Sorry about the test flakiness. Let me go ahead and disable the test on Android until I can figure out what is causing this. It should be okay to disable, because the tested code path is currently not active in production on Android.

This test case appears to fail intermittently on Android. This CL disables the test case for Android in order to mitigate the test flakiness it causes.

The following revision refers to this bug: https://chromium.googlesource.com/chromium/src.git/+/fecb029e6187fbceb05679b0489968532de9ee28 commit fecb029e6187fbceb05679b0489968532de9ee28 Author: Christian Fremerey <chfremer@chromium.org> Date: Thu Jan 24 01:11:08 2019 [Video Capture, Android] Re-enable tests involving accelerated jpeg decoding Re-enable video capture tests involving accelerated jpeg decoding on Android that used to be flaky. There have been a lot of fixes in the video capture pipeline since these test cases were disabled. The tests pass when running locally. It is worth re-enabling. If they turn out to still produce flakiness, we can disable again and use the produced logs to investigate.
