Comment:
Vulkan's extension VK_KHR_sampler_ycbcr_conversion doesn't give access to
the YUV components to add a multiplier to handle high bit videos (10 or
above). I changed my shaders to handle YUV conversion the same way as
OpenGL.
color.r = 64.25 * texture(sTexture[0], In.uv.xy).r;
color.g = 64.25 * texture(sTexture[1], In.uv.xy).r;
color.b = 64.25 * texture(sTexture[2], In.uv.xy).r;
