@interface IVSMixerConfiguration : NSObject

    Swift

    class IVSMixerConfiguration : NSObject

  • An object to broadcast, transform, and distribute audio video content. Changing any properties on this object after providing it to IVSBroadcastSession will not have any effect. A copy of the configuration is made and kept internally. To make changes to the session live, use the IVSBroadcastSession.mixer APIs, or IVSBroadcastSession.setLogLevel.

    Declaration

    Objective-C

    
@interface IVSBroadcastConfiguration : NSObject

    Swift

    class IVSBroadcastConfiguration : NSObject

  • BroadcastSession is the primary interaction point with the IVS Broadcast SDK. You must create a BroadcastSession in order to begin broadcasting.

    Note

    If there as a live broadcast when this object deallocates, internally stop will be called during deallocation, and it will block until the stream has been gracefully terminated or a timeout is reached. Because of that it is recommended that you always explicitly stop a live broadcast before deallocating.

@interface IVSLocalStageStreamVideoConfiguration : NSObject

    Swift

    class IVSLocalStageStreamVideoConfiguration : NSObject

  • The mixer determines the final on-screen and in-ear state for visual elements and audio.

    An element is represented by an IVSMixerSlotConfiguration that has a number of associated parameters to place an image stream spatially and set the gain of an audio stream from a device.

    Each slot can be bound to a single image device (such as a camera) and a single audio device (such as a microphone).

    Declaration

    Objective-C

    
@interface IVSPresets : NSObject

    Swift

    class IVSPresets : NSObject

  • This is a streamlined version of an IVSBroadcastSession to be used in a Broadcast Upload Extension. The extensions are under strict memory constraints, and this class removes some of the SDK features in exchange for a reduction in memory footprint.

    For example, there are no attach or detach APIs. There are 3 devices created for you, corresponding to the screen, app audio, and the microphone. Pass CMSampleBuffers to these devices from your RPBroadcastSampleHandler implementation. In addition, there is no mixer configuration and no access to an IVSMixer. This class does not support multiple image layers, and the primary layer (the device screen) is always sized to the full output stream scaled to fit. Transparency is also disabled regardless of what is provided in the video configuration.

    Finally, you can not create a preview for the systemImageSource or the session as a whole, they will not render anything.

    Note

    this will automatically set IVSBroadcastSession.applicationAudioSessionStrategy to noAction.

@interface IVSStageStream : NSObject

    Swift

    class IVSStageStream : NSObject

  • IVSTransmissionStatistics contains statistics on the broadcast’s current measured bitrate, recommended bitrate by the SDK’s adaptive bitrate algorithm, average round trip time, broadcast quality (relative to configured minimum and maximum bitrates), and network health.

    Expect this callback to be triggered on IVSBroadcastSession.delegate quite frequently (approximately twice per second) as the measured and recommended bitrates change. Measured versus recommended bitrate behavior can vary significantly between platforms. The documentation on each metric provides instructions on how to interpret these values.
