android capture video frame

Question

I need to get a frame of a video file (it may be on sdcard, cache dir or app dir). I have package android.media in my application and inside I have class MediaMetadataRetrie

Answer 1

so is there a specific way to get the frame from video as

 File sdcard = Environment.getExternalStorageDirectory();
 File file = new File(sdcard, "myvideo.mp4");

Answer 2

Try this, I've used it and its working

public static Bitmap getVideoFrame(Context context, Uri uri) {
    MediaMetadataRetriever retriever = new MediaMetadataRetriever();
    try {
        retriever.setDataSource(uri.toString(),new HashMap<String, String>());
        return retriever.getFrameAtTime();
    } catch (IllegalArgumentException ex) {
        ex.printStackTrace();
    } catch (RuntimeException ex) {
        ex.printStackTrace();
    } finally {
        try {
            retriever.release();
        } catch (RuntimeException ex) {
        }
    }
    return null;
}

In place of uri you can directly pass your url .
