Member Function Documentation

virtual PINDEX OpalRFC4175Decoder::BytesToPixels ( PINDEX pixels ) const

pure virtual

Implemented in Opal_RFC4175RGB_to_RGB24, and Opal_RFC4175YCbCr420_to_YUV420P.

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.

virtual bool OpalRFC4175Decoder::DecodeFrames ( RTP_DataFrameList & output )

protectedpure virtual

Implemented in Opal_RFC4175RGB_to_RGB24, and Opal_RFC4175YCbCr420_to_YUV420P.

void OpalRFC4175Decoder::DecodeFramesAndSetFrameSize ( RTP_DataFrameList & output )

protected

virtual PINDEX OpalRFC4175Decoder::PixelsToBytes ( PINDEX pixels ) const

pure virtual

Implements OpalRFC4175Transcoder.

Implemented in Opal_RFC4175RGB_to_RGB24, and Opal_RFC4175YCbCr420_to_YUV420P.
