[FFmpeg-user] How to download encrypted m3u8 providing the key?

[Matheus Silva]

Guys, how can I download from an encrypted m3u8 but that the key's URI is
no longer available? Obviously I downloaded the key previously, a 16 byte
file (that I get the hex string using "xxd -p"), I tried the following
using the cryptokey parameter but ffmpeg keeps trying to do the decryption
using the key URI provided in the m3u8 file. https://pastebin.com/SNA0CAJ2
