Enumeration Type Documentation

◆ VIDEO_RENDER_MODE

Video rendering mode.

Enumerator
RENDER_RAWDATA 

100: (Default) RawData.

REDNER_OPENGL_ES2 

101: OpenGLES 2.

RENDER_UNITY_LOW_LEVEL_INTERFACE 

102: Unity low level interface.

◆ ERROR_CODE

Error code, see more in Error Code.

Enumerator
ERROR_NOT_INIT_ENGINE 

-7: The SDK is not initialized before calling this method.

ERROR_OK 

0: No error occurs.

ERROR_INVALID_ARGUMENT 

-2: An invalid parameter is used. For example, the specific channel name includes illegal characters.

ERROR_NO_DEVICE_PLUGIN 

-100: No device is plugged.

◆ REMOTE_VIDEO_STREAM_TYPE

Remote video stream types.

Enumerator
REMOTE_VIDEO_STREAM_HIGH 

0: High-stream video.

REMOTE_VIDEO_STREAM_LOW 

1: Low-stream video.

◆ REMOTE_VIDEO_STATE

The state of the remote video.

Enumerator
REMOTE_VIDEO_STATE_STOPPED 

0: The remote video is in the default state, probably due to REMOTE_VIDEO_STATE_REASON_LOCAL_MUTED(3), REMOTE_VIDEO_STATE_REASON_REMOTE_MUTED(5), or REMOTE_VIDEO_STATE_REASON_REMOTE_OFFLINE(7).

REMOTE_VIDEO_STATE_STARTING 

1: The first remote video packet is received.

REMOTE_VIDEO_STATE_DECODING 

2: The remote video stream is decoded and plays normally, probably due to REMOTE_VIDEO_STATE_REASON_NETWORK_RECOVERY(2), REMOTE_VIDEO_STATE_REASON_LOCAL_UNMUTED(4), REMOTE_VIDEO_STATE_REASON_REMOTE_UNMUTED(6), or REMOTE_VIDEO_STATE_REASON_AUDIO_FALLBACK_RECOVERY(9).

REMOTE_VIDEO_STATE_FROZEN 

3: The remote video is frozen, probably due to REMOTE_VIDEO_STATE_REASON_NETWORK_CONGESTION(1) or REMOTE_VIDEO_STATE_REASON_AUDIO_FALLBACK(8).

REMOTE_VIDEO_STATE_FAILED 

4: The remote video fails to start, probably due to REMOTE_VIDEO_STATE_REASON_INTERNAL(0).

◆ AUDIO_MIXING_REASON_TYPE

The reason of audio mixing state change.

Enumerator
AUDIO_MIXING_REASON_CAN_NOT_OPEN 

701: The SDK cannot open the audio mixing file.

AUDIO_MIXING_REASON_TOO_FREQUENT_CALL 

702: The SDK opens the audio mixing file too frequently.

AUDIO_MIXING_REASON_INTERRUPTED_EOF 

703: The audio mixing file playback is interrupted.

AUDIO_MIXING_REASON_STARTED_BY_USER 

720: The audio mixing is started by user.

AUDIO_MIXING_REASON_ONE_LOOP_COMPLETED 

721: The audio mixing file is played once.

AUDIO_MIXING_REASON_START_NEW_LOOP 

722: The audio mixing file is playing in a new loop.

AUDIO_MIXING_REASON_ALL_LOOPS_COMPLETED 

723: The audio mixing file is all played out.

AUDIO_MIXING_REASON_STOPPED_BY_USER 

724: Playing of audio file is stopped by user.

AUDIO_MIXING_REASON_PAUSED_BY_USER 

725: Playing of audio file is paused by user.

AUDIO_MIXING_REASON_RESUMED_BY_USER 

726: Playing of audio file is resumed by user.

◆ USER_OFFLINE_REASON

Reasons for a user being offline.

Enumerator
QUIT 

0: The user quits the call.

DROPPED 

1: The SDK times out and the user drops offline because no data packet is received within a certain period of time. If the user quits the call and the message is not passed to the SDK (due to an unreliable channel), the SDK assumes the user dropped offline.

