title: When downloading HLS video with FFMPEG it does not download the audio
body: <p>I have a problem, when I try to download an HLS video with FFMPEG, it downloads the video track, but it doesn't find the AUDIO. When running the HLS .m3u8 file in a player, it plays normally, audio and video, but when trying to download, it shows an error message saying that the audio cannot be found.</p>
  <p><strong>I'm running the following command:</strong></p>
  <p>ffmpeg.exe -i &quot;https://teste-etv.espiritismo.tv/437602.m3u8&quot; -codec:a libmp3lame -b:a 96k teste-hls.mp3</p>
  <p><strong>Displays the following error when trying to download the audio:</strong></p>
