I hate that we need to cast the hash objects as a non-recognizable type in UnityScript. Oh well.

import com.adobe.serialization.json.JSON;

var loader :URLLoader = new URLLoader();

var vid : String = "qE5hpp4YaH4";
loader.load(new URLRequest("http://gdata.youtube.com/feeds/api/videos/" + vid + "?v=2&alt=json-in-script&callback=remove"))

loader.addEventListener(Event.COMPLETE, onLoaded)

function onLoaded(e:Event):void{
	var youTubeDataString : String = e.target.data
	youTubeDataString=youTubeDataString.split("remove(").join("");
	youTubeDataString=youTubeDataString.split(");").join("");
	var youTubeDataObject : Object =JSON.decode(youTubeDataString)
	trace("Title: " + youTubeDataObject.entry.title.$t)
	var thumbnails : Object = youTubeDataObject.entry.media$group.media$thumbnail;
	trace("Thumbnail: " + youTubeDataObject.entry.media$group.media$thumbnail[thumbnails.length-1].url)
	trace("Description: " + youTubeDataObject.entry.media$group.media$description.$t)
}

The thumbnail section of this code grabs the HQ version which is 480×360 and is the last entry in the response JSON’s media$thumbnail area.
