Didn't find any notes with \TabStaff #123

Closed iostapyshyn closed 3 weeks ago

iostapyshyn commented 4 weeks ago

I am trying to use ly2video to generate a video with a guitar tab, but it fails with the following error message:

ERROR: Didn't find any notes; something must have gone wrong with the use of dump-spacetime-info.

Here's the minimal reproducible example:

\score {
  \new TabStaff {
    c d e f g a b c'
  }
  \layout { }
  \midi {}
}

I am trying to process it with $ ly2video -i example.ly, with LilyPond 2.24.3 (running Guile 3.0). Is there something I'm missing?

The diff below seems to fix the issue. What do you think, @aspiers?
