Detailed Description

A peer associated RTP socket pair for physically connected peer hosts.

This has no RTCP and assumes the receiver is connected to a known transmitter, hence no "foreign" packets will arrive.

Author: David Sugar RTP peer host over UDP.

Member Enumeration Documentation

enum RTPDataQueue::Tos

inherited

rtp.h cc++/rtp.h

Type of network service the application uses.

If the application uses enhanced network service, for instance Integrated Services or Differentiated Services, it has not to ensure fair competition with TCP, provided that the requested service is actually being delivered. Whenever the application uses best-effort service or the requested enhanced service is not actually being delivered, it has to ensure fair competition with TCP. By default, best-effot is assumed.

Note: Although not required, RTP packets are always sent on top of UDP segments. No other underlying transport protocol is supported at present.

Todo:: implement fair competition with tcp

Enumerator
tosBestEffort	Best-effort network service.

inlineprotectedinherited

Definition at line 522 of file oqueue.h.

uint32 RTPDataQueue::getCurrentTimestamp ( ) const

inherited

Get the timestamp that should be given for a packet whose payload sampling instant corresponds to the current system time.

The timestamp applications should provide for each packet represents the sampling instant of its payload and should not be a reading of the system clock. Nevertheless, the internal operation of the RTP stack relies on the accuracy of the provided timestamp, since several computations assume that there is a certain degree of correspondence between the timestamp and the system clock.

It is recommended that applications use this method in order to periodically adjust the RTP timestamp.

In particular, it is advisable getting the timestamp corresponding to the first sampling instant or any instant after a period of inactivity through a call to this method.

Applications should use the nominal sampling or any other value provided by the coder in order to compute the next timestamps with minimum computational requirement.

For instance, an application using an RTP profile that specifies a fixed sampling rate of 8 Khz with eight bits per sample, continuously transmitting audio blocks 80 octets long, would transmit 100 packets every second. Every packet would carry a timestamp 80 units greater than the previous one. So, the first timestamp would be obtained from this method, whereas the following ones would be computed adding 80 every time. Also the timestamp should be increased for every block whether it is put in the queue or dropped.

The aforementioned increment can be obtained from the RTPDataQueue::getTimestampIncrement() method rather than computing it by hand in the application.

Note: Frame based applications must follow a specific timestamping method, probably specified in a profile.; You should take into account that by default ccRTP assumes that the application begins sampling at the queue creation time. Moreover, the first sampling instant is assigned a "user visible" timestamp of 0, although the RTP stack will then add internally a ramdom offset unknown to the application. That is to say, the application may count samples from 0 in order to get the timestamp for the next packet, provided that the first sampling instant is the same as the queue creation time. Nevertheless, this simpler way of starting will not be as accurate as it would be if the application got at least the first timestamp through getCurrentTimestamp. We provide this option since ccRTP interface is evolving, but we admit that it is ugly, we could remove this option or even replace uint32 timestamps with a restrictively regulated object; suggestions are gladly welcomed

virtual bool IncomingDataQueue::onRTPPacketRecv ( IncomingRTPPkt & )

inlineprotectedvirtualinherited

A virtual function to support parsing of arriving packets to determine if they should be kept in the queue and to dispatch events.

A generic header validity check (as specified in RFC 1889) is performed on every incoming packet. If the generic check completes succesfully, this method is called before the packet is actually inserted into the reception queue.

May be used to perform additional validity checks or to do some application specific processing.

Parameters

-	packet just received.

Returns: true if packet is kept in the incoming packets queue.

This is used to create a data packet in the send queue.

Sometimes a "NULL" or empty packet will be used instead, and these are known as "silent" packets. "Silent" packets are used simply to "push" the scheduler along more accurately by giving the appearence that a next packet is waiting to be sent and to provide a valid timestamp for that packet.

Parameters

void IncomingDataQueue::setMinValidPacketSequence ( uint8 packets )

inlineinherited

When receiving packets from a new source, it may be convenient to reject a first few packets before we are really sure the source is valid.

This method sets how many data packets must be received in sequence before the source is considered valid and the stack starts to accept its packets.

Note: the default (see defaultMinValidPacketSequence()) value for this parameter is 0, so that no packets are rejected (data packets are accepted from the first one).; this validation is performed after the generic header validation and the additional validation done in onRTPPacketRecv().; if any valid RTCP packet is received from this source, it will be immediatly considered valid regardless of the number of sequential data packets received.

Parameters

packets number of sequential packet required
