[Live-devel] Bug about demo.aac

The demo.aac is the one in
http://www.live555.com/liveMedia/public/aac/. I just use
live555MediaServer.exe as the server, VLC and openRTSP as the
clients. The samplerate from the SDP description is 22050 hz, but the
audio decoder (faad) in VLC reports the value of 44100hz, that's
strange and something maybe wrong.

Here is the log messages from openRTSP:

Opened URL "rtsp://192.168.20.1:8554/demo.aac", returning a SDP description:
