lets take a step back here

The problem is not SDL, the problem is any GUI on the MAC am i correct ?

so the idea is that we cannot access any GUI in any code from anything in
libavformat and probably all other libs, ever

no debug with graphical output
no vissualizuation of anything
no devices
no libs that expose anything that would need a GUI for configuration

thx
