I'm using Instant Webcam for ios and it's very easy to use in the sense that you just type in the IP in the URL bar and it shows you the stream. I'd like to use the stream in other programs, specifically MAX/MSP, so I need to know the actual file name for the stream. Like video.mpeg, but I can't find it! I've looked through the source a bit to no avail. Any tips on how I might find this?

Maybe looking at the page resources could give you some insight in where the stream is coming from?
