/*
|

In general, the function of SCCapturer is to use some resources (such as SCManagedCapturerListenerAnnouncer), to do
|
||||
something (such as announce an event).
|
||||
|
||||
SCCaptureResource abstract away the "resources" part of SCCapturer. It has no APIs itself, it is used to be the
|
||||
resource which gets passed arround for capturer V2 state machine.

/*
|

In general, the function of SCCapturer is to use some resources (such as SCManagedCapturerListenerAnnouncer), to do
|
||||
something (such as announce an event).
|
||||
|
||||
SCCaptureWorker abstract away the "do something" part of SCCapturer. It has very little internal states/resources.
|
||||
|
||||
SCCaptureWorker is introduced to be shared between CaptureV1 and CaptureV2, to minimize duplication code.
