Net::RTP(3)	      User Contributed Perl Documentation	   Net::RTP(3)

NAME
       Net::RTP	- Send and receive RTP packets (RFC3550)

SYNOPSIS
	 use Net::RTP;

	 my $rtp = new Net::RTP( LocalPort=>5170, LocalAddr=>'233.122.227.171' );

	 my $packet = $rtp->recv();
	 print "Payload	type: ".$packet->payload_type()."\n";

DESCRIPTION
       The "Net::RTP" module subclasses	IO::Socket::Multicast6 to enable you
       to manipulate multicast groups. The multicast additions are optional,
       so you may also send and	recieve	unicast	packets.

       $rtp = new Net::RTP( [LocalAdrr=>$addr, LocalPort=>$port,...] )
	   The new() method is the constructor for the Net::RTP	class.	It
	   takes the same arguments as IO::Socket::INET, however the Proto
	   argument defaults to	"udp", which is	more appropriate for RTP.

	   The Net::RTP	super-class used will depend on	what is	available on
	   your	system it will try and use one of the following	(in order of
	   preference) :

		   IO::Socket::Multicast6 (IPv4	and IPv6 unicast and multicast)
		   IO::Socket::Multicast (IPv4 unicast and multicast)
		   IO::Socket::INET6 (IPv4 and IPv6 unicast)
		   IO::Socket::INET (IPv4 unicast)

	   If LocalAddr	looks like a multicast address,	then Net::RTP will
	   automatically try and join that multicast group for you.

       my $packet = $rtp->recv(	[$size]	)
	   Blocks and waits for	an RTP packet to arrive	on the UDP socket.
	   The read $size defaults to 2048 which is usually big	enough to read
	   an entire RTP packet	(as it is advisable that packets are less than
	   the Ethernet	MTU).

	   Returns a "Net::RTP::Packet"	object or undef	if there is a problem.

       $rtp->send( $packet )
	   Send	a Net::RTP::Packet from	out of the RTP socket.	The PeerPort
	   and PeerAddr	should be defined in order to send packets.  Returns
	   the number of bytes sent, or	the undefined value if there is	an
	   error.

       $rtp->superclass()
	   Returns the name of the super-class that Net::RTP chose to use.
