How do I detect if the HTML5 autoplay attribute is supported?

Question

How do I best detect whether a browser\'s HTML5 video element supports autoplay?

On current iOS Safari, for example, autoplay is disabled.

Answer 1

Maybe I respond a little bit late but I just test a solution which work fine for me :

var loadStarted = false;

video.onloadstart = function(){
    loadStarted = true;
};

function checkRunning(){
    if(!loadStarted) removeVideo();
}

setTimeout(checkRunning, 1000);

The setTimeout is not very clean, but the overall solution is super simple like that !
