Those uuids need to match the uuid instance tag (0x3C0A) on a track written in mxf_write_track. then the uuid ref on the track needs to match the one on the sequence, and then the one the sequence needs to match the one on the component. would you rather the instance id be a argument to each of the write functions? for example: mxf_write_package(AVFormatContext *s, MXFPackage *package, int track_uuid_offset) mxf_write_track(AVFormatContext *s, AVStream *st, MXFPackage *package, int instance_id) would that be more explicit? > > // write user comment refs >> if (mxf->store_user_comments) { >> @@ -1402,12 +1401,14 @@ static void mxf_write_package(AVFormatContext >> *s, MXFPackage *package) >> mxf_write_track(s, mxf->timecode_track, package); >> mxf_write_sequence(s, mxf->timecode_track, package); >> mxf_write_timecode_component(s, mxf->timecode_track, package); >> + mxf->track_uuid_offset++; >> for (i = 0; i < s->nb_streams; i++) { >> AVStream *st = s->streams[i]; >> mxf_write_track(s, st, package); >> mxf_write_sequence(s, st, package); >> mxf_write_structural_component(s, st, package); >> + mxf->track_uuid_offset++; >> >> > > /Tomas > _______________________________________________ > ffmpeg-devel mailing list > ffmpeg-devel@ffmpeg.org > http://ffmpeg.org/mailman/listinfo/ffmpeg-devel > _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
