Initial Call Configuration

There are two ways to configure the initial call setup:

• Using the Stream Dashboard to setup the initial configuration per call type
• Passing the initial configuration in by CallConnectOptions parameter

Stream Dashboard

You can configure the initial call setup using the Stream Dashboard. This is useful when you want to set up the initial configuration for a specific call type. Find the call type you want to configure on the list of call types: https://dashboard.getstream.io/app/{YOUR-APP-ID}/video/call-types. Then under Video, Audio and Advanced settings sections you can set things like:

• Turn camera on/off by default
• Turn microphone on/off by default
• Set default camera facing
• Set default audio output device

Default Device Selection Logic

The Stream Dashboard settings control device selection through a priority-based system:

Audio Output Priority:

1. External devices (headphones, Bluetooth) - Always preferred when available

2. Speaker - Used when video camera is on, speaker setting is enabled, or explicitly set as default device

3. Earpiece - Fallback for mobile devices

Audio Input:

• Matches the output device when possible (e.g., Bluetooth headset for both input/output)
• Uses first available microphone as fallback

Video Input:

• Selects camera based on Dashboard camera_facing setting (front/back/external)
• Chooses external camera when multiple devices available
• Defaults to any available camera if preferred facing unavailable

CallConnectOptions parameter

​ Using the CallConnectOptions class you can configure the initial call setup programmatically. It provides the following options:

• Enabling or disabling the camera
• Enabling or disabling the microphone
• Enabling or disabling the screen sharing
• Setting the camera facing mode
• Setting the audio output device
• Setting the audio input device

You can provide this class as a parameter when joining a call:

  final call = client.makeCall(callType: StreamCallType.defaultType(), id: '345');
  await call.join(connectOptions: connectOptions);

Or by passing it to the StreamCallContainer widget

StreamCallContainer(
          call: widget.call,
          callConnectOptions: connectOptions,
          ...
);

You can access current options by calling call.connectOptions on the Call object.

  final call = client.makeCall(callType: StreamCallType.defaultType(), id: '345');
  await call.getOrCreate();
  final callOptions = call.connectOptions;
