2022-09-08qcam: Fix crash when switching from non existant cameraUtkarsh Tiwari
When switching to different camera we try to release the camera previously used. But if that camera has been unplugged, then its instance would have been destroyed. Accessing it leads to seg fault.

2022-09-05qcam: Queue requests only through MainWindow::queueRequest()Utkarsh Tiwari
Currently to request a frame, we operate the camera directly. This approach is also scattered in two places, MainWindow::startCapture() and MainWindow::queueRequest(). This makes it difficult to account for requests. Centralize all the queuing to a single function queueRequest() Rename the current queueRequest() to renderComplete(). This makes more sense as this slot is triggered when the render is complete and we want to queue another request.

Currently we use QInputDialog convenience dialogs to allow the user to select a camera. This doesn't allow adding of more information (such as camera location, model etc). Create a QDialog with a QFormLayout that shows a QComboBox with camera Ids. Use a QDialogButtonBox to provide buttons for accepting and cancelling the action.
