VOD HLS Buffering and cupertinoChunkDurationTarget

I’ve got a 15 second video that has a keyframe interval of 2. I’ve set my cupertinoChunkDurationTarget setting to 6000. The video takes a hot second to load (using Clappr for playback) and when it does, the video gets to the 6 second mark, buffers for a second or two, then loads the rest of the video. How do I stop this buffering from happening?

Bump. Any help?

What you can change @Michael Doble is the ChunkDurationTarget from 6000 seconds to 2000 milliseconds. The player requires at least 3 chunks at 2 seconds each so this this means the lowest you can get it down for initial playback is a total of 6 seconds ( 3 chunks X 2 seconds each).

Try that and see if that helps. Here is the tutorial on how to change all the Cupertino settings:

I’ve adjusted that setting but the problem remains where the video gets to the 2 second mark and then buffers for a second to load the next 2 seconds of the video. Is this player related (Clappr) or is it a setting in Wowza somewhere? It just seems like only 2 seconds of the video loads at a time.

Nevermind. I’ve adjusted some of my encoding settings and it seems to be loading normal now. Thanks.
