However, it works, if I remove the two guess_format calls from QVideoEncoder.cpp

It seems you are using a newer version of ffmpeg than the one against which 
QtFFmpegWrapper was tested. The function 'guess_format' has been renamed 
av_guess_format in recent versions of ffmpeg.

The release 2011-09-21 fixes this problem: it is built against a recent ffmpeg, 
and the wrapper classes were adapted accordingly.

Try again the new wrapper.
