I'm getting the error message..
Uncaught (in promise) DOMException: play() failed because the user didn't interact with the document first.
..when trying to play video on desktop using Chrome version 66.
I did find an ad that began playback automatically on a website however using the following HTML:
<video
title="Advertisement"
webkit-playsinline="true"
playsinline="true"
style="background-color: rgb(0, 0, 0); position: absolute; width: 640px; height: 360px;"
src="http://ds.serving-sys.com/BurstingRes/Site-2500/Type-16/1ff26f6a-aa27-4b30-a264-df2173c79623.mp4"
autoplay=""></video>
So is by-passing Chrome v66's autoplay blocker really as easy as just adding the webkit-playsinline="true", playsinline="true", and autoplay="" attributes to the <video> element? Are there any negative consequences to this?

To make the autoplay on html 5 elements work after the chrome 66 update you just need to add the muted property to the video element.
So your current video HTML
<video
title="Advertisement"
webkit-playsinline="true"
playsinline="true"
style="background-color: rgb(0, 0, 0); position: absolute; width: 640px; height: 360px;"
src="http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4"
autoplay=""></video>Just needs muted="muted"
<video
title="Advertisement"
style="background-color: rgb(0, 0, 0); position: absolute; width: 640px; height: 360px;"
src="http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4"
autoplay="true"
muted="muted"></video>Chrome 66 のアップデートは、タブがユーザーのタブにランダムなノイズを発生させないようにしようとしていると思います。そのため、ミュート プロパティによって自動再生が再び機能します。
