HLS chunk size issue

We are seeing large EXT-X-TARGETDURATION value in our m3u8 list. The value “EXT-X-TARGETDURATION:10” is not matching our settings in cupertinoChunkDurationTarget of 1000. Any idea why this is happening, and suggestions on fixing this?

We are using wowza 4.4.1

Hello!

Thanks for contacting Wowza Forums!

What are you keyframes set to on the incoming stream? Here is the article on chunk duration. Scroll down to the Property Details section and read on how keyframes and chunk duration need to line up to get the correct output: ARTICLE

Here is another forum post that has some information on this: HERE
