From stack frame 11 it seems we're here, but some assert is triggered, causing a "FatalLogCall" with some error message.
Two problems:
- the logging of the error probably shouldn't crash (or is it output somewhere?)
- what caused the assert here?
Any chance either of these have been fixed upstream?

This is not the logging asserting, this is libwebrtc's debug assert (RTC_DCHECK_GE
) firing (and logging) from here. That would appear to mean we're getting a negative value somewhere around here:

Maybe related to bug 1774429? Not seeing this crash on crash-stats, although there are a handful of other (rare) crashes in rtc_units_impl.

We now have 2 other intermittents that are likely duplicates of this bug. It appears something weird is happening with a timestamp in VCMTiming::RenderTimeInternal. Andreas, is this something you'd have time to look into?

This particular bug has frame_buffer2.cc on the stack, and we now use FrameBuffer3 (aka VideoStreamBufferController).
That said, the root cause seems orthogonal to which jitter buffer is being used. Also, related: https://bugs.webrtc.org/14387.
Some notes:
- In bug 1809085 we give the Timestamp a value of
-4283370913
.
From the log we know that this is not the timestamp of the first frame, because the dimensions of the sink are known:[task 2023-01-08T19:25:06.249Z] 19:25:06 INFO - testing max-fs withVP8 [task 2023-01-08T19:25:06.250Z] 19:25:06 INFO - TEST-PASS | dom/media/webrtc/tests/mochitests/test_peerConnection_maxFsConstraint.html | v2.currentTime is zero at outset [task 2023-01-08T19:25:06.251Z] 19:25:06 INFO - TEST-FAIL | dom/media/webrtc/tests/mochitests/test_peerConnection_maxFsConstraint.html | The author of the test has indicated that flaky timeouts are expected.

- In bug 1809414 we give the Timestamp a value of
-4234360650
. This is close to what we saw in bug 1809085. - Both known timestamps are reasonably close to
-0xFFFFFFFF
in int64. This is interesting given that uint32 is an input toExtrapolateLocalTime
. - In both cases we know that the inputs to the extrapolator can not originate from timestamps close to 0 on the send side's clock.
- In bug 1809414 we know that the inputs to the extrapolator can not originate from the first received frame for the stream, since we had already rendered a frame.
I did some auditing and the only possible path I see is that the current time when the extrapolator was created is smaller than the absolute value of a negative diff_ms
here. On the other hand, diff_ms
being close to -std::numeric_limits<uint32_t>::max
seems weird too.
In either case, we should verify what's happening with some new DCHECK
s.

Bug 1809414 has hit one of the new asserts:

The last patch wasn't effective because the test runner only processes stdout, not stderr.

Also log this
to distinguish between potentially more than one extrapolator.

It seems that last logging patch made the crash go away. Or did we fix it elsewhere?
