I have growing concerns about gain node`s effect on audio quality the way it
was implemented, so I opted to fall back to HTMLMediaElement`s volume control
for the time being until we can gauge quality impacts properly later on
Add a new configuration flag enableVolumeControl, false by default while the
feature undergoes a field trial
- forceRelayOnFirefox: whether TURN/relay usage should be forced to work
around Firefox's lack of support for regular nomination when dealing with
ICE-litee peers (e.g.: mediasoup).
* See: https://bugzilla.mozilla.org/show_bug.cgi?id=1034964
- iOS endpoints are ignored from the trigger because _all_ iOS browsers
are either native WebKit or WKWebView based (so they shouldn't be affected)
Add the <ButtonEmoji/> to the webcam button. Now it
is possible to change the webcam settings and change
your settings without having to turn off sharing.
Modifies the <ButtonEmoji/> component so that it can
receive an onClick per props.
It is possible to disable this feat in the settings.yml
The idea is to run a loadbalancer node which maps each BBB node to a
path. That way each user gets only one gUM permission query for a
cluster. The loadbalancer node only serves the html5 client, each BBB
node will serve its own API and handle the websockets for freeswitch and
bbb-webrtc-sfu.
Configuring a cluster setup
===========================
* let bbb-lb.example.com be the loadbalancer node
* let bbb-01.eaxmple.com be a BBB node
Loadbalancer
------------
On the loadbalancer node add an nginx configuration similar to this one
for each BBB node:
```
location /bbb-01/html5client/ {
proxy_pass https://bbb-01.example.com/bbb-01/html5client/;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
}
```
BBB Node
--------
On the BBB node add the following options to
`/etc/bigbluebutton/bbb-web.properties`:
```
defaultHTML5ClientUrl=https://bbb-lb.example.com/bbb-01/html5client/join
presentationBaseURL=https://bbb-01.example.com/bigbluebutton/presentation
accessControlAllowOrigin=https://bbb-lb.example.com
```
Add the following options to `/etc/bigbluebutton/bbb-html5.yml`:
```
public:
app:
basename: '/bbb-01/html5client'
bbbWebBase: 'https://bbb-01.eaxmple.com/bigbluebutton'
learningDashboardBase: 'https://bbb-01.eaxmple.com/learning-dashboard'
media:
stunTurnServersFetchAddress: 'https://bbb-01.eaxmple.com/bigbluebutton/api/stuns'
sip_ws_host: 'bbb-01.eaxmple.com'
presentation:
uploadEndpoint: 'https://bbb-01.eaxmple.com/bigbluebutton/presentation/upload'
```
Create the following unit file overrides:
* `/etc/systemd/system/bbb-html5-frontend@.service.d/cluster.conf`
* `/etc/systemd/system/bbb-html5-backend@.service.d/cluster.conf`
with the following content:
```
[Service]
Environment=ROOT_URL=https://127.0.0.1/bbb-01/html5client
```
Change the nginx `$bbb_loadbalancer_node` variable to the name of the
load balancer node in `/etc/bigbluebutton/nginx/loadbalancer.nginx` to
allow CORS requests:
```
set $bbb_loadbalancer_node https://bbb-lb.example.com
```
Prepend the mount point of bbb-html5 in all location sections except
from the `location @html5client` section in
`/etc/bigbluebutton/nginx/bbb-html5.nginx`
```
location @html5client {
...
}
location /bbb-01/html5client/locales {
...
}
```
Previously we were using the same for listenonly, which for default
environments points to kurento, and didn't make any difference in media server
selection.
This could be problematic in those environments where meta param
for listeonly media server is set , though.
Fullaudio has now it's own meta param that can be passed through API:
"meta_media-server-fullaudio"
Adds prometheus client to collect html5 server metrics.
Only default Node.js metrics in this initial version.
Enable via configs in private.app.prometheus
ICE lite servers (eg mediasoup) dont need candidates signaled out-of-band; neither does KMS in certain scenarios
Disable their signaling saves us some ticks in bbb-webrtc-sfu and some bandwidth all around
Undefined by default means that the governing configuration is in bbb-webrtc-sfu
Also add some inline docs in settings.yml about the media server adapter configs
Changes (maybe not a complete list):
- Disable virtualbgs by default
- Move the virtualbg selector in video-preview to the side below the
profile selection
- Restore old video-preview sizes
- Add a wrapper class for MediaStreams (BBBVideoStream)
- Centralize virtualbg services and business logic code into BBBVideoStream
- Refactor and centralize virtualbg constant fetching
- Refactor and centralize virtualbg config fetching
- Organize virtualbg type definitions
- Remove added states in video-provider to prevent further bloat
- Remove added states in video-preview to prevent further bloat
- Lock virtual bg switching while video-preview itself is locked
- Add proper virtualbg error surfacing via toasts
- Refactor iOS availability detection to use centralized UA checker
- Avoid calling gUM when toggling virtualbgs on/off
- Make virtualbg video-list-item action a toggle instead of a
state-aware action
- Make virtualbg switching work in video-preview for cameras that are
already shared. Especially useful when there are multiple source
cameras, and will be important in the near future
- Add Derivative Work notices in files that are partially copied from
jitsi-meet
- Simplify track replacing in video-provider
- Split video-preview UI code for virtualbgs into a separate functional component
Remove parts of a previous connection monitor.
