1874041 - Implement "togglemicrophone" and "togglecamera" MediaSession actions (e.g. from PiP window buttons)

Status: NEW

(Core :: WebRTC: Audio/Video, enhancement)

Description

[Jan-Ivar Bruaroey [:jib] (needinfo? me)]

Firefox's Picture-in-picture feature can be useful in video conferencing.

It would be even nicer if end-users had toggles for camera and microphone in the PiP window like they do in Chrome.

STRs:

1. Open https://jsfiddle.net/jib1/q0uvnm6x/
2. Click Firefox's PiP icon in the video (or the button labeled "PiP!" if in Chrome)

Expected result (works in Chrome):

• The PiP window has working toggles for camera and microphone

Actual result:

• The PiP window has no toggles for camera and microphone

Privacy:

• Implementing this securely may require Firefox to mute and unmute tracks. This is still being worked out in the spec:
