==========================================================================
I used lavf demuxer(MPEG2-TS) and mux it(LAVF-AVI)
and width and height of video_stream is ZERO
'[avi @ 0xb42038]dimensions not set ' came out consequently.
i think it might be caused by following.
1. hard-coded core(mencoder)/eg, it can't deliver stream_t between demuxer and
muxer properly. finally it brokes entire program.
2. it's not problem of mencoder. ask for ffmpeg_devel :)
if i had enough time, i can gather more information but that's all.
