Yes, I only identified the first #EXT-X-MAP and drop others. You can try manually editing M3u8 and use --baseUrl to download it. BTW, N_m3u8DL-CLI can not decrypt SAMPLE-AES-CTR.

Yes, it's ok i know, i use your tool to skip this "encryption" only to get the files beacause ffmpeg dont support it (or never will), but the map/pod=id is realy annoying :/
