IVSMultiSourceDevice

Objective-C

@protocol IVSMultiSourceDevice <IVSDevice>

Swift

protocol IVSMultiSourceDevice : IVSDevice

Represents an input device such as a camera or microphone with multiple underlying input sources.


                    
                    
                    -listAvailableInputSources

List available underlying input sources for the device.

Declaration

Objective-C

- (nonnull NSArray<IVSDeviceDescriptor *> *)listAvailableInputSources;

Swift

func listAvailableInputSources() -> [IVSDeviceDescriptor]


                    
                    
                    -setPreferredInputSource:onComplete:

Sets the preferred input source.

The preferred input source of a camera device will always take effect if no error occurs. The preferred input source of a microphone device may take effect if the system allows it and no error occurs.

Declaration

Objective-C

- (void)setPreferredInputSource:(nonnull IVSDeviceDescriptor *)inputSource
                     onComplete:
                         (nullable void (^)(NSError *_Nullable))onComplete;

Swift

func setPreferredInputSource(_ inputSource: IVSDeviceDescriptor, onComplete: ((Error?) -> Void)? = nil)

Parameters

`inputSource`	The preferred input source.
`onComplete`	A callback that that contains any error that occurred while updating the preferred input source. Invoked when the operation has completed. Always invoked on the main queue.
