I looked at the code. I've found why it outputs a PFrame but i don't understand 
the code well and i prefer some expert see what he can do :-)

When you use a freshly  initialized encoder, then you go through the 
encoder_encode_bframes function to the line 

line 874 :
    inc_frame_num(pEnc);

And here you increase all counters, among then iFrameNum (=1).

And when the encoder must decide what type the frame is :

line 929 :

    if (pEnc->iFrameNum == 0 || pFr...)

So we never satisfy the iFrameNum == 0.

If someone who understands all this bframe queueing code could fix that.

Regards.