BECOME_AUDIENCE 

2: (Interactive live streaming only.) The client role switched from the host to the audience.

◆ LOG_FILTER

Output log filter level.

Enumerator
OFF 

0: Do not output any log information.

DEBUG 

0x80f: Output all log information. Set your log filter as debug if you want to get the most complete log file.

INFO 

0x0f: Output CRITICAL, ERROR, WARNING, and INFO level log information. We recommend setting your log filter as this level.

WARNING 

0x0e: Outputs CRITICAL, ERROR, and WARNING level log information.

ERROR 

0x0c: Outputs CRITICAL and ERROR level log information.

CRITICAL 

0x08: Outputs CRITICAL level log information.

◆ CHANNEL_PROFILE

The channel profile.

Enumerator
CHANNEL_PROFILE_COMMUNICATION 

0: (Default) Communication. This profile applies to scenarios such as an audio call or video call, where all users can publish and subscribe to streams.

CHANNEL_PROFILE_LIVE_BROADCASTING 

1: Live streaming. In this profile, uses have roles, namely, host and audience (default). A host both publishes and subscribes to streams, while an audience subscribes to streams only. This profile applies to scenarios such as a chat room or interactive video streaming.

CHANNEL_PROFILE_GAME 

2: Gaming. This profile uses a codec with a lower bitrate and consumes less power. Applies to the gaming scenario, where all game players can talk freely.

  @note Agora does not recommend using this setting.

◆ CLIENT_ROLE_TYPE

The role of a user in interactive live streaming.

Enumerator
CLIENT_ROLE_BROADCASTER 

1: Host. A host can both send and receive streams.

CLIENT_ROLE_AUDIENCE 

2: (Default) Audience, the default role. An audience member can only receive streams.

◆ AUDIO_RECORDING_QUALITY_TYPE

The audio recording quality, which is set in StartAudioRecording.

◆ CONNECTION_STATE_TYPE

Connection states.

Enumerator
CONNECTION_STATE_DISCONNECTED 

1: The SDK is disconnected from Agora's edge server.

  • This is the initial state before calling the JoinChannelByKey method.
  • The SDK also enters this state when the application calls the LeaveChannel method.
CONNECTION_STATE_CONNECTING 

2: The SDK is connecting to Agora's edge server.

  • When the application calls the JoinChannelByKey method, the SDK starts to establish a connection to the specified channel, triggers the OnConnectionStateChangedHandler callback, and switches to the CONNECTION_STATE_CONNECTING(2) state.
  • When the SDK successfully joins the channel, it triggers the OnConnectionStateChangedHandler callback and switches to the CONNECTION_STATE_CONNECTED(3) state.
  • After the SDK joins the channel and when it finishes initializing the media engine, the SDK triggers the OnJoinChannelSuccessHandler 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:

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 OnConnectionLostHandler callback, stays in the CONNECTION_STATE_RECONNECTING(4) 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 OnConnectionStateChangedHandler callback, switches to the CONNECTION_STATE_FAILED(5) 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 JoinChannelByKey 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 OnConnectionBannedHandler (deprecated) and OnConnectionStateChangedHandler callbacks.

  • The uid that you specify in the JoinChannelByKey method is different from the uid that you pass for generating the token.
CONNECTION_CHANGED_TOKEN_EXPIRED 

9: The connection failed since token is expired.

CONNECTION_CHANGED_REJECTED_BY_SERVER 

10: The connection is rejected by 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, JoinChannelByKey.
  • 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 connection changed to reconnecting since SDK has set a proxy server.

CONNECTION_CHANGED_RENEW_TOKEN 

12: When SDK is in connection failed, the renew token operation will make it connecting.

Occurs when a user joins a channel.

This callback notifies the application that a user joins a specified channel when the application calls the JoinChannelByKey method.

The channel name assignment is based on channelName specified in the JoinChannelByKey method.

If the uid is not specified in the JoinChannelByKey method, the server automatically assigns a uid.

Parameters
channelNameThe name of the channel that you join.
uidThe user ID of the user joining the channel.
elapsedTime elapsed (ms) from the user calling the JoinChannelByKey method until the SDK triggers this callback.

