Releases all IRtcEngine resources.
Use this method for apps in which users occasionally make voice or video calls. When users do not make calls, you can free up resources for other operations. Once you call release to destroy the created IRtcEngine instance, you cannot use any method or callback in the SDK any more. If you want to use the real-time communication functions again, you must call createAgoraRtcEngine and initialize to create a new IRtcEngine instance.

pure virtual |
Sets the channel profile of the Agora IRtcEngine.
After initialization, the SDK uses the CHANNEL_PROFILE_COMMUNICATION channel profile by default. You can call this method to set the channel profile. The Agora IRtcEngine differentiates channel profiles and applies optimization algorithms accordingly. For example, it prioritizes smoothness and low latency for a video call, and prioritizes video quality for the interactive live video streaming.
| profile | The channel profile of the Agora IRtcEngine. See CHANNEL_PROFILE_TYPE |
|
pure virtual |
Sets the role of the user in interactive live streaming.
After calling setChannelProfile (CHANNEL_PROFILE_LIVE_BROADCASTING), the SDK sets the user role as audience by default. You can call setClientRole to set the user role as host.
You can call this method either before or after joining a channel. If you call this method to switch the user role after joining a channel, the SDK automatically does the following:
LIVE_BROADCASTING profile only.| role | The role of a user in interactive live streaming. See CLIENT_ROLE_TYPE. |
joinChannel with the options parameter and use the default settings publishLocalAudio = true or publishLocalVideo = true.setClientRole to set the user role as host.muteLocalAudioStream(false) or muteLocalVideoStream(false).

Sets the role of the user in interactive live streaming.
In the LIVE_BROADCASTING channel profile, the SDK sets the user role as audience by default. You can call setClientRole to set the user role as host.
You can call this method either before or after joining a channel. If you call this method to switch the user role after joining a channel, the SDK automatically does the following:

| options | The detailed options of a user, including user level. See ClientRoleOptions. |
joinChannel with the options parameter and use the default settings publishLocalAudio = true or publishLocalVideo = true.setClientRole to set the user role as host.muteLocalAudioStream(false) or muteLocalVideoStream(false).
|
pure virtual |
Joins a channel with the user ID.
Users in the same channel can talk to each other, and multiple users in the same channel can start a group chat. Users with different App IDs cannot call each other.
You must call the leaveChannel method to exit the current call before entering another channel.
A successful joinChannel method call triggers the following callbacks:
COMMUNICATION profile, or is a host in the LIVE_BROADCASTING profile.When the connection between the client and Agora's server is interrupted due to poor network conditions, the SDK tries reconnecting to the server. When the local client successfully rejoins the channel, the SDK triggers the onRejoinChannelSuccess callback on the local client.
Once the user joins the channel (switches to another channel), the user subscribes to the audio and video streams of all the other users in the channel by default, giving rise to usage and billing calculation. If you do not want to subscribe to a specified stream or all remote streams, call the mute methods accordingly.
uid. If you set uid as 0, the system automatically assigns a uid. If you want to join a channel from different devices, ensure that each device has a different uid. | token | The token generated at your server. See Authenticate Your Users with Tokens. |
| channelId | Pointer to the unique channel name for the Agora RTC session in the string format smaller than 64 bytes. Supported characters:
|
| info | (Optional) Pointer to additional information about the channel. This parameter can be set to NULL or contain channel related information. Other users in the channel will not receive this message. |
| uid | (Optional) User ID. A 32-bit unsigned integer with a value ranging from 1 to 232-1. The uid must be unique. If a uid is not assigned (or set to 0), the SDK assigns and returns a uid in the onJoinChannelSuccess callback. Your application must record and maintain the returned uid, because the SDK does not do so. |

options parameter, which configures whether the user publishes or automatically subscribes to the audio and video streams in the channel when joining the channel. By default, the user publishes the local audio and video streams and automatically subscribes to the audio and video streams of all the other users in the channel. Subscribing incurs all associated usage costs. To unsubscribe, set the options parameter or call the mute methods accordingly.IRtcEngine object.| token | The token generated at your server.

| uid | (Optional) User ID. A 32-bit unsigned integer with a value ranging from 1 to 232-1. The uid must be unique. If a uid is not assigned (or set to 0), the SDK assigns and returns a uid in the onJoinChannelSuccess callback. Your application must record and maintain the returned uid, because the SDK does not do so. Note: The ID of each user in the channel should be unique. If you want to join the same channel from different devices, ensure that the user IDs in all devices are different. |

Switches to a different channel.
This method allows the audience of a LIVE_BROADCASTING channel to switch to a different channel.
After the user successfully switches to another channel, the onLeaveChannel and onJoinChannelSuccess callbacks are triggered to indicate that the user has left the original channel and joined a new one.
Once the user switches to another channel, the user subscribes to the audio and video streams of all the other users in the channel by default, giving rise to usage and billing calculation. If you do not want to subscribe to a specified stream or all remote streams, call the mute methods accordingly.

