Current transcode may not be able to handle it without some changes. If you could tell libavcap to output in YUV420P, YUV422P or RGB, or convert it yourself you could use the raw input module. For example this would work for YUV420P: transcode -i v4l.out -o bla.avi -x raw -g 640x480 -V yuv420p -y ffmpeg -F mpeg4 If you use transcode 1.0.x this might work for YUY2: transcode -i v4l.out -o bla.avi -x raw -g 640x480 -uyvy -y ffmpeg -F mpeg4 But the colors will probably be backwards. stefan
