Member Function Documentation

PBoolean OpalPluginVideoTranscoder::ConvertFrames ( const RTP_DataFrame src,
RTP_DataFrameList &  dstList 
) [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.

PBoolean OpalPluginVideoTranscoder::ExecuteCommand ( const OpalMediaCommand command  ) 

Reimplemented from OpalPluginTranscoder.

virtual void OpalPluginVideoTranscoder::GetStatistics ( OpalMediaStatistics statistics  )  const [virtual]

Reimplemented from OpalVideoTranscoder.

bool OpalPluginVideoTranscoder::UpdateMediaFormats ( const OpalMediaFormat input,
const OpalMediaFormat output 
) [virtual]

Update the input and output media formats. This can be used to adjust the parameters of a codec at run time. Note you cannot change the basic media format, eg change GSM0610 to G.711, only options for that format, eg 6k3 mode to 5k3 mode in G.723.1. If the formats are different then a OpalMediaFormat::Merge() is performed.

If a format is empty (invalid) it is ignored and does not update the internal variable. In this way only the input or output side can be updated.

The default behaviour updates the inputMediaFormat and outputMediaFormat member variables.

Reimplemented from OpalVideoTranscoder.
