I used to record M3U8 files with get_iplayer, but with the latest version I can't do that any more. Can anyone help me?
get_iplayer never produced m3u8 files, so I assume you mean MP3 files. In that case, see the FAQ list.
I use the version of 2.94
I always use this code:
get_iplayer --subtitles --get "http://www.bbc.co.uk/iplayer/episode/b01nzm6f/the-adventures-of-abney-teal-series-2-17-shadows" --vmode=hlsbest --force
and I get m3u8 from it. but it doesn't work these days, under Maintenance mode
