HLS Player (hls.js)

Play and debug HLS (.m3u8) streams in the browser with the latest hls.js.

Play and debug HLS (.m3u8) streams directly in Chrome with hls.js — and switch between hls.js versions to compare how a stream behaves. Built for developers and QA teams who need to check what a web player actually does with a stream: whether the duration is right, how discontinuities are handled, what gets buffered, and which errors come up. FEATURES • Open any .m3u8 URL in the player: paste it in the popup, navigate to it directly, or right-click a link and choose "Play in HLS Player" • Switch hls.js versions in one click. Seven versions are bundled, from 1.4.14 up to the latest 1.7.4, so you can check whether an issue is in the stream or in a particular player version • Live stats: playlist duration vs media duration (with a warning when they differ), fragment and discontinuity counts, position and program date-time, buffered ranges, quality level, bandwidth estimate, dropped frames, and errors • Quality level and audio track selection • Event log with optional per-fragment details (sequence number, discontinuity, start time and duration) • "Copy debug info" puts the stats and recent events on your clipboard for bug reports • Optional hls.js debug logging to the DevTools console • Light and dark mode HOW TO USE 1. Click the extension icon and paste an .m3u8 URL, or open an .m3u8 link in a tab. 2. Pick an hls.js version from the menu at the top of the player. 3. Watch the Stats panel and Events log while you play and seek. Automatic opening of .m3u8 links can be turned off in the popup. PRIVACY This extension does not collect, store or send any personal data. Streams are fetched directly from the URLs you choose to play. Settings such as your preferred hls.js version are stored locally in your browser. CREDITS hls.js is open-source software by the video-dev community, licensed under the Apache License 2.0.
