Description

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.
