Detailed Description

RTP Data Packet.

The RTP Header exists for all RTP packets, it contains a payload type, timestamp and a sequence number for packet reordering.

Different RTP Data Packet types have their own sub-classes for accessing the data portion of the packet.

The data is stored in a QByteArray which is a reference counted shared data container, so an RTPDataPacket can be assigned to a subclass efficiently.
