- Q:What is HLS?
- A:HLS (HTTP Live Streaming) is a streaming protocol. Streams are served as playlists (.m3u8) that reference video segments. Most browsers and players support HLS. This player loads your M3U8 URL and plays it in the browser.
- Q:Why does my stream not play here?
- A:Common causes: the URL is not HLS, the server blocks requests from this site (CORS), or the stream requires authentication. Use Stream Lab to verify the URL and the Why Won't It Play? checklist for steps.
