Oddly, I can record very good movies in QuickTime with both sound video.

A recent post indicated Apple and maccam were working on it Updates appreciated Thanks.

Logitech Pro 9000 Code With Drivers

I tried comparing Szablewskis interfacing code with drivers from similar cameras in MaCam, but I couldnt find a single word or number that looked alike between the two.

Any old UVC camera viewer seems to work with this camera on Linux, so I wonder if this camera couldnt be supported through a generic UVC sort of driver, where you simply expose whatever parameter is available.

Most UVC cameras are supported by the Apple built-in UVC driver, and Dominics code allows control of the camera using that driver.

A bigger problem is that the driver architecture has changed, from VDIGs to a kernel-based driver.

Logitech Pro 9000 Full Application Does

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.

Unfortunately, the settings disappear once you quit the application, so its basically useless.

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.

It reconfigures the resolution to one that can sustain 30 FPS (but only in daylight), and the hardware gain is adjustable.

This would be a great app, if only the exposure slider wasnt greyed out for my camera model.

I dont really care about brightness, contrast, saturation or gamma (the hardware already supplies an excellent picture).

What Id like is to adjust the shutter time to 130 or less, to maintain 30 FPS in the evenings.

If my recollection isnt failing me, the exposure is manually adjustable in GUVCView for Linux.

Ive 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.

Im hoping that if I send him the relevant excerpts of Dominics code, he can implement manual exposure for this model.

It was a surprise to learn that webcam support on Mac is this poor, and Apples developer documentation leaves me more confused than I was to begin with.

I can see why Amazon is full of books on MacOS and iOS development now.
