What's in your ~/.mplayer/config file? If the 'total time' and 'total
frames' are not printed by default, then there's something weird going

That will give you the average FPS over that small chunk of the file,
but it won't necessarily be the same as the average FPS of the entire
file; if the frame rate changes later on, the average FPS will be

In point of fact, I noticed that exact effect in the course of testing
to make sure that the numbers I expected were in fact gettng printed.
Once I let the video finish 'playing' and got total time of 420.2
seconds with 11822 frames, for an average FPS of ~28.13422; another
time, I interrupted it early on at 35.0 seconds (by coincidence) and 832
frames, for an average FPS of 23.77143. Considering the desync I
sometimes get in non-variable-FPS files whose FPS value is off by (as
far as I can tell) about 0.1 frame per second, I'd say that 4.36 frames
per second is a very significant difference.

side of it.
