I only tested with flatpak (successfully) I have the impression the opus encoder hasen't been built. The error is a bit strange but I think it might be some weirdness of libwebrtc caused by unbuilt opus support. 1488299 2 mcatanzaro 2018-12-15 09:57:43 -0800 Yes, WebKit's JHBuild. (I'm anxiously awaiting a resolution to bug #191196.) I guess it goes without saying that a missing encoder or decoder shouldn't cause a crash, so perhaps it's fortunate if the jhbuild is missing something that uncovered this. 1488301 3 tsaunier 2018-12-15 10:40:18 -0800 We should make opus a hard dependency fmpov 1747419 4 calvaris 2021-04-06 07:40:37 -0700 I am seeing now: ASSERTION FAILED: isInWebProcess()
