Video display with huge delay

[apofis1969]

I am using right now version 1.0.6 for live video streaming in my app between 2 devices.
Starting with 1.0.8 there is a problem which I do not know how to fix:

I get on the server the messages:
org.red5.server.adapter.ApplicationAdapter - W3C x-category:stream x-event:play c-ip:95.90.20.44 x-sname:147885d9-9c0f-4602-ab54-3fa988560528 x-name:38468233_95org.red5.server.stream.ClientBroadcastStream - Stream start: 38468233_95
Jun 09 07:26:04 ip-172-26-13-79 red5.sh[451]: [INFO] [RTMPConnectionExecutor-2] org.red5.server.adapter.ApplicationAdapter - W3C x-category:stream x-event:publish c-ip:95.90.20.44 x-sname:63d44a47-81e7-42d7-875d-3be00267abe9 x-name:38468233_95

All this is fine and correct.

But it takes more than 10 seconds until the video is displayed on the device. This delay does not exist with 1.0.6

How can I fix this? Where can I adapt the settings to reduce the delay.

The messages I get in my app are:

NetStream.Publish.Reset, NetStream.Publish.Start - these two are fast
But then it takes 10 seconds and more until I get the message "NetStream.Video.DimensionChange"

This problem started with the integration of the org.red5.server.tomcat.WarDeployer - Deploy wars with app start

The app is developed with Adobe Air.

Thanks for your help in advance.
