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.

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