You just get the app from https://github.com/bakercp/IPCAM2SYPHON/downloads . It comes with 15 streams ready for testing. And the output gets relayed to Max via Syphon. But you can start playing (by editing it) with the streams.xml file that comes with the app.
For anyone wanting to play, just go ahead.
My problem is I cannot use my camera which is not an Axis camera with IPCAM2SYPHON. It is a wireless camera which comes with its own Access Point. With an IP Camera application (EvoCam in my case), I just connect to it by setting its ip and port (http://IPADDRESS:PORT) and path (/video.cgi) Username and Password and it just works. I set up my camera and another camera for testing purposes. See image_1.png to see that they both output images.
Now in IPCAM2SYPHON (see image_2.png), I see that the app receives bytes from the camera but it does not show any images. The test camera outputs images just fine. This is the simplified (only 2 cameras, mine and one for testing purposes) streams.xml file I am using (I edited out otherwise the forum does not let me paste them):
