Suppose you want to get data for the video:-

For e.g.
http://gdata.youtube.com/feeds/api/videos/9bZkp7q19f0v=2&alt=json

alt => json or xml

Gives JSON Data as

{

    "version": "1.0",

    "encoding": "UTF-8",

    "entry": {

        "published": {

            "$t": "2012-07-15T07:46:32.000Z"

        },

        "title": {

            "$t": "PSY - GANGNAM STYLE (강남스타일) M/V"

        },

        "media$group": {

            "media$category": [

                {

                    "$t": "Music",

                    "label": "Music",

                    "scheme": "http://gdata.youtube.com/schemas/2007/categories.cat"

                }

            ],

"media$description": {

                "$t": "PSY - Gangnam Style (강남스타일) \n App Store: http://goo.gl/l9TU6\nGoogle Play: http://goo.gl/UiEn1\n\n© YG Entertainment Inc. All rights reserved.",

    },

            "yt$duration": {

                "seconds": "253"

            }

        },

        "yt$statistics": {

            "favoriteCount": "0",

            "viewCount": "1121801092"

        },

        "yt$rating": {

            "numDislikes": "523231",

            "numLikes": "6549910"
