           Get synchronization source numeric identifier.
       int32 unprotect (CryptoContext *pcc)
           Unprotect a received packet.
       bool operator== (const IncomingRTPPkt &p) const
           Two incoming packets are equal if they come from sources with the
           same SSRC and have the same sequence number.
       bool operator!= (const IncomingRTPPkt &p) const
           Two incoming packets are not equal if they come from different
           sources or have different sequence numbers.

Detailed Description

       RTP packets received from other participants.

       This class is intented to construct a packet object just after every
       packet is received by the scheduled queue, so that they are processed
       in an understandable and format independent manner inside the stack.

Constructor & Destructor Documentation

   IncomingRTPPkt::IncomingRTPPkt (const unsigned char * block, size_t len)
       Build an RTP packet object from a data buffer. This constructor first
       performs a generic RTP data packet header check, whose result can be
       checked via isHeaderValid().

       Parameters:
           block pointer to the buffer the whole packet is stored in.
           len length of the whole packet, expressed in octets.

       Note:
           If check fails, the packet object is incomplete. checking
           isHeaderValid() is recommended before using a new RTPPacket object.

Member Function Documentation

   uint32 IncomingRTPPkt::getSSRC () const [inline]
       Get synchronization source numeric identifier. Returns:
           32-bits Synchronization SouRCe numeric identifier, in host order.

   bool IncomingRTPPkt::isHeaderValid () [inline]
       Get validity of this packet. Returns:
           whether the header check performed at construction time ended
           successfully.

   bool IncomingRTPPkt::operator!= (const IncomingRTPPkt & p) const [inline]
       Two incoming packets are not equal if they come from different sources
       or have different sequence numbers.

   bool IncomingRTPPkt::operator== (const IncomingRTPPkt & p) const [inline]
       Two incoming packets are equal if they come from sources with the same
       SSRC and have the same sequence number.

   int32 IncomingRTPPkt::unprotect (CryptoContext * pcc)
       Unprotect a received packet. Perform SRTP processing on this packet.

       Parameters:
           pcc Pointer to SRTP CryptoContext.

       Returns:
           one if no errors, -1 if authentication failed, -2 if replay check
           failed
