Start Video Element on Loading page

How do you make a video element with sound to start on loading page…? If the only option is custom code…can someone dumb this down for me? THANK YOU

I think you can autoplay a youtube video by setting its online autoplay parameter to 1 like so:

&autoplay=1

you can make a video start on page load using custom code and the vimeo player API. From a UX point of view, it is generally not encouraged to have a video autoplay with sound… you can do it on desktop but mobile devices won’t allow you to autoplay video unless they have mute mode on.
