Issue descriptionUserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.90 Safari/537.36 Example URL: http://qa.unified-streaming.com/freecaster/ticket_2287/frames_13-24_skipped.mp4 Steps to reproduce the problem: 1. Play video at URL above What is the expected behavior? Video should play completely, without freezes or decoder crashes. What went wrong? Video playback stops after 12 frames. Checking chrome://media-internals shows a video decode error, the log is attached. With hardware acceleration disabled in chrome://flags the video does play without the decoder crashing, but instead freezes for 12 frames. Did this work before? N/A Is it a problem with Flash or HTML5? N/A Does this work in other browsers?

Able to reproduce this issue on Mac 10.12.6 using chrome reported version #60.0.3112.90 and latest canary #62.0.3187.0. This is a non-regression issue as it is observed from M45 old builds. Note: The video doesn't play on mac 10.12.6 even for the first frame and issue is not seen on OS-Mac and OS-Linux. Hence, marking it as untriaged to get more inputs from dev team. Thanks...!!

I can repro this bug. It is because of H/W decoder error.
