* Add counter for pub&sub time metrics
The pub&sub shows large value in migration related case like
muted/disabled migration, the subscription time depends on
the time when publisher unmute the track(sending rtp packet
after migration), add a counter to distinguish since we
can't control the time in such cases and the first subscription
attemps also is more meaningful than those cases.
* Add info log for high publish delay
Seeing instances of both lower case and upper case mime in dynacast
manager which created duplicate entries.
Also, move the dyncast files a package.
TODO: Need to do audit and come up with a consistent way to always use
lower case for mime type.
Transport will send offer immediately if last
negotiation is before debounce interval in #1929,
it will cost two negotiation for a/v tracks if a
pubisher publishes two tracks at same time like
screenshare or enable mic/camera. This change use
a small debounce interval in this case to avoid this issue.
* Make lite version of RTPStatsReceiver called RTPStatsReceiverLite.
Refactor around that.
Will probably make some more flavors to have lighter versions still.
* update deps
* use MarshalLogArray
* use util
* 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
