Function Documentation

register_tap_listener_rtpstream()

void register_tap_listener_rtpstream	(	rtpstream_tapinfo_t *	tapinfo,
		const char *	fstring,
		rtpstream_tap_error_cb	tap_error
	)

Registers the rtp_streams tap listener (if not already done). From that point on, the RTP streams list will be updated with every redissection. This function is also the entry point for the initialization routine of the tap system. So whenever rtp_stream.c is added to the list of WIRESHARK_TAP_SRCs, the tap will be registered on startup. If not, it will be registered on demand by the rtp_streams and rtp_analysis functions that need it.

remove_tap_listener_rtpstream()

void remove_tap_listener_rtpstream

(

rtpstream_tapinfo_t *

tapinfo

)

Removes the rtp_streams tap listener (if not already done) From that point on, the RTP streams list won't be updated any more.

rtpstream_info_analyse_init()

void rtpstream_info_analyse_init	(	rtpstream_info_t *	stream_info,
		const packet_info *	pinfo,
		const struct _rtp_info *	rtpinfo
	)

Init analyse counters in rtpstream_info_t from pinfo

rtpstream_info_analyse_process()

void rtpstream_info_analyse_process	(	rtpstream_info_t *	stream_info,
		const packet_info *	pinfo,
		const struct _rtp_info *	rtpinfo
	)

Update analyse counters in rtpstream_info_t from pinfo

Free rtpstream_info_calc_t structure (internal items)

rtpstream_info_calculate()

void rtpstream_info_calculate	(	const rtpstream_info_t *	strinfo,

	)

Returns

true if the

rtpstream_info_multihash_destroy_value()

rtpstream_is_payload_used()

bool rtpstream_is_payload_used	(	const rtpstream_info_t *	stream_info,
		const uint8_t	payload_type
	)
