help with the m3u8 link from nbc

[chanc]

When I am trying to download shows from nbc, take the following link as an example
https://www.nbc.com/today/video/toda...8-2017/3545906
I get an m3u8 link from the console
That is
https://nbcmpx-vh.akamaihd.net/i/vid...il/master.m3u8

But when I use this link to ffmpeg with a code like this :
ffmpeg -i "https://nbcmpx-vh.akamaihd.net/i/video/1000/467/170704_3545906_Today___Aug_08__2017_,25,40,18,12,7 ,4,2,00.mp4.csmil/master.m3u8" -c copy today_170808.mp4

Is there anyway to get this video downloaded ?
Thanks in advance!
