• I finally did it!
  Everything you need is here
  and it gives this

  function h264videosWithYoutubeURL(_youtubeId, _callbackOk, _callbackError)
  {
          var youtubeInfoUrl = 'http://www.youtube.com/get_video_info?video_id=' + _youtubeId;
          var request = Titanium.Network.createHTTPClient({ timeout : 10000  /* in milliseconds */});
          request.open("GET", youtubeInfoUrl);
          request.onerror = function(_event){
              if (_callbackError)
                  _callbackError({status: this.status, error:_event.error});
          };  
          request.onload = function(_event){
              var qualities = {};
              var response = this.responseText;
              var args = getURLArgs(response);
              if (!args.hasOwnProperty('url_encoded_fmt_stream_map'))
              {
                  if (_callbackError)
                      _callbackError();
              }
              else
              {
                  var fmtstring = args['url_encoded_fmt_stream_map'];
                  var fmtarray = fmtstring.split(',');
                  for(var i=0,j=fmtarray.length; i<j; i++){
                      var args2 = getURLArgs(fmtarray[i]);
                      var type = decodeURIComponent(args2['type']);
                      if (type.indexOf('mp4') >= 0)
                      {
                          var url = decodeURIComponent(args2['url']);
                          var quality = decodeURIComponent(args2['quality']);
                          qualities[quality] = url;
  
                      }
  
                  }
                  if (_callbackOk)
                      _callbackOk(qualities);
                  }
          }
          request.send();
  
  
  }
  

• See https://gist.github.com/3151702 for my quite short workaround. Native player by extracting the mp4.

• @Jonathan: My Gist still works; we experienced the same outage, but my workaround wraps around the interface, the mobile Youtube App uses. https://gist.github.com/3151702 — we're already deploying this code as workaround in our apps. (successfully). Youtube implemented several security enhancements on it's servers; so for now, I think, this workaround is the only way to get it working. Have a nice day!

• Here is a spin-off of Kenan's solution that works on both iOS and Android:

  var lib = Alloy.Globals;
  
  exports.play = function(id) {
      getVideo(id);
  };
  
  function getVideo(id) {
      var client = Ti.Network.createHTTPClient();
      client.onload = function () {
          var json = decodeURIComponent(decodeURIComponent(decodeURIComponent(decodeURIComponent(this.responseText.substring(4, this.responseText.length)))));
          var response = JSON.parse(json);
          var video = response.content.video;
          var streamUrl = video['fmt_stream_map'] ? video['fmt_stream_map'][0].url : video.stream_url;
          Ti.API.info("stream url: " + streamUrl);
          playVideo(streamUrl);
      };
      client.setRequestHeader('Referer', 'http://www.youtube.com/watch?v=' + id);
      client.setRequestHeader('User-Agent', 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_2) AppleWebKit/536.26.14 (KHTML, like Gecko) Version/6.0.1 Safari/536.26.14');
      client.open('GET', 'http://m.youtube.com/watch?ajax=1&feature=related&layout=mobile&tsp=1&&v=' + id);
      client.send();
  }
  
  function playVideo(url) {
      var win = Ti.UI.createWindow({
          title: 'Video Player',
          backButtonTitle: 'Videos',
          barColor: '#000',
          backgroundColor: '#000'
      });
      videoPlayer = Ti.Media.createVideoPlayer({
          backgroundColor: '#000',
          fullscreen: true,
          url: url,
          autoplay: true,
          scalingMode: Ti.Media.VIDEO_SCALING_ASPECT_FIT,
          mediaControlMode: Ti.Media.VIDEO_CONTROL_NONE
      });
      /*videoPlayer.addEventListener('complete', function(e) { 
          if (e.reason === 0) {
              Ti.API.info('complete exit');
              win.close();
          };
      });*/
      videoPlayer.addEventListener('fullscreen', function (e) {
          if (!e.entering) {
              Ti.API.info('fullscreen exit');
              win.close();
          }
      });
      if(!lib.constants.IS_ANDROID) {
          win.add(videoPlayer);
      }
      win.open();
  }
  

• As long as you can get the MP4 version of the file I don't think it'll be an issue. I've been adding Revsion3 videos to my app (both for Android and iPhone) and it's now working fine. It took a bit of trial and error to get the code to work across both platforms.

  On Android it will always fire up a new window.. i.e. the video isn't embedded like you can do on the iPhone.

• Unfortunately I don't have control over the media type. It may not always be an MP4.

• i have searched all the net, nothing happens, i really need to learn playing youtube videos, is this really so hard?nobody can't do that?

• : (
  @ since 2 weeks with Martin Guillon script -> HTTP-Fehler 403 (Forbidden): Der Server hat die Verarbeitung der Anforderung verweigert.

  help please.

• @ Martin Guillon
  I am newbie in Titanium Can You please post the whole code along with design to get the complete functionality i.e. running video from Youtube ..

• This code works on Android, but the format is .3GP (low quality) :

    function convert(a){
      //where "a" is video ID;
      var xhr = Ti.Network.createHTTPClient();
      xhr.setRequestHeader("Referer", "http://www.youtube.com/watch?v=" + a);
      xhr.setRequestHeader("User-Agent", "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_2) AppleWebKit/536.26.14 (KHTML, like Gecko) Version/6.0.1 Safari/536.26.14");
      xhr.open("GET", "http://m.youtube.com/watch?ajax=1&feature=related&layout=mobile&tsp=1&&v=" + a);
      xhr.onload = function () {
              x = decodeURIComponent(decodeURIComponent(decodeURIComponent(decodeURIComponent(this.responseText.substring(4, this.responseText.length)))));
              y = OS_IOS ? JSON.parse(x).content.video["fmt_stream_map"][0].url : JSON.parse(x).content.video["stream_url"];
  
              movie.url = y;
              win.add(movie);
      };
      xhr.send();
  }
  

• hi, if creating a webview? is not good?

• i figured out how to play youtube videos with a regular video player ( Titanium.Media.VideoPlayer, or native as MPMoviePlayerController) - msg me at sircambridge at gmail
