I have done some changes on my Origin Server settings for reducing delay to Apple HLS [cupertino] . Do I need to enable the same settings on my Edge Servers ?.

cupertinoChunkDurationTarget

2000

Integer

cupertinoMaxChunkCount

10

Integer

cupertinoPlaylistChunkCount

3

Integer

cupertinoRepeaterChunkCount

3

Integer

There is acceptable delay on my Origin server after enable the above settings , whereas my edge server has more delay. So , Do I need to enable the same settings in my Edge server also ?.

Hello there.

In a live stream repeater (origin/edge) configuration, packetizers are set with repeater values on each Wowza edge server. e.x:

**cupertinostreamingrepeater**

Please review this guide for more information:

[Configuring HTTP packetizers](https://www.wowza.com/docs/how-to-configure-a-live-stream-repeater#configurePacketizers)

Regards,

Salvadore

Hi,

Yes it’s recommended that you edit the cupertinoChunkDurationTarget on your edge(s) to match the cupertinoChunkDurationTarget on the origin server where the stream is repeating from.

> cupertinoChunkDurationTarget - Sets the duration of each chunk in milliseconds. If you’re using Origin/Edge configuration this will need to be set on the Origin and Edges with matching values.

> This is outlined in the article [How to configure Apple HLS packetization (cupertinostreaming)](https://www.wowza.com/docs/how-to-configure-apple-hls-packetization-cupertinostreaming%28cupertinostreaming%29#livepropref).

You want to configure on the origin and repeat on the edge.

@salvadore , Sorry for the delayed response.

Thanks for your comment.

Do I need to set the same property values in Edge Server what I set in Origin like cupertinoChunkDurationTarget and so on ? . Or its no needed to enable the same property in Edge servers
