Just though i'd put it somewhere public. It's a very simple patch to
parallelize yadif deinterlacing. Preferably it should be done using
normal pthreads, but the threading code in ffmpeg seem geared to
decoding and not filtering + this ended up so silly simple.

Had weird issues with openmp to start with, 100% usage on first
decode, but then every following tries nicely distributed between
cores.
