Macro Definition Documentation

RTPSTREAM_ID_EQUAL_NONE

#define RTPSTREAM_ID_EQUAL_NONE   0x0000

Check if two rtpstream_id_t are equal

• compare src_addr, dest_addr, src_port, dest_port
• compare other items when requested Note: ssrc is the only other item now, but it is expected it will be extended later

Typedef Documentation

rtpstream_id_t

typedef struct _rtpstream_id rtpstream_id_t

Defines an rtp stream identification

Function Documentation

pinfo_rtp_info_to_hash()

unsigned pinfo_rtp_info_to_hash	(	const packet_info *	pinfo,
		const struct _rtp_info *	rtp_info
	)

Get hash of rtpstream_id extracted from packet_info and _rtp_info

rtpstream_id_copy()

void rtpstream_id_copy	(	const rtpstream_id_t *	src,
		rtpstream_id_t *	dest
	)

Copy rtpstream_id_t structure

rtpstream_id_copy_pinfo()

void rtpstream_id_copy_pinfo	(	const packet_info *	pinfo,
		rtpstream_id_t *	dest,
		bool	swap_src_dst
	)

Deep copy addresses and ports from pinfo

rtpstream_id_copy_pinfo_shallow()

void rtpstream_id_copy_pinfo_shallow	(	const packet_info *	pinfo,
		rtpstream_id_t *	dest,
		bool	swap_src_dst
	)

Shallow copy addresses and ports from pinfo Do not call rtpstream_id_free if you use this function.

rtpstream_id_equal_pinfo()

bool rtpstream_id_equal_pinfo	(	const rtpstream_id_t *	id,
		const packet_info *	pinfo,
		bool	swap_src_dst
	)

Check if rtpstream_id_t is equal to pinfo

• compare src_addr, dest_addr, src_port, dest_port with pinfo
• if swap_src_dst is true, compare src to dst and vice versa

rtpstream_id_equal_pinfo_rtp_info()

bool rtpstream_id_equal_pinfo_rtp_info	(	const rtpstream_id_t *	id,
		const packet_info *	pinfo,
		const struct _rtp_info *	rtp_info
	)

Check if rtpstream_id_t is equal to pinfo and rtp_info

• compare src_addr, dest_addr, src_port, dest_port with pinfo
• compare ssrc with rtp_info

rtpstream_id_free()

void rtpstream_id_free

(

rtpstream_id_t *

id

)

Free memory allocated for id it releases address items only, do not release whole structure!

rtpstream_id_to_hash()

unsigned rtpstream_id_to_hash

(

const rtpstream_id_t *

id

)

Get hash of rtpstream_id
