Detailed Description

This structure describes media stream information. Each media stream corresponds to one "m=" line in SDP session descriptor, and it has its own RTP/RTCP socket pair.

Field Documentation

pjmedia_type pjmedia_stream_info::type

Media type (audio, video)

pjmedia_tp_proto pjmedia_stream_info::proto

Transport protocol (RTP/AVP, etc.)

pjmedia_dir pjmedia_stream_info::dir

Media direction.

pj_sockaddr pjmedia_stream_info::rem_addr

Remote RTP address

pj_sockaddr pjmedia_stream_info::rem_rtcp

Optional remote RTCP address. If sin_family is zero, the RTP address will be calculated from RTP.

pjmedia_codec_info pjmedia_stream_info::fmt

Incoming codec format info.

pjmedia_codec_param* pjmedia_stream_info::param

Optional codec param.

unsigned pjmedia_stream_info::tx_pt

Outgoing codec paylaod type.

unsigned pjmedia_stream_info::tx_maxptime

Outgoing codec max ptime.

int pjmedia_stream_info::tx_event_pt

Outgoing pt for telephone-events.

int pjmedia_stream_info::rx_event_pt

Incoming pt for telephone-events.

pj_uint32_t pjmedia_stream_info::ssrc

RTP SSRC.

pj_uint32_t pjmedia_stream_info::rtp_ts

Initial RTP timestamp.

pj_uint16_t pjmedia_stream_info::rtp_seq

Initial RTP sequence number.

pj_uint8_t pjmedia_stream_info::rtp_seq_ts_set

Bitmask flags if initial RTP sequence and/or timestamp for sender are set. bit 0/LSB : sequence flag bit 1 : timestamp flag

int pjmedia_stream_info::jb_init

Jitter buffer init delay in msec. (-1 for default).

int pjmedia_stream_info::jb_min_pre

Jitter buffer minimum prefetch delay in msec (-1 for default).

int pjmedia_stream_info::jb_max_pre

Jitter buffer maximum prefetch delay in msec (-1 for default).

int pjmedia_stream_info::jb_max

Jitter buffer max delay in msec.

pj_bool_t pjmedia_stream_info::use_ka

Stream keep-alive and NAT hole punch (see PJMEDIA_STREAM_ENABLE_KA) is enabled?

pj_bool_t pjmedia_stream_info::rtcp_sdes_bye_disabled

Disable automatic sending of RTCP SDES and BYE.
