Comment (by v0lt):
Here is an example with a non-zero keyed keyframe.
{{{
ffmpeg -i "movie.mp4" -ss 603.480 -to 1207.840 -c copy "movie.2.mp4"
ffplay "movie.2.mp4"
}}}
I also noticed that frame 603.480 is in both files (movie.1.mp4 and
movie.2.mp4), although the previous frame with time 603.440 is a P-frame.
IMHO, it should be the last frame for the movie.1.mp4. I moved the range
to "-ss 0.000 -to 603.470", but it did not change anything.
