The script in this repository generates M3U playlists for every directory
containing audio files (mp3, m4a, aac) on an sdcard for playing on a
"SanDisk Clip Sport" mp3 player. First, put all your music files in
separate directories on your sdcard in a top-level directory called
Music. For instance if the sdcard is mounted on /mnt/music, put
music files in:
/mnt/music/Music/playlist1
/mnt/music/Music/playlist2
...
/mnt/music/Music/playlistN
Upon running ./mkplaylists.sh /mnt/music, the script will create:
/mnt/music/Music/playlist1/playlist1.m3u
/mnt/music/Music/playlist2/playlist2.m3u
...
/mnt/music/Music/playlistN/playlistN.m3u
By trial and error, it is known that M3U files on this particular device
must have DOS-based line terminators (carriage return + line feed). Thus
this script uses dos2unix. "Corrupt" playlists (with just Unix newlines)
result in playlists that appear empty to the mp3 player interface.
These devices only support playlists of at most 1000 songs:
NOTE: Maximum number of M3U playlists supported is 50 playlists. Maximum number
of files supported per playlist is 1000
