[FFmpeg-devel] Errors when encoding yuv to mpeg4: Could not find input stream matching output stream, and [mpeg4 @ 0x9dbce80] header damaged

[Kurtis Smith]

hi,

I am using ffmpeg built based on the latest checkout against gcc4.2. I
wanted to encode the "foreman" QCIF clip into raw MPEG4 stream, but with
both formats m4v and mp4, I got errors. Logs are attached below. Am I
missing anything?

When I built ffmpeg, I did not link the external libx264, so it should be
MPEG4 part2 not part10.

Thanks for your attention.
