Member Function Documentation

virtual PBoolean Opal_G711_PCM::Convert ( const RTP_DataFrame &  input, RTP_DataFrame &  output  )

virtual

Convert the data from one format to another. This function takes the input data as a RTP_DataFrame and converts it to its output format, placing it into the RTP_DataFrame provided.

Returns false if the conversion fails.

Parameters

input	Input data
output	Output data

Reimplemented from OpalStreamedTranscoder.
