The OS should not pause camera and microphone recording simply because the laptop lid is closed. If camera and mic resumes before audible playback resumes.ĭo we want to try to say anything around that?.If camera and mic don't shut off when audible playback shuts off.If camera and mic (and screen-sharing?) resume during laptop lock screen on reopen.

USB camera keeps recording when they close the laptop lid.

if laptop microphone keeps recording when they close the laptop lid.

if microphone keeps recording when they switch display off phone/tablet to put in pocket.

Thirdly, there may be common privacy issues around this behavior. Do we need to say anything more, or simply file bugs on implementations? But from my observations, browsers aren't firing them when I close and reopen the laptop lid, even though capture is interrupted. Secondly, we already have the mute and unmute user agent events for notifying JS. Should we piggyback media capture on that?

Some phone apps (like YouTube now) still play audio while screen is off (with or wo/headset)īut one commonality seems to be that most devices have some way to shut media playback up temporarily, and resume later.

A flip phone with back-display may have its back camera work as front camera when closed.

A laptop with external monitor attached may not seize media i/o.

To complicate matters, there appear to be several device exceptions: This physical act seems similar (but not identical) to pressing the physical 'display off' button on most smartphones and tablets, or closing a flip phone. It's a physical act that (sans external display) seizes display, audio output, mic & cam capture.It may trigger it, but was observed not to. Closing a laptop lid is not the same as freezing.Seperate from #668 because, as mentioned in w3c/webrtc-pc#2489 (comment):

Use laptop with lid closed
