Hello,

I try to synchronize multiple ip camera stream on the server :

I have several IP camera which capture live events. a web video mixer allows to switch between streams with this wowza module : [https://www.wowza.com/docs/how-to-switch-streams-using-stream-class-streams](https://www.wowza.com/docs/how-to-switch-streams-using-stream-class-streams). By adding the property “setStartLiveOnPreviousKeyFrame” it works very well.

Except that there is a slight shift between streams , which is annoying when you switch between camera A and camera B and camera B is 2 seconds behind the A.

Is there a way to synchronize all streams on the wowza server side ? with rtsp timestamp ?

Thanks,
