H.264/AVC software encoding for cameras

Question

Hi All,
             Please let me know, how can we activate H.264/AVC video encoding (new feature in Flash player 11 [H.264/AVC software encoding for cameras]) using actionscript 3 in AIR application, I think, it could not be by default as there are no updates available for flash builder 4.5. So, how can we pick the encoding option. Any new API or methodology for this?
Any one any idea??

H.264/AVC software encoding is not turn on by default.  You need to assign the NetStream.videoStreamSettings property an H264VideoStreamSettings object.  Here's a very simple example;
package
          import flash.display.Sprite;
          import flash.events.NetStatusEvent;
          import flash.media.Camera;
          import flash.media.H264VideoStreamSettings;
          import flash.net.NetConnection;
          import flash.net.NetStream;
          public class TestAVC extends Sprite
                    private var _nc:NetConnection;
                    private var _ns:NetStream;
                    private var _camera:Camera;
                    private var _h264Settings:H264VideoStreamSettings;
                    public function TestAVC()
                              _h264Settings = new H264VideoStreamSettings();
                              _nc = new NetConnection();
                              _nc.client = this;
                              _nc.addEventListener(NetStatusEvent.NET_STATUS, onNetStatus);
                              _nc.connect("some fms server");
                              _camera = Camera.getCamera();
                    private function onNetStatus(e:NetStatusEvent):void
                              switch (e.info.code) {
  case "NetConnection.Connect.Success":
                                                  _ns = new NetStream(_nc);
                                                  _ns.addEventListener(NetStatusEvent.NET_STATUS, onNetStatus);
                                                  _ns.client = this;
                                                  _ns.attachCamera(_camera);
                                                  _ns.videoStreamSettings = _h264Settings;
                                                  _ns.publish("testAVC");
                                                  break;
                    public function onBWDone():void {}
                    public function onMetaData(o:Object):void {}
