IncomingRTPPkt - RTP packets received from other participants.

#include <rtppkt.h>

Inherits RTPPacket.


IncomingRTPPkt (const unsigned char *block, size_t len)
Build an RTP packet object from a data buffer. ~IncomingRTPPkt ()
bool isHeaderValid ()
Get validity of this packet. uint32 getSSRC () const
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.

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.

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.

Get synchronization source numeric identifier.

Returns:

32-bits Synchronization SouRCe numeric identifier, in host order.

Get validity of this packet.

Returns:

whether the header check performed at construction time ended successfully.

Two incoming packets are not equal if they come from different sources or have different sequence numbers.

Two incoming packets are equal if they come from sources with the same SSRC and have the same sequence number.

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
