Using Hybrid without autoloading existing VS install - GunplaXross2 - 31.01.2026
If having an existing VS install for other work, Hybrid seems to throw out errors due to plugins already being loaded or a different VS install. Is there a way to prevent Hybrid from looking for existing installs/ignoring them?
File attached too*
File "src/cython/vapoursynth.pyx", line 3114, in vapoursynth.Function.__call__
vapoursynth.Error: Plugin C:/Program Files/Hybrid/64bit/vsfilters/SourceFilter/LSmashSource/LSMASHSource.dll already loaded (systems.innocent.lsmas) from C:/Program Files/VapourSynth/plugins/LSMASHSource.dll

Hybrid does use a portable Vapoursynth (and Python), so it should not load stuff outside that scope.
I think the problem isn't really Vapoursynth, but vsViewer.
Have you tried whether vspipe works?
Seems like vsViewer is using the wrong environment.
Does the attached vsViewer binary work?
Also try with the old, whether starting Hybrid and then Tools->vsViewer and enabling "Edit->Settings->Paths->Libraries form this list are loaded prior to Windows registry or system PATH" (and hitting apply) makes a difference.

The EXE fixed it right away, thank you for that. Will this change be bundled with the dev branched, or is this a "me" problem?
RE: Using Hybrid without autoloading existing VS install - Selur - 02.02.2026
I'll think about it, will have to modify:
a. vsViewer to make the change optional
b. adjust Hybrid to call vsViewer with the new parameter

Does the attached version work for you too?
(didn't remove the loading from registry, but moved it to be a last resort)

Ps.: if it does, the changes wouldn't require additional adjustments, which would be nice.
