Common HLS Stream Problems
Symptoms and causes: "Loading" but never plays = slow server; plays then stops = missing segments; constant buffering = bandwidth too low; black screen with audio = codec not supported.
Server-Side Issues
Check: correct Content-Type header, TS segments accessible, CORS headers configured, byte-range requests supported if used.
Latency and Live Stream Issues
Live HLS has 6-30s inherent latency. LL-HLS can reduce to 2-5s. Check if the playlist updates correctly with new segments.
