About this tool
The HLS Packaging tool converts your video into an HTTP Live Streaming (HLS) package — a .m3u8 playlist file plus a set of short video segments. HLS is the standard format for adaptive streaming on the web, iOS, and most smart TVs.
Guide & tips
- Segment duration of 6 seconds is the HLS spec recommendation and works well for most players. Use 2–4 seconds for low-latency live-like content.
- fMP4 segments (fragmented MP4) are required for MPEG-DASH compatibility and work in all modern browsers. Use MPEG-TS only if you need compatibility with older HLS players.
- The GOP size should equal or be a multiple of your segment duration for clean segment boundaries. A 6-second segment with a 6-second GOP means every segment starts on a keyframe.
- Upload all generated files (the .m3u8 and every .ts or .m4s segment) to the same directory on your CDN or server.
- After packaging, use the Inspector tool to verify the output codec and resolution before deploying.
Frequently asked questions
HTTP Live Streaming (HLS) is Apple's adaptive streaming protocol. It splits video into small segments and serves them via a playlist file. Browsers and native players can switch between quality levels automatically based on available bandwidth. Use HLS when deploying video on a website or app that needs to handle varying network conditions.
A master .m3u8 playlist and a set of numbered segment files (.ts for MPEG-TS or .m4s for fMP4). All files must be hosted together in the same directory for the player to work.
Yes. Both video.js and hls.js support the .m3u8 playlist format produced by this tool. Point the player src to the .m3u8 file URL on your server.
Yes. The video is re-encoded to H.264 with the segment boundaries aligned to keyframes. This ensures each segment is independently playable, which is a requirement of the HLS spec.
