Browsers

What is tested, not what should work.

Tested

Chromium (Chrome)Recording, processing and the live call; the sync and reliability tests, including an hour with nothing lost
FirefoxRecording (WebM VP8 + Opus), processing and the live call
WebKit (Safari’s engine)Recording as WebM, and as MP4 the way older Safari does; the live call
Safari (real, macOS)As the guest in the sync test, with Safari’s test microphone: over an hour every second of its sound is in its file, evenly spaced. The gap between a Safari guest and the host isn’t measured, and the hour’s run hasn’t been repeated since its host-side check was corrected

Not tested yet

Edge (Chromium-based), Android Chrome, Safari on iPhone and iPad, the live call in real Safari, and real cameras and microphones. On phones, recording stops when the tab goes to the background; the green room warns about it. The full matrix is in docs/browser-support.md.
