I'm trying to capture an HLS stream that is seemingly encrypted with AES-128. However I can't find any key file or a URI link. The m3u8 file contains this line:
#EXT-X-KEY:METHOD=NONE
which is usually where it lists AES-128 encryption along with a URI link or value of some kind, but obviously there's nothing there, it just says "NONE". It does mention AES-128 encryption elsewhere in the m3u8 file, but still no key or link, and the m3u8 file has basically nothing else in it except for the names of the TS chunks.

FFmpeg just gives me a generic "HTTP error 403 Forbidden" msg followed by "Input/output error" when I feed it the m3u8 link so I'm not sure what that's about, or if that's the normal msg for this type of situation.

I'd post the link but it's one of those pay-type sites where you need an account with login info. If anyone could PM me or try to help in any way I'd hugely appreciate it.
