"ffmpeg -r 25 -i in.file ... out.file"
usage: ffmpeg [options] [[infile options] -i infile]... {[outfile options]
outfile}…
In here, [infile options] is "Video options”.
look at help of ffmpeg:(cmd is 'ffmpeg -h | more’).
/*

写道：
For video codec H.264 there are two parameters:
Framerate (e.g. 25 or 30 or 29,97)
and
keyframe interval (I guess measured in seconds after the last keyframe .e.g 50
or 200):
What are the corresponding cmdline parameters for ffmpeg?
How can I tell ffmpeg to use the same values as the input?
Thank you
Ben
