Apps resizing video using android texture view problem

[flyingbaloon]

Iam trying to animate a video rendered using texture view, the animation works fine , but when i scale the texture to a different size the media player does not scale to fit the size of the texture,the video is always playing full screen in the background and i can only see part of the video when i scale the texture
my code works fine on some android devices running android 4.0 but does not work on devices with later versions of android . heres my code for the animation kindly tell me where the problem is ..

public class MainActivity extends Activity implements TextureView.SurfaceTextureListener{
AnimationSet animset;
TextureView myTexture;
MediaPlayer mMediaPlayer;
Surface s;
int height;
static final String LogFileName = "Log";
int width;
protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);

  myTexture = new TextureView(this);
  myTexture.setSurfaceTextureListener(this);
  setContentView(myTexture);   
   }

   @Override
   public void onSurfaceTextureAvailable(SurfaceTexture arg0, int arg1,
   int arg2) {


   String mediaStorageDir = Environment.getExternalStoragePublicDirectory(
            Environment.DIRECTORY_DOWNLOADS).getAbsolutePath();
s = new Surface(arg0);

   try {
       mMediaPlayer= new MediaPlayer();
       mMediaPlayer.setSurface(s);
       mMediaPlayer.setDataSource(mediaStorageDir+"/AirIndia.mp4");
       mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
       mMediaPlayer.prepareAsync();
       mMediaPlayer.setLooping(true);
       mMediaPlayer.setOnPreparedListener(new OnPreparedListener() {
            @Override
            public void onPrepared(MediaPlayer mp) {

                mMediaPlayer.start();

            }
        });  


// to animate the texture  

     animset =new  AnimationSet(true);
     animset.addAnimation(scaling);
     animset.addAnimation(translate);
     animset.setStartOffset(20000);

  Animation fulscaling = new ScaleAnimation(1.0f, 1.3333f, 1.0f, 1.3333f);
     TranslateAnimation fulltranslate = new TranslateAnimation(
        Animation.RELATIVE_TO_SELF, 0.0f,Animation.RELATIVE_TO_SELF, -0.3333f,        0, 0.0f, 0, 0.0f);
          fulltranslate.setStartOffset(10000);

        animset.setDuration(1000);
        animset.setFillAfter(true);
        animset.setFillEnabled(true);
        fulscaling.setStartOffset(10000);

        animset.addAnimation(fulscaling);
    animset.addAnimation(fulltranslate); 

    myTexture.setAnimation(animset);


    animset.setAnimationListener(new AnimationListener() {

          @Override
          public void onAnimationEnd(Animation arg0) {

              myTexture.startAnimation(animset);
          }

          @Override
          public void onAnimationRepeat(Animation arg0) {
              // TODO Auto-generated method stub

          }

          @Override
          public void onAnimationStart(Animation arg0) {
              // TODO Auto-generated method stub

          }

      });
