We keep live playback at a consistent distance from the live edge using small playback rate adjustments, with a target range based on recommendedTimeOffsetFromLive. Since the live edge is not exposed by AVPlayer, we currently fall back to seekableTimeRanges.end as our best approximation.

  1. What should be treated as the live edge, and how should the current live latency be measured?
  2. Is rate adjustment the appropriate way to hold a target latency? While playing above 1.0x, the playhead can reach the seekable end, at which point AVPlayerItemDidPlayToEndTime fires and halts the live stream. How can we guard against ?
  3. Does any of this differ between regular HLS and LL-HLS?

A clear statement of the intended contract here would resolve a lot of uncertainty.

Thanks in advance.
