Hello:
I found one of the soccer games web pages, the following useful information:

<script src='https://client.1proxy.xyz/socket.io/socket.io.js'></script>

var socket = io("wss://client.1proxy.xyz");
socket.on("connect", () => {
socket.emit("d", videoId);
});
var videoId = getParameterByName("id");
var country = getParameterByName("country");
var playerInstance = jwplayer("mediaplayer");
playerInstance.setup({
"playlist": [
{
"sources": [
{
"default": false,
"type": "hls",
"file": https://m3u8.1proxy.xyz/media/${videoId}/playlist.m3u8,
"label": "0"
}
]
}
],
primary: "html5",
hlshtml: true,
autostart: true,
mute: false,
width: "100%",
height: "100vh",
liveTimeout: 10000
});

I can see that the web site is using jwplayer (version 8.20.5) to play live HLS stream, but the stream seems coming from a socket.io server (secure websocket) at: wss://client.1proxy.xyz

One of such HLS m3u8 link is like this: https://m3u8.1proxy.xyz/media/g_12/playlist.m3u8
So, the {videoId} is g_12.
I have tried to use Youtube-DL to download some m3u8 link, but failed, try using Edge Addon: Video DownloadHelper, also failed.
I want to know if I can try to download HLS directly from the WSS server:
wss://client.1proxy.xyz
I don't know much about jwplayer, I want to know if I can download HLS from jwplayer, and save in local disk.
Thanks,
