According to the following Qt 5.15 pages at qt.io, the QCameraControl, QMediaControl, QMediaService classes are obsolete:
- https://doc.qt.io/qt-5/qcameracontrol.html
- https://doc.qt.io/qt-5/qmediacontrol.html
- https://doc.qt.io/qt-5/qmediaservice.html
Unfortunately, I don't see mention of replacements for these however.
I'm of the understanding that these (and similar classes) were available for writing back-end support for cameras that aren't already supported by Qt.
My question then is: in Qt 5.15 and newer, what Qt classes, functions, or other mechanisms can/should be used instead to provide support for cameras that Qt doesn't already support?
