NullPointerException in PushPublishRTMP

Wowza Streaming Engine
1

Hi,

I am using wowza in a live streaming use case in which incoming RTP over RTSP data is transcoded to RTMP. The RTMP stream is being pushed to an akamai entry point server. I am able to do this succefully. However i see exceptions being generated from within Wowza PushPublishRTMP module. The following is the log generated:

I am able to receive and play the stream on the akamai server without any issue. I see these logs on few occasions and i am not able to reproduce it consistently. Can this cause any problem? Is there any issue with the way we are making API calls to PushPublishRTMP? Some more information below:

Software version: WowzaStreamingEngine - v4.1.2

OS: Ubuntu 12.04 (64 bit)

The wowza streaming engine software is running on amazon ec2 instance

Hello there.

If the stream is working maybe don’t worry about it? You can always open a ticket with support by sending an email to support@wowza.com

Follow this guide when opening a ticket please:

Also, you can enable debugging of push publish (if you have not done so)
