Steps to reproduce the problem:
1. Visit website
2. Press the "play" button for the video
3. Get the error message:
hlsjs: Video file not found

What is the expected behavior?
Video playback of the camera in Chesterton, IN

Works in 68.0.3340.106

What went wrong?
Instead of the video, we get the following error:

hlsjs: Video file not found

Did this work before? N/A 

Is it a problem with Flash or HTML5? HTML5
