I have a couple of Polish TV streams I'd like to add to my "Live TV" list, however the way they are surfaced is via an embedded player. It looks like the web link sets up some server side session magic with a dynamically generated "session" field. For example, when I go to https://polonia.tvp.pl/sess/TVPlayer2/embed.php?ID=34414171, if I watch the traffic I can see that it gets a m3u8 uri, which I can pump into VLC and watch just fine: https://rsdt-krk201-5.tvp.pl/token/video/live/34414171/20
