[MEncoder-users] Mencoder killed when using vfw

[Yoann Maheo]

Hi,

I have a problem with mencoder when I try to encode a movie to FLV 
format with VP6 for video.

So I use vfw to load vp6vfw.dll library.

The example use a mpg video for the input but a WMV video give the same 
result.
Mencoder is killed without any reason, and said nothing.
The encoding don't start.

nobody at nobody ~/encoding $ mencoder "/video/test_1_720x480_2000k.mpg" -o 
"/video/test_1_640x427_350k.flv" -ovc vfw -xvfwopts 
codec=vp6vfw.dll:compdata=file_encod.mcf -oac mp3lame -lameopts 
cbr:br=64 -af lavcresample=22050 -vf yadif,scale=640:427,flip -of lavf
