To get an alternative video input from MediaDevices.getUserMedia, my understanding is that you need to pass in the deviceID as a constraint. But, in Safari, to get access to deviceIDs via enumerateDevices, I need to call getUserMedia and get permission from the browser first (maybe there's another way?). The problem is that this initial getUserMedia call only returns device info for devices I've given permission for, so I still don't have the deviceID of the alternative video input.

How can I get the deviceID for this video input?

In my case, I'm trying to find the deviceID for Snapchat's "Snap Camera". In Chrome, I'm able to find and stream this video input.

    Desktop Safari? Mobile Safari? They're not quite the same. At any rate, once your user has granted permission for any video device, you can enumerate all video devices available to the browser. It's possible Safari can't use this Snap Camera. Apple's Safari team are playing catch-up on all this media stuff. – O. Jones Oct 22 '20 at 12:40
  • I've only tested on desktop. And thanks, that'd makes sense. – Thomas O'Brien Oct 23 '20 at 00:10
  • I see Snap Camera isn't available on Whereby calls in Safari either. – Thomas O'Brien Oct 23 '20 at 00:13
