Note: In the COMMUNICATION channel profile, the resolution of the video sent may change, so remote users need to handle this issue. See onVideoSizeChanged.

MAINTAIN_FRAMERATE

1: Prefers to reduce the video quality while maintaining the video frame rate during video encoding under limited bandwidth. This degradation preference is suitable for scenarios where smoothness is prioritized and video quality is allowed to be reduced.

MAINTAIN_BALANCED

2: Reduces the video frame rate and video quality simultaneously during video encoding under limited bandwidth. MAINTAIN_BALANCED has a lower reduction than MAINTAIN_QUALITY and MAINTAIN_FRAMERATE, 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 onVideoSizeChanged.

◆ STREAM_FALLBACK_OPTIONS

enum agora::rtc::STREAM_FALLBACK_OPTIONS

1: Under poor downlink network conditions, the remote video stream, to which you subscribe, falls back to the low-stream (low resolution and low bitrate) video. You can set this option only in the setRemoteSubscribeFallbackOption method. Nothing happens when you set this in the setLocalPublishFallbackOption method.

STREAM_FALLBACK_OPTION_AUDIO_ONLY

2: Under poor uplink network conditions, the published video stream falls back to audio only.

Under poor downlink network conditions, the remote video stream, to which you subscribe, first falls back to the low-stream (low resolution and low bitrate) video; and then to an audio-only stream if the network conditions worsen.

CONNECTION_STATE_CONNECTING	2: The SDK is connecting to Agora's edge server. When the application calls the joinChannel method, the SDK starts to establish a connection to the specified channel, triggers the onConnectionStateChanged callback, and switches to the CONNECTION_STATE_CONNECTING state. When the SDK successfully joins the channel, it triggers the onConnectionStateChanged callback and switches to the CONNECTION_STATE_CONNECTED state. After the SDK joins the channel and when it finishes initializing the media engine, the SDK triggers the onJoinChannelSuccess callback.
CONNECTION_STATE_CONNECTED	3: The SDK is connected to Agora's edge server and has joined a channel. You 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: The onConnectionInterrupted callback (deprecated). The onConnectionStateChanged callback and switches to the CONNECTION_STATE_RECONNECTING state.
CONNECTION_STATE_RECONNECTING	4: 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 after being disconnected from Agora's edge server, the SDK triggers the onConnectionLost callback, stays in the CONNECTION_STATE_RECONNECTING state, and keeps rejoining the channel. If the SDK fails to rejoin the channel 20 minutes after being disconnected from Agora's edge server, the SDK triggers the onConnectionStateChanged callback, switches to the CONNECTION_STATE_FAILED state, and stops rejoining the channel.
CONNECTION_STATE_FAILED	5: The SDK fails to connect to Agora's edge server or join the channel. You must call the leaveChannel method to leave this state, and call the joinChannel method again to rejoin the channel. If the SDK is banned from joining the channel by Agora's edge server (through the RESTful API), the SDK triggers the onConnectionBanned (deprecated) and onConnectionStateChanged callbacks.

CONNECTION_CHANGED_INTERRUPTED	2: The connection between the SDK and Agora's edge server is interrupted.
CONNECTION_CHANGED_BANNED_BY_SERVER	3: The connection is banned by the server. This occurs when the server calls the Banning user privileges API to kick the user out of the channel. You can display a pop-up box in the application that says: "The user has been banned from this channel."
CONNECTION_CHANGED_JOIN_FAILED	4: The SDK fails to join the channel. This occurs when the SDK fails to rejoin the channel within 20 minutes after receiving the onConnectionStateChanged(CONNECTION_STATE_RECONNECTING, CONNECTION_CHANGED_INTERRUPTED) callback and stops trying. You can display a pop-up box in the application that says: "Failed to join the channel due to network issues. Please try to rejoin the channel after switching to a different network."
CONNECTION_CHANGED_LEAVE_CHANNEL	5: The SDK has left the channel.
CONNECTION_CHANGED_INVALID_APP_ID	6: The specified App ID is invalid. Check whether the App ID used by the user is the same as the App ID obtained from the Agora Console, and then try to rejoin the channel with a valid App ID.
CONNECTION_CHANGED_INVALID_CHANNEL_NAME	7: The specified channel name is invalid. The channel name cannot be empty nor longer than 64 bytes in length. For supported characters, see the `channelName` parameter in joinChannel. You can display a pop-up box in the application that says: "The channel name is invalid. Please try to rejoin the channel with a valid channel name."
CONNECTION_CHANGED_INVALID_TOKEN	8: The token is invalid, probably due to the following reasons: The App Certificate for the project is enabled in the Agora Console, but you do not use a token to authenticate the user when calling joinChannel. When the App Certificate for a project is enabled, you must use tokens to authenticate users. The user ID that you specify in the joinChannel method is different from the user ID that you pass for generating the token. Check whether the token used by the user is the same as the token generated at your app server, and then try to rejoin the channel with a valid token.
CONNECTION_CHANGED_TOKEN_EXPIRED	9: The token has expired. The user using the expired token is forced to leave the channel. The app client needs to request a new token from the app server and then try to rejoin the channel with the new token.
CONNECTION_CHANGED_REJECTED_BY_SERVER	10: The user is banned by the server. This error usually occurs in the following situations: When the user is already in the channel, and still calls the method to join the channel, for example, joinChannel. When the user tries to join a channel during startEchoTest. Once you call startEchoTest, you need to call stopEchoTest before joining a channel.
CONNECTION_CHANGED_SETTING_PROXY_SERVER	11: The SDK tries to reconnect after setting a proxy server.
CONNECTION_CHANGED_RENEW_TOKEN	12: The token renews.
CONNECTION_CHANGED_CLIENT_IP_ADDRESS_CHANGED	13: Due to a change of the network type, IP address, or network port, the client IP address has changed, and the SDK tries to reconnect. If this state occurs multiple times, you can display a pop-up box in the application that says: "The network connection is not stable. Please switch to another network."
CONNECTION_CHANGED_KEEP_ALIVE_TIMEOUT	14: Timeout for the keep-alive of the connection between the SDK and Agora's edge server. The connection state changes to CONNECTION_STATE_RECONNECTING(4).
CONNECTION_CHANGED_SAME_UID_LOGIN	19: Join the same channel from different devices using the same user ID. Since v3.7.0
CONNECTION_CHANGED_TOO_MANY_BROADCASTERS	20: The number of hosts in the channel is already at the upper limit. Note This enumerator is reported only when the support for 128 users is enabled.
