Bug 197707 – getUserMedia capture changes on iOS after homing out

• Status: RESOLVED
• Resolution: FIXED
• Component: WebRTC

[youenn fablet]

As per daginge in https://bugs.webkit.org/show_bug.cgi?id=196214
1. Go to https://webrtc.github.io/samples/src/content/getusermedia/gum/
2. Click "open camera"
3. Observe that frame rate is slow
4. Go to the home screen by swiping up
5.Wait at least 2 seconds
6. Open Safari again
7. Observe that the resolution has changed (black borders around the video frame), and the video is now fast again (as fast as native camera app)

[youenn fablet]

Captured frame resolution changes from 640/480 to 1280/720.
The black frames are probably due to our letter box resizing.
Moving to trim would probably get us closer to the initial captured data.

Change of camera configuration is not expected though.
