There is no function named 'AviSource'

[jonechkon]

Hello,
I'm trying to use avisynthplus on Arch linux.
Have tried installing it from official repositories and AUR (3.7.2).
Showing the version in VLC player works, but when I try to open an .avi with

AviSource("file.avi")

i only get

[avisynth @ 0x561f9cdde540] Script error: There is no function named 'AviSource'.

Same for WavSource and FmpegSource2.

Any suggestions would be much appreciated.

Thanks and greetings

FFmpegSource2 requires the ffms2 package, although per issue #194, it's probably a better idea to have a minimal (read: muxers/encoders disabled) static version of FFmpeg installed somewhere in a custom prefix to build FFMS2 against because of shared builds of FFmpeg conflicting with themselves. Or just use avs2yuv to pipe into whatever program you want to use.

The same thing also applies to the filters in LSMASHSource - minimal static FFmpeg is recommended to avoid linking conflicts.

AVISource/WAVSource is exclusive to Windows, as it uses Video for Windows to open the files.

Note: If you will attempt to take @qyot27's advice you must compile lsmash as:

diff --git a/configure b/configure
index de5faed..0a963c1 100755
--- a/configure
+++ b/configure

 SO_LDFLAGS='-shared -Wl,-soname,$@ -Wl,--version-script,liblsmash.ver'

./configure # --prefix=/opt
make -j $(nproc) install install-lib

You can then compile LSMASHSource with:

# PKG_CONFIG_PATH=/opt/lib/pkgconfig
meson setup build # -Dprefix=/opt
(cd build; ninja install)

You can then finally use AviSynth+. I don't think the lack of AviSource on GNU/Linux is particularly well documented.
