Improvement to documentation: How do you use cue files?

[MaxKellermann]

Your configuration does nothing, because all it says is that the "cue" plugin shall be enabled, but that's already the default.
The command you issued doesn't show directories; it shows only songs.
Read https://www.musicpd.org/help/ before you ask for help. Your question lacks information that is necessary to help you.

[MaxKellermann]

Would it be possible to update the documentation to explain the idea and location of the virtual directory a bit more, and perhaps add an example for the cue plugin?

Here I don't know what kind of documentation you want to have. The location of the virtuel directory is the location of the playlist file. How could an example look like? Why don't you write documentation and submit it as a PR?

Hi @MaxKellermann thank you for the quick response. The output of mpd --version is below. There's nothing suspicious in the logs. It shows I'm on version 0.22.6 (on Raspberry Pi). Should I try to install from source? (This may be a little beyond me...)

The files are in my music dir in mydir. The command mpc ls mydir works and shows

dir/file.m4b
dir/file.cue
dir/file.cue

The command mpc ls mydir/file.cue doesn't return anything (neither error, nor data; nothing in the logs). The actual listing of the music dir in the file system shows:

dir/file.m4b
dir/file.jpg
dir/file.cue

So I guess one of the 'cue' files above might be the virtual directory? But listing it doesn't yield anything - how do I access the virtual directory generated by the cue file?

The cue file looks like this:

FILE "file.m4b" MP4
TRACK 1 AUDIO
  TITLE "Chapter 01"
  INDEX 01 0:0:00
TRACK 2 AUDIO
  TITLE "Chapter 02"
  INDEX 01 12:15:42
...

I'd be very happy to make a PR on the documentation with a simple recipe on how to check use of cue files.

Your MPD version is very old and unsupported.

Hi @MaxKellermann, I've updated using the packages here: https://bobrathbone.com/raspberrypi/compiling_mpd.html and am now on version Music Player Daemon 0.23.13 (0.23.13) (see below).

I've done a rescan of the library (mpc rescan), but I get the same issue as above, i.e., as above the files are in my music dir in mydir. With the new version, the command mpc ls mydir works and shows

dir/file.m4b
dir/file.cue

(only one .cue file this time). The command mpc ls mydir/file.cue now returns an error:

MPD error: No such directory

The command mpc add mydir/file.cue returns:

error adding dir/file.cue: No such directory

The command mpc add mydir/file.m4b works, but only adds the one m4b.

The files in on drive are as before:

dir/file.m4b
dir/file.jpg
dir/file.cue

The cue file looks like this as indicated above.

Any tips?

Hi @MaxKellermann , as this issue also occurs with the latest version, would it be possible to reopen the issue? Many thanks!
