The RTPApplication is just a very simple sample for an application which uses RTP. It acts as a sender if the parameter fileName is set, and as a receiver if the parameter is empty.

Used in compound modules

Parameters

Name	Type	Default value	Description
commonName	string		the common name (CNAME) of this host
profileName	string		which rtp profile is to be used (usually RTPAVProfile)
bandwidth	double		bandwidth in bytes per second for this session
destinationAddress	string		destination address (the L3AddressResolver class is used to resolve the address)
portNumber	int		used port
fileName	string		fileName of file to be transmitted, "" means this system acts only as a receiver
payloadType	int		payload type of file to transmit
sessionEnterDelay	double		delay before starts a new session
transmissionStartDelay	double		delay before start transmission (related to "sender module created")
transmissionStopDelay	double		delay before stops transmission (related to "start transmission")
sessionLeaveDelay	double		delay before leave session (related to "file transmission finished/stopped" or "session entered" when fileName is "")
