YouTube video support

I just spent a few hours integrating YouTube support for Video.js. It does have support for YouTube per https://github.com/videojs/video.js/wiki/Plugins.

You'll find the js plugin here https://github.com/eXon/videojs-youtube (<< you'll need to download this)

You have to load the js in with drupal_add_js at some point in the page rendering. I'll post my sample code below.

I integrated the ability within the formatter to pass a string to the data-setup attribute of the video tag. WARNING! Because this is typically an admin specific access point and you're pretty much passing a small chunk of javascript in there is nothing filtering it. Check_plain isn't what we would want. Maybe filter_xss to prevent full scripts? I couldn't think of a good solution for security at the time. It may be a non issue since having access to set formatter settings is pretty much an admin thing. :)

So here's the steps.

1. Apply the attached patch. It was created on 3.x-dev at commit 6bd2beb6dd26d62bc3dd42e133c82a80c912ef09
2. Paste the following into the formatter at Manage Display settings for the given field. Yes, it does work with media_youtube module.

"techOrder": ["youtube"], "src": "$url"

3. Make sure you're loading vjs.youtube.js when needed. Here's my code. I only load the js file on nodes of type 'youtube'.

function mymodule_preprocess_page(&$vars) {
  // Adding vjs.youtube.js plugin for video.js
  if ($vars['node']->type == 'youtube') {
    $videojs_youtube = 'sites/all/libraries/vjs.youtube.js';
    if (!file_exists($videojs_youtube) && $vars['is_admin'] ) {
      drupal_set_message(t("Uh oh! VideoJS can't play YouTube! Missing vjs.youtube.js"), 'error');
      return;
    }
    // Chrome has an issue with playing YouTube via VideoJS
    // htt ps://code.google.com/p/chromium/issues/detail?id=17325
    drupal_add_js($videojs_youtube, 'file');
  }
}

Note above that I stuck vjs.youtube.js within sites/all/libraries/

Also note, that Chrome seems to have an issue with playing YouTube videos - see code comment (had to put a space in the url because of the text format converting urls)

Enjoy testing!

Jorrit, if you want me to push my modified branch up to my github repo so you can pull from it (if desired), just let me know.
