I've checked a lot of post on the same argument, but I didn't find a solution.

My html code is the following (it is an Odoo 11 web page):

<video playsinline="true" autoplay="true" muted="true" loop="true" 
    class="bckgroundMyVideo" poster="/web/image/5016" preload="auto">
    <source src="/web/image/5644" type="video/mp4"/>
    <source src="/web/image/5658" type="video/webm"/>
</video>

it is working on chrome/firefox/edge, but not on Ipad or Iphone, I've tryed a lot of combination, but as of now I'm not able to let it work on safari.

Any suggestion?

thanks
