navigator.mediaDevices.enumerateDevices() is undefined on Linux

[loloof64]

Is your feature request related to a problem? Please describe.
As I plan to develop an application based on WebRTC, I've been checking the function navigator.mediaDevices.enumerateDevices(), but when testing it on Linux (Ubuntu in my case), I got an error Unhandled Promise Rejection: TypeError: undefined is not an object (evaluating 'navigator.mediaDevices.enumerateDevices')

Describe the solution you'd like
When calling navigator.mediaDevices.enumerateDevices(), I should get the list of media devices available on the guest OS, like in a standard Web navigator.

For example

await navigator.mediaDevices.getUserMedia({audio: true, video: true});

Describe alternatives you've considered
I don't have any alternative.

Additional context
I don't have any additional context.

I think it is plateform related.

Check here the interesting compatibility review https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices
For instance your ubuntu webview might be old dated and can be accessed using a different prefix (directly from navigator, or using webkit/moz prefix)

navigator.mediaDevices. works with a recent webkit2gtk (I have 2.40.5), but the webview project needs to respond to the permission requests to allow access.
