HLS typically has a delay of around 30 seconds, roughly comprising three segments, each lasting 10 seconds. We can reduce the delay to about 5 seconds by lowering the segment duration to 2 seconds and starting playback from the last segment, achieving a stable delay.

Of course, this requires setting the OBS's GOP to 1 second, and the profile to baseline, preset to fast, and tune to zerolatency. Additionally, updating a few configurations in the hls.js player is necessary, such as setting it to start playback from the last segment, setting the maximum buffer, and initiating accelerated playback to reduce latency.
