Tries to mitigate too-rapidly-switching camera profiles causing video freezes
due to encoder resets. Excluding constraints might not help a lot since
the thing that actually restarts the encoder is the bitrate change, but
they're not really important in the context of dynamic profiles.
We can't get rid of bitrate changes, though, since it's what does the actual
quality constraining.
The camera profile change debounce timer is 2.5s by default (which is
the same timer used for floor changes).
Also fixed an issue with camera profile backfiring due to badly defined peers
Set height to 720 in those profiles so that aspect ratio has a better chance to
be cohesive in all environments. Having only width set was causing certain
devices to output videos with non-standard ARs
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
