug: creating video transcoding from fcc=`I420' to fcc=`mp2v'

[00000555] main encoder debug: looking for encoder module: 6 candidates
[00000555] ffmpeg encoder debug: libavcodec initialized (interface 3352064 )
[00000555] ffmpeg encoder error: cannot find encoder MPEG-2 Video
[00000513] stream_out_transcode private error: cannot find encoder ((null))
...

What I am doing wrong? I tried the debian package 0.8.6c. Then from vlc's repository 9svn...
Now I even compiled my own version of ffmpeg and vlc. The error messages
are always the same.

Thanks in advance.

Regards,
