Short answer

A master playlist points to one or more variant streams, usually with different bandwidth, resolution or codec information. The media playlist then lists the actual segments for one variant.

What to check

  • Confirm that the stream is public or authorized for testing.
  • Use the Checker to separate access problems from playlist structure.
  • Do not treat a diagnostic result as permission to copy, bypass or redistribute media.

Next step

If the answer points to access, fix the origin policy or authorization first. If access works, continue with playback, segment and codec checks.
