[rtmpdump] Adobe content protection faxs.adobe.com

[Andrea]

Hi,

I am trying to download a .mp4 protected with some adobe faxs protection.

It is inside a .m3u8 like this one

http://lb.cdn.m6web.fr/s/cu/prime/vod/protected/7/e/b/Enquete-exclusive_c11529756_Daesh-la-multinat/Enquete-exclusive_c11529756_Daesh-la-multinat_400k.mp4.m3u8

which starts like that

#EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:7
#EXT-X-PLAYLIST-TYPE:VOD
#EXT-X-FAXS-CM:URI="Enquete-exclusive_c11529756_Daesh-la-multinat_400k.mp4.drm"

#EXT-X-KEY:METHOD=AES-128,URI="faxs://faxs.adobe.com",IV=0x5a8ddab79f4fff6a8333ea8ff64d3cd4
#EXT-X-MEDIA-TIME:0.0
#EXTINF:6,
Enquete-exclusive_c11529756_Daesh-la-multinat_400k.mp4.0_6000.ts?trackid=1,2


I might be completely wrong,
is there any similarity between what rtmpdump does and this?
Note that

#EXT-X-FAXS-CM:URI="Enquete-exclusive_c11529756_Daesh-la-multinat_400k.mp4.drm"

can be downloaded and contains some data mentioning flash and adobe.

just wondering if you have a clue about it.

thanks
