Caller

Initiate a Call

Use SDK default parameters unless otherwise required.

• Camera: Front-facing camera by default.
• Video parameters: 480 x 640, 30 FPS by default.

You may also specify camera and video parameters before each call. See setVideoConfig.

When rejecting or ending a call, the SDK handles it automatically and notifies the peer about the reason.

Default Call Method

Call RCCallEngine.startCall to initiate a one-to-one audio/video call.

Note

This method activates the default camera device (typically front-facing).

• Parameters:

  Parameter	Type	Required	Description
  targetId	String	Yes	Target UserId
  mediaType	RCCallMediaType	Yes	Call media type
  extra	String	No	Extra info, delivered to the peer via RCCallSession.extra

• Example:

  /// Callee User ID
  String targetId = 'UserB';
  /// Call media type
  RCCallMediaType mediaType = RCCallMediaType.audio_video;
  /// Extra info
  String extra = '';
  engine?.startCall(targetId, mediaType, extra);

Initiate Call with Specified Camera

Specify camera and video parameters before initiating a call.

• Example:

  RCCallVideoConfig videoConfig = RCCallVideoConfig.create(
    /// Use rear camera
    defaultCamera: RCCallCamera.back,
  );
  /// Configure video parameters
  engine?.setVideoConfig(videoConfig);
  /// Callee User ID
  String targetId = 'UserB';
  /// Call media type
  RCCallMediaType mediaType = RCCallMediaType.audio_video;
  /// Extra info
  String extra = '';
  engine?.startCall(targetId, mediaType, extra);

End Call

Call RCCallEngine.hangup to end or reject a call. The SDK automatically notifies the peer about the reason.

• Example:

  engine?.hangup();
