The events defined in res/res_pjsip/pjsip_manager.xml were done by hand because the XML was extracted from the C source file relatively recently. Two bugs were fixed along the way... * The get_documentation awk script was exiting after it processed the first DOCUMENTATION block it found in a file. We have at least 1 source file with multiple DOCUMENTATION blocks so only the first one in them was being processed. The awk script was changed to continue searching rather than exiting after the first block. * Fixing the awk script revealed an issue in logger.c where the third DOCUMENTATION block contained a XML fragment that consisted only of a managerEventInstance element that wasn't wrapped in a managerEvent element. Since logger_doc.xml already existed, the remaining fragments in logger.c were moved to it and properly organized.	3 months ago

Sean Bright	ca931c9436	app.c: Allow ampersands in playback lists to be escaped. ... Any function or application that accepts a `&`-separated list of filenames can now include a literal `&` in a filename by wrapping the entire filename in single quotes, e.g.: ``` exten = _X.,n,Playback('https://example.com/sound.cgi?a=b&c=d'&hello-world) ``` Fixes #172 UpgradeNote: Ampersands in URLs passed to the `Playback()`, `Background()`, `SpeechBackground()`, `Read()`, `Authenticate()`, or `Queue()` applications as filename arguments can now be escaped by single quoting the filename. Additionally, this is also possible when using the `CONFBRIDGE` dialplan function, or configuring various features in `confbridge.conf` and `queues.conf`.	1 year ago

Naveen Albert	2843e5678d	app_confbridge: Always set minimum video update interval. ... Currently, if multiple video-enabled ConfBridges are conferenced together, we immediately get into a scenario where an infinite sequence of video updates fills up the taskprocessor queue and causes memory consumption to climb unabated until Asterisk is killed. This is due to the core bridging mechanism that provides video updates (softmix_bridge_write_control in bridge_softmix.c) continously updating all the channels in the bridge with video updates. The logic to do so in the core is that the video updates should be provided if the video_update_discard property for the bridge is 0, or if enough time has elapsed since the last video update. Thus, we already have a safeguard built in to ensure the scenario described above does not happen. Currently, however, this safeguard is not being adequately ensured. In app_confbridge, the video_update_discard property defaults to 2000, which is a healthy value that should completely prevent this issue. However, this value is only set onto the bridge in the SFU video mode. This leaves video modes such as follow_talker completely vulnerable, since video_update_discard will actually be 0, since the default or set value was never applied. As a result, the core bridging mechanism will always try to provide video updates regardless of when the last one was sent. To prevent this issue from happening, we now always set the video_update_discard property on the bridge with the value from the bridge profile. The app_confbridge defaults will thus ensure that infinite video updates no longer happen in any video mode. ASTERISK-29907 #close Change-Id: I4accb2536ac62797950468e9930f12ef7dd486b2	3 years ago

George Joseph	f10c7b6eeb	app_confbridge: Use bridge join hook to send join and leave events ... The first attempt at publishing confbridge events to participants involved publishing them at the same time stasis events were created. This caused issues with bridge and channel locks. The second attempt involved publishing them when the stasis events were received by the code that published the confbridge AMI events. This caused timing issues because, depending on resources available, the event could be received before channels actually joined the bridge and would therefore fail to send messages to the participant. This attempt reverts to the original mechanism with one exception. The join and leave events are published via bridge join and leave hooks. This guarantees the states of the channels and bridge and provides deterministic timing for event publishing. Change-Id: I2660074f8a30a5224cb953d5e047ee84484a9036	7 years ago
Robert Mordec	9d3f3a4b0a	app_confbridge: Bridge and announcers not removed if conference ends quickly ... If a conference is ended very quickly after it was created (i.e., the first user immediately hangs up) then the conference bridge and announcer channels are not removed. When a conference is created, the push_announcer() function is added to the playback queue task processor and the conference object reference is bumped. If a conference is ended while the push_announcer() function is still going then the ao2_cleanup(conference) at the end of push_announcer() will call the destructor function - destroy_conference_bridge(). The destroy_conference_bridge() function will then add the hangup_playback() task to the playback queue and will wait for it to end. Since it is already a current task of the playback queue it will wait forever. This patch makes the conference thread call push_announcer() directly. This way the conference object reference bump is not needed. Since the playback queue task processor is only used by the conference thread itself, there is no danger of trying to play announcements before the announcer is pushed to the bridge.

