Use "yt-dlp -F mpdlink" to find out the id of audio and then download it using "yt-dlp -f audioID mpdlink"

video which is protected by an mpd

Something inside the mpd protects the video, not the mpd itself.

the video downloads just fine and i have the key to decryp it
but how to select the audio track that i want it to be downloaded
the video has 8 audio tracks
i tried this but it keeps listing the streams again
this is the audio track id i want to download
audio_aac_2736485936560_en_mp4a_3-1

yt-dlp -F audio_aac_2736485936560_en_mp4a_3-1 --allow-u --no-check-certificate mpd url

Note :
by using this command without the -F
like this
yt-dlp --allow-u --no-check-certificate mpd url
it will download the video file just ok but the audio track is only 57kb
