Detailed Description

Video writer interface, see createVideoWriter().

Available if Nvidia's Video Codec SDK is installed.

Only Codec::H264 and Codec::HEVC are supported with encoding support dependent on the GPU, refer to the Nvidia Video Codec SDK Video Encode and Decode GPU Support Matrix for details.
