Member Function Documentation

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 OpalUncompVideoTranscoder.
