Struct opencv::cudacodec::CUDA_VideoWriter

pub struct CUDA_VideoWriter { /* private fields */ }

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.

Note:

• An example on how to use the VideoWriter class can be found at opencv_source_code/samples/gpu/video_writer.cpp

Trait Implementations

impl Boxed for CUDA_VideoWriter

unsafe fn from_raw( ptr: <CUDA_VideoWriter as OpenCVType<'_>>::ExternReceive ) -> Self

Wrap the specified raw pointer

fn into_raw( self ) -> <CUDA_VideoWriter as OpenCVTypeExternContainer>::ExternSendMut

Return the underlying raw pointer while consuming this wrapper.

fn as_raw(&self) -> <CUDA_VideoWriter as OpenCVTypeExternContainer>::ExternSend

Return the underlying raw pointer.

fn as_raw_mut( &mut self ) -> <CUDA_VideoWriter as OpenCVTypeExternContainer>::ExternSendMut

Return the underlying mutable raw pointer

impl CUDA_VideoWriterTrait for CUDA_VideoWriter

fn as_raw_mut_CUDA_VideoWriter(&mut self) -> *mut c_void

fn write(&mut self, frame: &impl ToInputArray) -> Result<()>

Writes the next video frame.

fn release(&mut self) -> Result<()>

Waits until the encoding process has finished before calling EncoderCallback::onEncodingFinished().

impl CUDA_VideoWriterTraitConst for CUDA_VideoWriter

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for CUDA_VideoWriter

fn drop(&mut self)

Executes the destructor for this type.
