In Avisynth+, support for loading VFAPI filters has been refactored into its own plugin. The sources for VFAPI functionality are included in the repository, but compilation is disabled right now, because the "new_Splice" function (used by the VFAPI plugin) is an internal function to Avisynth and is not accessible for plugins.
To be done is to find a solution to the missing "new_Splice", adapt the source accordingly, reenable, and test the plugin with Avisynth+.
