I objected to this indiscriminate copying in a previous review. There is no reason to expect side data to apply to the whole stream just because it happens to apply to the first frame. For many side data types it does not even make sense, as they are fundamentally per-frame. -- Anton Khirnov _______________________________________________ ffmpeg-devel mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
