[Libav-user] Frames are not visually lining up between my code and ffmpeg.exe

Interesting. There was a difference of 30 between the frames that
ffmpeg.exe output and the result of ->nb_frames.

Sure enough, ffmpeg.exe with -vsync 0 output 480 frames instead of 510. So
now how do I get my code's output to match ffmpeg.exe's output? (and
hopefully skip frames in the process)
