Thanks Vadim, I've found that command in lilypond.py, so I'm starting to
figure out what's happening.
I think the problem is that the command is not correct.
If you check the LilyPond documentation (either 2.12 or 2.13) you can
read:
-o,--output=FILE
Set the default output file to FILE. The appropriate suffix will be
added (e.g. .pdf for pdf
So -o specifies a file, not a directory.
Am I missing something?
If you use lilypond-book instead of lilypond, you can use -o as output
directory.
Maybe lilypond-book could be a better tool for writing music
documentation, as its aim is integrating text and music.
For example, lilypond documentation is compiled using lilypond-book and
texinfo.

Thanks!
I put him in CC, just in case he's not subscribed to the list.
I've tried to change this line in lilypond.py:
lilypond_args += ['-dbackend=eps', '-dno-gs-load-fonts',
'-dinclude-eps-fonts',
# '-o', tempdir, '--png']
to something like:
lilypond_args += ['--png', '-dpreview']
which works fine in a terminal, but not in sphinx.
The extension requires the temporary directory: '-o', tempdir
Unfortunately, lilypond seems to need the path of a file.
Should I substitute tempdir with something else?
I'm not a developer so I beg your pardon in advance in case I said too
much stupid things :)
Regards,
Federico
