Gets the SDK version.
| int agora_gaming_rtc.IRtcEngine.SetChannelProfile | ( | CHANNEL_PROFILE | profile | ) |
Sets the channel profile of the Agora IRtcEngine.
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 a video broadcast.
| profile | The channel profile of the Agora IRtcEngine. See CHANNEL_PROFILE. |
| int agora_gaming_rtc.IRtcEngine.SetClientRole | ( | CLIENT_ROLE_TYPE | role | ) |
Sets the role of the user, such as a host or an audience (default), before joining a channel in the interactive live streaming.
This method can be used to switch the user role in the interactive live streaming after the user joins a channel.
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:
MuteLocalAudioStream and MuteLocalVideoStream to change the publishing state.OnClientRoleChangedHandler or OnClientRoleChangeFailedHandler on the local client.OnUserJoinedHandler or OnUserOfflineHandler(BECOME_AUDIENCE) on the remote client.| role | Sets the role of the user. See CLIENT_ROLE_TYPE. |
| int agora_gaming_rtc.IRtcEngine.SetLogFilter | ( | LOG_FILTER | filter | ) |
Sets the output log level of the SDK.
logConfig in the GetEngine method instead.You can use one or a combination of the log filter levels. The log level follows the sequence of OFF, CRITICAL, ERROR, WARNING, INFO, and DEBUG. Choose a level to see the logs preceding that level.
For example, when you set the log level to WARNING, you can see the logs within levels CRITICAL, ERROR, and WARNING.
| filter | Sets the log filter level. See LOG_FILTER. |
| int agora_gaming_rtc.IRtcEngine.SetLogFile | ( | string | filePath | ) |
Sets the log files that the SDK outputs.
logConfig in the GetEngine method instead.By default, the SDK outputs five log files, agorasdk.log, agorasdk_1.log, agorasdk_2.log, agorasdk_3.log, agorasdk_4.log, each with a default size of 1024 KB. These log files are encoded in UTF-8. The SDK writes the latest logs in agorasdk.log. When agorasdk.log is full, the SDK deletes the log file with the earliest modification time among the other four, renames agorasdk.log to the name of the deleted log file, and create a new agorasdk.log to record latest logs.
| filePath | The absolute path of log files. The default file path is C: \Users\<user_name>\AppData\Local\Agora\<process_name>\agorasdk.log. Ensure that the directory for the log files exists and is writable. You can use this parameter to rename the log files. |
| int agora_gaming_rtc.IRtcEngine.SetDefaultEngineSettings | ( | ) |
| int agora_gaming_rtc.IRtcEngine.JoinChannel | ( | string | channelName, |
| string | info = "", |
||
| uint | uid = 0 |
||
| ) |
Allows a user to join a channel.
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:
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.| channelName | The unique channel name for the Agora RTC session in the string format smaller than 64 bytes. Supported characters:
|
| info | (Optional) 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 OnJoinChannelSuccessHandler callback. Your application must record and maintain the returned uid since the SDK does not do so. |
ERR_INVALID_ARGUMENT(-2)ERR_NOT_READY(-3)ERR_REFUSED(-5) | int agora_gaming_rtc.IRtcEngine.JoinChannelByKey | ( | string | channelKey, |
| string | channelName, | ||
| string | info = "", |
||
| uint | uid = 0 |
||
| ) |
Allows a user to join a channel with token.
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 JoinChannelByKey method call triggers the following callbacks:
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 OnReJoinChannelSuccessHandler callback on the local client.
Once the user joins the 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 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.| channelKey | The token generated by the application server. In most circumstances, a static App ID suffices. For added security, use a Channel Key.
|
| channelName | The unique channel name for the Agora RTC session in the string format smaller than 64 bytes. Supported characters:
|
| info | (Optional) 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 OnJoinChannelSuccessHandler callback. Your application must record and maintain the returned uid since the SDK does not do so. |
AgoraChannel object with the same channel name.AgoraChannel object. | int agora_gaming_rtc.IRtcEngine.RenewToken | ( | string | token | ) |
Gets a new token when the current token expires after a period of time.
The token expires after a period of time once the token schema is enabled when:
The application should call this method to get the new token. Failure to do so will result in the SDK disconnecting from the server.
| token | The new token. |
| int agora_gaming_rtc.IRtcEngine.LeaveChannel | ( | ) |
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 destroys 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 OnLeaveChannelHandler callback.
A successful LeaveChannel method call triggers the following callbacks:
OnLeaveChannelHandlerLeaveChannel method, the LeaveChannel process interrupts, and the OnLeaveChannelHandler callback is not triggered.LeaveChannel method during a CDN live streaming, the SDK triggers the RemovePublishStreamUrl method.| void agora_gaming_rtc.IRtcEngine.Pause | ( | ) |

| int agora_gaming_rtc.IRtcEngine.SetRemoteVideoStreamType | ( | uint | uid, |
| REMOTE_VIDEO_STREAM_TYPE | streamType | ||
| ) |
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 OnApiExecutedHandler callback.

Destroys the IRtcEngine instance and releases all resources used by the Agora RTC SDK.
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 Destroy 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 GetEngine to Initialize a new IRtcEngine instance.
Destroy is a synchronous method and the app cannot move on to another task until the execution completes, Agora suggests calling this method in a sub-thread to avoid congestion in the main thread. Besides, you cannot call Destroy in any method or callback of the SDK. Otherwise, the SDK cannot release the resources occupied by the IRtcEngine instance until the callbacks return results, which may result in a deadlock.IRtcEngine instance after destroying the current one, ensure that you wait till the destroy method completes executing.
