I am live streaming to Wowza server. I have a H.264/AAC encoder. I am getting messages similar to the one below.

JNI:AudioDecoderAAC.decodeFrame[_defaultVHost_:live/_definst_/jhwa]: Timecode queue: 102

I would like to understand what it means. I suspect there is a problem with my AAC encoder. I would like to understand what it is that Media Server does not like in my AAC frames. I am not switching encoders on the fly as was the case in some posts in the past. I also see that audio and video get out-of-sync after few minutes. Can it be related to this message?

Thank you very much,

Are you getting any other accompanying error messages in the logs?

You can follow this guide to create a recording of the stream for debug purposes and send to support@wowza.com:

As a followup this was resolved by moving the last patch for 3.6.4, patch2.
