We just switched some servers from 4.0.3 to 4.1.0 and our rtp-live-lowlatency application stopped working. The problem is that the Wowza server stopped including the media attributes that included necessary SDP info in the RTSP response to DESCRIBE.

If the Application.xml uses RTP "interleaved" to access the streams from the encoders it's works. But if the Application.xml uses RTP "udp" to access the streams that are multicast then it breaks. When the client player receives the response to the DESCRIBE the lines that contain the media attributes are missing.

I can take the same Application.xml from the 4.0.3 server to the 4.1.0 and it doesn't work under 4.1.0.
