I just rebuild standard ffmpeg («ffmpeg-5.1.3-3.fc37.src.rpm»), enabling «--enable-avisynth» in spec file, install it,
and rebuild standart mpv («mpv-0.35.1-2.fc37.src.rpm»), linking to this ffmpeg.

And same issue persists (ok — ColorBars, not OK — FFMS2).

What is the output of

Code:
ls ~/.avisynth ~/.local/lib/avisynth ~/.local/lib64/avisynth /usr/lib64/avisynth /usr/local/lib/avisynth /usr/local/lib64/avisynth

You don't have libffms2 in any of the autoload paths. And implicitly speaking, trying to rely on ensuring you're using the correct absolute path every time with LoadPlugin is rather fragile and very easy to make mistakes with.

Code:
ln -s /usr/local/lib64/libffms2.so /usr/local/lib64/avisynth/libffms2.so

+ «ffplay» from rebuilded «ffmpeg-5.1.3-3.fc37.src.rpm» also works
with ColorBars, and not works with FFMS2

Yes, but I provided absolute path to libffms, and strace logs show that libffms was found.

Of course, I just wish to make it work somehow

Quote:
Code:
ln -s /usr/local/lib64/libffms2.so /usr/local/lib64/avisynth/libffms2.so
«Libffms» selfinstalled «make install» to «/usr/local/lib», so
I added symlink

Code:
ln -s /usr/local/lib/libffms2.so /usr/local/lib64/avisynth/libffms2.so
and nothing changed — it obviously found libffms2.so
(mpv-avisynth-ffms-not-ok-after-symlinking.strace)

Code:
…

2191774 openat(AT_FDCWD, "/usr/local/lib64/avisynth/libconvertstacked.so", O_RDONLY|O_CLOEXEC) = 10

but something wrong happened.

What versions of AVISynth and FFMS work together for you?

git master of both AviSynth+ (r4003 / fc5b9bc41fd47001b7da39ea777d29c0ede2a2a7) and FFMS2 (ef243ab40b8d4b6d18874c6cef0da1a2f55a6a45), as well as the standard HEAD of the FFMS2 C-plugin (https://github.com/qyot27/ffms2_cplu...4669bb30db4828). Fedora 38 x86_64.



(libffms2.so.5.0.0 in /usr/local/lib is the upstream autotools buildsystem, libffms2.so.3.1.1 in /usr/local/lib64 is the C-plugin, built by meson)

I aligned by versions with you on AVS+, FFMS2, MPV — same problem.

Probably something magicly broken on my box, I will try to install FC38 on other laptop, to absolutely reproduce your setup (how did you build MPV?)

Cannot get why we need «FFMS2 C-plugin» → I just tried to use it as AVS+ plugin but get

Code:
[ffmpeg/demuxer] avisynth: '/usr/local/lib64/avisynth/libffms2.so' cannot be used as a plugin for AviSynth.
[ffmpeg/demuxer] (./test04.avs, line 4)
[lavf] avformat_open_input() failed
Failed to recognize file format.

The meson buildsystem doesn't build any of plugin interfaces by default, it's just the plain library. -Davisynth-c=enabled turns on the C-plugin.

mpv was built by fetching the builddeps, and then just
Code:
PKG_CONFIG_PATH=/path/to/ffmpeg-avs/lib/pkgconfig meson setup ../ -Dsdl2=enabled

Thank you very much!

Finally I get my example working!

I build
1) FFMPEG with AVS,
Code:
./configure --prefix=$HOME/ffmpeg_build --enable-gpl --enable-version3 --disable-doc --disable-debug --enable-pic --enable-avisynth --enable-ffplay --enable-shared --disable-static
2) MPV
Code:
PKG_CONFIG_PATH=/home/stas/ffmpeg_build/lib/pkgconfig meson setup ../ -Dsdl2=enabled
and FFMS2

Code:
PKG_CONFIG_PATH=/home/stas/ffmpeg_build/lib/pkgconfig CPPFLAGS=-I/usr/local/include/avisynth LDFLAGS=-L/usr/local/lib  ./configure --enable-avisynth
linked to same FFMPEG with AVS.

Looks my problem was because FFMS2 was linked to different version of FFMPEG.
