* Support participant identity in permissions
It is harder for clients to update permissions by SID as remote
reconnecting means a new SID for that participant. Using participant
identity is a better option.
For now, participant SID is also supported. Internally, it will
get mapped to identity. Server code uses identity throughout after
doing any necessary conversion from SID -> Identity.
* Address comments
* Prevent stats update if the deltas are empty
* increase force interval
* static check
* Change max delay to 30 seconds
* Restart the max subscribed quality timer on ICE restart.
Force an update after a restart to let clients apply dynacast settings.
Also, set the max expected layer to HIGH on restart so that stream
tracker starts up fast on a restart.
* fix test
* use negotiated data channel in migration case
* create subscriber data track after migration
* fix participant state update
* add participant leave log
* update protocol
* feat: unpublish tracks after publish permissions are revoked.
Uses protocol 7 to indicate client support, otherwise it attempts to
mute the tracks.
Also sends back permissions objects of all participants, and cleaned up
our handling of various permissions attributes.
* fix static check
* Consolidating PLI throttle
Use the throttler in `sfu.WebRTCReceiver`.
Does change shape of config object.
* Move PLIThrottleConfig to sfu.WebRTCReceiver
* fix test compile
* Cleaning up unused stuff
* improve readability
* RTT
- Calculate down track RTT using RTCP Receiver report
- Surface it back to the participant
- Participant updates all its published trackes
(throttled to limit update to once in 5 seconds)
- That propagates to all the upstream sfu.Buffer and the nacker.
So, we will have RTT throttled NACKs.
* rtt callback
* Use ParticipantInfo version to ensure consistency
Deprecating time.Time and avoid locking unnecessarily
* properly adjust ulimit. update protocol
* Save initial version from params
* get rid of metadata field, use grants copy
* fix test
* Ensure autosubscribe is honored when subscription permissions were granted later
* negotiate even if no media has been added
* don't double-negotiate
This ensures client reconnect attempts would be successful for long running rooms. It also fixes inaccurate permissions that were set incorrectly when full reconnections take place.
* Refactor media track subscriptions
- To enable re-use of common bits
- Add max quality from other nodes
* Lock close handlers slice
* Reverting multiple on close handlers of downtrack, unclear if it is needed yet
* Make Logger a pointer
* audio level in MediaTrack like remote media track
* Cleanup
* Add a no subscribers callback
* Add method to update subscribed quality from another node
* loss proxying from remote node
* Address comments from David
* create subscriber node quality map
* WIP commit
* update protocol
* Fixing a test and catching one place where casting was missed
* Fix one more spot which need conversion from livekit.RoomName -> string
* do not covert list
* WIP commit
* Add some tests
* allowedSubscribers uses participant sid
* correct variable name
* correct another variable name
* Add ParticipantSid to SubscriptionPermissionUpdate message
* protocol v0.11.2
* WIP commit
* WIP commit
* fix tests
* Remove unused code
* Close uptrack manager
* Remove duplicate close
* move comment to the correct line where the loop could be long
* Fix disallowed list revocation, thank you Jie
* Remove unneeded interface method
* RemoveSubscriber in Participant
* Clean up disallowed subscriptions and handle permissions on new track addition
* add test for track addition after permission set
* Remove unnecessary check
