HLS M3U8 playlist viewer HTTP adaptive streaming

Simple HTTP Adaptive Streaming (HLS) playlist inspector

Inspect the structure and segments of your HLS playlist!

Hello! Here is a simple tool for inspecting the content of HLS .m3u8 playlists. It might be helpful for debugging or when you want to learn how HLS playlists are structurized.

The tool is capable of:

  1. distinguishing between different playlist types (LIVE, EVENT and VOD),
  2. exploring different stream variant playlists,
  3. listing all the segments in the playlist (for the LIVE playlist it keeps track of all the segments it had seen since the last refresh so it also marks old segments as “stale” when they are no longer in the LIVE playlist’s window) as well as showing their #EXT-X-PROGRAM-DATE-TIME,
  4. for the segments being MPEG-TS containers it can also inspect a timestamp of the first the last samples inside the container - to turn it on you either need to click on the segment which interests you or switch the Auto-load PRC toggle.

I hope you will find it just as useful as I did!
