Vimeo autoplay fails with new policy

[pikilon]

The iframe generated by Vimeo player doesn't have allow="autoplay" so or you mute it or autoplay will fail.
In the other hand youtube's one works with this attribute.
I've been diggin a little bit in the code and Vimeo Player allows to ref an Iframe itlself so it could be a good way of control this attribute before put it into the DOM (if you do it later it will fail to autoplay too)

The problem with using a rendered iframe is that Vimeo shared URLs do not work (ie https://vimeo.com/yannickcerrutti/annecydroneinmotion) whereas generating a fresh embed lets you use any Vimeo URL. The "proper" solution is to fix the Vimeo API, which I see you've created an issue for already. I think we just need to wait for Vimeo to fix it.

Also, it's worth noting that recent versions of Chrome will not autoplay Vimeo videos anyway.
