Thanks, this worked! I replaced the key's URI to point to the local file key and added the full path to the chunks on the external network. To download I used the command "ffmpeg -protocol_whitelist file,http,https,tcp,tls,crypto -allowed_extensions ALL -i gordelicia.m3u8 -c copy gordelicia.mp4". I can make a shell script to automate all of this but it is strange that ffmpeg does not provide a easy way to set/replace the decryption key on the command line
