Error ....... was not created

[fah]

Okey i did a fresh install of Arch. Now the AUR version works but without vapoursynth (it doesn't let me choose any synth). The binary version with the tools from your website looks like it works (i haven't tried the m2ts file yet but the programs boots and vapoursynth seems available). The binary version without tools doesn't launch (same errors as before). Both versions downloaded from the websites throw the same errors in the output but one manages to launch while the other crashes.
Regarding the AUR version, I had vapoursynth already installed because it's a dependency of both mpv and ffmpeg. The version is R70-2 (it's flagged as outdated). Can i provide something to better understand why vapoursynth is not detected by Hybrid ?

Can i provide something to better understand why vapoursynth is not detected by Hybrid ?

If you start Hybrid through the command line, it should report where it tries to find Vapoursynth (vsViewer and other tools too).
If your Vapoursynth or the Vapoursynth scripts Hybrid uses (see: https://github.com/Selur/VapoursynthScriptsInHybrid/) are not hinted through a misc.ini and can't be detected Vapoursynth will not be supported. ( see: [INFO] *hidden* Hybrid options,...)

It wasn't detecting the script folder, now it successfully enable vapoursynth but the app can't launch  

I surrender, thank you very much for your help. I will try again in the future

i'm kidding i will just try to use the full-version from the website ahaaha.
When trying the vspreview you talked about at the beginning i get this

 Do you have any idea what it can be?

[fah]

Is it possible that the reason is it can't find this Lsmas (or lsmash?). Any way i can set this plugin path?

Vapoursynth&plugins must be provided by the user.
I wrote scripts to build them, see: https://github.com/Selur/hybrid-vapoursynth-addon (always happy when someone offers patches or help with the scripts).
According to

Failed to load /usr/lib/vapoursynth/libvslsmashsource.so. Error given: /usr/lib/libgobject-2.0.so.0: undefined symbol: g_pointer_bit_unlock_and_set

Hybrid does find libvslsmashsource.so but can't use it since libgobject is missing.
try whether:

sudo apt-get install libglib2.0-dev

or

sudo apt-get install libglib2.0-0

helps.
