Generally, if you "stream" (send) me bits, they're mine to do what I want with (practically, maybe not legally). Although, if anyone could tell me how to do that with AES-SAMPLE HLS video, I'd be very happy.
Can you describe the ways you have attempted, and the bad outcome, to help focus the answer/search a little more? The 10 minutes I spent poking around to see what "AES HLS" was made it appear that a MITM proxy would straighten that problem right out, unless you are in an iTunes FairPlay-esque encrypted to your iPhone type deal, in which case I believe the math is against you

https://github.com/selsta/hlsdl should be able to do it in theory, but it looks like WideVine DRM is involved.
Someone has a Kodi plugin to make it work but Kodi doesn't support recording of any kind (?)