Allows a user to leave a channel, such as hanging up or exiting a call.
After joining a channel, the user must call the leaveChannel method to end the call before joining another channel.
This method returns 0 if the user leaves the channel and releases all resources related to the call.
This method call is asynchronous, and the user has not left the channel when the method call returns. Once the user leaves the channel, the SDK triggers the onLeaveChannel callback.
A successful leaveChannel method call triggers the following callbacks:
COMMUNICATION channel, or is a host in the LIVE_BROADCASTING profile.

Registers a user account.
Once registered, the user account can be used to identify the local user when the user joins the channel. After the user successfully registers a user account, the SDK triggers the onLocalUserRegistered callback on the local client, reporting the user ID and user account of the local user.
To join a channel with a user account, you can choose either of the following:
The difference between the two is that for the former, the time elapsed between calling the joinChannelWithUserAccount method and joining the channel is shorter than the latter.

Starts an audio and video call loop test.
Before joining a channel, to test whether the user's local sending and receiving streams are normal, you can call this method to perform an audio and video call loop test, which tests whether the audio and video devices and the user's upstream and downstream networks are working properly.
After starting the test, the user needs to make a sound or face the camera. The audio or video is output after about two seconds. If the audio playback is normal, the audio device and the user's upstream and downstream networks are working properly; if the video playback is normal, the video device and the user's upstream and downstream networks are working properly.

Sets the Agora cloud proxy service.
When users' network access is restricted by a firewall, configure the firewall to allow specific IP addresses and ports provided by Agora; then, call this method to enable the cloud proxy and set the cloud proxy type with the proxyType parameter.
After a successfully cloud proxy connection, the SDK triggers the onConnectionStateChanged (CONNECTION_STATE_CONNECTING, CONNECTION_CHANGED_SETTING_PROXY_SERVER) callback.
As of v3.6.2, when a user calls this method and then joins a channel successfully, the SDK triggers the onProxyConnected callback to report the user ID, the proxy type connected, and the time elapsed from the user calling joinChannel until this callback is triggered.
To disable the cloud proxy that has been set, call setCloudProxy(NONE_PROXY). To change the cloud proxy type that has been set, call setCloudProxy(NONE_PROXY) first, and then call setCloudProxy with the desired proxyType.
| proxyType | The cloud proxy type, see CLOUD_PROXY_TYPE. This parameter is required, and the SDK reports an error if you do not pass in a value. |
-2(ERR_INVALID_ARGUMENT): The parameter is invalid.-7(ERR_NOT_INITIALIZED): The SDK is not initialized.

Initializes the local video view.
This method initializes the video view of a local stream on the local device. It affects only the video view that the local user sees, not the published local video stream.
Call this method to bind the local video stream to a video view and to set the rendering and mirror modes of the video view. The binding is still valid after the user leaves the channel, which means that the window still displays. To unbind the view, set the view in VideoCanvas to NULL.
| canvas | Pointer to the local video view and settings. See VideoCanvas. |

Initializes the video view of a remote user.
This method initializes the video view of a remote stream on the local device. It affects only the video view that the local user sees.
Call this method to bind the remote video stream to a video view and to set the rendering and mirror modes of the video view.
The application specifies the uid of the remote video in this method before the remote user joins the channel. If the remote uid is unknown to the application, set it after the application receives the onUserJoined callback. If the Video Recording function is enabled, the Video Recording Service joins the channel as a dummy client, causing other clients to also receive the onUserJoined callback. Do not bind the dummy client to the application view because the dummy client does not send any video streams. If your application does not recognize the dummy client, bind the remote user to the view when the SDK triggers the onFirstRemoteVideoDecoded callback. To unbind the remote user from the view, set the view in VideoCanvas to NULL. Once the remote user leaves the channel, the SDK unbinds the remote user.

Sets the stream type of the remote video.
Under limited network conditions, if the publisher has not disabled the dual-stream mode using enableDualStreamMode(false), the receiver can choose to receive either the high-quality video stream (the high resolution, and high bitrate video stream) or the low-video stream (the low resolution, and low bitrate video stream).
By default, users receive the high-quality video stream. Call this method if you want to switch to the low-video stream. This method allows the app to adjust the corresponding video stream type based on the size of the video window to reduce the bandwidth and resources.
The aspect ratio of the low-video stream is the same as the high-quality video stream. Once the resolution of the high-quality video stream is set, the system automatically sets the resolution, frame rate, and bitrate of the low-video stream.
The method result returns in the onApiCallExecuted callback.
