Struct opencv::cudacodec::VideoWriter

pub struct VideoWriter { /* private fields */ }

Video writer interface.

Available when built with WITH_NVCUVENC=ON while Nvidia’s Video Codec SDK is installed.

Encoding 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 videoWriter class can be found at opencv_source_code/samples/gpu/video_writer.cpp

Trait Implementations

impl Boxed for VideoWriter

unsafe fn from_raw(ptr: *mut c_void) -> Self

Wrap the specified raw pointer

fn into_raw(self) -> *mut c_void

Return an the underlying raw pointer while consuming this wrapper.

fn as_raw(&self) -> *const c_void

Return the underlying raw pointer.

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

Return the underlying mutable raw pointer

impl Drop for VideoWriter

fn drop(&mut self)

Executes the destructor for this type.

impl VideoWriterTrait for VideoWriter

fn as_raw_mut_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().
