ffmpeg.exe for Linux?

[tboooe]

Hi guys, I am trying out Linux (Lubuntu) and have successfully installed Minimserver. I've been using Minimserver on Windows machines for a while now with ffmpeg and the following settings in stream.options property:

convOut=-af aresample=resampler=soxr:precision=28

I downloaded the 32bit version of ffmpeg from this site:
http://johnvansickle.com/ffmpeg/

I placed the file ffmpeg into the folder minimserver/opt/bin

The full path is
/home/tboooe/Documents/Minimserver/minimserver/opt/bin/ffmpeg

However, in the properties screen I get the error "Converter not installed"

Any ideas?
