How can I autoplay a video using the new embed code style for Youtube?

Question

Just put "?autoplay=1" in the url the video will autoload.

So your url would be: http://www.youtube.com/embed/JW5meKfy3fY?autoplay=1

In case you wanna disable autoplay, just make 1 to 0 as ?autoplay=0

Actually, you will have to use the "?" instead of "&" for your first parameter only. If you use more than one parameter, you will then have to add "&" to the chain.

For instance, if you want to add autoplay and closed captioning, you will have to add this portion to your embedded video URL: ?autoplay=1&cc_load_policy=1.

It would look like this:

<iframe width="420" height="315" src="http://www.youtube.com/embed/
oHg5SJYRHA0?autoplay=1&cc_load_policy=1" frameborder="0"
allowfullscreen></iframe>

You need to add an extra parameter, alongside the autoplay=1

allow="autoplay"

making it:

<iframe src="your-video-url?rel=0&amp;controls=0&amp;showinfo=0&amp;autoplay=1" frameborder="0" allow="autoplay; encrypted-media"></iframe>

The only way I was able to get autoplay to work was to use the iframe player api.

<div id="ytplayer"></div>
<script>
// Load the IFrame Player API code asynchronously.
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/player_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
// Replace the 'ytplayer' element with an <iframe> and
// YouTube player after the API code downloads.
var player;
function onYouTubePlayerAPIReady() {
    player = new YT.Player('ytplayer', {
        height: '480',
        width: '853',
        videoId: 'JW5meKfy3fY',
        playerVars: {
            'autoplay': 1,
            'showinfo': 0,
            'controls': 0
        }
    });
}
</script>

Okay this is an example for the new embed code for youtube videos.

<iframe title="YouTube video player" class="youtube-player" type="text/html" width="560" height="345" src="http://www.youtube.com/embed/8v_4O44sfjM" frameborder="0" allowFullScreen></iframe>

if you want to autoplay it, at the src="http://www.youtube.com/embed/8v_4O44sfjM" add the ?autoplay=1 parameter

So the code will look like this:

<iframe title="YouTube video player" class="youtube-player" type="text/html" width="560" height="345" src="http://www.youtube.com/embed/8v_4O44sfjM?autoplay=1" frameborder="0" allowFullScreen></iframe>

i tried this on my blog and it works ! Hope this help (:

None of the above worked for me in the current youtube embed. Try this, it actually worked for me :)

Hope it helps!

<iframe width="925" height="315" src="https://www.youtube.com/embed/iD5zxjySOzw?rel=0&amp;autoplay=1&amp;controls=0&amp;showinfo=0" frameborder="0" allowfullscreen></iframe>

Chrome blocks audio content being played without any user interaction.

So, a work-around is to start the video muted by adding

&mute=1

This will work 100% of the time.
