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.
