|
|
Retrieving AVCaptureDevice is a flaky operation. Thus create capture device resolver to make our code more robust.
|
|
|
|
Resolver is used to retrieve AVCaptureDevice. We are going to do our best to find the camera for you.
|
|
|
|
Resolver is only going to be used by SCManagedCaptureDevice.
|
|
|
|
All APIs are thread safe.
