1.2%-200% regression in media.tough_video_cases_tbmv2 at 482230:482372

Project Member Reported by wolenetz@chromium.org, Jun 28 2017 
These 106 alerts look valid. There are 372 other alerts in two groups (96+276) which have regression ranges that intersect these 106's range, so I expect likely duplication upon successful bisection of these ~478 alerts.
