Wowza Media Server 3 Perpetual Edition 3.6.2 build5334
We’ve noticed when cupertinoRelativePlaylistPlaylists is set to false Wowza seems to generate bad chunklist URLs and the player requests the same chunks under multiple session IDs. This causes the stream to jump back and repeat every once in a while.
Here’s an example of the URL that is generated in the [application]/playlist.m3u8

Whereas when the parameter is set to ‘true’ everything works as expected with the session ID remaining constant:
