I needed to encode to mov/mp4 with a timebase of 1/600 and the output was not as expected.
I discovered the reason is a silent limiting of a track timebase added here: https://github.com/FFmpeg/FFmpeg/commit/b02493e47668e66757b72a7163476e590edfea3a The patch attached provides a new flag to disable the timebase limit, and in the case that the limit is applied, a debug message is logged to prevent future user confusion. vectronic (2): avformat movenc add flag to disable silent limit on timescale avformat movenc add flag to disable silent limit on timescale libavformat/movenc.c | 8 ++++++-- libavformat/movenc.h | 1 + 2 files changed, 7 insertions(+), 2 deletions(-) -- 2.24.2 (Apple Git-127) _______________________________________________ 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".
