Constructor & Destructor Documentation

OpalPCM16SilenceDetector::OpalPCM16SilenceDetector ( const Params &  newParam )

inline

Construct new silence detector for PCM-16/8000

Parameters

newParam

New parameters for silence detector

Member Function Documentation

virtual unsigned OpalPCM16SilenceDetector::GetAverageSignalLevel ( const BYTE *  buffer, PINDEX  size  )

virtual

Get the average signal level in the stream. This is called from within the silence detection algorithm to calculate the average signal level of the last data frame read from the stream.

The default behaviour returns UINT_MAX which indicates that the average signal has no meaning for the stream.

Parameters

buffer	RTP payload being detected
size	Size of payload buffer

Implements OpalSilenceDetector.
