comment:1 Changed 5 years ago by cehoyos

  • Component changed from undetermined to avcodec
  • Keywords h263i added
  • Reproduced by developer set
  • Status changed from new to open
  • Version changed from unspecified to git-master

Additional samples in http://samples.multimedia.cx/A-codecs/IMC/
Not a regression, also reproducible with c978997a.

comment:2 Changed 4 years ago by reimar

None of the files in A-codecs/IMC show relevant corruption.
Are you sure the file is supposed to look better? A losslessly compressed reference of how it should decode would probably help to figure it out, because I don't think the error messages should have much to do with what the actual issue is.

comment:3 Changed 4 years ago by reimar

Ah, I see now. We just throw away the PB motion vectors, see libavcodec/ituh263dec.c:836.
See the two ff_h263_decode_motion that do not get their results assigned anywhere.

comment:4 Changed 4 years ago by cehoyos

The artefacts were fixed by Michael, ffmpeg is still too verbose for the sample.

comment:5 Changed 4 years ago by cehoyos

comment:6 Changed 2 years ago by cehoyos
