I'm afraid I can't help with saving the video stream or using Cygwin as I haven't tried to do either and I just don't know whats involved. Both sound perfectly feasible to me...

Forgive my ignorance on the issues involved, I didnt not read everything I could on this. Does it or is it possible to get the sound on the video stream. QuickCam Pro 9000 seems to have a mic. Is it part of the video? Another question is, from what I read most of people opening video in the browser, but what if I want to save the files on the network location. I am assuming this should be pretty easy. Finally, do I have to have linux on the host computer as you say or can I get by with cygwin ? Thank you for your awesome efforts ! This is great.

However, as recently as today -- with the newest version of gphoto2, I have still not coaxed my Nikon Coolpix digital cameras to work on that platform. At the same time, I have recently switched my mother's laptop from WinXP to Fedora Linux, and the nice Logitech 'Fusion' webcam (uvc based) refuses to work for 'everyday' uses like Skype, so I gave her one of my 'pwc based' cameras instead. Fast forward to now: a use for my NSLU2 devices, and I find that my 'flakey' fusion webcam seems to work just fine with your project! My only confusion was that I had to reboot the device before the 'MJPG-streamer' page would show up. Also, in the previous column Lance mentioned installing 'webif' ,which I also did (it appears that the instructions were here: http://www.nslu2-linux.org/wiki/OpenWrt/BuildInstructions). However, I am not sure how to use it -- the 'main' webpages are in the '/webcam_www' directory, whereas the webif stuff is in '/www'. I thought that I would be able to use logical links to lump them together, but I cannot make it work. I am so pleased that I stumbled across this site! :)

Once that was working I would simply try running two invocations of mjpg-streamer on two different ports (e.g port 80 and port 8080). Its not very elegant, but as far as I can tell it should work. I haven't tried motion on the NSLU2, but I suspect you would have to cut the resolution and the frame rate down a lot to get it to work, even at 266MHz.

As in: http://www.nslu2-linux.org/wiki/HowTo/UseTwoBusPoweredDevices Would the software changes be in the source, or is it a matter of settings? This would be very useful. At the mjpg-streamer site it is recommended that for opening the stream to the internet, one use the program "motion". Have you tried anything like that? John,

It requires a simple hardware mod (adding one jumper) and some software changes. But in principle I can't see why not. I need to get hold of two cameras to try it out. I’m looking into that.

I would guess that the way to feed other programs with images would be via the output-file.so plugin and the useful '-c command' option, but as I haven't experimented with this I know no more than that.
