Vapoursynth

[ChaosKing]

Hmm so installed R46 32+64bit in a vm, only per user installation. 32 first then 64. But only the 32bit version seems to work. (I also restarted the pc)

What can I do to "debug" this further?

EDIT
vs 32 has no vsvfw.dll?

Re-install of VS64 didn't help.

I uninstalled Vapoursynth and Python completely.
Then installed Python 3.7.1 followed by Vapoursynth 64-R46
Worked fine
Then I upgraded Python to 3.7.3
This way you get to select per user or all users mode

I tested this in a clean VM and vsvfw.dll is installed properly.

Loading the module also worked fine in both cases. I have no idea what you're doing wrong.

Import notice regarding installs:

PYTHON FROM THE MS STORE DOES NOT WORK

Installing the Python module with the "--user" option in pip ALSO DOES NOT WORK (for example if you want to have VapourSynth in multiple Python environments)

I think I'll finally look into the possibility of (optionally) installing python.

[Boulder]

Because of the "not installed for all users" problem, I uninstalled Python, reinstalled 3.7.3 for all users and then updated VS to R46 (64-bit). Now when I try to import a function, I just get an error "Python exception: No module named 'resamplehq'". In registry, the Python path seems ok and also all my .py files are in their usual location, in C:\Program Files\Python37\Lib\site-packages\vapoursynth.

EDIT: Looks like it's missing the __init__.py file from that Python directory?

I tested it again. Fresh installation in a VM with windows Pro 1903 x64 (created by the MediaCreationTool1903.exe tool from ms)

Vapoursynth 32 didn't work after installing it as a per user installation.

(watch with 1.5x speed ;-))

I tried exactly the same thing on win10 1903 x64 home and it worked. I did install all updates first but that's the only thing that's possibly different.

Can you verify that you have the vs2019 (or possibly 2017) installed? Not having it could make it fail to load I guess.

[ChaosKing]

Yep that was it. After installing vcredist x86 2019 (14.21.xxx) it worked.

EDIT0:
And the runtimes are not shown in this installer bcs they can't be installed with user, rights!?



EDIT1
And I think there is a python installer bug or maybe I'm understanding it wrong. Vapoursynth detects it as a "per user installation" and not "for everyone".


EDIT2:
OK I can click on "Install for all users" in customize installation. So python launcher and python are two seperate things I guess!?
The thing is, on my PC it shows always the "for all users" option by default.

Is there any way to make the 64-bit R46 installation work properly? R45 also seems to create a symlink to that Python directory and installs a .pyd file there as well. Installation of R46 didn't do either of those things.

[ChaosKing]

It seems that r46 just copies the dll instead of linking it. A reinstall does not help? You could try the diagnose function in vsrepogui to see which plugin folder is used and if it shows any problems.

I stopped linking because:
1. You need elevated privileges to create links
2. The Python bits are now installed as a normal package using pip and it doesn't really do links either

You should never have put things in the vapoursynth subdir. That was reserved for VS and nothing else. Make your own directory if you want to do things that way or simply let VSRepo stuff everything into the right place...

I think that once it was required to put your .py files containing your own VS functions under site-packages to get them to autoload so you could just import them in your script. It has worked perfectly fine until R46, hence the confusion.

Anyone maintaining some build script for all the plugins for Linux (Debian based systems)?

[ChaosKing]

There was a ppa by djcj but it seem to be gone. See here (and sublinks) https://github.com/vapoursynth/vapoursynth/issues/455

EDIT his git repo: https://github.com/darealshinji/vapoursynth-plugins

[Selur]

@ChaosKing: I know about djcjs repository problem is it doesn't get updated any more (even the repository is 'archived'), I spoke with him and he's trying to make a 'build' script for all the filters, but I was wondering if somebody already did that and may be shared it with others.

For those interested in the issue: https://github.com/darealshinji/scri.../master/Hybrid (currently not 'finished' or 'well tested', but probably helpful)

Got an issue on Linux, regarding:

• VSFilter https://github.com/HomeOfVapourSynthEvolution/VSFilter
• VsFilterMod: https://github.com/sorayuki/VSFilterMod
• xy-VSFilter: https://github.com/HomeOfVapourSynthEvolution/

all of them seem to be Windows only. Does anyone know how and if theses can be compiled on Linux?

VSFilter will always be windows only due to how it's coded. Use Subtext which is included or any other libass based alternative (if there is one).

[Selur]

okay, thanks for the info.

Is there a max speed limit set in vapoursynth? I'm testing out my new cpu with source filter like ffms2 on my dvd source, and the max speed I got is 1800 fps, while the same ffms2 in avisynth reaches 5200 fps.
