// this script provides a very simple way to get the m3u8/hls url to feed into VLC, MPC-HC or any other player capable of playing streams; it also offers a pre-built oneliner for ffmpeg to download said stream
// 
// works on both DE and FR and covers standard programs as well as arte concert 
// 
// other tools you should consider using are "yt-dlp" and addons such as "The Stream Detector" for Firefox
// ( https://addons.mozilla.org/en-US/firefox/addon/hls-stream-detector/ )
// 
// the initial version was based on https://gist.github.com/t3k4y/a88afc5907bca0ffaec316de9bdb8184

// if you want to get the url the second the page loads, change this from 0 to 1:
var loadonload = 0;

// do not edit below this line
