POC attached.

comment:3 Changed 9 years ago by richardpl

Patch works but it is not perfect, there is one error in decoding.

Should avcodec_set_dimensions() be used for this?

comment:4 Changed 9 years ago by richardpl

Attached patch does not have error while decoding and plays OK in ffplay and at least plays in mplayer bigger part of sample.
MPlayer for some reason dumps few last frames for reason yet to find.

Fixed in master.

comment:6 Changed 9 years ago by cehoyos

Did you test?
It does not work correctly here...

comment:7 Changed 9 years ago by richardpl

Does work with ffplay, doesn't with ffmpeg. mplayer think it gets EOF and exits too early.

comment:8 Changed 9 years ago by cehoyos

That's why I think the problem has not been fixed.
ffmpeg is the primary application.
