Improving regex for parsing YouTube / Vimeo URLs

Question

I\'ve made a function (in JavaScript) that takes an URL from either YouTube or Vimeo. It figures out the provider and ID for that particular video (demo: http://jsfiddle.net

Answer 1

Here's my attempt at the regex, which covers most updated cases:

function parseVideo(url) {
    // - Supported YouTube URL formats:
    //   - http://www.youtube.com/watch?v=My2FRPA3Gf8
    //   - http://youtu.be/My2FRPA3Gf8
    //   - https://youtube.googleapis.com/v/My2FRPA3Gf8
    // - Supported Vimeo URL formats:
    //   - http://vimeo.com/25451551
    //   - http://player.vimeo.com/video/25451551
    // - Also supports relative URLs:
    //   - //player.vimeo.com/video/25451551

    url.match(/(https?\/\/)(player.|www.)?(vimeo\.com|youtu(be\.com|\.be|be\.googleapis\.com))\/(video\/|embed\/|watch\?v=|v\/)?([A-Za-z0-9._%-]*)(\&\S+)?/);
    var type = null;
    if (RegExp.$3.indexOf('youtu') > -1) {
        type = 'youtube';
    } else if (RegExp.$3.indexOf('vimeo') > -1) {
        type = 'vimeo';
    }

    return {
        type: type,
        id: RegExp.$6
    };
}
