Once the second part of bug #1461600 is implemented, the user will be
able to select which camera to use from the permission prompt, instead
of having to change the default camera in the settings (which
incidentally affects all domains, not just the current one).

That, together with the fix for bug #1554202, will enable switching
cameras in the webapp container.

I think that changing the default camera in the settings doesn’t update
the camera currently being used by the current page precisely because in
the future there will be a way to select the camera to use per-domain.
Changing the default camera should affect only future decisions, not
past/current ones.

In light of that, I’m marking this bug a duplicate of bug #1461600.

Title:
  Switching cameras requires web page reload in webbrowser-app, not
  available in webapp-container

Status in webbrowser-app package in Ubuntu:
  Confirmed

Bug description:
  When a web site uses WebRTC for video conferencing the webbrowser-app
  accesses the rear camera by default. The user can switch cameras via
  Settings -> Privacy & Permissions -> Camera & Microphone.
  Unfortunately, changing this setting doesn't immediately have effect
  on the open web page. You have to reload the page first, which is not
  intuitive.

  Tested with bq Aquaris E5 Ubuntu Edition, OTA-9.1 (vegeta).

  Additional question: How can switching cameras be handled in web apps
  (driven by the webapp-container binary)? The webapp-container does
  neither provide a feature to specify a (different) default camera nor
  an interactive possibility to do so. An API call to switch cameras
  would be awesome.

  Expected Behavior
  -----------------

  - Switching cameras via the settings immediately has effect on the camera used by web sites open in the webbrowser-app.
  - Specifying a default camera (startup settings) is available with the webapp-container binary.
  - Switching cameras programmatically (via an API call) and/or interactively is possible in web apps driven by the webapp-container.

  How to Reproduce
  ----------------

  1.) Go to e.g. https://appear.in/test-drive on your Ubuntu phone (default webbrowser-app)
  2.) When prompted for "Allow this domain access the camera and microphone" choose "Yes"
  3.) Click away the chat window (touch the down-arrow at right lower corner)
  4.) Touch the screen to dismiss the "help text" (the video captured by the rear camera is shown)
  5.) In the browser address bar got to Menu -> Settings -> Privacy & Permissions -> Camera & Microphone, and switch to the front camera; go out of the menu going back the hierarchy; the rear camera video is still shown
  6.) Tap the address bar, tap on the "Reload" icon to reload the page; the front camera video is finally shown
