Component: undetermined → avcodec
Keywords: h263i added
Reproduced by developer: set
Status: new → open
Version: unspecified → git-master

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

comment:2 by reimar, 14 years ago

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.

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 by Carl Eugen Hoyos, 13 years ago

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