Quicktime Player RTSP multicast

Hi,

I'm having a problem with RTSP session for a multicast stream with Quicktime Player.

This works fine in VLC but in Quicktime Player (v7.6.9) the Setup request always requests a transport type of unicast and I'm unable to view the multicast stream.

C->S (describe request)

When I try this with VLC it responds with a setup request for multicast transport. VLC recognises that the connection information contains

a multicast address and changes the transport type to multicast. The VLC Describe response is the same except it doesn't contain the 'x-qt-text' attributes.

SETUP rtsp://192.168.202.55/videocontrol RTSP/1.0

CSeq: 4

User-Agent: LibVLC/2.0.1 (LIVE555 Streaming Media v2011.12.23)

Transport: RTP/AVP;multicast;client_port=1708-1709

I've tried adjusting parameters in the Describe response but I can't get it working with Quicktime Player there must be something I've missed.

I'd greatly appreciate any help

Regards,

Steve
