A command-line program called uvc-ctrl (http://www.dm9.se/?tag=uvc-ctrl) will actually set the params correctly for *some* recording programs, as long as they don't grab the camera with exclusive access. There is a gui, but it never worked for me. You do need a separate recording program, and I've been playing with variants on the Apple demo 'MyRecorder'. QuicktimeX doesn't work with uvc-ctrl, although PhotoBooth does.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7275378574543326675.post-35594564623347695062013-05-21T04:11:25.474+01:002013-05-21T04:11:25.474+01:00Sadly, I am fighting to find a way to drive my Phi...Sadly, I am fighting to find a way to drive my Phillips SPC900 cam with my Mac running 10.7.5. I downloaded the MACAM app which seems to play nice with the camera, that is until I go to start recording. Then it deposits a ".mov" file on my desktop and promptly quits.<br /><br />So close, yet sooo far...Martynoreply@blogger.comtag:blogger.com,1999:blog-7275378574543326675.post-36591454842936092172013-04-23T20:38:24.358+01:002013-04-23T20:38:24.358+01:00Hi Peter

Worth pointing out that the camera gets stupidly hot - it's worth heatsinking the microsoft chip on the back of the PCB. You can change the settings in the app and then take the image using photo booth - hacky, but works in a pinch.<br /><br />Clearly it's possible to fiddle these settings from within OS X, here's to open source drivers eventually. I'm working on finding a better solution too.<br /><br />JoshJoshhttps://www.blogger.com/profile/10400547057789328697noreply@blogger.comtag:blogger.com,1999:blog-7275378574543326675.post-34181905369258136802013-01-12T20:16:23.971+00:002013-01-12T20:16:23.971+00:00This comment has been removed by a blog administrator.Carl Lydonhttp://www.carllydon.comnoreply@blogger.comtag:blogger.com,1999:blog-7275378574543326675.post-18978516395246441062012-06-05T20:14:01.375+01:002012-06-05T20:14:01.375+01:00Came across this trying to solve a similar problem...Came across this trying to solve a similar problem, but had one slight thing to add…<br /><br />Dominic Szablewski's demo app is hardcoded to select the first video device, which is why it was always using your internal webcam.

Try opening the Mac terminal application (command line window) and running 'system_profiler SPUSBDataType' (no quotes, one command with a space then the argument) to see if you can get the USB identifiers for the webcam inside your Asus monitor (assuming it is USB). There may be a GUI way to do that but I've not checked. Then try Google searching with them. I'd guess drivers from the macam project will be your best bet.Peter Cockhttps://www.blogger.com/profile/00233221181317137855noreply@blogger.comtag:blogger.com,1999:blog-7275378574543326675.post-52047475322925887982012-04-10T00:16:59.534+01:002012-04-10T00:16:59.534+01:00Hi and thx for the helpful posts.

The monitor came with software for windows but no support for Mac. Hard to believe the webcam is NOT UVC, but the Mac OSX just cannot see the camera properly. On some applications it can see the cam but picture is all black.<br /><br />I am looking for a "generic" driver that would allow the web cam to work. Do you think your work would help me? If so, pls let me know.<br /><br />I am not a techie, so if there is code to install, I'd need help.<br /><br />Best<br /><br />JohnAnonymousnoreply@blogger.com
