Description: imported/w3c/web-platform-tests/webrtc/RTCPeerConnection-videoDetectorTest.html The first failure that I saw on the dashboard was 5/6/2022 at r293885, and the dashboard shows passing on r293882. Between r293883 and r293885 probably introduced the consistent failure. REPRODUCTION STEPS I can reproduce this on r293885, but repro against all earlier commits are also failures which is different from the dashboard history.

imported/w3c/web-platform-tests/webrtc/RTCPeerConnection-videoDetectorTest.html ran on average 24 ms before r293885 and is now running on average 135 ms.
This would be seconds, not milliseconds. I see the same stderr message in passing builds, so that part is not a regression.
I have marked this test as slow while this issue is investigated.

The test history does indeed suggest that this started with r293885 / 250343@main, and that is the only WebRTC related commit in the range.
