The reference software (C-code) is not developed for a certain Windows OS at 
all. It was developed mainly under Unix systems, and is basically intended to 
run with gcc. Some contributors provided some *.ds[pw] files, but they might be 
outdated.

I wonder how libraries found their way into the distribution. You are strongly 
encouraged not to use these libraries but to build them on your own. The 
libisomp4 / libisomedia should be available as source code as part of the 
Systems reference software. The libtsp source code is available here: 
ftp://ftp.tsp.ece.mcgill.ca/pub/AFsp.

This problem should now be solved.

I guess this is not necessary.
