I did so, but it turned out that when compiling with libswscale the 
GRAY8 input i get is not stretched over the whole 8 bit, thus i get the 
usual valuerange of 16..235 for luma. Whereas when i forgo on libswscale 
i get luma stretched over the whole 8 bit range of 0..255. Would be nice 
if i get the same data with both methods (no matter if stretched or 
not), but how to achieve that?