◆ OnLeaveChannelHandler()

delegate void agora_gaming_rtc.OnLeaveChannelHandler ( RtcStats  stats)

Occurs when a user leaves the channel.

This callback notifies the application that a user leaves the channel when the application calls the LeaveChannel method.

  • The SDK triggers the OnConnectionInterruptedHandler callback when it loses connection with the server for more than four seconds after it successfully joins the channel.
  • The SDK triggers the OnConnectionLostHandler callback when it loses connection with the server for more than 10 seconds, whether or not it joins the channel.

If the SDK fails to rejoin the channel 20 minutes after being disconnected from Agora's edge server, the SDK stops rejoining the channel.

◆ OnConnectionInterruptedHandler()

delegate void agora_gaming_rtc.OnConnectionInterruptedHandler ( )

Occurs when the connection between the SDK and the server is interrupted.

Deprecated:
Deprecated as of v2.3.2. Replaced by the OnConnectionStateChangedHandler callback.

The SDK triggers this callback when it loses connection with the server for more than four seconds after the connection is established.

After triggering this callback, the SDK tries reconnecting to the server. You can use this callback to implement pop-up reminders.

This callback is different from OnConnectionLostHandler:

  • The SDK triggers the OnConnectionInterruptedHandler callback when it loses connection with the server for more than four seconds after it successfully joins the channel.
  • The SDK triggers the OnConnectionLostHandler callback when it loses connection with the server for more than 10 seconds, whether or not it joins the channel.

If the SDK fails to rejoin the channel 20 minutes after being disconnected from Agora's edge server, the SDK stops rejoining the channel.

◆ OnRequestTokenHandler()

delegate void agora_gaming_rtc.OnRequestTokenHandler ( )

Occurs when the token expires.

After a token is specified by calling the JoinChannelByKey method, if the SDK losses connection with the Agora server due to network issues, the token may expire after a certain period of time and a new token may be required to reconnect to the server.

This callback notifies the app to generate a new token and call JoinChannelByKey to rejoin the channel with the new token.

◆ OnUserJoinedHandler()

delegate void agora_gaming_rtc.OnUserJoinedHandler ( uint  uid,
int  elapsed 
)

Occurs when a remote user (Communication)/ host (Live Broadcast) joins the channel.

  • Communication profile: This callback notifies the application that another user joins the channel. If other users are already in the channel, the SDK also reports to the application on the existing users.
  • Live-broadcast profile: This callback notifies the application that the host joins the channel. If other hosts are already in the channel, the SDK also reports to the application on the existing hosts. We recommend limiting the number of hosts to 17.

The SDK triggers this callback under one of the following circumstances:

  • A remote user/host joins the channel by calling the JoinChannelByKey method.
  • A remote user switches the user role to the host by calling the SetClientRole method after joining the channel.
  • A remote user/host rejoins the channel after a network interruption.
Note
In the Live-broadcast profile:
  • The host receives this callback when another host joins the channel.
  • The audience in the channel receives this callback when a new host joins the channel.
  • When a web application joins the channel, the SDK triggers this callback as long as the web application publishes streams.
Parameters
uidThe user ID of the user or host joining the channel.
elapsedTime delay (ms) from the local user calling the JoinChannelByKey method until the SDK triggers this callback.

◆ OnUserOfflineHandler()

delegate void agora_gaming_rtc.OnUserOfflineHandler ( uint  uid,
USER_OFFLINE_REASON  reason 
)

Occurs when a remote user (Communication)/host (Live Broadcast) leaves the channel.

Reasons why the user is offline:

  • Leave the channel: When the user/host leaves the channel, the user/host sends a goodbye message. When the message is received, the SDK assumes that the user/host leaves the channel.
  • Drop offline: When no data packet of the user or host is received for a certain period of time (20 seconds for the Communication profile, and more for the Live-broadcast profile), the SDK assumes that the user/host drops offline. Unreliable network connections may lead to false detections, so we recommend using the Agora RTM SDK for more reliable offline detection.
Parameters
uidThe user ID of the user leaving the channel or going offline.
reasonThe reason why the user is offline: USER_OFFLINE_REASON.

