    Try this Create new AsyncTask like this

    public class DownloadImage extends AsyncTask {
        ImageView bmImage;
    
        public DownloadImage(ImageView bmImage) {
            this.bmImage = (ImageView ) bmImage;
        }
    
        protected Bitmap doInBackground(String... urls) {
            Bitmap myBitmap = null;
            MediaMetadataRetriever mMRetriever = null;
            try {
                mMRetriever = new MediaMetadataRetriever();
                if (Build.VERSION.SDK_INT >= 14)
                    mMRetriever.setDataSource(urls[0], new HashMap());
                else
                    mMRetriever.setDataSource(urls[0]);
                myBitmap = mMRetriever.getFrameAtTime();
            } catch (Exception e) {
                e.printStackTrace();
    
    
            } finally {
                if (mMRetriever != null) {
                    mMRetriever.release();
                }
            }
            return myBitmap;
        }
    
        protected void onPostExecute(Bitmap result) {
            bmImage.setImageBitmap(result);
        }
    }
    

    Than call this AsyncTask like this

       new DownloadImage(YourImageView).execute("Your URL");
    

    EDIT

    Or you can also use Glide to create thumbnail of video from url

     RequestOptions requestOptions = new RequestOptions();
     requestOptions.placeholder(R.drawable.placeholder_card_view);
     requestOptions.error(R.drawable.placeholder_card_view);
    
    
      Glide.with(getContext())
           .load(path)
           .apply(requestOptions)
           .thumbnail(Glide.with(getContext()).load(path))
           .into(ivVideoThumbnail);
