SFU based audio is missing connection timers, which means the join
procedure can go on indefinitely in a couple of scenarios.
Refactor the connection timers added for re-connections in the SFU audio
bridge and make them valid for the first try as well.
Make 1010 errors (connection timeout) retriable when retryThroughRelay
is enabled.
1007 errors are still a large fraction of our overall audio join error
rate. This usually indicates some sort of firewall block or UDP issues
carrier networks. I can't figure out why some scenarios won't trickle
down to relay candidates though - I'm leaning to scenarios where STUN
packets with USE-CANDIDATE are being mangled/lost along the way or
something else that borks the (already fragile) conn checks for ICE-lite
implementations.
Add a new feature called retryThroughRelay which triggers a retry with
iceTransportPolicy=relay whenever audio fails to join with a 1007 error.
The goal is to force relay usage to try and bypass 1007s scenarios that
still happen.
Disabled by default.
Changes enableWakeLock => wakeLock.enabled to follow the pattern used by
other features and wakeLockEnabled => wakeLock. Also make the necessary
code changes to reference this new settings flags correctly.
Adds wake lock feature, which is available only for mobile users using
browser with support to the given API.
When an user using a supported device joins the meeting, a toast is
displayed offering to activate the feature.
Adds a toggle under settings menu to activate/deactivate it.
Adds a music player for ambient sound which can be turned on and off using a
toggle located inside timer panel. When stopwatch is selected, this toggle is
automattically turned off.
The initial goal is for this to be default in 2.7.
Set it as default early in the cycle so folks can test it for longer.
If there's any deal-breaking issue with it nearing release we can just flip back to the old (2.6, FS/SIP.js) default.
Enables the presenter to share a camera in the presentation area.
The shared camera automatically uses a pre-defined, fixed and hidden camera.
Profile defined in the settings.yml file.
It is currently using the screenshare's backend.
Interactions button is a button that stays in action bar.
Integrates several features in just one place: user-reaction, raise hand,
user-status (away/not away), toggle question panel.
add user-reaction collection
add emoji picker for user reaction in the user list
add options to enable/disable user-reaction
add a way to pass style to emoji-picker component
There are still a bunch of edge cases and issues with reconnection
scenarios for video:
- Signaling socket refuses to reconnect once maxRetries expire
- Race conditions on local stream attachment: local camera wouldn't be
correctly rendered _if_ the attached stream existed _without_ video
tracks yet
- Video tracks leak on local streams when replacing them (virtual bgs)
- Completely ignoring Meteor state when trying to reconnect cameras
- Streams aren't proactively stopped when the signaling socket dies
- Outbound request queues aren't isolated by stream nor are they
flushed when a newer peer with the same ID is created
- Server originated negotiation errors won't trigger a local peer
cleanup - thus leaving dangling peers that take way too long to
reconnect
This commit fixes or improves all of the aforementioned issues, +:
- Remove unused arguments in the peer (client->SFU) 'start' request
- Prevent crashes when trying to render video-list-items without user
data (which might happen on re-connections)
Reconnection timers are far too long for abrupt failures because we
are waiting the original timeouts to elapse (30-60s) before trying it
again - even if a connection worked N-sessions back in that session's
history. The ideal thing to have is another intermediate, smaller and
fixed reconnection timer for sessions that had a working screen share
at least once.
The UI is also not being updated to the reconnecting state on negotiation
failures.
* Add an intermediate reconnection timer for abrupt failures set to 8s.
This should improve reconnection times.
* Lower default connection timers values (base 20s down from 30s, max
25s down from 60s)
* Set screen share UI to reconnecting on abrupt failures as well - we
were only tracking ICE states prior to this, not negotiation errors
video-provider's current ping-pong is as good as nothing in 2.5+. We
were counting on Meteor's (and consequently the component's mount state)
before 2.5 to act as a "heartbeat" as far as the socket is concerned.
The ping-pong served only to sustain traffic for finnicky,
traffic-dependant firewall.
Since 2.5, the component's state is _kind of_ detached from Meteor's -
which means it won't unmount when Meteor disconnects. That causes the
video-provider websocket to lose its borrowed heartbeat and leads to a
bunch of reconnectiong inconsistencies, the worst of them being a stuck,
useless signaling socket that will cause cameras not to work until a
client refresh.
This commit does the following:
- Implements actual heartbeat checks to trigger signaling socket
reconnects when necessary, all within the scope of video-provider
- Remove borked, eons old 'offline'/'online' event handlers: they were
causing unnecessary camera drops AND causing video-provider to
generate a stuck signaling socket
- Properly catch WebSockets.send errors
