How to install avideumx external filters ?

I've been trying to install an external filter to avidemux without much luck, including groping thru the avidemux wiki/docs and avisynth docs, and haven't been able to find some very basic information.

Before I forget, please don't recommend the avisynth wiki page because it doesn't address this question.

Questions:
- Are the filter files always DLLs?
- Are these windows DLLs, and do they work as filters in Linux?
- If the Linux filters are NOT .dll files, what are they (extention)?
- If anyone has added external filters to either windows or linux version, how did you do it and what kind of file was it?

I have two versions of avidemux:

- Linux version 2.5.2: w/option to tell it where the external filters are.

- Windows version 2.5.6 working fine under wine: NO option to tell where external filters are.

I downloaded the Hdragc-1.8.7.zip filter for a test. The zip files contains AGC.dll, a license.txt file and a hdragc-help.htm file which doesn't tell how to install the filter. The DL page also doesn't tell how to install it or whether it's for windows or linux or both.

But I gather that the file "AGC.dll" is the filter!

Here's what I've tried:

1- Linux: extract AGC.dll somewhere and tell Linux version where it is.
It doesn't show up.

2- Windows/wine: since I can't tell it where the filter is, I put AGC.dll in the ~/.wine/drive_c/Programs/Avidemux/plugins/videoFilter directory with other video filters (dlls)
It doesn't show up.

????

Thanks!

What is your wine version?
Does Avidemux run under wine without any errors?

$ wine --version = wine-1.4-rc6

I get the below errors from any sound app w/wine, but they all work fine including avidemux:

Code:

$ wine --version = wine-1.4

I get the below errors - Avidemux does not start and crashes:
