Anyone else getting the entry point errors loading the vlc plugins?
VapourSynth was built in a virtual env so I could use cython 3.0.10. libvlc-dev is installed.

I removed cython via apt and installed the latest stable via pip and vapoursynth compiled OK (with some sided warnings. )

Do I need to remove the noexcept specifier or update cython?

Is there a recommended install directory for SVP4?

How does this look for a full featured mpv install aiming to leverage the 1080TI. Any other features / optimizations to add or suggested removals? I am wanting to use the GPU and have an AMD CPU if that is relevant.
Understood I need to be careful to match the cuda toolkit and driver versions.

Currently working through the checklist for a Linux Mint 20 SVP MPV/SMPlayer install and wondering if I need to update my ICD loader.
