Thank you very much for you kindness!
I re-crawled, and then used the code to download this time ,
Code:
ffmpeg -user-agent "Mozilla/5.0" -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?hdnea=st=1502322576~exp=1502335206~acl=/i/video/1000/467/170704_3545906_Today___Aug_08__2017_*~id=00137e73-b5b4-4f38-8080-1a2f7ebfd8a8~hmac=21b5342b2ca3521cbde6abcb98b28d01c351f04a8933f54af7d3939bfdd7c51c" -c copy today_170808.mp4
and got a different result than the previous attempts

Apparently , the code works!
But I have some other things to fix before I am able to get this video down.
How do I fix the problem mentioned which is in red in the prompt ?
Thank you !
