IVSTransmissionStatistics
Objective-C
@interface IVSTransmissionStatistics : NSObject
Swift
class IVSTransmissionStatistics : 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.

Declaration

IVS_INIT_UNAVAILABLE
-
The current measured average sending bitrate. Note that the device’s video encoder is often unable to match exactly the SDK’s recommended bitrate. There can be some delay between the SDK’s recommended bitrate and the video encoder responding to the recommendation.
Declaration
Objective-C
@property (nonatomic, readonly) double measuredBitrate;
Swift
var measuredBitrate: Double { get }
-
The bitrate currently recommended by the SDK. Depending on network conditions, the SDK may recommend a higher or lower bitrate to preserve the stability of the broadcast, within the constraints of the minimum, maximum, and initial bitrates configured by the application in BroadcastConfiguration.
Declaration
Objective-C
@property (nonatomic, readonly) double recommendedBitrate;
Swift
var recommendedBitrate: Double { get }
-
The current average round trip time for network packets (not image or audio samples).
