- nothing really performing I suppose. How many frames? How many fps?Seraphim's– Seraphim's2013-10-07 13:54:07 +00:00Commented Oct 7, 2013 at 13:54

You can try this to extract frame:
package com.example.androidmediametadataretriever; import android.graphics.Bitmap; import android.media.MediaMetadataRetriever; import android.os.Bundle; import android.widget.ImageView; import android.app.Activity; public class MainActivity extends Activity { String uri = "/storage/sdcard0/DCIM/100MEDIA/VIDEO0007.mp4"; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); ImageView capturedImageView = (ImageView)findViewById(R.id.capturedimage); MediaMetadataRetriever mediaMetadataRetriever = new MediaMetadataRetriever(); mediaMetadataRetriever.setDataSource(uri); Bitmap bmFrame = mediaMetadataRetriever.getFrameAtTime(5000000); //unit in microsecond capturedImageView.setImageBitmap(bmFrame); } }

Thanks for your kind support. I tried with getFrameAt(time,MediaMetadataRetriever_OPTION_CLOSEST) but i am getting null value.
