So you and I would presume it's just faster because of some internal
mechanism for extra threading?
I wonder if it's related to
https://github.com/FFmpeg/FFmpeg/commit/47b812e9cec3e0b2

It would be interesting to see if it shows the same speed difference
in linux that it does in windows.  But besides that, I don't know what
it is :)
