How to record the news from CTS in Taiwan?

[Chemist925]

Howdy, I am trying to record the stream from CTS news from Taiwan which is streamed live in youtube on this site:

https://www.youtube.com/watch?v=yUTy1U1wTwE

However I don't know if there is some sort of command line application which would let me to do that. Back in the day I used streamlink but since Windows 7 isn't supported anymore I can't use its latest version. Can someone offer me some solution?. I know there is youtube-dl but I don't know how to write the proper command for that to use, moreover. Will it work on a x-86 Windows 7 laptop?.
Help please?.
