Скачать или смотреть How to install glava on Debian 11 | OpenGL Audio Spectrum Visualizer | READ THE DESCRIPTIONS!!

The video itself is self explanatory so I didn't include any voice or text. Just notes that I lost track at some point where I tried to run glava before installing it LOL! Here are the command used (every line starts with $ so you could see where the line breaks - do not include the $ in your actual command)

1. Install dependencies
$ sudo apt-get install libgl1-mesa-dev libpulse0 libpulse-dev libxext6 libxext-dev libxrender-dev libxcomposite-dev liblua5.3-dev liblua5.3 lua-lgi lua-filesystem libobs0 libobs-dev meson build-essential gcc

2. Link all libraries
$ sudo ldconfig

3. Start cloning & build
$ git clone https://github.com/jarcode-foss/glava
$ cd glava
$ meson build --prefix /usr

4. Fix the compiler/linker, refer this page
https://github.com/jarcode-foss/glava...

5. Continue installation
$ ninja -C build
$ sudo ninja -C build install

INSTALLATION DONE!

Execute
$ glava --desktop

Edit ~/.config/glava/rc.glsl to fix screen size
Edit the glsl file modes for the one you wish to use. The modes and files are:
bars : bars.glsl
circle : circle.glsl
graph : graph.glsl
radial : radial.glsl
wave : wave.glsl

To execute multiple glava instance, you can execute the first one as usual and for the second one, use --force-mod options like this, for radial glava:
$ glava --desktop --force-mod=radial

Another method for multiple glava instance is to load another 'rc' file. First copy the rc.glsl file to another name for example myrc.glsl and in that file, replace the "#request mod bars" to any mode for example "#request mod circle". Save the file and execute using --entry flag and specifying your rc file like this:
$ glava --desktop --entry=myrc.glsl

That's all. Enjoy and do let me know if you have any difficulties regarding glava.
