Method Detail

acquireBitStream

@Cast(value="uchar*")
public BytePointer acquireBitStream(IntPointer bufferSize)

\brief 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.

acquireBitStream

@Cast(value="uchar*")
public ByteBuffer acquireBitStream(IntBuffer bufferSize)

acquireBitStream

@Cast(value="uchar*")
public byte[] acquireBitStream(int[] bufferSize)

releaseBitStream

public void releaseBitStream(@Cast(value="unsigned char*")
                             BytePointer data,
                             int size)

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

releaseBitStream

public void releaseBitStream(@Cast(value="unsigned char*")
                             ByteBuffer data,
                             int size)

releaseBitStream

public void releaseBitStream(@Cast(value="unsigned char*")
                             byte[] data,
                             int size)

onBeginFrame

public void onBeginFrame(int frameNumber,
                         @Cast(value="cv::cudacodec::EncoderCallBack::PicType")
                         int picType)

\brief 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

public void onEndFrame(int frameNumber,
                       @Cast(value="cv::cudacodec::EncoderCallBack::PicType")
                       int picType)

\brief 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).
