Did it but with that it's even worse. So it's not the case. I'm worriyng
however about the "if needed" part.

The general idea is that decoding algorythm is broken (see the example usages
of ffmpeg libavcodec). It decodes packets but does nothing to frames.

Also why K3bFFMpegFile::fillOutputBuffer() method is being called recursively?
It's better to use while loop here.

Also it would be reasonable to get rid of all the legacy ffmpeg support code.
The most part of it exists since KDE3 times. No point in having it now.
