Havent had time to test it enough (read at all) for even an alpha-release yet but to give a hint of what’s in it i’ve uploaded the current documentation to libuvcc.dm9.se.
I’m also writing an obj-c (cocoa) wrapper for the whole thing but that one is not documented yet.
// sluggo
update: regarding the iSight, to get the it into uvc-ctrl menu it has to be active..
update 2: This was originally the release announcement for 1.0a, but i did some minor changes that i realized fixed some really annoying things in that version so i uploaded the new one (1.02a) and just replaced the download link here.. if you’re one of the first five to download the 1.0a version, i’m sorry!
here’s the new alpha version of uvc-ctrl, it looks pretty much as the screenshots in the previous post. function-wise it doesn’t differ much from the last one but it now comes with a native gui localized in english and swedish and is completely dependency-free. note that it’s a status-bar app so no windows are displayed until you select a camera in the menu. there are still some functions missing, most notably the cam-profiles.. also, i’ve only had the chance to test it on 10.6.8. if anyone would like to report success/fail on other os x versions that would be super!
since this is a complete rewrite any and all bug-reports are very welcome, either to sluggo@dm9.se or in the comments below. It would be great if the they included your os x-version, any messages from the Console-app in the Utilities folder (you can filter with the phrase se.dm9) and what led up to it.
lastly, since i wouldn’t be able to draw a stick-figure if my life depended on it there’s no icon!

I’m not quite done with the new version of uvc-ctrl yet but i though i’ll give anyone that’s still interested an update..
the new version is a complete rewrite (not needing libusb and therefore distributed under the dm9 license), two part project. first there’s the uvcc-lib, a library that implements some of the stuff i’ve been missing in QTKit (enumeration of resolutions and fps´, direct access to vendor and device id etc), a few helper functions to tie it up with QTKit (getting a uvccCam struct that can be used to send uvc requests from a [QTCaptureDevice uniqueID] and so on) and of course a uvccSendRequest function. Then there’s the application which will be a status bar (or “menu bar”, dunno the apple lingo here) app capable of setting all the settings on any connected uvc compliant cam.
i thought i’d have this done by now but a work-project turned out occupy most of my summer. now i’m back, just moved into a new apartment and is trying to settle in and study for an exam i screwed up before leaving for the summer break.
next time i post it’ll be the new uvc-ctrl comming out.
update: still some kinks to work out.. but here’s a sneek preview
// sluggo
new version out
not much done but since i got rid of the most annoying thing i figured i’d release it anyway.. here’s what’s done
This version is also compatible with Klaus’ gui.

Klaus has written a gui for the latest version of uvc-ctrl! to use it all you have to do is place the uvc-ctrl in the same folder as his app and you can point-and-click-control your uvc cam. if you wish to bundle uvc-ctrl and Klaus’ gui you just copy it into the app. the easiest way to do that is by unpacking uvc-ctrl and uvc-ctrl-GUI in your home-folder, start the terminal (Applications > Utilities > Terminal) and type
mv uvc-ctrl uvc-ctrl-GUI.app/Contents/MacOS/
and then hit enter.
Thank you Klaus for you awesome work!
note libusb is still required.

new version out
gui available
since people actually seemed to like this and i won’t have time to fix a gui for the new version for some time i’ll publish it without gui.
the new beta fixes some bugs (especially the white balance one) and adds some feats.. no changelog available but here’s what you can get/set if your camera supports it: auto-focus, absolute focus, relative focus, auto-exposure, absolute exposure, absolute iris, relative iris, auto-white balance temperature, absolute white balance temperature, brightness, contrast, gain, saturation and sharpness.
note that the argument order has changed since the last version, think “get/set <value> of <function> on <cam>”. also included the source this time!
the binary included is “universal” (i386/x86_64) and have been tested on both os x 10.6 and 10.7 (thanks to Arvid). the source has also been compiled on freebsd9. it does not require python as that was only the gui. it does however require libusb.
known bugs (thank you Matthew and F-red for the reports)
update thanks to Klaus’ report it seems possible to fix the problem with programs resetting settings made by uvc-ctrl. if you have this trouble: try starting the program that resets your settings, from within it switch to your iSight, update the settings you want with uvc-ctrl on your other cam and then switch back. your settings should now still be in place.

new version out.
codename “ugly-code” is out!
with it you can kill auto-focus/-exposure/-white balance and set the absolute value of these manually on a uvc camera. the gui is really just thrown together and may not recognize your cam if it returns any error in the get-all request of uvcc.app/Contents/Resources/uvc-ctrl. it does however work nicely with the logitech c910 (on both x86_64 and i386 snowy leopards). a screenshot is available in the earlier post about it.
oh, and i stole the icon from somewhere on the internet.. can’t even remember where!
note: requires python 2.6, shipped with os x 10.6 – snowy leopard. so if you are running os x 10.5 you can update your python installation, or just wait.. ill get a new, python >= 2.5 version up in a while.
note 2: found a bug, the auto exposure slide should go from 1 to 8. selecting 0 will cause an error that goes unnoticed by (well, not that unnoticed.. you’ll notice the setting wasn’t saved)!
note 3: got some reports it isn’t working.. it seems alotta progs that use a webcam resets all settings (and thus turns on auto-whatever) when opened. This may very well be an apple driver “feat” but most people i’ve spoken with says it works well if they turn off the auto-whatever after starting said program.
btw, beer is good.
