Bug#203211: RFP: avidemux -- A small editing software for avi (especially DivX)

[Fabian Greffrath]

Hi all,

I have checked the rpmfusion package for avidemux and they have 
patched it to use the system libraries for libass, liba52, llibmad and 
libtwolame at least. Furthermore, the package has "BuildRequires: 
ffmpeg-devel" but I could not found a patch to force it to use the 
system ffmpeg libraries.

I have put Richard Shaw, the maintainer of this package in rpmfusion 
into CC. Richard, can you tell us more about avidemux' usage of the 
ffmpeg libraries in your package?

Best Regards,
Fabian

PS: Sorry for top-posting, but the following text is a rather decent 
summary of our previous discussion...
