Member Function Documentation

acquireBitStream()

virtual uchar* cv::cudacodec::EncoderCallBack::acquireBitStream ( int *  bufferSize )

pure virtual

Callback function to signal the start of bitstream that is to be encoded.

Callback must allocate buffer for CUDA encoder and return pointer to it and it's size.

onBeginFrame()

virtual void cv::cudacodec::EncoderCallBack::onBeginFrame ( int  frameNumber, EncoderCallBack::PicType  picType  )

pure virtual

Callback function to signal that the encoding operation on the frame has started.

Parameters

frameNumber
picType	Specify frame type (I-Frame, P-Frame or B-Frame).

onEndFrame()

virtual void cv::cudacodec::EncoderCallBack::onEndFrame ( int  frameNumber, EncoderCallBack::PicType  picType  )

pure virtual

Callback function signals that the encoding operation on the frame has finished.

Parameters

frameNumber
picType	Specify frame type (I-Frame, P-Frame or B-Frame).

releaseBitStream()

virtual void cv::cudacodec::EncoderCallBack::releaseBitStream ( unsigned char *  data, int  size  )

pure virtual

Callback function to signal that the encoded bitstream is ready to be written to file.
