Properties

address → Pointer<T>

Available on T, provided by the StructAddress extension

The memory address of the underlying data.
no setter
audio_frame_ptime ↔ int
Specify audio frame ptime. The value here will affect the samples per frame of both the sound device and the conference bridge. Specifying lower ptime will normally reduce the latency.
getter/setter pair
channel_count ↔ int
Channel count be applied when opening the sound device and conference bridge.
getter/setter pair
clock_rate ↔ int
Clock rate to be applied to the conference bridge. If value is zero, default clock rate will be used (PJSUA_DEFAULT_CLOCK_RATE, which by default is 16KHz).
getter/setter pair
ec_options ↔ int
Echo canceller options (see #pjmedia_echo_create()). Specify PJMEDIA_ECHO_USE_SW_ECHO here if application wishes to use software echo canceller instead of device EC.
getter/setter pair
ec_tail_len ↔ int
Echo canceller tail length, in miliseconds.
getter/setter pair
enable_ice ↔ int
Enable ICE
getter/setter pair
enable_turn ↔ int
Enable TURN relay candidate in ICE.
getter/setter pair
has_ioqueue ↔ int
Specify whether the media manager should manage its own ioqueue for the RTP/RTCP sockets. If yes, ioqueue will be created and at least one worker thread will be created too. If no, the RTP/RTCP sockets will share the same ioqueue as SIP sockets, and no worker thread is needed.
getter/setter pair
hashCode → int
The hash code for this object.
no setterinherited
ice_always_update ↔ int
Send re-INVITE/UPDATE every after ICE connectivity check regardless the default ICE transport address is changed or not. When this is set to PJ_FALSE, re-INVITE/UPDATE will be sent only when the default ICE transport address is changed.
getter/setter pair
ice_max_host_cands ↔ int
Set the maximum number of host candidates.
getter/setter pair
ice_no_rtcp ↔ int
Disable RTCP component.
getter/setter pair
ice_opt ↔ pj_ice_sess_options
ICE session options.
getter/setter pair
ilbc_mode ↔ int
iLBC mode (20 or 30).
getter/setter pair
jb_discard_algo ↔ int
Set the algorithm the jitter buffer uses to discard frames in order to adjust the latency.
getter/setter pair
jb_init ↔ int
Jitter buffer initial prefetch delay in msec. The value must be between jb_min_pre and jb_max_pre below. If the value is 0, prefetching will be disabled.
getter/setter pair
jb_max ↔ int
Set maximum delay that can be accomodated by the jitter buffer msec.
getter/setter pair
jb_max_pre ↔ int
Jitter buffer maximum prefetch delay in msec.
getter/setter pair
jb_min_pre ↔ int
Jitter buffer minimum prefetch delay in msec.
getter/setter pair
max_media_ports ↔ int
Specify maximum number of media ports to be created in the conference bridge. Since all media terminate in the bridge (calls, file player, file recorder, etc), the value must be large enough to support all of them. However, the larger the value, the more computations are performed.
getter/setter pair
no_rtcp_sdes_bye ↔ int
Omit RTCP SDES and BYE in outgoing RTCP packet, this setting will be applied for both audio and video streams. Note that, when RTCP SDES and BYE are set to be omitted, RTCP SDES will still be sent once when the stream starts/stops and RTCP BYE will be sent once when the stream stops.
getter/setter pair
no_smart_media_update ↔ int
Disable smart media update (ticket #1568). The smart media update will check for any changes in the media properties after a successful SDP negotiation and the media will only be reinitialized when any change is found. When it is disabled, media streams will always be reinitialized after a successful SDP negotiation.
getter/setter pair
no_vad ↔ int
Disable VAD?
getter/setter pair
on_aud_prev_play_frame ↔ Pointer<NativeFunction<Void Function(Pointer<pjmedia_frame> frame)>>
Optional callback for audio frame preview right before queued to the speaker. Notes:
getter/setter pair
on_aud_prev_rec_frame ↔ Pointer<NativeFunction<Void Function(Pointer<pjmedia_frame> frame)>>
Optional callback for audio frame preview recorded from the microphone before being processed by any media component such as software echo canceller. Notes:
getter/setter pair
ptime ↔ int
Specify default codec ptime.
getter/setter pair
quality ↔ int
Media quality, 0-10, according to this table: 5-10: resampling use large filter, 3-4: resampling use small filter, 1-2: resampling use linear. The media quality also sets speex codec quality/complexity to the number.
getter/setter pair
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
rx_drop_pct ↔ int
Percentage of RTP packet to drop in RX direction (to simulate packet lost).
getter/setter pair
snd_auto_close_time ↔ int
Specify idle time of sound device before it is automatically closed, in seconds. Use value -1 to disable the auto-close feature of sound device
getter/setter pair
snd_clock_rate ↔ int
Clock rate to be applied when opening the sound device. If value is zero, conference bridge clock rate will be used.
getter/setter pair
snd_play_latency ↔ int
Audio playback buffer length, in milliseconds.
getter/setter pair
snd_rec_latency ↔ int
Audio capture buffer length, in milliseconds.
getter/setter pair
thread_cnt ↔ int
Specify the number of worker threads to handle incoming RTP packets. A value of one is recommended for most applications.
getter/setter pair
turn_auth_cred ↔ pj_stun_auth_cred
Specify the credential to authenticate with the TURN server.
getter/setter pair
turn_conn_type ↔ int
Specify the connection type to be used to the TURN server. Valid values are PJ_TURN_TP_UDP, PJ_TURN_TP_TCP or PJ_TURN_TP_TLS.
getter/setter pair
turn_server ↔ pj_str_t
Specify TURN domain name or host name, in in "DOMAIN:PORT" or "HOST:PORT" format.
getter/setter pair
turn_tls_setting ↔ pj_turn_sock_tls_cfg
This specifies TLS settings for TLS transport. It is only be used when this TLS is used to connect to the TURN server.
getter/setter pair
tx_drop_pct ↔ int
Percentage of RTP packet to drop in TX direction (to simulate packet lost).
getter/setter pair
vid_preview_enable_native ↔ int
Specify whether built-in/native preview should be used if available. In some systems, video input devices have built-in capability to show preview window of the device. Using this built-in preview is preferable as it consumes less CPU power. If built-in preview is not available, the library will perform software rendering of the input. If this field is set to PJ_FALSE, software preview will always be used.
getter/setter pair
