The file in question is here: http://ia331209.us.archive.org/0/items/Patent_Absurdity/Patent_Absurdity_HD_3540kbit.ogv A screenshot is attached to show the distortion. The video is encoded at an interesting resolution: 1280x1088, which may contribute to the problem. One or more of these FFmpeg revisions have not been backported to 0.6 I guess: r23537, (r25050 not directly related), r25051, r25052, r25073 ___ pkg-multimedia-maintainers mailing list pkg-multimedia-maintainers@lists.alioth.debian.org http://lists.alioth.debian.org/mailman/listinfo/pkg-multimedia-maintainers

I was under the impression that if I can reproduce a bug in mplayer and ffplay, I should submit it as an FFmpeg bug rather than mplayer. Is this not the case? Nathan A.

You did nothing wrong in reporting this as an MPlayer bug, however FFmpeg/ffplay does not use the slice rendering API (except possibly if you use the right libavfilter filters) so bugs that are exclusive to that will not be reproducible with ffplay even if (like in this case) it actually is an FFmpeg bug. ___ pkg-multimedia-maintainers mailing list pkg-multimedia-maintainers@lists.alioth.debian.org http://lists.alioth.debian.org/mailman/listinfo/pkg-multimedia-maintainers
