presentationWindowInUnits

The relative to end sliding window. Applies to Live Streaming only. Use presentation_window_in_units to apply a sliding window of fragments to include in a playlist. The unit is defined by unit_timescale_in_miliseconds. For example, set presentation_window_in_units to 120 to apply a two-minute sliding window. Media within 2 minutes of the live edge will be included in the playlist. If a fragment straddles the boundary, the entire fragment will be included in the playlist. The minimum presentation window duration is 60 seconds.
