Ah, good question! I should be able to implement something like that without too much trouble. Let me give it a try.

BTW, I should also say that I've been doing some more testing; I originally assumed that I should avoid just displaying the entire stream full-blast, to avoid consuming all network and CPU bandwidth. But, I've been testing an instance of Fettuccine displaying a mjpeg webcam as fast as the data comes in, and the N900 is holding up fine. (It's getting a little warm after over a half hour of constant use, but so far it doesn't seem dangerously hot.) So, here's another question -- is there any value to not displaying a streaming webcam at full speed?

(I've gotta admit, it's also quite nice to watch the stream running on the task manager screen; the video libraries I've been using in my other apps use rather ugly tricks to optimize the speed with which they send data to XWindows, which normally break down when you open up the task manager. Fettuccine, on the other hand, is simply redrawing an image over and over again... )
