Do I need to use FFmpeg 32-bit (x86) version?

I am using MeGUI x86 version 6.6.6.6 (20251116) on Windows 11 Pro. I am trying to update the internal FFmpeg version to 8.0, but MeGUI fails to utilize it.

The problem is hen I point the executable path to FFmpeg 8.0, I get an error saying

"toolsffmpegffmpeg.exe" -loglevel level+error -I megui

However, when I revert back to FFmpeg 5.0, everything works perfectly.

What I have tried:

  • I verified that the FFmpeg 8.0 build is also 32-bit (x86) to match MeGUI..
  • I tried running MeGUI as an Administrator.
  • I checked the logs, but they only show toolsffmpegffmpeg.exe" -loglevel level+error -i megui.

Is there a specific compatibility issue with MeGUI x86 and FFmpeg 8.0, or do I need to update a specific script/plugin to make it work?
