Topic: [Solved] PotPlayer freezes and crashs when using Avisynth Filter

First, SVP works fine with ffdshow raw, but I want it to work with HDR videos, so I am switching to Avisynth Filter.

I have followed this page to installed and enabled Avisynth Filter:
https://www.svp-team.com/wiki/Avisynth_Filter_(AVSF)

However, when I start SVP with Avisynth Filter enabled, PotPlayer will freeze in 2 seconds after start playing a video (no mater resolution or HDR), and some video it turns into green screen, while I can still hear the audio goes. Then the player just crash if I try to click anything.

Strangely, even I disable the SVP frame rate conversion, the player still freezes. I have to completely exit SVP from background to make Avisynth Filter working on PotPlayer.
I tried to restore settings of SVP, but that didn't help.
I tried to use other decoder and disable madvr, but the problem still persists.

Any idea where goes wrong?

PotPlayer version: 220302
SVP version: 4.5.0.213
Decoder: LAV+madvr
OS:Windows 10 21H2
GPU: RTX 2080ti

I can't find any useful information in the log file either, I will enclose it as well.

SVP only works with specific version of filters:
AviSynth Filter: 1.3.1 (as bundled with SVP)
AviSynth+ : 3.7.0
Switching to versions above solved the problem.

Yes it is 1.4.0, can you find anything wrong in the log file?

I am giving you a screen shot at the LAV decoder setting page.

Re: [Solved] PotPlayer freezes and crashs when using Avisynth Filter

The problem is actually in Avisynth 3.7.1+.
3.7.0 works good.

Dunno if the problem is in AVS itself or Avisynth Filter.
