Comment:
This seems a bug in the framerate filter, pending_input_frames starts
drifting apart between pass 1 and 2 caused by different patterns of
request_frame calls and ultimatly resulting in diferent output frame
numbers.
This on my box only reproduces with -threads 1 (but any x264 version)
i do not think this is a regression, the commit in question indicates that
flushing did not work correctly before and this ticket indicates it still
doesnt work.
Ill leave this to stefano and paul as they know the code better
