Live streaming with no audio is not playable on iPhone.

Is this a iPhone is limitation, I am sure there no issues with Wowza.

If limitation with iPhone, is there any work around for this?

I am not noticing the behavior you are referring to, live stream works fine with no audio on iPhone for me.

Does your stream not include audio? Or is the audio not being delivered to the device?

What is the source of the stream?

And what are the details of the stream?

- Source stream does not have audio.

- This is a RTSP re-streaming.

First off, you should change the profile to “baseline 3.1” you have a profile of “baseline 4”. Also, the frame size is very large, I suggest reducing this by half and see if that helps.

It looks like you have a keyframe every second, so you can configure cupertinostreamingpackeization to better match the keyframe interval with this guide:

[How to configure Apple HTTP Live Streaming packetization (cupertinostreaming)](https://www.wowza.com/docs/how-to-configure-apple-hls-packetization-cupertinostreaming%28cupertinostreaming%29)

Set the cupertinoChunkDurationTarget to 1000:

```auto
<Property>
	<Name>cupertinoChunkDurationTarget</Name>
	<Value>1000</Value>
	<Type>Integer</Type>
</Property>

```