◆ OnVolumeIndicationHandler()

delegate void agora_gaming_rtc.OnVolumeIndicationHandler ( AudioVolumeInfo[]  speakers,
int  speakerNumber,
int  totalVolume 
)

Reports the volume information of users.

By default, this callback is disabled. You can enable it by calling EnableAudioVolumeIndication. Once this callback is enabled and users send streams in the channel, the SDK triggers the OnVolumeIndicationHandler callback at the time interval set in EnableAudioVolumeIndication.

The SDK triggers two independent OnVolumeIndicationHandler callbacks simultaneously, which separately report the volume information of the local user who sends a stream and the remote users (up to three) whose instantaneous volumes are the highest.

Note
After you enable this callback, calling MuteLocalAudioStream affects the SDK's behavior as follows:
  • If the local user calls MuteLocalAudioStream, the SDK stops triggering the local user's callback.
  • 20 seconds after a remote user whose volume is one of the three highest calls MuteLocalAudioStream, the remote users' callback excludes this remote user's information; 20 seconds after all remote users call MuteLocalAudioStream, the SDK stops triggering the remote users' callback.
Parameters
speakersThe volume information of users. See AudioVolumeInfo.

An empty speakers array in the callback indicates that no remote user is in the channel or sending a stream at the moment.

Parameters
speakerNumberTotal number of users.
  • In the local user's callback, when the local user sends a stream, speakerNumber = 1.
  • In the remote users' callback, the value ranges between 0 and 3. If the number of remote users who send streams is greater than or equal to three, speakerNumber = 3.
totalVolumeTotal volume after audio mixing. The value ranges between 0 (lowest volume) and 255 (highest volume).
  • In the local user's callback, totalVolume is the volume of the local user who sends a stream.
  • In the remote users' callback, totalVolume is the sum of the volume of all remote users (up to three) whose instantaneous volumes are the highest.

If the user calls StartAudioMixing, totalVolume is the sum of the voice volume and audio-mixing volume.

◆ OnLocalVoicePitchInHzHandler()

delegate void agora_gaming_rtc.OnLocalVoicePitchInHzHandler ( int  pitchInHz)

Reports the voice pitch of the local user.

Since
3.7.0

After the local audio capture is enabled and you call EnableLocalVoicePitchCallback, the SDK triggers this callback at the time interval set in EnableLocalVoicePitchCallback.

Note
After this callback is enabled, if the user disables the local audio capture, for example, by calling EnableLocalAudio(false), the SDK immediately stops sending the OnLocalVoicePitchInHzHandler callback.
Parameters
pitchInHzThe voice pitch (Hz) of the local user.

◆ OnUserMutedAudioHandler()

delegate void agora_gaming_rtc.OnUserMutedAudioHandler ( uint  uid,
bool  muted 
)

Occurs when a remote user's audio stream playback pauses/resumes.

Deprecated:
This method is deprecated from v3.0.1, use the OnRemoteAudioStateChangedHandler callback instead.

The SDK triggers this callback when the remote user stops or resumes sending the audio stream by calling the MuteLocalAudioStream method.

Note
This callback does not work properly when the number of users (in the COMMUNICATION profile) or hosts (in the LIVE_BROADCASTING profile) in the channel exceeds 17.
Parameters
uidThe user ID of the remote user.
mutedWhether the remote user's audio stream is muted/unmuted:
  • true: Muted.
  • false: Unmuted.

◆ OnSDKWarningHandler()

delegate void agora_gaming_rtc.OnSDKWarningHandler ( int  warn,
string  msg 
)

Reports a warning during SDK runtime.

In most cases, the application can ignore the warning reported by the SDK because the SDK can usually fix the issue and resume running. For example, when losing connection with the server, the SDK may report WARN_LOOKUP_CHANNEL_TIMEOUT(104) and automatically try to reconnect.

Parameters
warnThe warning code, see Warning Code.
msgThe warning message.

◆ OnSDKErrorHandler()

delegate void agora_gaming_rtc.OnSDKErrorHandler ( int  error,
string  msg 
)

Reports an error during SDK runtime.

