Struct opencv::cudacodec::CUDA_VideoReader

pub struct CUDA_VideoReader { /* private fields */ }

Video reader interface, see createVideoReader().

Available if Nvidia’s Video Codec SDK is installed.

Decoding support is dependent on the GPU, refer to the Nvidia Video Codec SDK Video Encode and Decode GPU Support Matrix for details.

Note:

• An example on how to use the VideoReader interface can be found at opencv_source_code/samples/gpu/video_reader.cpp
