Hello,
i am new the wowza and got simple Icecast MP3 Restreaming to work quite easily 
I can listen to different icecast streams now via Flash Player, VLC (rtsp) and iOS.
But i can’t get the transcoding to work ;(
My Application.xml based on the wowza tutorials and suggestions:

The system is an Debian (still Lenny) 64bit running a Wowza 3.1.2 with java 1.6.0_26
In the access.log the following lines are listed:
JNI:TranscoderSession.audioDecoderCreate[_defaultVHost_:live/_definst_/***.stream]: Create audio decoder: MP3: default
transcoder INFO 200 ***.stream {codec:MP3, objectType:MPEG1LAYER3, sampleRate:44100, channels:2}
JNI:TranscoderSession.audioEncoderAdd[_defaultVHost_:live/_definst_/***.stream:aac]: Create audio encoder: AAC: default
JNI:AudioEncoderAAC.initialize[_defaultVHost_:live/_definst_/***.stream:aac]: channels:2 sampleRate:44100 bitRate:48000
Listening to .stream works well, but listening to mp4:.stream_aac plays no music at all and from time to time some rubbish (like extreme fast forwarding) can be heard.
What do i miss? Any ideas?
