Topic: Can't get SVP to run (mpv/vapoursynth issue?)

Hi everyone,
so, I have a problem: I have already installed Vapoursynth and Python and zimg and all that, but SVP tells me it doesn't work (see attached picture)
Now though it's not my first time using Linux, I can't get this to work, and the internet doesn't tell me anything. If that helps:  vspipe -v is (mostly) happy. But mpv doesn't even list VS in the vf=help section.
Log:

If you need any more information, feel free to ask me, I'd be glad about any help.

I can't reply?
So here is a reply as an edit:
Thanks Chainik,
so I did rebuild it (and sudo installed it), but SVPManager still tells me mpv didn't find vapoursynth. How do I make sure mpv correctly discovered and installed VS? I'm kind of lost here...

Re: Can't get SVP to run (mpv/vapoursynth issue?)

you have to _build_ mpv after installing all of these stuff

check the mpv's configure output while building...

Thank you very much smile
So I rebuild it again and took a copy of the log. I don't want to cause too much trouble, but just in case there is something else I might have overlooked, I attached the whole log. But I believe only the last lines are interesting as in line 4468 and 4638 it says "compiling [...] vf_vapoursynth.c" - which leads me to believe that it did compile and, after ./install, install it. - ?

Re: Can't get SVP to run (mpv/vapoursynth issue?)

and installed where? are you sure /usr/bin/mpv is _this_ version you just built?

Re: Can't get SVP to run (mpv/vapoursynth issue?)

Ah no it's installed at /usr/local/bin/mpv
Install log for completeness: https://pastebin.com/irHfaQeb
Do I need to change that?

Ah thanks, that did the trick! Now it's working. I'm super excited how this will turn out! smile
Feeling rather stupid now...

if you're actually running /usr/bin/mpv - what do you think?

mpv's path is in All settings -> main.setup.player

Re: Can't get SVP to run (mpv/vapoursynth issue?)

Okay so hi again, I now got another issue: 4k is not working. 1080p works and I'm very happy with it, it's really smooth! 1080p works with both encoders (264+265), but 2160p always fails:

No matter whether I take the h.264 or h.265 encoder, it would fire up, count up a few numbers, show 0.1fps and it fails directly after that. Does SVP then even support 4K? I tested the same file, encoded in HandBrake, same settings (RF same, not the bitrate, that'd pointless, and h.265), just downscaled for the 1080p version.

Re: Can't get SVP to run (mpv/vapoursynth issue?)

this probably means out of memory

Re: Can't get SVP to run (mpv/vapoursynth issue?)

Ah yes, didn't know mpv would be using more than 4.5Gigs. You're genius, thanks! It's working now smile
