There may be other bridges may not need to force relay traffic on
firefox as @prlanzarin pointed out. So set the default to a
configuration that works out of the box but leave other choices for the
operator.
The option is moved from kurento namespace to media next to the general
forceRelay option.
Firefox has a buggy ICE implementation and needs WebRTC media traffic to
be routed through a turn server to work reliably with mediasoup.
Use the information fetched by the STUN API to determine if the operator
has configured a turn server. If there is one force firefox to use it.
Closes#16164
When BBB is run as a single node or in a scaleout setup with a cluster
proxy in front (see https://docs.bigbluebutton.org/admin/clusterproxy.html) it
is useful to store client settings in browser localStorage instead of
sessionStorage. If localStorage is configured then the client will keep seetings
like notifications for user joining, chat etc across meetings.
It is not advisable to set the setting to `local` in a setup of multiple BBB
nodes without a cluster proxy in front of it because this would lead to
unexpected behaviour at users. The browser would store settings for each server
and for users it would look like BBB is sometimes store the settings and
sometimes not.
It adds the new setting
```yaml
public:
app:
userSettingsStorage: (session|local)
```
Currently, collection cleanup code is only run when an added event
is received from the server. Where that fails is in scenarios where
a server-side collection turns empty while an affected users is
disconnected - and then reconnects. There's no removed (or updated)
event so no cleanup code is run and you have stale data.
This commit guarantees a stale data check is run whenever a subscription
is established again. The `added` check was also maintained, although
I'm not too sure anymore it's is still needed. That may need to be
revisited.
There are some situations where previously set deviceIds (
local/session storage) may become stale. This causes an unexpected
behavior where audio is temporarily borked until the user clears their
local storage.
This issue has been seen more recently on Safari endpoints when switching
back-and-forth breakout rooms in environments running under iframes.
Also seen randomly on endpoints with virtual input devices.
This centralizes audio gUM calling into a single method that retries the
gUM procedure without pre-set deviceIds only if the initial call fails
due with an OverconstrainedError - hopefully circumventing the issue.
