I just get code from repository and try to compile QTFFmpegWrapper with this 
steps.

qmake config.pro
make

I added 
using namespace ffmpeg;

to the end of ffmpeg.h and it compiled. my system is 

mascix@mascix:~/tmp/qtffmpegwrapper/QTFFmpegWrapper$ cat /etc/issue
Ubuntu 10.04 LTS \n \l

It may be safer to put ffmepg:: in front of the uint8_t.
Windows compiles also require stdint.h and inttypes.h eg from 
http://code.google.com/p/msinttypes/
