Topic: Could not initialize Vapoursynth scripting

So I've installed SVP pro cause I want it to work with mpv. During installation I ticked the mpv and mpv shared library box.
However, when I try to play videos it comes up with an error:
15:46:50.160 [E]: Playback [acd08e09]: VS - Could not initialize VapourSynth scripting.

Anyone know how to fix this?

Re: Could not initialize Vapoursynth scripting

This's usually because of version conflict with other Python installations.
Do you have Python installed?

Re: Could not initialize Vapoursynth scripting

No, I didn't have python installed, but I looked into the mpv folder with my SVP installation, and it had python(3.6) there as some portable thing.

Re: Could not initialize Vapoursynth scripting

what if go to mpv64 folder and run mpv.exe manually, then drag a video file over mpv's window?

Re: Could not initialize Vapoursynth scripting

Nope, same issue. Here's my log for better info:

Re: Could not initialize Vapoursynth scripting

you'd better update to the latest version first

Re: Could not initialize Vapoursynth scripting

Hmm, updating didn't seem to fix it.

Re: Could not initialize Vapoursynth scripting

could you post the new log after update?

Re: Could not initialize Vapoursynth scripting

hey, we both know you're using cracked version and the 2nd log is just fake

Re: Could not initialize Vapoursynth scripting

Could I still get some help?

Re: Could not initialize Vapoursynth scripting

If you still have this problem, try downloading the portable version of Vapoursynth R40 from here: https://github.com/vapoursynth/vapoursy … ble-R40.7z

Extract the file vsscript.dll from that archive into your MPV folder (C:\Program Files (x86)\SVP 4\mpv64) overwriting the file that is already there. MPV is refusing to work with the newer versions of that file for some reason.
