mcasas@, do you think https://codereview.chromium.org/2286303003 might be the culprit?  It's the only change in the range that looks at all related.

I can't make a causal connection though, so I'm not going to revert it yet unless you see a reason it might cause this failure.  I'm currently trying to repro the failure locally.

Hmm I don't see exactly how my CL could break just that particular
bot, perhaps it's the v8 or the Blink rolls?  If you can't find
a culprit feel free to revert mine, I can re-land it if it's not
guilty.

Almost certainly related failure: https://uberchromegw.corp.google.com/i/chromium.android/builders/Lollipop%20Phone%20Tester/builds/6674

org.chromium.android_webview.test.MediaAccessPermissionRequestTest#testGrantAccess timing out

Regression range on that one is strictly wider though so that doesn't help narrow down.

Revert of Video capture Android: enable unittests for Camera2 API (patchset #5 id:220001 of https://codereview.chromium.org/2286303003/ )

Reason for revert:
Caused WebViewLayoutTest#testMediaStreamApi and MediaAccessPermissionRequestTest#testGrantAccess to consistently fail.

Confirmed locally by reverting patch, commenting out @DisableIf and running:

BUG= 644910 

Original issue's description:
> Video capture Android: enable unittests for Camera2 API

> This CL reenables a bunch of VideoCaptureDeviceTest
> test cases for Android and for the "new" APIs
>
> For this:
> - adds a |mTestMode| to VideoCapture.java, interface
>  of all camera java classes. VCCamera2.java tests this
>  flag and adds a capture thread if it's set.
> - the C++ correspondent classes get a method to configure
>  the java side for testing, and a method to test if the
>  underlying platform is using the new or the old APIs.
>
> Also:
> - Removes DeAllocateCameraWhileRunning because it was
>  equivalent to CaptureWithSize test case.
> - Cleans up/refactors some parts of the unit tests, adds
>  a few more comments etc
