Not able to access camera controls about nokhwa HOT 3 CLOSED

The problem with CameraControls is that its implementation by each backend(MSMF, AVF, V4L2) is inconsistent, however you may have neglected camera_control() and its related methods. You have the best shot with the native backends for each OS, except AVFondation where I couldn't get through Apples documentation (PRs welcome!)

Let me know if you need any more help/find any bugs with this.

Alright thanks, I didn't realize that backends could be explicitly instantiated. For posterity, the following code works for my purposes

let mut camera: Box<dyn CaptureBackendTrait + Sync + Send> = Box::new({
    #[cfg(unix)]
    { nokhwa::backends::capture::V4LCaptureDevice::new(0, None) }
    #[cfg(windows)]
    { nokhwa::backends::capture::MediaFoundationCaptureDevice::new(0, None) }
}?);

The Camera struct is a wrapper for the CaptureBackendTrait object. In the next release, I will add the necessary APIs to the Camera struct itself.

Open a new issue if you encounter a bug.
