Inheritance diagram for IncomingRTPPkt:
Public Member Functions | |
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. | |
bool | checkZrtpChecksum (bool check) |
Recompute and check ZRTP checksum. |
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.
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().
block | pointer to the buffer the whole packet is stored in. | |
len | length of the whole packet, expressed in octets. |
IncomingRTPPkt::~IncomingRTPPkt | ( | ) | [inline] |
bool IncomingRTPPkt::checkZrtpChecksum | ( | bool | check | ) |
Recompute and check ZRTP checksum.
If the check parameter is true then this method recomputes the ZRTP checksum and compares it with the checksum conatined in the packet. If the parameter is set to false the method only adjusts the length of the data.
check | if true recompute and check, otherwise adjust length of packet data only. |
true
if check is ok or only length was adjusted. If check fails returns false
uint32 IncomingRTPPkt::getSSRC | ( | ) | const [inline] |
Get synchronization source numeric identifier.
bool IncomingRTPPkt::isHeaderValid | ( | ) | [inline] |
Get validity of this packet.
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.
pcc | Pointer to SRTP CryptoContext. |
