Comment (by ubitux):
That's probably because they work on a constant frame rate default.
You can use -vsync vfr to copy this behavior with ffmpeg. You will have
the frame accuracy, but you will loose the "timings": images don't have
timestamps, so it's assuming constant frame rate, and thus has to
duplicate to keep playback as correct as possible.
