void OpalRFC4175Encoder::AddNewDstFrame ( )

protected

bool OpalRFC4175Encoder::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.

Implemented in Opal_RGB24_to_RFC4175RGB, and Opal_YUV420P_to_RFC4175YCbCr420.
