* Optimise some bits in rtpstats_receiver
RTPStatsReceiver.Update is one of the high CPU bits. Taking some
suggestions from Cursor. Makes the `Update` function verbose though :-(
* zap.Inline logging fields
* rename
* Set up audio config in audio level module when config is updated.
It is possible to get audio config after bind (bind is where the audio
level module is created) for remote tracks. So, split out setting audio
level config in audio level module and invoke it when config is updated.
* coderabbit review
* prevent divide-by-0
* not active before config
* Do not increase max expected layer on track info update.
When max expected layer increases, the corresponding trackers are reset
so that first packets from those layers can trigger a layer detected
change enabling quick detection of layer start.
A track info update changing max to what is in track info could set the
max expected to be higher without resetting the tracker. And that would
cause dynacast induced max layer change to miss tracker reset too.
Sequence
- dynacast sets max expected to 0
- track info update sets it to 2
- dynacast sets it to 1 --> this should have reset tracker on layer 1,
but because it is less than current max (2), it is skipped.
* thank you CodeRabbit
* force update on start
To allow using "participant closing" log entry for calculating things
like session duration by paricipant kind or some other client SDK based
attribute.
* Reducing some info level logs.
Also, relaxing the check for runaway RTCP receiver report to allow for
rollover to catch up if it is not too far away.
* set logger
With audio simulcast codecs, it is possible that the clock rate of the
primary codec is different from the secondary codec. If a subscriber
binds to the secondary codec, the clock rate should be set correctly. Do
it at bind time.
* debug participant update
* more debug
* context logger
* log participant info
* more logging
* clear participant cache on disconnect
* clean up
* clean up
* Do not restart receiver on codec change mid-session.
This is not supported and was an erroneous change during the
receiver_base/buffer_base + RTP stream restart consolidation. Also make
the codec munger creation more resilient.
* fix test
In some paths, it is better to preserve pre-recorded time. So, make the
base implementations preserve the RTCP Sender Report receive time.
Also, add a method to enable forwarding packet arrival time. Could be
used across relay.
