cudaBGR8ToRGBA32()

cudaError_t cudaBGR8ToRGBA32	(	uchar3 *	input,
		float4 *	output,
		size_t	width,
		size_t	height
	)

Convert 8-bit fixed-point BGR image to 32-bit floating-point RGBA image.

cudaNV12SetupColorspace()

cudaError_t cudaNV12SetupColorspace

(

float

hue = 0.0f

)

Setup NV12 color conversion constants.

cudaNV12SetupColorspace() isn't necessary for the user to call, it will be called automatically by cudaNV12ToRGBA() with a hue of 0.0. However if you want to setup custom constants (ie with a hue different than 0), then you can call cudaNV12SetupColorspace() at any time, overriding the default.
