Answer 1

inner class LoadVideoThumbnail : AsyncTask<String, Any, Bitmap>() {

    override fun doInBackground(vararg objectURL: String): Bitmap {
        //return ThumbnailUtils.createVideoThumbnail(objectURL[0], Thumbnails.MINI_KIND);
        val m = MediaMetadataRetriever()
        m.setDataSource(objectURL[0], HashMap<String, String>())
        var bm = m.getFrameAtTime(-1)
        var decoded: Bitmap? = null
        if (bm != null) {
            val stream = ByteArrayOutputStream()
            bm.compress(Bitmap.CompressFormat.PNG, 20, stream)
            decoded = BitmapFactory.decodeStream(ByteArrayInputStream(stream.toByteArray()))
        }
        return decoded!!

    }

    override fun onPostExecute(result: Bitmap) {
        //img.setImageBitmap(result);
        Glide.with(this@EditItemsBaseActivity).
                load(result)
                .listener(object:RequestListener<Bitmap, GlideDrawable> {
                    override fun onException(e: java.lang.Exception?, model: Bitmap?,
                                             target: Target<GlideDrawable>?, isFirstResource: Boolean): Boolean {
                        progresBar!!.visibility = View.GONE
                        return false
                    }

                    override fun onResourceReady(resource: GlideDrawable?, model: Bitmap?, target: Target<GlideDrawable>?, isFromMemoryCache: Boolean, isFirstResource: Boolean): Boolean {
                        progresBar!!.visibility = View.GONE
                        return false
                    }

                }).
                into(videoImageView)

    }

}

LoadVideoThumbnail().execute(videoUrl)

Answer 2

Try this Create new AsyncTask like this

public class DownloadImage extends AsyncTask<String, Void, Bitmap> {
    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<String, String>());
            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);
