We're trying a new h.264 IP camera from Bosch, the Dinion NBN-921-P. Since we need to have a bunch of users connect to both the camera (hyper low-latency) and Wowza we want to multicast the traffic from the camera. Awesome. Set up multicast and have it working great in VLC. No matter how many people connect the CPU stays around 20%.
Using the same URI: rtsp://IP/?multicast=1 in Wowza yields a very high CPU marker. Opening Wireshark shows that the multicast stream is not flowing to Wowza but instead it is Unicast.
Was wondering if anyone knew how to force this to be multicast. I don't have an SDP file from the camera. When I do multicast the camera and pcap it, then set an expression of 'sdp' in Wireshark I don't get any results so I'm not sure how to manually build the file either.
Anyone have any clever options? Any way to force Wowza to try and grab the multicast? Any way to easily get the SDP information downloaded from the camera either via a pcap or some other clever method?
