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)?
Hi and welcome to devnet,
Can you share more information about these KS-Controls ?
taken from UVC 1.5 spec
UVC 1.5 Class specification.pdf section 220.127.116.11 - 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?
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.