To add some context (as far as my memory goes) to the multiple connection
monitor features the product has, `stats` (currently named `connection status`)
was introduced at the Flash client back in ~2016. @fcecagno and I did it
as a BigBlueButton's Summit activity. Our work was squashed into a single
commit in 92554f8b3e :).
I'm not sure about the whole story behind `network information` (the late
connection monitor added to the HTML5 client) but I assume it should work
as a collector for a bunch of different connectivity monitors. I remember
when it was introduced but I don't know why it wasn't adopted. My best guess
would be because of some performance issues the `user list` had back then.
To follow on why `connection status` replaced `network information` at the
HTML5 client, when I did the `multiple webcams` feature I had to refactor
a big chunk of the `video provider` (#8374). Something that wasn't really
helping there was the adaptation of `stats` that was made to show local
feedback for each webcam connection. Although this feature wasn't being
used anymore, `network information` did rely on that to build up data. With
this monitor gone I assumed it was my responsibility to provide an alternative
so I promoted Mconf's port of the Flash `stats` monitor to BigBlueButton's
HTML5 client (#8579).
Well, that's my perspective on how things went for those features. If
anyone would like to correct me on something or add something else on
that history I would appreciate to know.
Add the `camera` icon in the user list for whoever is sharing,
in order to improve the understanding of who is sharing the webcam.
It is possible to enable/disable this indication in the settings.yml
This allows showing (or hiding) the option from users in the conference.
Default value is true (show this option to users).
Fixed some eslint warnings.
When listenOnlyMode=false, skipCheck=true and skipCheckOnJoin=true, the
audio tries to start a session more than one time, causing it to fail
at the first one (and reconnect after that).
Now we check if user is already connecting before trying to start a new
audio session.
Added some info in settings.yml for the options related to this commit
Closes#12190
Set paginationSorting to VOICE_ACTIVITY_LOCAL by default (audio floors -> alphabetical -> local stream).
Rationale: a more sensible default mode for pagination that actually works a bit better for the end user than
the previous mode (presenter -> alphabetical). Should reduce the need for page switching by focusing on
the ones that are actually active in the conference.
Video streams can be sorted by voice floor activity in the client according to FreeSWITCH´s floor events. The feature works together with pagination, essentially giving an Last-N like experience while not disrupting too much
Made video stream sorting extensible in a way. The sorting modes for pagination and unbounded can be configured in settings.yml and new sorting modes can be added to the stream sorting util under video-provider. Inline docs explain how to do that
Changed how the stream ID attribute from video-streams collection was passed to downstream components; we had an array map that was executed every change just to map stream to cameraId, which is bizarre. So I changed the cameraId usage in downstream components to be conformat with the collection attributes and shaved off the map where it wasnt needed
Add better selectors to video-list-item container´s VoiceUser fetch
- Removed the connection-status history from the user list's gear
icon and now is opened by the connection-status button. Moderators will
render the same modal as before and viewers will only have access to their
own data.
- Added data-savings shortcut at the connection-status modal.
- Added websocket round-trip time.
Modified the previous implementation of the whiteboard individual access to remove
multiple Collections dependency on this feature. Multi-user whiteboard is now an
array instead of a boolean value and most of the access control can be synchronized
and handled by akka-apps.
New config called paginationThreshold defines classes of page sizes that depend on the number of participants of a meeting
The rationale is pretty much the same as the cameraQualityThresholds, but the thresholds are users here and the ceilings are the page sizes
Moderators are able to send a message to the meeting's guest lobby. This new
event reaches bbb-web and is sent to the guest user with her/his status response
while polling. All guest users that are waiting for acceptance will be able to
read this message.
enableGuestLobbyMessage is disabled by default.
Both debounce or throttle could be used to prevent a spammer from
annoying the moderators.
With debounce, a spammer won't even be noticed by the mods, but
there won't be new notifications for legit guests during the spam.
With throttle, a spammer could still annoy the mods, we would only make
the interval between notifications bigger.
It is a tradeoff. An ideal solution would be preventing spamming from
the same user, but probably unnecessarily complex.
When managing Etherpad's pads, Meteor makes API calls to initiate the closed captions
and shared notes modules. The pad id was being mapped to a shorter id than the meeting
id because of a Etherpad lenght limitation.
Changed to something less guessable.
One of the main issues in 2.2.x problem reports currently in the wild in social media and in the bbb admin groups seems to be that people turn a couple of webcams on and the clients or the server already can't handle it any more. In most cases, enabling video-pagination for mobile devices and also cameraQualityThresholds already "solves" the problem and makes it possible for much more students to attend online-class as well as raise acceptance of using BBB instead of other commercial services.
Even after promoting these new settings for weeks, many BBB operators still don't know of them and are surprised and happy once they enable it.
