Constructor & Destructor Documentation

SpatialReductionAdaptor::SpatialReductionAdaptor (  VideoESInfo *  pESInfo,
u32 *  puiWidth,
u32 *  puiHeight,
u32  uiTargetBitrate,
u32  keyFrameInterval = 300,
MP4Decoder::meCoderType  codec = MP4Decoder::FFMPEG
) 
 

Constructor.

Parameters:
pESInfo Pointer to ESInfo object. Width, height, and bitrate information about the input stream will be fetched from this object.
puiWidth Desired width of the output stream.
puiHeight Desired height of the output stream.
uiTargetBitrate Target bitrate of the output stream.
