So the output from ffmpeg produces 100 frames!

So this could be an issue with the way ffprobe and ffmpeg reads the duration of the mpeg file - displaying 00:00:03.96 rather than 00:00:04.00, even though the whole 4 seconds are there somewhere in the file.

Is this a bug?

(also an issue with the way quicktime displays the file as it's not showing the last frame.)
