I don't think this is a particularly useful testcase:
It takes very long but mostly tests other things.

Did you test if using ffmpeg -benchmark -f rawvideo -i /dev/zero... 
showed different results?
I believe this should be both easier and faster to test.

Without any data, I would have thought that this is the most 
important function (and "no. of calls" seems to confirm this).

Why is this not faster?
Can you confirm with START_TIMER / STOP_TIMER that there is no 
gain?

Thank you, Carl Eugen
