Hello,

Every video I tried gives me an 403 when I want to download the audio stream or video stream.

Example video: https://www.youtube.com/embed/-FGrZolntqk ResourceUri for audio stream

            throw new InvalidOperationException("No audio stream detected.");
        if (videoStream == null)

            var audioPath = await DownloadMedia(audioStream, result);
            var videoPath = await DownloadMedia(videoStream, result);
            GenerateOutputFile(audioPath, videoPath, videoStream, path);

  }
