iOS 5 supports fast forward and reverse playback. However, you don't need to produce special purpose content to support fast forward and reverse playback. All you need to do is specify where the I-frames are. I-frames, or intra-coded frames, are encoded video frames whose encoding is independent of any other frame. To specify where the I-frames are, iOS 5 introduces a new I-frame only playlist.
