I’m trying to figure out what the **cupertinoMaxChunkCount** setting does. I’ve searched on the forums and looked in the documentation but I can’t find a definitive answer.

Here are my configuration settings for the live application:

```auto
<LiveStreamPacketizer>
	<Properties>
                <Property>
                	<Name>cupertinoPlaylistChunkCount</Name>
                	<Value>5</Value>
                	<Type>Integer</Type>
                </Property>
                <Property>
                	<Name>cupertinoMaxChunkCount</Name>
                	<Value>8</Value>
                	<Type>Integer</Type>
                </Property>
	</Properties>
</LiveStreamPacketizer>

```

I came across this [page](https://www.wowza.com/docs/how-to-configure-apple-hls-packetization-cupertinostreaming%28cupertinostreaming%29) on configuring HTTP Live streaming and it states the following:

> The maximum number of chunks stored in the available chunk list is controlled by the cupertinoMaxChunkCount setting.

This doesn’t appear to be the case from my experiments. When I request the playlist for the live stream there’s never any more than 5 entries in it, which corresponds to the value of the **cupertinoPlaylistChunkCount** setting. (I assume ‘available chunk list’ is referring to the playlist.)

What is the **cupertinoMaxChunkCount** setting used for?

I’m using Wowza 4.1.

Thanks

Hello there,

**cupertinoMaxChunkCount** is the total number of chunks that are maintained. So as the stream moves a bit further off of live, the player will start to request segments from further in the past. Having a larger list of chunks in reserve will insure this does not lead to a missing chunk error.

Kind regards,
