Function Documentation

static int rtp_hdr_val_chk	(	rtp_pkt *	pkt,
		int	len
	)			[static]

Checks if the RTP header is valid for the given packet

Parameters:

	pkt	Pointer to the packet
	len	Length of the packet

Returns:

0 if the header is valid, 1 otherwise

static void rtp_init_seq	(	rtp_ssrc *	stm_src,
		uint16_t	seq
	)			[static]

Initializes informations about sequence numbers for the given source using the given seq number as the first one. And appends the source to the list of active sources for the given RTP session.

Parameters:

	stm_src	The source for which to initialize the sequence numbers informations
	seq	The first sequence number

void rtp_update_seq	(	rtp_ssrc *	stm_src,
		uint16_t	seq
	)

Updates informations about sequence numbers for the given source. Sets max sequence number, initializes the sequence numbers and calls rtp_init if it is the first received sequence number, checks for misordered packets/jumps

Parameters:

	stm_src	The source for which to update the sequence numbers informations
	seq	The sequence number to analyze
