Description

Using the new colorspace information in AVCodecContext, we can implement GetSourceDataGammaLevel? and add the colr/nclc/whatever it is atom to signal the YUV colorspace. That should fix some color incompatibilities with Apple H.264 and make HD look better.

(if no codecs actually export this, it needs to be implemented in lavc, or we can just use bitstream_info)

Also need to set color info (and fix the destination colorspace) for subtitle tracks, handle custom YUV matrices, and handle chroma siting (including fixing ColorConversions? if necessary).

(In [1170]) Set video colorspace info on import via 'nclc'.

Fixes the colors for every video ever. Closes #410
