This bug hasn't been modified for more than a year. Is this still a valid open issue?

Summary: VideoCaptureExternalTest.FrameRate flaky on Windows and Mac (was: VideoCaptureExternalTest.FrameRate flaky on Windows)
In  bug 5709 , jbauch@ reported new issues similar to this one.

I suggest we:
1) Change EXPECT_TRUE to EXPECT_GT and EXPECT_LT so we can see what the values are when it fails (at
2) Increase the tolerance to reduce flakiness (possibly after gathering more data after submitting the above).

This is still flaking on Mac, since it was not disabled on that platform. Preparing a CL to disable on Mac too.

Latest failing run:

[ RUN      ] VideoCaptureExternalTest.FrameRate
../../webrtc/modules/video_capture/test/ Failure
Value of: capture_feedback_.frame_rate() >= 25 && capture_feedback_.frame_rate() <= 33
  Actual: false
Expected: true
No of timing warnings 86
[  FAILED  ] VideoCaptureExternalTest.FrameRate (6549 ms)

If we want to keep this test I think it makes more sense to make this a perf test that reports RESULT= rather than have it flake on thresholds not being large enough.
