Video/Media tests consistently failing veyron machines

Project Member Reported by sbasi@chromium.org, May 3 2016

Issue description

There have been a large number of failures for the Video tests in the last 10 hours:

https://bugs.chromium.org/p/chromium/issues/list?can=2&q=histogram+bucket+found+at+%3C+100%25&colspec=ID+Pri+M+Stars+ReleaseBlock+Component+Status+Owner+Summary+OS+Modified&x=m&y=releaseblock&cells=ids

Majority of the errors are some variant of: "Media.GpuVideoDecoderInitializeStatus not loaded or histogram bucket not found or histogram bucket found at < 100%"

This is a tree closer. According to marcheu@ this requires posciak@ 's attention but he is OOO this week.

Sheriffs can you please disable the tests from the suite then reassign this bug to posciak to take a look later?

What's an eta for the revert of this CL? These are very important tests and we don't want to lose video test coverage from these tests.

Is there a better way to handle platform specific regressions so the whole tree doesn't get affected?
just in case this is not clear: these tests have been disabled only for veyron platforms. Can this wait til posciak@ is back in the office (apparently next week)?

If not - I am not sure who else is the right person to look into this, marcheu@ would know?
Yes posciak and tfiga.
and one more thing, the patch description is misleading, the only excluded tests are

video_ChromeHWDecodeUsed
video_ChromeRTCHWDecodeUsed
video_ChromeRTCHWEncodeUsed
video_ChromeVidResChangeHWDecode

Fix V4L2 device failed to create on veyron board

This was broken since CL 6e70beb8, gpu & media refactoring.

This CL modified the build rule, so dependencies of media/gpu will define USE_LIBV4L2 automatically, which is needed by
content/common/sandbox_linux/bpf_gpu_policy_linux.cc.

TEST=play video on veyron and VDA works

Can the auto test be re enabled?
This was fixed in 8289.0.0 / 52.0.2726.0. Kuang-che. Please re-enable the test.
Labels: VideoShortList
https://chromium-review.googlesource.com/#/c/342080/ needs to be reverted to re-enable the test.
