[FFmpeg-user] When downloading HLS video with FFMPEG it does not download the audio

[Thiago Franklin]

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.

*I'm running the following command:*

ffmpeg.exe -i "https://teste-etv.espiritismo.tv/437602.m3u8" -codec:a
libmp3lame -b:a 96k teste-hls.mp3

*OR*

ffmpeg -i "https://appsetv.b-cdn.net/hls/437602/437602.m3u8" c copy -absf
aac_adtstoasc teste-hls.mp3

*Displays the following error when trying to download the audio:*
