No I added that one due to knowing that you on packman did not want to 
build it with full fdk-aac in the past.
Hence I did it this way, so that it would be built with the altered 
sources we have in main obs, and not the full fdk-aac.

Take a look at https://pmbs.links2linux.org/project/prjconf/Essentials 
- I suspect this could be the reason for the hickup

# have choice for pkgconfig(fdk-aac): fdk-aac-devel libfdk-aac-devel
Prefer: -libfdk-aac-devel

This could however all have been avoided if we switched packman to only 
build the extra codecs in orig addon.
Those are the only plugins that differ, and what people need.

There is no reason whatsoever for rebuilding and providing the "normal" 
plugins.

See examples of how this could be done in

https://pmbs.links2linux.org/package/show/home:zaitor/gstreamer-plugins-bad-codecs
and
https://pmbs.links2linux.org/package/show/home:zaitor/gstreamer-plugins-ugly-codecs

That way there would be no "vendor switching" when installing the extra 
codecs.
