Project Member Reported by ilnik@chromium.org, Apr 7 2017 
Enabled VP9 2SL test has some regressions comparing to what it has before regression.
Enabling commit: https://chromium.googlesource.com/external/webrtc/+/5f4aaeb0a431d4e465f7d68b574b88147f7d101f

Changes probably caused by VP9 multithreding:

Status: WontFix (was: Assigned)
Marking as won't fix.
We made a fix in libvpx for the encoding mode in this test (screen-content with spatial layers) and re-enabled the test. The fix causes some regression in frame drops (and hence psnr/sssim), but also has some positive gains in encode_time.
Another improvement may come at a later date for the current regression.
