Bug Description

A web app that displays a website trying to access camera and microphone (for video conferencing, using WebRTC) will be refused to access the camera despite the "camera" policy_group in apparmour.

The trust-store dialog pops up in the webbrowser-app for a website such as [1], but it doesn't pop up when the website is embedded with webapp-container.

The webapp container needs to hook to the webview’s mediaAccessPermissionRequested signal, similar to what’s done for geolocationPermissionRequested.

I can confirm this has been (sort of) fixed with OTA-10. However, a confirmation to access the camera is now asked for *every single time* I open the webapp. Not sure if this is by design or a bug.

NOTE: Interestingly, access to the microphone alone (I guess that was it) is only asked the very first time you open the webapp. So, the very first time (only) you use the app you have to confirm *two* dialog.

@Peter: the fact that the permissions are not remembered is a known issue in oxide (missing functionality, really), see https://blueprints.launchpad.net/oxide/+spec/site-settings.

I can confirm that the permission and remember-permission issues are now fixed (as of OTA-12, OTA-13). Unfortunately, the Appear.in video chat application is still non-functional as it now suffers from an upside-down image of the person using Ubuntu Touch.
