It is possible to display a video thumbnail from a URL on Android 4 and above?

Solution
Use FFmpegMediaMetadataRetriever to extract a thumbnail at the desired position: FFmpegMediaMetadataRetriever
Problem
Both of the below works fine on the emulator (2.3.3), but on a real device (Nexus S with 4.1.2) no image is shown for the thumbnail. I will also try to run it on an `Android 4 Emulator`. If I set a default `android:src` for the `ImageView`, it is not shown anymore then. This makes me think that it is replaced, but the `ImageView` is empty. ``` public class MainActivity extends Activity { ImageView img; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); img = (ImageView)findViewById(R.id.img_thumbnail); new MyAsync().execute("http://commonsware.com/misc/test.mp4"); } //This version is still not working, but it's more readable (edited: Selvin). public class MyAsync extends AsyncTask<String, Void, Bitmap>{ @Override protected Bitmap doInBackground(String... objectURL) { //return ThumbnailUtils.createVideoThumbnail(objectURL[0], Thumbnails.MINI_KIND); return ThumbnailUtils.extractThumbnail(ThumbnailUtils.createVideoThumbnail(objectURL[0], Thumbnails.MINI_KIND), 100, 100); } @Override protected void onPostExecute(Bitmap result){ img.setImageBitmap(result); } } } ``` I know that a similar question has been asked before, Displaying video thumbnails in an Android device from a remote video URL, but I have already tried this and same result. Why doesn't this work on the device and how make it work?
