    FileOutputStream fos;
    // String path ="data/data/com.focusmedica.eyeactivity/files/Images" +    filename;

From the android here you can get snapshot or frame of video view.

You can try this code to get the videoview frame.

    public static Bitmap createVideoThumbnail(Context context, Uri uri, int i)
    {
     MediaMetadataRetriever mediametadataretriever = new MediaMetadataRetriever();

try {
    mediametadataretriever.setDataSource(context, uri);
    Bitmap bitmap = mediametadataretriever.getFrameAtTime(-1L);
    if(null != bitmap)
    {
        int j = getThumbnailSize(context, i);
        return ThumbnailUtils.extractThumbnail(bitmap, j, j, 2);
    }
    return bitmap;
} catch (Throwable t) {
    // TODO log
    return null;
} finally {
    try
    {
        mediametadataretriever.release();
    }
    catch(RuntimeException e) { }
    }
}

you can make use of this method according to your need.

@GvSharma can you tell what is **getThumbnailSize** – Gowthaman M Jun 14 '18 at 12:48
@GowthamanM, its a method to resize the height and width of bitmap. – GvSharma Jul 25 '18 at 05:50

I have an alternative solution to replace the getFrameAt method of Android MediaMetadataRetriever. AV_FrameCapture uses MediaCodec to decode the video frame and use OpenGL to convert the video frame as RGB Bitmap. As Android MediaMetadataRetriever does not guarantee to return a result when calling getFrameAtTime, this AV_FrameCapture can be used to extract a frame of video with accuracy.
