> You have to flush the encoder (or disable B-frames).

To ensure I'm flushing the encoder I call avcodec_encode_video2 at the very end 
where the 3rd argument - the frame - is set to NULL.

My guess is that to disable B-frames I need to set

AVCodecContext *c;

c = ...
c->max_b_frames = 0;

When I do both of the above, I end up with a much larger file (around 2MB as 
opposed to 200K) - which I believe is a good thing for my purposes. However, I 
put 36 images on the video. If I play the video with Windows Media it only 
shows 18 of them; if I play it with VLC Media Player it only shows the first.

Interestingly enough, if I add each frame 3 times, then Windows Media Player 
goes further than before (with a 10MB file!) - but still doesn't display the 
last image.

I'm hoping this behavior is a good clue to what I'm doing incorrectly. Any help 
is truly appreciated.

Thanks for the help.
