Custom KSControls?

mordy shahar

Hi all,
I'm new to QT and wonder whether I should use it for a cross-os (mainly Linux/Windows) development of in-house tools.

We are in need of sending custom KS-Controls to the camera - the WinRT api allows it in windows.

Is there a way (I'm sure there is) to do it with QT? Can someone point me to a relevant sample?

Is it a reasonably simple task? Is it portable with V4L (Extension units in UVC)?

Thanks,
mordy

Hi and welcome to devnet,

Can you share more information about these KS-Controls ?

Hi,
taken from UVC 1.5 spec
UVC 1.5 Class specification.pdf section 3.7.2.7 - extension unit -
Our hardware (Depth camera) supports various extension unit controls. (Laser-power, Laser-mode etc.)

You can lookup Intel RealSense Camera for more info on those controls.

Windows various api's allows the programmer access to these controls -
the most recent API (WinRT) - with SetDeviceProperty

Since UVC is a standard implemented also on linux - we're tring to figure out some cross platform framework to have in-house apps for tuning/testing etc.

Does QT have support for such controls (UVC extension units)?

And another related question - on windows the Device-MFT plugin can define KS controls- and those allows user apps to communicate with device MFT - e.g. set engineering mode for tuning, set special mode to the camera etc.

This is done via the same api's (with different guid's) and are handled by the device-MFT plugin - so, can we send custom guids with custom buffer?

Thanks,
mordy.

AFAIK, the QtMultimedia module doesn't offer such extensions.

So you are looking for something like librealsense ?

Otherwise, I'd go with implementing a plugin per supported platform.
