Hi,
Before trying to develop a new feature, and diving in the code base, I wanted
to know if it currently exists, or is already in a work-in-progress task:
When cutting a video with no re-encoding:
ffmpeg -ss 120 -t 60 -i input.mp4 -c copy output.mp4
the result is often choppy or non-smooth in the first seconds, because the cut
point doesn't necessarily coincide with a keyframe, at least on some players
(such as Media Player Classic, etc.).
Some more complex solutions involve reencoding just the beginning until the
next keyframe, and then use copy codec for the rest of the video, and then
concatenating, all of this requiring multiple calls of ffmpeg.
Is there a feature already in development that would allow to do this in one
single pass of ffmpeg, without multiple calls and concatenation?
Something like:
ffmpeg -ss 120 -t 60 -i input.mp4 -c copy -reencodebeforekeyframe output.mp4
Thanks,
Basj