In most cases, the SDK cannot fix the issue and resume running. The SDK requires the application to take action or informs the user about the issue.

For example, the SDK reports an ERR_START_CALL(1002) error when failing to initialize a call. The application informs the user that the call initialization failed and invokes the LeaveChannel method to leave the channel.

Parameters
errorThe error code, see Error Code.
msgThe error message.

◆ OnRtcStatsHandler()

delegate void agora_gaming_rtc.OnRtcStatsHandler ( RtcStats  stats)

Reports the statistics of the current call session once every two seconds.

This callback is triggered in either of the following scenarios:

  • The remote user joins the channel and sends the video stream.
  • The remote user stops sending the video stream and re-sends it after 15 seconds. Reasons for such an interruption include:
    • The remote user leaves the channel.
    • The remote user drops offline.
    • The remote user calls the MuteLocalVideoStream method to stop sending the video stream.
    • The remote user calls the DisableVideo method to disable video. The application can configure the user view settings in this callback.

CLIENT_ROLE_TYPE  newRole 
)

Occurs when the user role switches successfully in the interactive live streaming.

In the LIVE_BROADCASTING channel profile, when the local user successfully calls setClientRole to switch their user role after joining the channel, for example, from a host to an audience member or vice versa, the SDK triggers this callback to report the user role before and after the switch.

Parameters
oldRoleRole that the user switches from: CLIENT_ROLE_TYPE.
newRoleRole that the user switches to: CLIENT_ROLE_TYPE.

◆ OnUserMuteVideoHandler()

delegate void agora_gaming_rtc.OnUserMuteVideoHandler ( uint  uid,

Occurs when a remote user (Communication) or host (Live Broadcast) joins the channel.

  • Communication profile: This callback notifies the application that another user joins the channel. If other users are already in the channel, the SDK also reports to the application on the existing users.
  • Live-broadcast profile: This callback notifies the application that the host joins the channel. If other hosts are already in the channel, the SDK also reports to the application on the existing hosts. We recommend limiting the number of hosts to 17.

The SDK triggers this callback under one of the following circumstances:

  • A remote user or host joins the channel by calling the JoinChannel method.
  • A remote user switches the user role to the host by calling the SetClientRole method after joining the channel.
  • A remote user or host rejoins the channel after a network interruption.
Note
In the Live-broadcast profile:

)

Occurs when a remote user (Communication) or host (Live Broadcast) leaves the channel.

Reasons why the user is offline:

  • Leave the channel: When the user or host leaves the channel, the user or host sends a goodbye message. When the message is received, the SDK assumes that the user or host leaves the channel.
  • Drop offline: When no data packet of the user or host is received for a certain period of time (20 seconds for the Communication profile, and more for the Live-broadcast profile), the SDK assumes that the user or host drops offline. Unreliable network connections may lead to false detections, so we recommend using the Agora RTM SDK for more reliable offline detection.

◆ ChannelOnNetworkQualityHandler()

delegate void agora_gaming_rtc.ChannelOnNetworkQualityHandler ( string  channelId,
uint  uid,
int  txQuality,
int  rxQuality 
)

Reports the last mile network quality of each user in the channel once every two seconds.

Last mile refers to the connection between the local device and the Agora edge server. This callback reports once every two seconds the last mile network conditions of each user in the channel. If a channel includes multiple users, the SDK triggers this callback as many times.

Parameters
channelIdThe name of the channel that you join.
uidUser ID. The network quality of the user with this uid is reported. If uid is 0, the local network quality is reported.
txQualityUplink transmission quality rating of the user in terms of the transmission bitrate, packet loss rate, average RTT (Round-Trip Time), and jitter of the uplink network. txQuality is a quality rating helping you understand how well the current uplink network conditions can support the selected VideoEncoderConfiguration. For example, a 1000 Kbps uplink network may be adequate for video frames with a resolution of 640 × 480 and a frame rate of 15 fps in the Live-broadcast profile, but may be inadequate for resolutions higher than 1280 × 720. See QUALITY_TYPE.
rxQualityDownlink network quality rating of the user in terms of the packet loss rate, average RTT, and jitter of the downlink network. See QUALITY_TYPE.
