Hello:
I can login to watch some live sports games from one small video web site.
I found that the web site uses JWPlayer to play live videos, and I found the HLS source seems to be available for all browser without login. It is working for Google Chrome, Microsoft Edge, and Firfox without login.
The following is one of such URL, which I can watch live sport game:
https://bingsport.com/1proxy.php?id=g_1
Other examples like:
https://bingsport.com/1proxy.php?id=g_2
https://bingsport.com/1proxy.php?id=g_3
......
https://bingsport.com/1proxy.php?id=g_20

Depend on what time you try, in the European nights, there are always some live sports games.
I tried to use Youtube-DL.exe to download it, but I got error message:
[generic] 1proxy: Requesting header
WARNING: Falling back on generic information extractor.
[generic] 1proxy: Downloading webpage
[generic] 1proxy: Extracting information
ERROR: Unsupported URL: https://bingsport.com/1proxy.php?id=g_1
I want to know what type of live stream this URL is using, and how I can download it?
Any ideas on how to find correct software to download such live stream?
By the way, I found the web site uses JWPlayer (version 8.20.5) to play such live stream.
But I want to know how to download the live stream and save in local hard disk, not to play it with some kind of media player.
Thanks,
