missing last frame may be related to this:
Also, just a guess but 18 is half of 36. Is it possible you need to set some interlacing option ?

I also noticed that the call to avcodec_encode_video2 returns got_packet=0 about half the time. I suspect this is related. But other than setting max_b_frames to zero I'm not sure what else I need to do to recover all my frames all the time.
As long as I remember I solved a similar problem after providing the last frame of the sequence by calling avcodec_encode_video2 with frame parameter being NULL in a loop while got_packet returns true.
