need help downloading a video

[swappyison]

so i want to download a video: https://www.zee5.com/movies/details/sathamanam-bhavathi/0-0-2712
I know that simply using yt-dlp will download the video, this is not my concern.(Output video is NOT encrypted)
i want to know which m3u8/mpd link it is using since I am making my own scraper. Performing a GET request to this url:https://gwapi.zee5.com/content/details/0-0-2712?translation=en&country=IN&version=2, I found out that the response contains video url in two forms, one is mpd link(widevine encrypted) and other is m3u8(fairplay encryption).
the m3u8 file has this code:

If possible I would like to know how to decrypt the m3u8 stream.

if the m3u8 is fairplay encrypted, you'd have to crack fairplay encryption. I would just stick with the Widevine MPD

sorry, my question is how is:

yt-dlp "https://www.zee5.com/movies/details/sathamanam-bhavathi/0-0-2712"

able to download it without needing any decryption.

use the --verbose parameter on yt-dlp and check which m3u8 it downloads
