Chrome Vimeo Iframe autoplay not working anymore

google-chrome iframe vimeo autoplay

since some days my vimeo iframe will not autoplay anymore. I know the chrome update, which will block autoplay videos with sound. Is the block already active?

The Vimeo Example code doesn't work: 

<iframe src="https://player.vimeo.com/video/12345?autoplay=1&loop=1&autopause=0" width="500" height="281" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>

But netflix.com and vimeo itself has an autoplay video on the homepage, which works.

EDIT: Chrome version 66.0.3359.139 macOS High Sierra 10.13.4

Does anyone have an idea or answer?

Thanks!

Annotating the <iframe> with an allow attribute worked for me:

<iframe ... allow="autoplay; fullscreen"></iframe>

It's called "Iframe delegation" and is described here: https://developers.google.com/web/updates/2017/09/autoplay-policy-changes.
