I can not decode MP4A-LATM stream with using UMC::AACDecode.

I use Live555 library for receiving RTSP streams. A lot of RTSP streams contains audio stream with SDP strings:
m=audio 0 RTP/AVP 96
a=rtpmap:96 MP4A-LATM/48000/2
a=fmtp:96 profile-level-id=15;object=2;cpresent=0;config=400023203FC0
a=control:trackID=1

From Live555 I recieve full packet with header LATM (2 bytes), I can not tune UMC::AACDecode for decoding these packets, decoder always returns UMC_ERR_UNSUPPORTED.

In mailing list of Live555 I found http://lists.live555.com/pipermail/live-devel/2006-May/004356.html
I attempted give to decoder packets without LATM header, but this too does not work.
What I must do for launch UMC::AACDecode with this type stream ?

While I do not want to get in the way of any other replies on this topic, I'd just like to post a friendly reminder that the UMC sample is now legacy and outside of our support scope.  For more info please see Previous external samples package now legacy above.
