The IVS Low-Latency Streaming iOS Broadcast SDK provides the interfaces required to broadcast to Amazon IVS on iOS.
The AmazonIVSBroadcast module implements the interface described in this
document. The following operations are supported:
-
Set up (initialize) a broadcast session.
-
Manage broadcasting.
-
Attach and detach input devices.
-
Manage a composition session.
-
Receive events.
-
Receive errors.

How iOS Chooses Camera Resolution and Frame Rate
The camera managed by the broadcast SDK optimizes its resolution and frame rate (frames-per-second, or FPS) to minimize heat production and energy consumption. This section explains how the resolution and frame rate are selected to help host applications optimize for their use cases.
When attaching an IVSCamera to an IVSBroadcastSession, the camera is optimized for a frame rate of
IVSVideoConfiguration.targetFramerate and a resolution of IVSVideoConfiguration.size. These
values are provided to the IVSBroadcastSession on initialization.
