• bug 932562 - Allow running gtests with a b2g build / JW
  • add manual steps about building/deploying/running gtest files onto a b2g device
  • will update python scripts to automate the steps later

  • Playback may reach the end before pref change is completed for the duration is short. set 'loop' to true to keep playing so that we won't miss 'timeupdate' events.
  • patch landed, leave the bug open to watch for if there are still timeouts caused by other bugs

  • Add debugging log for DrawTargetCairo::CreateSourceSurfaceFromNativeSurface() in local patch
  • Use vendor's monkey test script to reproduce this issue. This issue didn't appear in the first round of test. And due to the reported call stack is difficult to further analyse, so we ask vendor to use non-optimized ROM to preform the test again.
