This seems like it should be in a separate patch, though - it is changing a different behavior than what this patch does. > + frag_stream_info = get_frag_stream_info(frag_index, index, dst_st->id); > + timestamp = get_stream_info_time(frag_stream_info); > + if (timestamp != AV_NOPTS_VALUE) > + return timestamp; I did look at that, but I do not think it can be. get_stream_info_time is not equivalent to what is here. get_stream_info_time will eventually fall back to frag_stream_info->tfdt_dts, where as this code falls back to frag_stream_info->sidx_pts even if it is AV_NOPTS_VALUE. It would be a behavior change do use get_stream_info_time here. - Derek _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
