Hi Falconetti,

Great to hear it's working for you now.

On rereading the FFmpeg documentation (Section 6.3.1), most of this 
seems to be in it -- with the exception of copying the commands from 
vcvars32.bat into autoexec.bat (so link.exe is on the path). If desired, 
I'll submit a patch to the documentation that includes this information.

The second option is definitely preferred.

Again, the second option (putting the preprocessor definition in Project 
/ Settings) is definitely preferred.

Thanks for the feedback -- can you give me some detailed information on 
where to set the various options in "Project / Settings"? Especially: 
Where to set the include and library path, and where to add the 
additional preprocessor definitions (does something along the lines of 
"-DEMULATE_INTTYPES" have to be added somewhere)? I'd like to add a 
short note about this to the documentation.

Also, do I understand correctly that both "CONFIG_WIN32" and 
"EMULATE_INTTYPES" have to be added to common.h, or is it just the latter?

Martin
