[vlc-devel] [PATCH 0/8] Xbox fixes

The Xbox has some issues where standard Windows has no problem:
- it cannot decode 4K H264 sources
- it assumes the pixels are in "studio" range even though our code
works in "full" range.

This set of patches fixes these 2 issues. When we detect the Xbox
we forbid 4K H264 in D3D11VA and we to a full->studio conversion
in the pixel shader.

Steve Lhomme (8):
  dxgi_fmt: add a helper function to detect the Xbox One
  d3d11va: workaround for Xbox decoder limitations
  d3d11: include initguid.h before d3d11.h so we have all the class IIDs
  direct3d11: make sure ppColorspace is always set a value
  direct3d11: the magic value for the white point is 16/256
  direct3d11: make the pixel shader matrices non-const
  direct3d11: pass the whitepoint and colorspace matrices to the RGB
    pixel shader
  direct3d11: tweak the pixel shader for the Xbox
