Attached patch undo_d26db5427e8a.patch (obsolete) — Splinter Review
STR:
1. On a Windows box with an HD webcam (like Logitech C910 or higher)
2. Open URL
3. Hit [Start!] button and share the camera.

Expected result:
- Success: 1280x720

Actual result:
- Success: 640x480

Tests performed:

Windows 7 FF 32.0:  Success: 1280x720 (good)
Windows 7 FF 34.05: Success: 640x480  (bad)

mozregression only got me so far on my Windows setup:
Last good revision: 0aaa2d3d15cc
First bad revision: 111a1da2a95d

The culprit is https://hg.mozilla.org/integration/mozilla-inbound/rev/d26db5427e8a

I've attached a reverse patch of that commit and verified that it fixes this bug on my Windows 7 machine.

Thanks Florin for catching this in Bug 1094539 comment 17! I'll try to work on some automated tests so this doesn't keep breaking every few months. :-/
Ugh, let's see if we can fix the bug in that patch because regressing 929431 renders WebRTC (and by extension Loop) unusable for a lot of people.
