I have a question concerning patching scm and ps files:
Can anyone tell me where to find them? I'm not that firm with this

The other thing is: Do I have to install something to use the patch command?
I get an error message "unknown command"
To reiterate, The Knut Petersen mkvideo files are available in this
lilypond-user posting:
https://lists.gnu.org/archive/html/lilypond-user/2017-07/msg00234.html
I think this feature shows great promise. Further exploring this is high
on my LilyPond to-do list. But at this point, getting set up for the
mkvideo features seems to me like a "void your warranty" operation.
Great fun, but ideally try it on a separate copy of lilypond if you
still want to have the standard, unmodified version available. That
could involve downloading one of the Linux source or binary packages, or
doing a Git clone or checkout. All available here:
http://lilypond.org/development.html
You shouldn't need to find the scm and ps files individually. The patch
command will do that itself if properly directed. By observing the diff
file...
https://lists.gnu.org/archive/html/lilypond-user/2017-07/txtZbTxhQPWxz.txt
...you can see everything that will be changed by the patch command:
--- ./origscm/output-ps.scm 2016-11-21 05:26:10.894702197 +0100
+++ ./scm/output-ps.scm 2017-07-20 06:35:48.233783884 +0200
@@ -204,10 +204,11 @@
The file with the +++ before it is the one being changed. Below that,
the @@ shows the starting point in the file, then any line with a -
minus sign is being removed, and the ones with a + plus sign are being
added.
Now, check if the patch command is available on your system.
karlin@debian:~$ whereis patch
patch: /usr/bin/patch /usr/share/man/man1/patch.1.gz
If it just says "patch:" with no file path, then I expect it needs
installation, maybe something like this...
karlin@debian:~$ sudo apt-get install patch
...or however you are used to installing Debian packages.
Then, find the directory containing the LilyPond files. If you just
downloaded and extracted it, you can run the search from that directory
instead of doing "cd /" first.
karlin@debian:~$ cd /
karlin@debian:/$ sudo find -name output-ps.scm
On my system, the output includes this:
./mnt/sdb1/LilyDevOS/lilydevos-0.1/home/dev/lilypond-git/scm/output-ps.scm
./mnt/sdb1/lilyvideo/lilypond/usr/share/lilypond/current/scm/output-ps.scm
Yours will be different. The level above the last directory is the place
to be. When you can run the ls command and get this...
fonts ly ps python scm vim
...you are there, and ready to run patch. If you had the diff file in
the home directory, maybe something like this:
$ patch -p 1 < ~/mkvideo-lily-diff
That should change everything that needs changing for this. All
instructions here are subject to correction by list members with greater
Linux and LilyPond skills.
Follwing Knut's instructions, I was able to get the Wolf_Resignation
video produced, but none of my own projects yet. Knut? This thing really
needs a Tiny Example. Could you make a video project with just a C-major
scale or something? I love looking at other people's lilypond code for
picking up tips and inspiration, but in this case my mediocre lilypond
skills got drowned while trying to understand all the different \book
outputs at the end. I couldn't easily tell which code was needed for
video projects and which was just the Knut Petersen standard for coding
style and project structure.
