◆ AgoraConnectionState

enum AgoraConnectionState

Connection states.

Enumerator
AgoraConnectionStateDisconnected	1: The SDK is disconnected from the Agora edge server. The state indicates the SDK is in one of the following phases: Theinitial state before calling the `joinChannelByToken:channelId:uid:mediaOptions:joinSuccess:` method. The app calls the `leaveChannel:` method.
AgoraConnectionStateConnecting	2: The SDK is connecting to the Agora edge server. This state indicates that the SDK is establishing a connection with the specified channel after the app calls `joinChannelByToken:channelId:uid:mediaOptions:joinSuccess:`. If the SDK successfully joins the channel, it triggers the `rtcEngine:connectionChangedToState:reason:` callback and the connection state switches to AgoraConnectionStateConnected. After the connection is established, the SDK also initializes the media and triggers `rtcEngine:didJoinChannel:withUid:elapsed:` when everything is ready.
AgoraConnectionStateConnected	3: The SDK is connected to the Agora edge server. This state also indicates that the user has joined a channel and can now publish or subscribe to a media stream in the channel. If the connection to the channel is lost because, for example, if the network is down or switched, the SDK automatically tries to reconnect and triggers `rtcEngine:connectionChangedToState:reason:` callback, notifying that the current network state becomes AgoraConnectionStateReconnecting.
AgoraConnectionStateReconnecting	4: The SDK keeps reconnecting to the Agora edge server. The SDK keeps rejoining the channel after being disconnected from a joined channel because of network issues. If the SDK cannot rejoin the channel within 10 seconds, it triggers `rtcEngineConnectionDidLost:`, stays in the AgoraConnectionStateReconnecting state, and keeps rejoining the channel. If the SDK fails to rejoin the channel 20 minutes after being disconnected from the Agora edge server, the SDK triggers the `rtcEngine:connectionChangedToState:reason:` callback, switches to the AgoraConnectionStateFailed state, and stops rejoining the channel.
AgoraConnectionStateFailed	5: The SDK fails to connect to the Agora edge server or join the channel. This state indicates that the SDK stops trying to rejoin the channel. You must call `leaveChannel:` to leave the channel. You can call `joinChannelByToken:channelId:uid:mediaOptions:joinSuccess:` to rejoin the channel. If the SDK is banned from joining the channel by the Agora edge server through the RESTful API, the SDK triggers the `rtcEngine:connectionChangedToState:reason:` callback.

The AgoraDegradationBalanced has a lower reduction than AgoraDegradationMaintainQuality and AgoraDegradationMaintainFramerate, and this preference is suitable for scenarios where both smoothness and video quality are a priority. Note The resolution of the video sent may change, so remote users need to handle this issue. See `rtcEngine:videoSizeChangedOfSourceType:uid:size:rotation:`.

◆ AgoraApplicationScenarioType

enum AgoraApplicationScenarioType

The video application scenarios.

Since: v4.2.0

Enumerator
AgoraApplicationGeneralScenario	0: (Default) The general scenario.
AgoraApplicationMeetingScenario	1: The meeting scenario. `AgoraApplicationMeetingScenario` (1) is suitable for meeting scenarios. The SDK automatically enables the following strategies: In meeting scenarios where low-quality video streams are required to have a high bitrate, the SDK automatically enables multiple technologies used to deal with network congestions, to enhance the performance of the low-quality streams and to ensure the smooth reception by subscribers. The SDK monitors the number of subscribers to the high-quality video stream in real time and dynamically adjusts its configuration based on the number of subscribers. If nobody subscribers to the high-quality stream, the SDK automatically reduces its bitrate and frame rate to save upstream bandwidth. If someone subscribes to the high-quality stream, the SDK resets the high-quality stream to the `AgoraVideoEncoderConfiguration` configuration used in the most recent calling of `setVideoEncoderConfiguration:`. If no configuration has been set by the user previously, the following values are used: On iOS: Resolution: 960 × 540 Frame rate: 15 fps Bitrate: 1000 Kbps On macOS: Resolution: 1280 × 720 Frame rate: 15 fps Bitrate: 1600 Kbps The SDK monitors the number of subscribers to the low-quality video stream in real time and dynamically enables or disables it based on the number of subscribers. If nobody subscribes to the low-quality stream, the SDK automatically disables it to save upstream bandwidth. If someone subscribes to the low-quality stream, the SDK enables the low-quality stream and resets it to the `AgoraSimulcastStreamConfig` configuration used in the most recent calling of `setDualStreamMode:streamConfig:`. If no configuration has been set by the user previously, the following values are used: Resolution: 480 × 272 Frame rate: 15 fps Bitrate: 500 Kbps Note If the user has called `setDualStreamMode:streamConfig:` to set that never send low-quality video stream ( `AgoraDisableSimulcastStream` ), the dynamic adjustment of the low-quality stream in meeting scenarios will not take effect.
AgoraApplication1V1Scenario	2: 1v1 video call scenario. `AgoraApplication1V1Scenario` (2) This is applicable to the `one to one live` scenario. To meet the requirements for low latency and high-quality video in this scenario, the SDK optimizes its strategies, improving performance in terms of video quality, first frame rendering, latency on mid-to-low-end devices, and smoothness under weak network conditions. Note This enumeration value is only applicable to the broadcaster vs. broadcaster scenario.
AgoraApplicationLiveShowScenario	Live show scenario. `AgoraApplicationLiveShowScenario` (3) This is applicable to the `show room` scenario. In this scenario, fast video rendering and high image quality are crucial. The SDK implements several performance optimizations, including automatically enabling accelerated audio and video frame rendering to minimize first-frame latency (no need to call `enableInstantMediaRendering` ), and B-frame encoding to achieve better image quality and bandwidth efficiency. The SDK also provides enhanced video quality and smooth playback, even in poor network conditions or on lower-end devices.

◆ AgoraAudioProcessChannels

enum AgoraAudioProcessChannels

The number of channels for audio preprocessing.

In scenarios that require enhanced realism, such as concerts, local users might need to capture stereo audio and send stereo signals to remote users. For example, the singer, guitarist, and drummer are standing in different positions on the stage. The audio capture device captures their stereo audio and sends stereo signals to remote users. Remote users can hear the song, guitar, and drum from different directions as if they were at the auditorium. You can set the dual-channel processing to implement stereo audio in this class. Agora recommends the following settings:1. Preprocessing: call setAdvancedAudioOptions: and set audioProcessingChannels to AgoraAudioProcessChannelstereo (2) in AgoraAdvancedAudioOptions.

Post-processing: call setAudioProfile: and set profile to AgoraAudioProfileMusicStandardStereo (3) or AgoraAudioProfileMusicHighQualityStereo (5).

Note

The stereo setting only takes effect when the SDK uses the media volume.
On iOS, the minimum version of system for stereo sound is 14.0. The minimum device requirements are as follows:
- iPhone XS
- iPhone XS Max
- iPhone XR
- iPhone 11
- iPhone 11 Pro
- iPhone 11 Pro Max
- iPhone SE (2020)
- iPad Pro 11" and 12.9" (3rd generation)
- iPad Pro 11" and 12.9" (4th generation)

Enumerator

Note: If AgoraAudioTrackTypeDirect is specified for this parameter, you must set publishMicrophoneTrack to NO in AgoraRtcChannelMediaOptions when calling joinChannelByToken:channelId:uid:mediaOptions:joinSuccess: to join the channel; otherwise, joining the channel fails and returns the error code -2.
