Was looking in my termux packages to see if I can enable vulkan filters in ffmpeg (not yet), but found this library https://github.com/g-truc/glm ==== OpenGL Mathematics <http://glm.g-truc.net/> (*GLM*) is a header only C++ mathematics library for graphics software based on the OpenGL Shading Language (GLSL) specifications <https://www.opengl.org/registry/doc/GLSLangSpec.4.50.diff.pdf>. *GLM* provides classes and functions designed and implemented with the same naming conventions and functionality than *GLSL* so that anyone who knows *GLSL*, can use *GLM* as well in C++. === might be useful for someone ... vulkan filters in ffmpeg need some glsl and shader-related packages not in termux yet https://bugs.gentoo.org/750260 Vulkan video (decode) seems to be existing in some unreleased branches https://themaister.net/blog/2023/01/05/vulkan-video-shenanigans-ffmpeg-radv-...
