I want to add something to my last mail Stephan. Did you decode frames from 
your h.264-files? I could decode a frame but my program crashes now, if I 
want to transform it to a rgb-file with the help of swscale.

If you could decode your frames, could you paste the interessting code 
snippets here? Thank you very much.

regards,
Sven

PS: With MPEG2 and swscale it works.
