0: No error.

1: General error with no classified reason.

2: Invalid parameter. For example, the specific channel name contains illegal characters.

3: The SDK module is not ready. Agora recommends the following methods to solve this error:

• Check the audio device.
• Check the completeness of the app.
• Re-initialize the SDK.

0: Everything is normal.

1: Errors from the Agora Native SDK. See more Error Codes.

2: Failure to join the channel.

3: Failure to create a process.

4: Invalid parameters of the video profile of the mixed video. See Video Profile Table to set the mixResolution parameter.

5: Null pointer.

6: Invalid parameters of the proxy server.

0x8: Error in polling.

0x10: Polling hangs up.

0x20: Invalid polling request.

0: The initialization fails.

1: The AgoraCoreService process receives the SIGINT signal.

2: The recording application automatically leaves the channel and stops recording as there is no user in the channel.

3: The AgoraCoreService process receives the SIGTERM signal.

4: The recording application calls the leaveChannel method to leave the channel.

103: No channel resources are available. Maybe because the server cannot allocate any channel resource.

104: A timeout when looking up the channel. When a user joins a channel, the SDK looks up the specified channel. This warning usually occurs when the network conditions are too poor to connect to the server.

105: The server rejected the request to look up the channel. The server cannot process this request or the request is illegal.

106: A timeout occurred when opening the channel. Once the specific channel is found, the SDK opens the channel. This warning usually occurs when the network conditions are too poor to connect to the server.

107: The server rejected the request to open the channel. The server cannot process this request or the request is illegal.

108: An abnormal error occurs. The SDK would resume the recording.

0: (Default) Communication mode. This is used in one-on-one or group calls, where all users in the channel can talk freely.

1: Live broadcast mode. The host sends and receives voice/video, while the audience only receives voice/video. Host and audience roles can be set by calling setClientRole.

0: The user has quit the call.

1: The SDK timed out and the user dropped offline because it has not received any data packet for a period of time. If a user quits the call and the message is not passed to the SDK (due to an unreliable channel), the SDK assumes the user has dropped offline.

2: The client role has changed from the host to the audience. The option is only valid when you set the channel profile as live broadcast when calling joinChannel.

0: (Default) High stream.

1: Low stream.

0: Default video format.

1: Video frame in H.264 format.

2: Video frame in YUV format.

3: Video frame in JPEG format.
