Member Function Documentation

BuildCompFrame()

HRESULT GrayLib::cVideoFSRateController::BuildCompFrame ( TIMESYS_t  tWhenLast, const void *&  rpCompRet, size_t &  rnSizeRet  )

overridevirtual

based on cAVRateController Build a (sort of) key frame from a certain point in time.

• tWhenLast = 0 = full key frame.

  Returns

  Number of blocks changed.

Implements GrayLib::cAVRateController.

OnFrame()

HRESULT GrayLib::cVideoFSRateController::OnFrame ( const cAVHeaderFrame &  head, const void *  pData, size_t  nSizeData  )

overridevirtual

cAVSink in cAVRateController Add a new frame to the cache.

Reimplemented from GrayLib::cAVSink.

OnHeaderStream()

HRESULT GrayLib::cVideoFSRateController::OnHeaderStream ( const cAVHeaderStream &  head, const void *  pForm, size_t  nSizeForm  )

overridevirtual

cAVSink in cAVRateController

Reimplemented from GrayLib::cAVSink.
