help: can't play this stream as of recently

[utuxia]

I was able to play this stream fine a few days ago.

$ ffmpeg -i http://nflioslivesvg2-i.akamaihd.net/hls/live/221521/nflioslive/2015HackerNow_w99d9_g.m3u8 -c copy test.m3u8

Can anyone figure out what has changed?

Manifest file is: http://nflioslivesvg2-i.akamaihd.net...Now_w99d9.m3u8

Stream is unprotcted so can be downloaded via IDM directly... m3u8 need may be cookie header or something not sure... BIEZOM will tell you about the header values .. but use IDM if you just wanna download the stream...

I need to be able to play it with ffmpeg.

I'm not sure what IDM is
