Subject: [PATCH] vc4/kms: vc4_plane: Support 2020 colourspace for yuv
|
|
planes
|
|
|
|
https://gist.github.com/popcornmix/6b3e23103c60170b02b148e0ba5d6ed7
|
|
|
|
is the script used to generate the 601, 709 and 2020 colourspaces.
|
|
I've regenetated the existing ones using script so it is reprocable
|
|
but there are lsb dfferences compared to values here (copied from spec)
|
|
whose origin is now lost.
