Constantly Updated m3u8 URL

[yarrak]

So, a website lets you "preview" contents (it's rent platform) and loads full film once you click play. There is timer on the page after 2-3 minutes you must refresh the page because it no longer let you watch the rest. Since it loads full movie I can grab m3u8 url via cat-catch copy N_m3u8DL-RE code and download is starting. But after that 3 minutes have passed N_m3u8DL-RE can't download new .ts fragments because supplied m3u8 URL is changed on the website. I clicked again preview it loads full movie again with fresh m3u8 url but everything inside is the same (key, key address). They use JWPlayer.

I give some randomized example (no actual link) which can give you the method and I'd like to your help how to deal with constantly changing m3u8 url? I can't disclosure the name obviously...

1st preview 1080p randomized m3u8 url:

key address:

https://randomwebsite.com/47286/files/21/01/8397152/31473-zT8vKpR2mXq9bLd-drm-aes.ism.key

Key method: AES-128

in 2nd url only red text is changed. 2nd key address is exactly the same with first one.

I can play .ts files that downloaded during preview no DRM.

You won't get the 'full' version from the 'preview'.

I got this thinking because once I load url to N_m3u8dl it shows full length of the movie and m3u8 contains all segments. Theoratically, I could download whole movie under 3 min if my internet speed is fast enough.. gigabit or something.

Show 'ts' fragment URL.

Same url goes with 1-2-3.ts.
