I tried this version and the problem changed to can't locate entry of 
av_alloc_format_context at avformat-52.dll. Seems the main problem is in this 
file? I noticed in some of the includes, the include path has an additional 
directory name(e.g. #include "libavutil/avconfig.h" in a include already in 
the libavutil directory), which makes gcc fail but ok in VC.
Is the entry error a incompatible issue with VC? If so, if i want to build it 
in gcc, how to solve the directory problem, can i simply remove the directory 
names in includes?
