I can see why Amazon is full of books on MacOS and iOS development now.Ptz camera controller app ptz camera controller app The pan tilt zoom controls work over WIFI and cellular networks (3G, 4G, LTE, etc. It was a surprise to learn that webcam support on Mac is this poor, and Apple's developer documentation leaves me *more* confused than I was to begin with. All this googling, downloading of source code and emailing of programmers is giving me flashbacks to my days of attempting to use Linux as my main OS. I couldn't see any code for gain/exposure adjustment in Macam, so I'm suspecting I'd be out of luck, even if it did support my camera. #Uvc driver mac os x download manual#I'm hoping that if I send him the relevant excerpts of Dominic's code, he can implement manual exposure for this model. I've been googling for a command line tool that lets me dump all the supported parameters from a UVC camera, together with any hex IDs needed to control them, but I have come up empty-handed. I bought his app, since it did support one of the features I wanted (hardware gain), and I'm about to pop off an email to him about the manual exposure. If my recollection isn't failing me, the exposure is manually adjustable in GUVCView for Linux. ![]() ![]() What I'd like is to adjust the shutter time to 1/30 or less, to maintain 30 FPS in the evenings. I don't really care about brightness, contrast, saturation or gamma (the hardware already supplies an excellent picture). This would be a great app, if only the exposure slider wasn't greyed out for my camera model. It reconfigures the resolution to one that can sustain 30 FPS (but only in daylight), and the hardware gain is adjustable. Webcam Settings by Mactaris ( ) works with my camera, and other UVC cameras, but seems to take the approach of somehow attaching to the existing UVC device to modify its settings, instead of providing its own device. I assume that the way you acquire an image stream is the same for all UVC cameras, even if resolutions and color spaces vary somewhat. Unfortunately, the settings disappear once you quit the application, so it's basically useless. His full application does deal with the image stream, I think, as it displays actual video from the camera, though it might be using some Mac OS X API for that. ![]() If anybody knows how I'd begin to add support for this camera to MaCam, I'd really like to have a talk to them.Īha! I suspected that, as I couldn't see any files called "UVC" in your source code. Any old UVC camera viewer seems to work with this camera on Linux, so I wonder if this camera couldn't be supported through a generic UVC sort of driver, where you simply expose whatever parameter is available? #Uvc driver mac os x download pro#What I do know is that UVC cameras have this standard way of setting parameters and apparently the parameter names and value ranges can be queried from the USB device, and that this sort of parameter is what the Logitech Quickcam Pro 9000 uses. #Uvc driver mac os x download drivers#I tried comparing Szablewski's interfacing code with drivers from similar cameras in MaCam, but I couldn't find a single word or number that looked alike between the two. I'm not familiar with USB driver programming at all, and I'm new to Objective-C and Cocoa. This camera supports the following settings in UVC mode:ĭominic Szablewski has already done the ground work, and posted an open source controller and viewer application for the Logitech Quickcam Pro 9000 back in 2009: ![]()
