It seems it's not really realated to matroska itself. It seems to be due to generic ffmpeg conversion code behaving differently when having one added unknown stream that he just drop during the conversion. Maybe it still try to do some synchronization or some timestamps handling with the dropped stream ? Anyway, just adding those lines in any demuxer should be enough to trigger the bug in ffmpeg: st = av_new_stream(s, id); st->codec->codec_type = CODEC_TYPE_ATTACHMENT; I have not investigated further. ---------- priority: important -> normal status: new -> open substatus: new -> reproduced type: patch -> bug ______________________________________________________ FFmpeg issue tracker <[EMAIL PROTECTED]> <https://roundup.mplayerhq.hu/roundup/ffmpeg/issue412> ______________________________________________________
