I am getting the same error message as LinuxBaby.

VS - Script evaluation failed:

VS - Python exception: Cache: nodes foreign to this core passed as input, improper api usage detected

I downloaded https://github.com/vapoursynth/vapoursy … R50.tar.gz from the repo's releases page instead of 

git clone https://github.com/vapoursynth/vapoursynth.git

so...:

wget https://github.com/vapoursynth/vapoursynth/archive/R50.tar.gz
tar -xvzf R50.tar.gz
cd vapoursynth-R50/
./autogen.sh
./configure
make
sudo make install
cd ..

...and it worked!

Hi. I'm trying to move away from Windows and after the entire night installing dependencies, I managed to build mpv with VapourSynth enable.
Now I am getting this error and no amount of googling has given me any advice:

Is something wrong with SVP's generated script? I have no idea how VapourSynth's scripts work... Please, help me!
