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
}
});

If you want to scale the TextureView's contents, use setTransform()
. For an example, see adjustAspectRatio()
in Grafika's PlayMovieActivity class, which changes the size of the TextureView contents to match the aspect ratio of the video being played.
