Question

I’m trying to put YouTube thumbnail and Vimeo thumbnail together in the same script, but its not really easy for me because I’m a new to jQuery.

I would to ask if somebody could take a look to this jQuery script that works fine in any browser: http://jquery-howto.blogspot.com/2009/02/how-to-get-youtube-video-screenshot.html

I’ve also seen the question: Get img thumbnails from Vimeo?, but there’s nothing about how to do it with jQuery.

I think it should be very easy to make for who already know the jQuery coding, and it would be the definitive solutions for who’s going to make a Tumblr theme that uses both videos.

You do this by observing that YouTube video thumbnails have a distinct URL pattern, which you can generate by parse out the video id. Vimeo thumbnails can be obtained similarly, but parsing out the video id and then using the simple API to obtain the link to the thumbnail.

I wrote some code to do this for this Meta question; it’s not particularly clean but it should work:

function processURL(url, success){
    var id;

    if (url.indexOf('youtube.com') > -1) {
        id = url.split('/')[1].split('v=')[1].split('&')[0];
        return processYouTube(id);
    } else if (url.indexOf('youtu.be') > -1) {
        id = url.split('/')[1];
        return processYouTube(id);
    } else if (url.indexOf('vimeo.com') > -1) {
        if (url.match(/^vimeo.com\/[0-9]+/)) {
            id = url.split('/')[1];
        } else if (url.match(/^vimeo.com\/channels\/[\d\w]+#[0-9]+/)) {
            id = url.split('#')[1];
        } else if (url.match(/vimeo.com\/groups\/[\d\w]+\/videos\/[0-9]+/)) {
            id = url.split('/')[4];
        } else {
            throw new Error('Unsupported Vimeo URL');
        }

        $.ajax({
            url: 'http://vimeo.com/api/v2/video/' + id + '.json',
            dataType: 'jsonp',
            success: function(data) {
                sucess(data[0].thumbnail_large);
            }
        });
    } else {
        throw new Error('Unrecognised URL');
    }

    function processYouTube(id) {
        if (!id) {
            throw new Error('Unsupported YouTube URL');
        }

        sucess('http://i2.ytimg.com/vi/' + id + '/hqdefault.jpg');
    }
}

The function uses a callback because Vimeo API calls are asynchronous.
