uname exists in /bin on Ubuntu. As such, the installation fails.
The script determines the OS without specifying the complete path to uname. Do
the same in order to determine ARCH.
* Seed snapshots
- For one cycle after seeding, delta snap shot can get a huge gap
because of snapshot iitializing from start if not present. Not
a huge deal sa it should not affect functionality, but saving/restoring
(at least with down track) snap shot is a big deal. So just do it.
- Have been seeing a bunch of cases of delta stats getting a lot of
packets due to out-of-order (what seems like) receiver report. So,
save the receiver report and log it when out-of-order is detected
to understand if they are closely spaced or something else could be
happening.
* Remove comment that does not apply anymore
* log current time and RR
* Notify max layer taking into account overshoot.
An attempt to handle case of FF stopping layer 0, but not layer 1.
When max subscribed layer is layer 0, server allows overshoot to layer 1
to ensure continued streaming when the channel is not congested.
But, dynacast could have reported maximum subscribed layer as layer 0.
This is a very simple attempt to address that by taking overshoot
into account. Needs testing if this works well or not.
NOTE: When subsriber/down track is unmuted, it will report
the max subscribed layer as the max required layer. In those cases,
if the client does not start layer 0, there will still be an issue.
IOW, server is not keeping track of client behaviour that the client
has stopped layer 0 and publishing only layer 1. Server is just
accommodating overshoot with this change.
* Fix a couple of tests and change reflect.DeepEqual -> require.Equal as
much as possible
- ticker.Stop always
- clean up timer func (if they are added) on participant close
- sequencer test enhancement to add a real packet after a pdding packet
Have been seeing a few instances of "too many packets expected in delta"
when trying to generate RTCP SR on down track. Actual sequence numbers
indicate that start is after the end.
As down track RTPStats are driven by receiver report, wondering if we
are getting RTCP_RR out-of-order somehow causing this to happen.
Cannot find any other reason for this.
So, accepting RTCP_RR based update only if the sequence number is higher
than existing and also logging a warning with sequence numbers if they
look out-of-order.
Padding packets do not need the full structure. They just
need a placeholder in the sequencer array. So, use pointers
(with padding slots filled by nil) to save some memory.
Also, don't need padding for audio (yet). As padding packets
are used only for probing and we do not probe using audio tracks (yet).
Now only set mapping when user_external_ip enabled or node_ip is
explicitly set. If multiple local address resolved to same external
ip, only the first one will be mapped to external, avoid candidate
conflict between different clients.
* Cache RTPStats and seed on re-use
When a cached down track is re-used, RTPStats was not cached.
This caused sender reports getting out-of-sync with the remote side.
Cache RTPStats and seed it on re-use.
* staticcheck
