Chrome Vimeo Iframe autoplay not working anymore

问题:

since some days my vimeo iframe will not autoplay anymore. I know the chrome update, which will block autoplay videos with sound. Is the block already active?

The Vimeo Example code doesn't work:

<iframe src="https://player.vimeo.com/video/12345?autoplay=1&loop=1&autopause=0" width="500" height="281" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>

But netflix.com and vimeo itself has an autoplay video on the homepage, which works.

EDIT: Chrome version 66.0.3359.139 macOS High Sierra 10.13.4

Does anyone have an idea or answer?

Thanks!

yes, according to their documentation it is.

EDIT:

Advance browsers like FireFox, Chrome and Safari are now blocking video autoplay by default.

CHROME Auto-Play Policy:

https://developers.google.com/web/updates/2017/09/autoplay-policy-changes

The Media Engagement Index, or MEI for short, a way of Chrome is to allow AutoPlay audio on your page to be based on your previous interactions with this webpage as a user. You can see what this looks like by going to

chrome://media-engagement/

MEI is calculated per user profile, and is persisted to incognito mode.

FIREFOX Auto-Play Improvements:

NOTE: Don’t assume a media element will play, and don’t show the pause button from the start. Look at the Promise returned by the play function on HTMLMediaElement to see if it was rejected:

var promise = document.querySelector('video').play();

if (promise !== undefined) {
    promise.catch(error => {
        // Auto-play was prevented
        // Show a UI element to let the user manually start playback
    }).then(() => {
        // Auto-play started
    });
}

Annotating the <iframe> with an allow attribute worked for me:

<iframe ... allow="autoplay; fullscreen"></iframe>

It's called "Iframe delegation" and is described here: https://developers.google.com/web/updates/2017/09/autoplay-policy-changes.

You need to add &muted=1 to the iFrame src path and you need to add the attribute allow="autoplay" to the iFrame. Now the Vimeo video starts automatically again in Chrome.

回答4:

Now the autoplay video just works if the audio is muted, you need to add the muted parameter into your api or iframe code &muted=1, you can change your browser preferences to allow autoplay unmuted videos: chrome://flags/#autoplay-policy Change the default option to "No user gesture is required"

If the user clicks the video you can unmuted it!!

回答5:

Autoplay + Mute + Start at time x sec =

<div>
    <iframe src="https://player.vimeo.com/video/342787403?&autoplay=1&loop=1&title=0&byline=0&portrait=0&muted=1&#t=235s" style="position:absolute;top:0;left:0;width:100%;height:100%;" width="1400" height="900" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen>
    </iframe>
</div>

#t parameter must be the last one.

If you are paid member and want to use video as a background, this is probably what you need:

?background=1: This parameter automatically disables all elements in the player (play bar, buttons, etc), autoplays, loops, and mutes your video on load. Please note: the background parameter is only supported for videos hosted by paid members. Learn more here.

Or, if you are not:

?muted=1 This parameter will automatically mute your video on load. Once your video plays, viewers can manually un-mute by clicking on the volume bar within the player.

BUT, I still can't make it work on the phone.
