video playback issue on iphone

Video can play inline on iOS, but  the video tag needs to have the proper attributes and the video must be muted. You may be able to add the attributes with JavaScript but not sure if it will work since the video tag is more than likely already in the DOM.

The attributes are:

autoplay muted playsinline.

The JavaSscript would be:

var vid = document.getElementsByTagName("video")[0];

if(vid !==null || vid !== undefined )

{

vid.setAttribute("playsinline","");

vid.setAttribute("muted",true);

}

I am having the same issue. Is there a solution for this? It's a real problem for my client's users.
