New submission from Zarbis <[email protected]>:

I've written simple transcoding program according to api examples. When trying
to seek in output file i can seek to correct position, but video is corrupted
tell next key frame. Mplayer gives this warning each time i try to seek: [mpeg4
@ 0x7f21e8f51b80]warning: first frame is no keyframe.
For CODEC_ID_MPEG4 key frames are exactly first and each 30th (like gop size
paramether).
File 'q.mp4' not attached - you can download it from
