Encoder produces segments. Playlist grows. Player fetches behind live edge.
What you're seeing
HLS: media stream split into N-second segments (typically 4-6s). Playlist (.m3u8) lists segments. Player downloads from start (or live edge for live streams). Latency ≈ 2-3 × segment duration.
LL-HLS: partial segments + delivery directives → 2-3 second latency vs traditional 30s.
★ KEY TAKEAWAY
HLS: encoder produces N-second segments; player downloads behind the live edge. Latency ~ 2-3× segment duration.
▶ WHAT TO TRY
- Click Start stream — watch segments fill in.
- Adjust Segment dur — shorter = lower latency but more overhead.
