This is a different known problem but is completely unrelated
to the encoder in-progress ending.
What happens here is that there is a variable called framesPlayed
which is more accurately frames decoded. During playback, the frames
are decoded and stuffed into vbuffers which the player uses to step
through the upcoming frames on time (when the vbuffers are empty
the player has to stop to wait for more and reports "prebuffering
If you hit pause when framesPlayed is 1000, there may be 20 frames
in the vbuffers so the frame displayed is 980. the first step
forward decodes frame 1001 so the new displayed frame is 21 frames
later than the paused frame.
