* 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 delta stats throughout and avoid calculating deltas in telemetry
* Fix a few things after testing
* Remove debug
* Fix tests
* delete instead of setting to nil
* Point to the latest protocol
* Add sort by option to node selector
Allow the final decision of a selected node to be based on different
sorting options rather than just random.
Add a `sysload`, `cpuload`, `rooms`, `clients`, `tracks`, and
`bytespersec` sorting options to select the appropriate room when
multiple are suitable for the chosen selector.
Add tests for sysload sort_by option
Closes: #598
* NodeSelector: rename "random" selector to "any"
Since the selector introduces limits but the final selection is now
based on the sort by value, the random selector name does not make
sense. Rename this selector to "any" to accurately reflect that it will
select any available no with no additional selection limits.
Allow the old setting "random" to point to the new selector name, but
print a deprecation warning message.
Sometimes peerconnection jumps to disconnected periodically even
when the underlying connection is ok. In these cases we are
triggering unnecessary connection restarts.
Given this, we'll leave the responsibility of early-detecting
disconnections to clients, where they have more control/knowledge
of networking conditions.
* use negotiated data channel in migration case
* create subscriber data track after migration
* fix participant state update
* add participant leave log
* update protocol
Found another reason for potential stalling on layer switch up.
When switching up, it is possible that the key frame of the packet
at higher layer arrives very close to a packet in the currently
forwarded layer.
An inversion happens when higher layer packet arrives earlier
(as timestamped at receicver), but gets scheduled for forwarding
later (as seen by forwarder).
Because of the order of processing goroutines,
it is possible to have negative diff when trying to adjust
RTP timestamps for layer switch. A negative diff results in
large jump in RTP timestamp. Client stalls, sends PLI three seconds
later (3 seconds is a Chrome thing, not sure about others), waits
for another key frame and starts again. In the mean time, the
video is frozen.