George Joseph	5f12e2bd07	app_confbridge: Move participant info code to confbridge_manager. ... With the participant info code in app_confbridge, we were still in the process of adding the channel to the bridge when trying to send an in-dialog MESSAGE. This caused 2 threads to grab the channel blocking flag at the same time. To mitigate this, the participant info code was moved to confbridge_manager so it runs after all channel/bridge actions have finished. Change-Id: I228806ac153074f45e0b35d5236166e92e132abd	7 years ago
George Joseph	e7a7506f9c	app_confbridge: Enable sending events to participants ... ConfBridge can now send events to participants via in-dialog MESSAGEs. All current Confbridge events are supported, such as ConfbridgeJoin, ConfbridgeLeave, etc. In addition to those events, a new event ConfbridgeWelcome has been added that will send a list of all current participants to a new participant. For all but the ConfbridgeWelcome event, the JSON message contains information about the bridge, such as its id and name, and information about the channel that triggered the event such as channel name, callerid info, mute status, and the MSID labels for their audio and video tracks. You can use the labels to correlate callerid and mute status to specific video elements in a webrtc client. To control this behavior, the following options have been added to confbridge.conf: bridge_profile/enable_events: This must be enabled on any bridge where events are desired. user_profile/send_events: This must be set for a user profile to send events. Different user profiles connected to the same bridge can have different settings. This allows admins to get events but not normal users for instance. user_profile/echo_events: In some cases, you might not want the user triggering the event to get the event sent back to them. To prevent it, set this to false. A change was also made to res_pjsip_sdp_rtp to save the generated msid to the stream so it can be re-used. This allows participant A's video stream to appear as the same label to all other participants. Change-Id: I26420aa9f101f0b2387dc9e2fd10733197f1318e	7 years ago
William McCall	a7f4121238	app_confbridge: Add talking indicator for ConfBridgeList AMI response ...

Joshua Colp	8de3fa2b56	bridge_softmix / app_confbridge: Add support for REMB combining. ... This change adds the ability for multiple REMB reports in bridge_softmix to be combined according to a configured behavior into a single report. This single report is sent back to the sender of video, which adjusts the encoding bitrate to be at or below the bitrate of the report. The available behaviors are: lowest, highest, and average. Lowest uses the lowest received bitrate. Highest uses the highest received bitrate. Average goes through the received bitrates adding them to the previous average and creates a new average. Other behaviors can be added in the future and the existing average one may be adjusted, but this provides the foundation to do so. Support for configuring which behavior to use has been added to app_confbridge. ASTERISK-27804 Change-Id: I9eafe4e7c1f72d67074a8d6acb26bfcf19322b66	7 years ago

Joshua Colp	680c491a62	bridge_softmix / res_rtp_asterisk: Fix packet loss and renegotiation issues. ... This change does a few things to improve packet loss and renegotiation: 1. On outgoing RTP streams we will now properly reflect out of order packets and packet loss in the sequence number. This allows the remote jitterbuffer to better reorder things. 2. Video updates can now be discarded for a period of time after one has been sent to prevent flooding of clients. 3. For declined and removed streams we will now release any media session resources associated with them. This was not previously done and caused an issue where old state was being used for a new stream. 4. RTP bundling was not actually removing bundled RTP instances from the parent. This has been resolved by removing based on the RTP instance itself and not the SSRC. 5. The code did not properly handle explicitly unbundling an RTP instance from its parent. This now works as expected. ASTERISK-27143 Change-Id: Ibd91362f0e4990b6129638e712bc8adf0899fd45	8 years ago

That is, when the bridge is created, if SFU mode is enabled, then the video mode gets set to SFU and cannot be changed. Future improvements may allow for a hybrid experience (e.g. forward multiple video streams, specifically those of the most recent talkers), but for this addition, no such capability is present.

Robert Mordec	36e90952ec	app_confbridge: Race between removing and playing name recording while leaving ... When user leaves a conference, its channel calls async_play_sound_file() in order to play the name announcement and then unlinks the sound file. The async_play_sound_file() function adds a task to conference playback queue, which then runs playback_common() function in a different thread.

Mark Michelson	ac02bbd9a0	ConfBridge: Make some announcements asynchronous. ... Confbridge announcements tend to block a channel while they are being played. In some circumstances, this is warranted since you want that particular channel not to hear the announcement (Example: "John Doe has entered the conference"). For others it makes less sense. This change first introduces methods for playing sounds asynchronously into the conference. This is very similar to how synchronous sounds are played, except the channel initiating the playback does not wait for the sound to complete before moving on. Asynchronous announcements are used for two circumstances: * Sounds played for a user after they have left the bridge * Sounds that play first to a single user and then the rest of the conference (if the channel and conference use the same language) ASTERISK-26289 #close Reported by Mark Michelson Change-Id: Ie486bb3de1646d50894489030326a423e594ab0a	9 years ago
