Can't use Hysteria due to error 193/0x000012f

[Troc]

I was trying to follow a guide I found for Vapoursynth and it recommends using Hysteria. Naturally, I downloaded the latest version from this Github page: https://github.com/Irrational-Encoding-Wizardry/vapoursynth-Hysteria

Then I added this to my script:

core.std.LoadPlugin("C:\Program Files\VapourSynth\plugins\hysteria.py")

That line errored out with 0x000012f as a Windows error and then the script editor told me "GetLastError() returned 193"
I looked for the meaning of both. The Windows error appears to mean a corrupt dll or some other mismatch and the googling the script editor error gave me a link to a thread where someone said it's a problem with importing a 32 bit filter into 64 bit program or vice versa. I'm using 64 bit Vapoursynth.

What am I supposed to do at this point? I didn't find a 64 bit Hysteria and loading the older Avisynth version of the filter with core.avs.LoadPlugin didn't work either.

Also, Vapoursynth doesn't detect Bifrost either, despite it being right there in the plugins folder. There's a libbifrost.dll and the line "core.bifrost.Bifrost(video, interlaced=True)" just resulted in "No attribute with the name bifrost exists." The error stayed when I changed the DLL name to just bifrost.dll.

core.std.LoadPlugin("C:\Program Files\VapourSynth\plugins\hysteria.py")



.py are scripts, not plugins. It's analagous to an .avs vs. .dll in avisynth - where an .avs is a script where you Import, and a plugin is a .dll where you use LoadPlugin. But unlike avisynth, you place they .py scripts in the site-packages folder for vapoursynth , not the plugins folder. You can give it a namespace like "hy" if you want

e.g.

It will look something like this

.
.
import hysteria as hy
clip = hy.Hysteria(clip, showmask=True)
.
.

Try closing vsedit and restarting - If you're using vsedit, and you added the plugin after you already opened vsedit, it won't be autoloaded

You can also try loading plugin manually
