From: Misty De Meo <mistyde...@gmail.com> I've updated this so it applies on master.
This patch is still necessary; the wrong duration is most obvious when remuxing Cinepak from FILM files without reencoding. For example, one sample video I have has a timebase of 30, and most frames last for two ticks. When remuxing in a format which uses the duration, this can leave gaps in the time codes. Here's an example from an original video and one remuxed using FFmpeg. The first number is the absolute timestamp, and the second number is the duration value. In the first set, from the original video, you can see that the timestamps increase by 2 each tick and the time between frames also increases by 2 each tick. In the second set, produced by FFmpeg, the timestamps still increase by 2 but the time between frames is now marked as 1. This is fixed by this patch. 80000002 00000002 80000004 00000002 80000002 00000001 80000004 00000001 Misty De Meo (1): Sega FILM: set dts and duration when demuxing libavformat/segafilm.c | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) -- 2.17.0 _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
