Did you actually test it? Most machines should be fast enough decoding mpeg2/4 video frames that monitor refresh rate is more likely to be the actual limiting factor on number of frames you can see. I think there's no way to make the FFmpeg decoder produce incorrect frames like that, so if you actually want to see them then you'll have to use libmpeg2.
