HTML 5 Video “autoplay” not automatically starting in CHROME

问题

I have the following code:

<video controls autoplay>
  <source src="video/myVideo.mp4" type="video/mp4"> 
  <source src="video/myVideo.webm" type="video/webm">
  <source src="video/myVideo.ogv" type="video/ogg">   </video>

The video:

displays well in both Chrome and Firefox
In Firefox it plays as expected
In Chrome it displays but not "autostarts". This is the problem.
If I click on it (in Chrome) it plays ok

Tried

<video controls autoplay>...</video>
<video controls autoplay="1">...</video>
<video controls autoplay="autoplay">...</video>

Nothing worked in Chrome

Then I also tried changing the codec, as recommended in https://en.wikipedia.org/wiki/HTML5_video, but it also did not work:

<source src="movie.webm" type='video/webm; codecs="vp8.0, vorbis"'>
    <source src="movie.ogv" type='video/ogg; codecs="theora, vorbis"'>
    <source src="movie.mp4" type='video/mp4; codecs="avc1.4D401E, mp4a.40.2"'>

So now I am at a dead end. Thanks for any pointers! Much appreciated.

You need to add playsinline autoplay muted loop, chrome do not allow a video to autostart if it is not muted, also right now I dont know why it is not working in all android devices, im trying to look if it's a version specific, If I found something I'll let you know

Chrome issue: After some research i have found that it doesnt work on chrome sometimes because in responsive you can activate the data saver, and it blocks any video to autostart

I was just reading this article, and it says:

Important: the order of the video files is vital; Chrome currently has a bug in which it will not autoplay a .webm video if it comes after anything else.

So it looks like your problem would be solved if you put the .webm first in your list of sources. Hope that helps.

This may not have been the case at the time the question was asked, but as of Chrome 66, autoplay is blocked.

Try this when i tried giving muted , check this demo in codpen

    <video width="320" height="240" controls autoplay muted id="videoId">
  <source src="http://techslides.com/demos/sample-videos/small.mp4" type="video/mp4">
  Your browser does not support the video tag.
</video>

script

function toggleMute() {

  var video=document.getElementById("videoId");

  if(video.muted){
    video.muted = false;
  } else {
    debugger;
    video.muted = true;
    video.play()
  }

}

$(document).ready(function(){
  setTimeout(toggleMute,3000);
})

This question are greatly described here
https://developers.google.com/web/updates/2017/09/autoplay-policy-changes

TL;DR You are still always able to autoplay muted videos

Also, if you're want to autoplay videos on iOS add playsInline attribute, because by default iOS tries to fullscreen videos

Try this:

<video src="{{ asset('path/to/your_video.mp4' )}}" muted autoplay loop playsinline></video>

And put this js after that:

window.addEventListener('load', async () => {
  let video = document.querySelector('video[muted][autoplay]');
  try {
    await video.play();
  } catch (err) {
    video.controls = true;
  }
});

回答7:

Extremeandy has mentioned as of Chrome 66 autoplay video has been disabled.

After looking into this I found that muted videos are still able to be autoplayed. In my case the video didn't have any audio, but adding muted to the video tag has fixed it:

Hopefully this will help others also.

回答8:

These are the attributes I used to get video to autoplay on Chrome - onloadedmetadata="this.muted = true", playsinline, autoplay, muted, loop

Example:

<video src="path/to/video.mp4" onloadedmetadata="this.muted = true" playsinline autoplay muted loop></video>

Here is it: http://www.htmlcssvqs.com/8ed/examples/chapter-17/webm-video-with-autoplay-loop.html You have to add the tags: autoplay="autoplay" loop="loop" or just "autoplay" and "loop".
