This is the kind of stream I am having difficulty with. When I try your code...

ffmpeg -protocol_whitelist file,udp,rtp,crypto,tcp,https,rtsp,tls -i "TS-M3U8 URL HERE" -c:a copy -c:v copy "OUTPUT FILE HERE.ts"

using my own filenames I get an error about "unable to open key file". I am not sure how to get that key file from the m3u8 file. I have read that it could be found in a cookie but also that it could be found in them m3u8 file itself.
