From c39c565630f3a09b76da7a3f0a4d7a37945e0325 Mon Sep 17 00:00:00 2001 From: Adam Soltys Date: Mon, 19 Oct 2026 00:44:32 -0700 Subject: Watching a stream: a stream that's on plays through hls.js, held near the live edge (1.5 s back, up to 1.1× when it drifts past 5 s) — Chrome's own HLS player starts three segments back, never catches up, and fails outright (DEMUXER_ERROR_COULD_NOT_PARSE) if a page changes its speed. With the live server's 1 s segments a viewer is 3.5 s behind the broadcaster, from 8.6 s (go-live-test LATENCY=1 measures it: the broadcaster's camera is a clock in black and white blocks, read off the viewer's frame). Recordings, and streams where hls.js can't run (iOS), stay on the browser's player.
