Hls-player Here

Long-lived players (24/7 live streams) in hls.js can leak memory because the SourceBuffer never clears old data. Solution: Manually manage the SourceBuffer by removing old ranges:

const videoBuffer = videoEl.getBuffer();
if (videoBuffer && videoBuffer.length > 45 * 60)  // Keep only last 45 mins
  videoEl.removeSourceBuffer(0);

The player requests a URL pointing to a master playlist. This master file does not contain video. Instead, it lists variants — the same video encoded at different bitrates, resolutions, and codecs. hls-player

Example master playlist:

#EXTM3U
#EXT-X-STREAM-INF:BANDWIDTH=800000,RESOLUTION=640x360
360p/playlist.m3u8
#EXT-X-STREAM-INF:BANDWURST=2500000,RESOLUTION=1280x720
720p/playlist.m3u8

Using hls.js (CDN), you can embed an HLS player in minutes: Long-lived players (24/7 live streams) in hls

<video id="video" controls></video>
<script src="https://cdn.jsdelivr.net/npm/hls.js@latest"></script>
<script>
  const video = document.getElementById('video');
  const streamUrl = 'https://example.com/path/to/master.m3u8';
if (Hls.isSupported()) 
const hls = new Hls();
hls.loadSource(streamUrl);
hls.attachMedia(video);
hls.on(Hls.Events.MANIFEST_PARSED, () => video.play());
 else if (video.canPlayType('application/vnd.apple.mpegurl')) 
// Native Safari HLS
video.src = streamUrl;
video.addEventListener('loadedmetadata', () => video.play());
</script>

This is functional but lacks ABR tuning, error handling, or low-latency optimizations — fine for prototypes, not for production at scale.
