I can't get Firefox to trigger download and install of OpenH264 through webrtc usage, or the install is so slow that it takes a long time. Also there is no UI as we have with the Widevine CDM. This is pretty bad experience. STR: 1) create a fresh profile through about:profiles 2) launch a browser in that profile 3) open about:addons / plugins 4) open about:profiles, and open the profile folder 5) navigate to https://jsfiddle.net/jib1/02j8q6h9/show, click gUM!, approve camera access Result: Error: Couldn't find offset 0 of codec H264 while looking for offset 0 in sdp, and there's no receiver video After two or three restarts and about five minutes, everything work.
