Member Function Documentation

virtual PINDEX OpalRFC4175Decoder::BytesToPixels ( PINDEX  pixels) const
pure virtual
bool OpalRFC4175Decoder::ConvertFrames ( const RTP_DataFrame input,
RTP_DataFrameList &  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 (possibly) into multiple RTP_DataFrame objects.

The default behaviour makes sure the output list has only one element in it and calls the Convert() function.

Returns false if the conversion fails.

Reimplemented from OpalTranscoder.
