Detect HTML video autoplay prevention

Mobile browsers prevent video autoplay for understandable reasons. I have a video background on a site, so control buttons are out of question, but I thought that I could pop up window with some info and a button, where the user can accept the background video (triggering manual play) or not, and change it to some static pic.

So the question is: is there a way to tell if the autoplay was interrupted by the browser?

I tried onerror but it doesn't fire so I tried to onsuspend as well:

HTML:

<video id='bgvid' src='bgvid.mp4' type='video/mp4' autoplay loop onsuspend='video_suspended()'>

Javascript:

function video_suspended() {
    $bgvideoElement=$("#bgvid").get(0);
        //Check if reason for suspend was completion or browser interruption
        if($bgvideoElement.readyState<1) {
            //Here comes some pop-up window and a button to
            $bgvideoElement.play();
    } 
}

It works pretty well on tablet (Chrome), but on desktop (Chrome) onsuspendkeeps triggering infinitely (Firefox is alright though).

Any ideas on Chrome problem or any alternatives?

You can always test if current browser will run video.play() method. This method is asynchronous and returns response or error, https://developer.mozilla.org/en-US/docs/Web/API/HTMLMediaElement/play.

The algorithm of testing consists of checking if we got the error after trying to run .play().

export const checkUserAgentVideoAutoplay = async () => {
  const video = document.querySelector('#video-bg');

  try {
    await video.play();

    video.setAttribute('autoplay', true);

    console.log('video started playing successfully');
  } catch (err) {
    console.log(err, 'video play error');
    // do stuff in case your video is unavailable to play/autoplay
    // show user that video autoplay was aborted  
  }
}

This is what says the console in Safari, which refuses playing .webm video format

AbortError: The operation was aborted.
"video play error"

There is no javascript standard function that matches your specification, since it's a security feature of mobile browsers... (It can prevent cellular data waste). But, if you have tried the code and it is working only in mobile browsers, you can write a code that detects you if you're on mobile, and if so, enable the handler:

HTML:

<video id='bgvid' src='bgvid.mp4' type='video/mp4' autoplay loop>

Javascript:

window.onload = function() {
    var isMobile = false;
