avformat.h and swscale.h are headers, libavformat and 
libswscale are libraries.

network.h is another header of libavformat but an 
internal one that you should not need to include: 
libavformat contains network functionality that 
you should be able to use without including this 
internal header.

It is a bug that ffserver includes the header, if 
you want to copy the bug, you will either have to 
provide a config.h header for your needs or making 
your project part of the FFmpeg source structure 
(like ffserver.c). Note that the second solution may
mean that you cannot distribute the resulting binary 
under a different license than the LGPL (or GPL).

An alternative would be to send a patch to the 
developer mailing list to make the needed 
functionality public but I suspect this will not be 
easy.
