Nope. 1743341 7 calvaris 2021-03-24 09:22:23 -0700 I don't see a crash, just a failure. 1743351 8 pnormand 2021-03-24 09:36:16 -0700 Yeah well this specific trace is 3 years old, we did several Mesa and GStreamer updates since :) Maybe update the TestExpectations then? 1743717 9 calvaris 2021-03-25 03:26:02 -0700 (In reply to Philippe Normand from comment #8) > Yeah well this specific trace is 3 years old, we did several Mesa and > GStreamer updates since :) > > Maybe update the TestExpectations then? It does not appear as crash, just as failure, so I'll update the bug summary 1753555 10 pnormand 2021-04-23 06:10:39 -0700 Test is already marked as failing in the generic TestExpectations so no need to have another one in our ports. Also since we don't support video.captureStream() anyway, I don't see how this test could pass, hence duplicate of bug 224972. *** This bug has been marked as a duplicate of bug 224972 ***
