pict.recycle(); mBitmap.recycle();
pict = retrieve.getFrameAtTime(frame);
mBitmap = Bitmap.createBitmap(pict, 0, 0,
pict.getWidth(), pict.getHeight(), matrix, true);
Log.e("Media", "load Frame " + frame + " ("+ (11-playSpeed)

Log.e("Media", "load Frame step 1 ");
super.setImageBitmap(mBitmap);
Log.e("Media", "load Frame step 2 ");
super.invalidate();
Log.e("Media", "load Frame step 3 ");
}
}
frame get inremented in steps of 10 , thus pict =
retrieve.getFrameAtTime(frame); loads every 10 frames
mBitmap as you can see is set to update the super.setImageBitmap()
resulting in the following logcat

My question is Why Does the frame NOT change visually. It constantly
shows the first FRAME only
Why ?
Thanks in advance
