Summary

Types

t()

Type that represents an CUDACodec.NVSurfaceToColorConverter struct.

Functions

convert(named_args)
convert(self, yuv, surfaceFormat, outputFormat)

Variant 1:

Performs the conversion from the raw YUV Surface output from VideoReader to the requested color format. Use this function when you want to convert the raw YUV Surface output from VideoReader to more than one color format or you want both the raw Surface output in addition to a color frame.

convert(self, yuv, surfaceFormat, outputFormat, opts)

Variant 1:

Performs the conversion from the raw YUV Surface output from VideoReader to the requested color format. Use this function when you want to convert the raw YUV Surface output from VideoReader to more than one color format or you want both the raw Surface output in addition to a color frame.
