Comment (by Lastique):

 Replying to [comment:1 cehoyos]:
 > Is this not reproducible with current FFmpeg git head?

 I did not test git head, but looking at the code of
 avcodec_encode_video2() in git master it still calls
 av_packet_merge_side_data() so it must have the same problem.

 > How can I reproduce the problem with ffplay?

 I don't know how to make ffmpeg request mb_info from the command line. I
 have an output video file we got with our application that shows decoding
 errors I described. I can upload it tomorrow, if you're interested. By the
 way, the same file is played without errors by libav's ffplay. I guess,
 it's more tolerant towards the junk at the end of encoded frames.
