FAQ

Q: Why does the video fail to load?
A: The most common cause is missing CORS headers on the video server. Ensure the stream URL is publicly accessible and the server allows cross-origin requests.

Q: What formats are supported?
A: Primarily M3U8 (HLS). For MP4 and other formats, use the Video Preview tool on this site.

Q: What is the difference between live and VOD?
A: A live stream M3U8 does not contain the #EXT-X-ENDLIST tag and shows "--" for duration. A VOD file includes this tag and displays the full duration.
