Download m3u8 videos with docker.
Simpliy do the docker-compose.
The container will monitor the change of /playlists, which is set in compose config, and download videos into /recordings with only combining ts files into a single mkv file.
If there are changes in /playlists, the container will download every m3u8 files whose corresponding mkv file does not exist in /recordings.
Thus, when moving mkv files, please remember to delete or move the corresponding m3u8 file too. Otherwise, the mkv file will be downloaded on next /playlists change, which is duplicated and might not be the result you are expecting.
