yt-dlp mp4 decrypted m4a audio cant be decrypted with the keys?

[heroinpigeon]

hey all im using mp4decrypt it works fine on the mp4 video but when it comes to the audio its still encrypted

mp4decrypt --key 001904137db4547185dba6e445a127f8:adf29227248b185ffd1eb23ece28f592 --key ba0897ea5f3356d1aff4dd7e077b6242:58b4a30c58e494040e4391bfc65f80b7 "Episode 101 [JpYJTNs_mz4].f150.m4a" "FTS S01E01.m4a"

this in theory should work if im thinking correct its the only two keys that are there if someone has experiance with decrypting m4a from yt-dlp please let me know what im doing wrong.

edit i think there maybe a deeper problem i tried to use this when i grabbed the video as a webm

Hard to help without a link to the video.

update: it was yt-dlp being bugged i simply reinstalled it and now the key works with the same command, thanks for all who read this.

basically if you have the same issue i had above you will need to check yt-dlp isnt outdated or bugged.
