[FFmpeg-devel] colorspace.h

[Chris]

If ffmpeg is to support webm, VP8, VP9, etc., the following should be noted (from Wikipedia):

<< The VP9 format supports the following color spaces: Rec. 601, Rec. 709, Rec. 2020, SMPTE-170, SMPTE-240, and sRGB. >>

Also, support for BT.2020 should be kept in mind.

My demo program will be written with both 601 and 709. It will be expandable to other color spaces.

found what I believe to be some questionable code in colorspace.h. I have
modified the code to what I believe is correct but am unable to compile ffmpeg
myself on Windows to test my modifications, despite spending many hours trying
to do so and reading several how-to's.

here if people would like, but someone who is better equipped to compile ffmpeg
would have to compile it.

can you post a patch that shows the modifications
and explain what is
wrong before and how its improved

Thanks
