A rough summary translation of 
http://www.ibr.cs.tu-bs.de/theses/brandt/mpeg4transcoder.html?backurl=%2Fusers%2Fbrandt%2Findex.xml :

Because re-encoding (first decoding then encoding) is very cpu intensive and therefor mostly not realtime they try to develop a technique that will give the same result without full decoding. The work is finished and there should be a c/c++ implementation as a programme and as a library.

And then 
http://www.ibr.cs.tu-bs.de/theses/brandt/mdtranscoding.html?backurl=%2Fusers%2Fbrandt%2Findex.xml 
builds on previous work:

It was discovered this adjusting can be done in various domains as time, space and ditail of sharpness. The task is to code a transcoding-module to mpeg-4 that can ajust the video stream in different domains at the same time. This transcoding shouldn't be done sequential but combined to reduce cpu time. It has to be handed in again as a programme and as a module.

There are more details and a chart at http://www.ibr.cs.tu-bs.de/theses/brandt/mdtranscoding/?backurl=%2Fusers%2Fbrandt%2Findex.xml
Sadly there seems to be no English version available.

Can I do any other debugging meanwhile?
