Agora supports publishing multiple audio streams and one video stream at the same time and in the same RtcConnection. For example, publishMicrophoneTrack, publishCustomAudioTrack, and publishMediaPlayerAudioTrack can be set as true at the same time, but only one of publishCameraTrack, publishScreenCaptureVideo, publishScreenTrack, publishCustomVideoTrack, or publishEncodedVideoTrack can be set as true.

Attention: Agora recommends that you set member parameter values yourself according to your business scenario, otherwise the SDK will automatically assign values to member parameters.

Attributes

enableAudioRecordingOrPlayout

Whether to enable audio capturing or playback:

true: Enable audio capturing or playback.
false: Do not enable audio capturing or playback.

Note: If you need to publish the audio streams captured by your microphone, ensure this parameter is set as true.

publishMediaPlayerId

The ID of the media player to be published. The default value is 0.

clientRoleType

The user role. See CLIENT_ROLE_TYPE.

Note: If you set the user role as an audience member, you cannot publish audio and video streams in the channel. If you want to publish media streams in a channel during live streaming, ensure you set the user role as broadcaster.

audienceLatencyLevel

The latency level of an audience member in interactive live streaming. See AUDIENCE_LATENCY_LEVEL_TYPE.

defaultVideoStreamType

The default video-stream type. See VIDEO_STREAM_TYPE.

channelProfile

The channel profile. See CHANNEL_PROFILE_TYPE.

audioDelayMs

Delay (in milliseconds) for sending audio frames. You can use this parameter to set the delay of the audio frames that need to be sent, to ensure audio and video synchronization.

To switch off the delay, set the value to 0.

token

(Optional) The token generated on your server for authentication. See .

Attention:

This parameter takes effect only when calling UpdateChannelMediaOptions or UpdateChannelMediaOptionsEx.
Ensure that the App ID, channel name, and user name used for creating the token are the same as those used by the Initialize method for initializing the RTC engine, and those used by the JoinChannel [2/2] and JoinChannelEx methods for joining the channel.

publishRhythmPlayerTrack

Whether to publish the sound of a metronome to remote users:

true: Publish processed audio frames. Both the local user and remote users can hear the metronome.
false: Do not publish the sound of the metronome. Only the local user can hear the metronome.

isInteractiveAudience

Whether to enable interactive mode:

true: Enable interactive mode. Once this mode is enabled and the user role is set as audience, the user can receive remote video streams with low latency.
false:Do not enable interactive mode. If this mode is disabled, the user receives the remote video streams in default settings.

Attention:

This parameter only applies to co-streaming scenarios. The cohosts need to call the JoinChannelEx method to join the other host's channel as an audience member, and set isInteractiveAudience to true.
This parameter takes effect only when the user role is CLIENT_ROLE_AUDIENCE.

customVideoTrackId

The video track ID returned by calling the CreateCustomVideoTrack method. The default value is 0.

isAudioFilterable

Whether the audio stream being published is filtered according to the volume algorithm:

true: The audio stream is filtered. If the audio stream filter is not enabled, this setting does not takes effect.
false: The audio stream is not filtered.

Attention: If you need to enable this function, contact support@agora.io.
