Can not get frames from youtube video using FFmpegMediaMetadataRetriever

I have been trying to extract a frame from a youtube video using FFmpegMediaMetadataRetriever in my android studio project. whenever I use the youtube url inside setDataSource, the app crashes. I am totally new in android studio and haven't worked with FFmpeg before. I would appreciate if anyone can help me out. Also, I am sorry if I have asked a really silly/easy question.

import wseemann.media.FFmpegMediaMetadataRetriever;
.....

private BaseLoaderCallback mLoaderCallback = new BaseLoaderCallback(this) {
    @Override
    public void onManagerConnected(int status) {
        switch (status) {
            case LoaderCallbackInterface.SUCCESS: {
                Log.i(TAG, "OpenCV loaded successfully");
                mOpenCvCameraView.enableView();
                try {
                    initializeOpenCVDependencies();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
            break;
            default: {
                super.onManagerConnected(status);
            }
            break;
        }
    }
};


private void initializeOpenCVDependencies() throws IOException {

    tick =0;
   //extract frame at 2 second using FFmpegMediaMetadataRetriever
    FFmpegMediaMetadataRetriever mmr = new FFmpegMediaMetadataRetriever();
    mmr.setDataSource("https://youtu.be/f-ehTcWC6dc");
    Bitmap b = mmr.getFrameAtTime(2000000, FFmpegMediaMetadataRetriever.OPTION_CLOSEST);
    mmr.release();

    objMat = new MatOfPoint2f();
    sceneMat = new MatOfPoint2f();
    obj_corners = new Mat(4, 1, CvType.CV_32FC2);
    img = new Mat();
    img2 = new Mat();
}

in the build.gradle, I have added the following dependencies

dependencies {

       //FFmpegMediaMetadataRetriever dependencies
       implementation 'com.github.wseemann:FFmpegMediaMetadataRetriever:1.0.14'

       implementation project(path: ':openCVLibrary340dev')
}

error that I get is:
