Topic: SVP on Linux stopped working after the vapoursynth R75 update

It's not that the SVP can't be started as an application but it's that it doesn't "inject" itself into mpv and no interpolation is done. In the log there is only 1 error: Playback [1cc060e0]: VS - Could not initialize VapourSynth scripting.

The person here https://gist.github.com/tomkabel/d3d05d … 6773735463 apparently has a solution but it's a bit over my head. Can someone smarter then me pls help?

If too complex, you can try to install Codex and ask it to debug and fix VapourSynth on your system:

Re: SVP on Linux stopped working after the vapoursynth R75 update

Terrible advice from flowreen91.
The gist you linked to fixes a different issue.
I fixed it on my Arch machine somehow but I don't really know what of the things I did, fixed it.

First I used the 

vapoursynth check-env

command and I could see that the VSSCRIPT_PATH was not set.

So I executed 

vapoursynth get-vsscript

and set the output of it as the VSSCRIPT_PATH environment variable.
It didn't seem to fix the issue even after restarting SVP, but after a computer restart it worked.
