* Splitting out rtp stats stuff into its own package.
Going to be making some lighter versions of these.
Will be cleaner to have all of these grouped together.
So, as a first step, just making a package for it.
* tests
* Initial plumbing for metrics.
This implements
- metrics received from participant.
- callback to room.
- room distributes it to all other participants (excluding the sending
participant).
- other participants forward to client.
- counting metrics bytes in data channel stats
TODO:
- recording/processing/batching
- should recording/processing/batching happen on publisher side or
subscriber side?
- should metrics be echoed back to publisher?
- grants to publish/subscribe metrics.
* mage generate
* clear OnMetrics on close
* - CanSubscribeMetrics permission.
- Echo back to sender.
* update deps
* No destination identities for metrics
* WIP
* use normalized timestamp for server injected timestamps
* compile
* debug log metrics batch
* correct comment
* add baseTime to wire
* protocol dep
* Scope metrics forwarding to only participants that a participant is
subscribed to.
Also remove the participant_metrics.go file as it was not doing anything
useful.
* update comment
* utils.ErrorIsOneOf
* couple of more utils.CloneProto
* Use new track id for republishing
Always generates new track id for track publishing
to make the behavior more consistent. A republishing of
clien track will be considered as a new track publication
and always trigger trackUnpublished & trackPublished event
on subscriber side.
* remove test
* Log only when not nil.
Default logging confuses debugging as we call using nil as well to make
the call site simpler. And logging a nil makes it look like it is
incorrect seeding. `nil` fields do not seed. So, don't log when `nil`.
* log SDP
* Do not remove from subscription map on unsubscribe.
Notes in line as to why.
* Avoiding the extra check. It is fine to check under lock for clean up.
It is done in other places.
* comments
To increase visibility of ICE reconnect, logging reconnected at Infow
level. Otherwise, it is hard to see if an ICE restart finished
successfully.
Also, cleaning up ICEConnectionDetails a bit. Just separate out
read-only fields into its own struct and use it for read-only export.
* Negotiate downttrack for subscriber before receiver is ready
This change will save 1 round sdp negotiation time for
subscribing to simulcast-codec or remote node track
* solve comment
* Fix simulcast-codec case
* Do not ICE restart on an idle/not yet started peer connection.
* Skip ICE restart on unestablished peer connection.
For publish only participants, the subscriber peer connection is not
negotiated. So, ICE restart was hitting an error while trying to restart
the SUBSCRIBER peer connection.
* use ICE gathering state as peer connection state may not have changed if first offer/answer was missed
* speed up track publication
Add metrics for track publication and subscription
Return EnabledCodecs in JoinResponse so client can
choose codec without server side codec fallback
Cache remote webrtc track without AddTrackRequest to
let client send publisher offer before AddTrackRequest response
* go mod
* clean code
This allows listing, adding and deleting agent dispatches on an existing room. Requests go to a new AgentDispatchService, which sends them over RPC to the rtc.Room via the RoomManager. The rtc.Room then does agent job management using RPCs to the agent service.
