I want to use an old TV set with an old RPi1 to display a news channel from a service I already have a valid subscription to.

The RPi should only display the stream using ffplay, for example. In fact, I wish I didn’t have any mouse or keyboard connected to it.

On the News Channel page, which is accessed with proper authentication, I can use the Inspection Panel to obtain m3u8 for the live broadcast. It is the playlist.m3u8 selected in the screenshot.

However, the playlist URL changes every 24 hours or so.

Is there a way to write a program to get this URL without having to manually copy and paste every change that occurs?

I don’t really understand how live streaming works.

I also know I’m not providing much information now nor what kind of information I should provide for help. So please be kind…
