Getting the number of frames from a video in Android
- by Jay Patel
I want to get the number of frames from a video. I'm using the following code:
package com.vidualtest;
import java.io.File;
import java.io.FileDescriptor;
import android.app.Activity;
import android.graphics.Bitmap;
import android.media.MediaMetadataRetriever;
import android.os.Bundle;
import android.os.Environment;
import android.widget.ImageView;
public class VidualTestActivity extends Activity {
/** Called when the activity is first created. */
File file;
ImageView img;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
img = (ImageView) findViewById(R.id.img);
File sdcard = Environment.getExternalStorageDirectory();
file = new File(sdcard, "myvid.mp4");
MediaMetadataRetriever retriever = new MediaMetadataRetriever();
try {
retriever.setDataSource(file.getAbsolutePath());
img.setImageBitmap(retriever.getFrameAtTime(10000,MediaMetadataRetriever.OPTION_CLOSEST));
} catch (IllegalArgumentException ex) {
ex.printStackTrace();
} catch (RuntimeException ex) {
ex.printStackTrace();
} finally {
try {
retriever.release();
} catch (RuntimeException ex) {
}
}
}
}
In getFrameAtTime() I'm passing different static time values like 10000, 20000, etc. in milliseconds, but still I'm getting the same frame from the video. My goal is to get different frames with a different time interval.
