This patch adds frame multithreading to the DNxHD decoder. Tested and
confirmed working on all samples I have, but needs review, since I'm a
ffmpeg noob. Results from this sample:
http://www.limpans.com/downloads/AVID/DNxHD/NTSC/Swans220X.zip (598 MB)
1 thread: 28 fps
4 threads: 144 fps
Tested on an overclocked i5 2500K (4 cores, 4 threads).
I tried using git send-email but got all kind of errors so I'm posting it
here. Hope everything's fine.
