Thank you very much all who reply on this subject.

I think probably I should let the encoding untouched.

Btw, what is this AVCodecContext.real_pict_num? Is this the real input picture number of the just returned encoded data from avcodec_encode_video2()?

I cannot try this, my machine crashed. I'm currently reinstalling the OS (FreeBSD 9), it may take few days as compiling from source.
