Chrome not autoplaying video

Question

I'm using autoplay video sporadically throughout a client's site, however the below code is (for some reason), not autoplaying in Chrome(63.0.3239.132). Works fine in Safari and FF.

I am not getting any console errors either?

<video
    src="https://player.vimeo.com/external/247833422.hd.mp4?s=8d872a36d3dbe7f74e9613ab144d088b5bab6649&profile_id=174"
    poster=""
    preload
    autoplay
    loop
    muted>
</video>

Answer 1

Quick fix for Chrome:

<video
    id="video1"
    src="https://player.vimeo.com/external/247833422.hd.mp4?s=8d872a36d3dbe7f74e9613ab144d088b5bab6649&profile_id=174"
    poster=""
    preload
    autoplay
    loop
    muted>
</video>
    
<script> 
    document.getElementById('video1').play(); 
</script>
