MediaMetadataRetriever.getFrameAtTime() returns only first frame

Question

I have extracted frames from a video using MetadataRetriever, and have stored all images in an ArrayList. I want to store all of them on an SD car

Answer 1

Just convert your milliseconds to micro because getFrameAt get data in milliseconds

1 miliseconds have 1000 microseconds..


for(int i=1000000;i

then your problem is solved..

I created it according to my need.

public class MainActivity extends Activity
{
    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        File videoFile=new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/screenshots/","myvideo.mp4");

        Uri videoFileUri=Uri.parse(videoFile.toString());

        MediaMetadataRetriever retriever = new MediaMetadataRetriever();
        retriever.setDataSource(videoFile.getAbsolutePath());
        ArrayList rev=new ArrayList();

        //Create a new Media Player
        MediaPlayer mp = MediaPlayer.create(getBaseContext(), videoFileUri);

        int millis = mp.getDuration();

        for(int i=1000000;i
