Need help to get started

[karasu]

Hi,
I just installed VpourSynth on linux and I wish to use nnedi3, but I need help.

I tried the 'getting started' script in the official doc and it's working, I used vspipe with ffplay.

now I want to use nnedi3 as deinterlacer, however I can't load the nnedi3 plugin.

I installed nnedi3_weights from the PPA

How should I load nnedi3 in my script?
I read through http://www.vapoursynth.com/doc/autoloading.html but I don't understand what I have to do to have autoloading working.


Also, afterwards I'd like to test the nnedi3 2x scaler on some PNG. I believe VapourSynth can be used with imagemagick, can you help me to write a script for that?

Thanks

What happens when you try to load libnnedi3.so?

import vapoursynth as vs

core = vs.get_core()

core.std.LoadPlugin("/some/place/libnnedi3.so")


You don't have to do anything to make autoloading work. It works out of the box. You can configure the folders where VapourSynth looks for plugins when autoloading them, if you want.

You can just copy your plugins to the same folder where libvivtc.so is, but that probably requires root. Or you can set up a folder in your own $HOME, as described in the document you linked.


import vapoursynth as vs

core = vs.get_core()

# It will be core.imwrif.Read, if your ImageMagick is configured with HDRI.
image = core.imwri.Read("/some/place/image.png")

image = core.nnedi3.nnedi3(image, field=0, dh=True)
image = core.std.Transpose(image)
image = core.nnedi3.nnedi3(image, field=0, dh=True)
image = core.std.Transpose(image)

After this you may want to use a resizer to shift the image a bit, because nnedi3 doesn't preserve the center.

nnedi3_rpow2 (http://forum.doom9.org/showthread.php?t=172652) takes care of the shift for you, but you have to import the script.

Thanks jackoneill,

I thought nnedi3 was included, so I have to compile it from here?
https://github.com/jpsdr/NNEDI3

No, from here: https://github.com/dubhater/vapoursynth-nnedi3
http://www.vapoursynth.com/doc/pluginlist.html is a good place to look for plug-ins and scripts.

Thanks for the help.

I cloned the repo and tried to compile vapoursynth-nnedi3 :
http://pastebin.com/Tmq78Fxi

It did not produce a libnnedi3.so, so I tried to load the libnnedi3.la in my script

vapoursynth.Error: Failed to load /home/karasu/Dev/vapoursynth-nnedi3/libnnedi3.la. Error given: /home/karasu/Dev/vapoursynth-nnedi3/libnnedi3.la: invalid ELF header

Was something wrong during compilation?


also as a side note :

- in VSEdit ctrl-s does not work, I have to manually select file>save script

- the ~/ shortcut for home directory does not work in the scripts, absolute path seems to be mandatory

Ctrl+S does work. But you need to press it in the edit window, not in preview or any other dialog.

Everything went well.

ls .libs

[karasu]

.libs

OK, hidden folder. Now it's working!
Actually I had an error message telling me nnedi3 is already loaded. So I don't need to declare the path. I guess it was effectively installed from the PPA.

Thanks for your help!

Ubuntu 16.04, VapourSynth Editor r8, ctrl-s does nothing when my cursor is in the editor. maybe it's a unity/QT5 thing?

[karasu]

Is "Save" action hotkey set to Ctrl+S in your settings?

yes, in the file menu, Ctrl-S is written after "Save file"

Ctrl-S works fine in other applications.

[karasu]

It's the same with Avidemux (QT5). And nothing in the console when I hit ctrl-s. So I guess it's a Ubuntu/Unity/Qt5 thing.
