We do send back packets but I think they are mostly empty. Charlie ---

If using udp the rtcp packets will flow over port one greater than video port or one greater than audio port. It is not possible to send your own packets. C ---

Hi Charlie, > You can change the starting port number. It is defined in [install-dir]/conf/Server.xml. The setting is RTP/DatagramStartingPort. I don’t think this is the problem since the port number are determined by the RTSP negotiation. But see if this helps. I already changed the starting port number to 6990 because the server is also running Darwin Streaming Server. I think the problem is the ending port number. If I change the starting port number to 55300 to try and include the ports which this particular Axis cam seems to want to stream its data on, I still get no working stream. Further more: We have several Axis cams “hooked up” to this server and all of them “play nice” regarding the UDP port range (starting at 6990 in our case). Is a firewall and/or router at the location of this cam possibly causing trouble? Regards, Rudo ---

Take a look at :input-slave=dshow://… or a variation of that option. ---

You can do NetStream.setBufferTime(0) But take a look at this post first: [http://community.wowza.com/t/-/588](http://community.wowza.com/t/-/588) Richard ---

With JW player, you can set buffertime with Flashvar “bufferlength”. > &bufferlength=0 Richard ---

Maybe the bitrate of the stream coming from the camera is too high? Richard ---

I am using the M1031-W model, and it works great for me. You should get a model that natively supports h.264, for example: M1011(-W), M1031-W, P3301(-V), Q1755. The biggest problem I had was my router, which needed firmware update. You have to put the camera in the router DMZ, or setup pass-thru for ports tcp 554 and udp 6970-9999. Richard ---

Wowza Pro streams using UDP on ports 6970 - 9999 and TCP port 554. They should be open on your router if you are using it and on your server, or security group for EC2 Richard ---

Charles, People do run Wowza on VPS. You should have at least 1 gig of dedicated RAM. Generally, network bandwidth is the limiting factor, but I doubt you will have a problem with bandwidth or cpu at that level of use. Richard ---

Frank, I think that should be the IP of the camera, to forward request to, not a port. Richard ---

Linksys also has a DMZ option, all ports are forwarded to the designated IP. See if your router has that option. Richard ---

@ sschaefer: Does that model have built-in h.264 support? I looked and it seems not to. Only a handful of the Axis cameras do. For sure these do: M1011(-W), M1031-W, P3301(-V), Q1755 and reportedly some other models, but not sure which ones. Richard ---
