Fire event when vimeo video stops playing?

Previous answer is now obsolete since Vimeo launching the new Video Player API.

Important: Be sure to remove the ?api=1 from the URL in your iframe. This was previously required when using the Froogaloop library and is no longer needed. If you leave it in, the ‘ended’, ‘seeked’ and other events will never fire.

Include the new script:

<script src="https://player.vimeo.com/api/player.js"></script>

And then use the following example:

$(document).ready(function(){

    var iframe = $('#container iframe');
    var player = new Vimeo.Player(iframe);

    player.on('ended', function() {
        console.log('Finished.');
    });

});