This change contians rather high values so that admins see that these features exist, but typical use cases which might not want video-pagination enabled (typical 28people school class) are still not "annoyed".
* add param to force echo test when user joins audio after init
* fix UI stuck on connecting when userdata-bbb_auto_join_audio=false
* fix conditions for joinFullAudioImmediately and joinFullAudioEchoTest | remove old format
* remove extra param in getItem
* recover audioLocked | only set getEchoTest if doesnt exist
As explained in #11143, disabling audio filters is desired in some scenarios.
This basically adds an option for user to disable default constraints.
When user doesn't change this value in Settings > Application, the default
value for each audio constraints is retrieved from settings.yml.
When user changes this value in Settings > Application, audio
filters (AGC, Noise Supression and Echo Cancellation) are all set to
true/false, according to the value selected in the Settings GUI.
To start it simple, we decided to not to add a different setting in the GUI for
each audio contraint. This may be added in the future, though (perhaps in a
dedicated Audio Settings tab)
This is related to #4873
Changes to the current (v2.2) default configuration of the guest feature.
The ideal is to keep the simplified guest feature as default (`authenticatedGuests=false`)
but we also need to be in sync with Greenlight settings to make this happen.
Greenlight will have to re-add the `guest=true` param on user's join API call when ASK_MODERATOR
is set as guest's policy.

In some scenarios, there's no need for the browser to apply such audio filters. For example, when user's microphone already does audio filtering (echo cancellation, noise supression ...).
This commit doens't change the current behavior (filters still follow browser's default config): admins need to uncomment/set these values if disabling/enabling specific filters if desired.
This is related to #4873
Some browsers seem to (occasionally) not return the getUserMedia promise call and the
user gets stuck in this state unable to share her/his webcam.
Since enumerateDevices still works even on a gUM rejection this includes a racing
timeout that skips gUM. Configured at settings `gUMTimeout`.
Reproduced with Windows 10 Chrome 87.
Audio client logs already cover audio session progress the way we need.
This avoids keepAlive and other unnecessary messages to be logged in browser's console.
If setting is not present, default value is set to false.
This was added as an option (websocketKeepAliveInterval), which is the interval to send keep alive messages.
Setting websocketKeepAliveInterval to 0 disables the keep alive, producing the same old behavior.
This helps avoid websocket disconnection due to socket inactivity, preventing it to unnecessarily reconnect.
Also, sometimes reconnect fails and error 1005 is triggered.
Fixes problems reported in #10985.
Also reduces occurrences of error 1005.
Added new SFU broker for screen sharing
Removed kurento-extension entirely
Added inbound and outbound reconnection procedures
Improve UI responsiveness when sharing
Add reconnection UI states
Redo error handling
Refactor actions-bar screen share components. Make it smarter with less prop drilling and less re-rendering. Also more readable. Still work to do in that I think
Add a connection retry procedure for screen presenters when they are sharing; try a configurable amount of times when failure is triggered, with configurable min and max reconn timeouts and timeout increase factor
Make local preview attachment smarter
ADD PARTIAL SUPPORT FOR AUDIO SHARING VIA SCREEN SHARING WITH GET DISPLAY MEDIA, RECORDING STILL NOT SUPPORTED!!!
Fixed two occurrences where the tryGenerateIceCandidates workaround rejected without an error, which borked the callers error handling
Also put it behind a config flag. This workaround used to be important when Kurento didnt infer prflx candidates properly, but that`s no longer the case. With the flag, we can disable the workaround to see if there`s any visible regression and hopefully remove it down the road
This adds the possibility to configure the SIP Via header to plain WS to allow reverse proxying from WSS to WS, internally, to work around a bug in freeswitch where the WSS stack would get deadlocked due to a still unidentified bug in there that has to do with SSL termination
For some reason (still investigating), using turn/coturn on 443/tcp makes firefox's iceGathering process (during echo test) takes 12+ seconds (tested on webrtc's trickle page with multiple instances).
This was found when testing the current default (15s) on production with a private turn/coturn server on port 443/tcp. For default bbb setup (stun only), echo test still runs fast.
To avoid adding extra delay to iceGathering on this scenario (Firefox + turn on 443/tcp), i am just setting the default value back to the 5s (old default).
So , for those who wants to reduce the 1004 occurrences, increasing the iceGatheringTimeout could help (just be aware this adds delay on the mentioned scenario).
Added a default 'MEDIA' option: iceGatheringTimeout. This option allows admin to set a higher ICE gathering timeout, which can help when getting ICE errors during audio negotiation (eg 1004)
Default value set to 15s (current default is 5s).
This considerably changes the way we process audio signaling and start audio elements in user's browser.
We now avoid using AudioContext element for both microphone and listenonly calls, once it is unstable for some iOS devices (cracky audio, user stops hearing audio after a while).
Increased default value for listenOnlyCallTimeout: this avoids activating FreeSWITCH's fallback when ICE negotiation takes longer than 15sec (tested on DO).
Increased listenonly logs.
This fixes#8133#10388
This patch switchessing a somewhat more modern default for the camera
profiles by requesting 720p for the `high` and `hd` profiles like this.
