Decrypt .ts files (AES-128)

[Broken1334]

Hi!
I have some downloaded files (.ts, .m3u8, .key) and I want to convert them into something watchable. How can I do it?

.m3u8 file:

#EXTM3U
#EXT-X-VERSION:3
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-ALLOW-CACHE:YES
#EXT-X-KEY:METHOD=AES-128,URI="9215d654965805dada3ac5327130c1ef_1.key",IV=0xed3169b1ceda974150c7022b5d04c3bc
