%description
libplacebo is essentially the core rendering algorithms and ideas of
mpv turned into a library. This grew out of an interest to accomplish
the following goals:

- Clean up mpv's internal API and make it reusable for other projects.
- Provide a standard library of useful GPU-accelerated image processing
  primitives based on GLSL, so projects like VLC or Firefox can use them
  without incurring a heavy dependency on `libmpv`.
- Rewrite core parts of mpv's GPU-accelerated video renderer on top of
  redesigned abstractions. (Basically, I wanted to eliminate code smell
  like `shader_cache.c` and totally redesign `gpu/video.c`)
