I-Frame Playlist

šŸš§

Note

This feature available only for advanced_hls, fmp4_hls, and advanced_fmp4 output formats.

iOS 5 now supports Fast Forward and Reverse Playback. However, you donā€™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 frames, are encoded video frames whose encoding does not depend on any other frame. To specify where the I-Frames are, iOS 5 introduces a new I-Frame only playlist. Read more at Apple dev technote.

The Encoding.com API exposes this format of output by having the user request set the add_iframe_stream parameter to yes in a job request's stream section.
