Member Function Documentation

convert()

virtual bool cv::cudacodec::NVSurfaceToColorConverter::convert ( InputArray yuv, OutputArray color, const SurfaceFormat surfaceFormat, const ColorFormat outputFormat, const BitDepth bitDepth = BitDepth::UNCHANGED, const bool planar = false, cuda::Stream & stream = cuda::Stream::Null() )

pure virtual

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.

Parameters

yuv	The raw YUV Surface output from VideoReader see SurfaceFormat.
color	The converted frame.
surfaceFormat	The surface format of the input YUV data.
outputFormat	The requested output color format.
bitDepth	The requested bit depth of the output frame.
planar	Request seperate planes for each color plane.
stream	Stream for the asynchronous version.
