Thanks for sharing this! I have a Debian VM set up for this now: FreeNAS 9.10.2 -> bhyve (iohyve v0.7.7) -> Debian 8. I was able to produce the Hugo Wolf "Resignation" video. I got some font errors during the lilypond compile: "warning: no glyph for character U+9F in font [...] ./texgyreschola- [*]" (Square brackets with placeholders for brevity.) Looks my setup is choking on the German ß sharp-S thing. > mkvideo-lily-diff contains changes to an installed version of lilypond > (tested with 2.19.65, but it also > should work with much older versions).

Hmm... if everything else is the same after patching, any chance this could be included in the standard lilypond code? Or maybe that's what you have in mind, and just want more people to try it out first? I think this would be a great feature to have standard. > mkvideo requires bash, ls, sort, tail, uniq, grep, sed, usleep, bc, > gs, pdftk, > lilypond, fluidsynth, sox, ffmpeg, wc and a suitable sound font, e.g. > FluidR3_GM.sf2 All the dependencies, though... might be a bit much to include in the standard lilypond setup? Maybe that would have to be handled like Audacity does with some of their features: "If you're on Windows and want an MP3 encoder, go get this additional installer for LAME." And it turns out Debian does not have usleep but rather sleepenh. I ended up doing... ln -s /usr/bin/sleepenh /usr/bin/usleep ...as advised by an old, but apparently still valid Debian bug report. https://bugs.debian.org/223455 > 1.

I missed the soundfont advice on first reading. To statisfy the dependency for kptestpiano.sf2, I copied /usr/share/sounds/sf2/FluidR3_GM.sf2 Is there a way to set a path for the patched lilypond when running the mkvideo script? Or a definition to edit somewhere? I looked around a little in the mkvideo code, but my limited bash script skills didn't pick anything up. > If you have problems: DEBUG gives a very verbose output, clean keeps > temporary files. > > cu, > Knut Next, I'll be trying to make score videos of the "Hallelujah Chorus" from Handel's Messiah, or "Prayer of Thankful Praise" by Hal Hopson. Among my past projects, I think those are the ones that would most benefit from video scores. -- Karlin High Missouri, USA _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
