RE: No preview window - Miranda - 18.07.2025

I can't get the viewer to stay open long enough, and I can't work out how to use the f5 option? Seems like Hybrid is messed up, and I'm not sure what to do to fix it.

RE: No preview window - Selur - 18.07.2025

Got an old laptop which still runs Windows 10 Pro, I updated it (version 19045.6093) and installed the latest Hybrid dev.
Vapoursynth works fine there, so it's likely not a general Windows 10 update issue.

Uninstall Hybrid with settings.
Double check that "Program Files/Hybrid" (or where you installed Hybrid) actually got deleted.
Also check that 'C:\Users\USERNAME\AppData\Roaming\hybrid' got deleted.
Reinstall Hybrid.
If that does not help, check if you installed Vapoursynth on your system (this will cause problems).

If you open vsViewer (Tools->vsViewer), enter:
import vapoursynth as vs
core = vs.core
import site
clip = core.std.BlankClip()
clip = core.text.Text(clip, str(core))
clip.set_output()
then press 'F5' it should either show a preview window or show an error message.

When I open Tools -> Viewer I see a list of connected apps. I then click on the vSViewer box and a folder opens, but no viewer.

You should see:

when if you press vsViewer, you should see:

Then you should change the text there to:
import vapoursynth as vs
core = vs.core
import site
clip = core.std.BlankClip()
clip = core.text.Text(clip, str(core))
clip.set_output()
and press 'F5'.

I just get a view of what's in the folder.

RE: No preview window - Selur - 18.07.2025

What folder are you writing of?
Your Hybrid install has a Hybrid/64bit/Vapoursynth folder with vsViewer.exe in it, right?

RE: No preview window - Miranda - 18.07.2025

C: / Program Files / Hybrid / 64 / Vapoursynth / vsViewer -  is installed

RE: No preview window - Selur - 18.07.2025

Okay, that at least answers the second question.
C: / Program Files / Hybrid / 64 / Vapoursynth / vsViewer
I assume it's
C:/Program Files/Hybrid/64bit/Vapoursynth/vsViewer.exe
(without the white spaces, '64bit' instead of '64' and 'vsViewer.exe' instead of 'vsViewer')
So what happens if you start vsViewer from there?

Failed to open, then it opens with the message: Vapoursynth plugins manager - failed to load Vapoursynth library. Please set up the library search paths in settings.
