With the patch I just submitted, the behaviour would be as the following: - No permission - Enumerate devices returns only two devices just like before - Stream Track is not applicable since there's no active video/audio steam - With permission - Enumerate devices returns ***all*** the available devices with fake ids, fake group ids, and fake names. - Stream Track returns the fake ids and names `MediaManager::AnonymizeDevices` seems more integrated. So I think modifying it instead of `MediaEngineFake` makes more sense. Unfortunately, the patch won't fix https://webcamtests.com/check's issue. Firefox returns the full list after permission grant, but the website doen't refresh the media device list after permission grant. This is something they would have to do.
