VideoSDK Class Methods - Flutter

createRoom()

• This method is provided by SDK to build instance of VideoSDK Room based on given configuration.

Parameters

• roomId

  • type: String
  • REQUIRED
  • Id of the Room to be created.

• token

  • type: String
  • REQUIRED
  • Sets AuthToken, which is used for authentication purposes.

• displayName

  • type: String
  • REQUIRED
  • Sets name of the LocalParticipant to be displayed.

• notification

  • type: [NotificationInfo]
  • OPTIONAL
  • Sets configuration for the notification, that will be shown, while screen-sharing.

• micEnabled

  • type: bool
  • OPTIONAL
  • Whether mic of the participant will be on, while joining the room. If it is set to false, then mic of that participant will be disabled by default, but can be enabled or disabled later.
  • Default value of micEnabled is true.

• camEnabled

  • type: bool
  • OPTIONAL
  • Whether camera of the participant will be on, while joining the room. If it is set to false, then camera of that participant will be disabled by default, but can be enabled or disabled
  • Default value of camEnabled is true.

• multiStream

  • type: bool
  • OPTIONAL
  • Default value is true.
  • It will specify if the stream should send multiple resolution layers or single resolution.

• participantId

  • type: String
  • OPTIONAL
  • Unique Id of the participant. If not passed then SDK will create an Id by itself and will use that id.

• maxResolution

  • type: String
  • OPTIONAL
  • Sets the maximum upload resolution of that participant's camera video stream.

• defaultCameraIndex

  • type: int
  • OPTIONAL
  • Sets camera, which will be used by default, while joining the VideoSDK Room. Index of MediaDevices will be used to set default camera. You can also change camera later.
  • Default value of defaultCameraIndex is 0.

• customCameraVideoTrack

  • type: CustomTrack
  • OPTIONAL
  • Set the initial custom video track using different encoding parameters, camera facing mode, and optimization mode.

• customMicrophoneAudioTrack

  • type: CustomTrack
  • OPTIONAL
  • Set the initial custom audio track using different encoding parameters and optimization mode.

• mode

  • type: Mode
  • OPTIONAL
  • Set the participant mode i.e. SEND_AND_RECV or SIGNALLING_ONLY.
  • Default value is SEND_AND_RECV.

Returns

• Room

Example

CustomTrack videoTrack = await VideoSDK.createCameraVideoTrack(
  encoderConfig: CustomVideoTrackConfig.h1440p_w1920p,
  multiStream: false,
);

//Creating Custom Audio Track
CustomTrack audioTrack = await VideoSDK.createMicrophoneAudioTrack(
    encoderConfig: CustomAudioTrackConfig.high_quality);

// Create VideoSDK Room
Room room = VideoSDK.createRoom(
  roomId: "<ROOM-ID>",
  token: "<TOKEN>",
  displayName: "<DISPLAY-NAME>",
  micEnabled: false,
  camEnabled: false,
  maxResolution: 'hd',
  multiStream: false,
  defaultCameraIndex: 1, // Front Camera
  customCameraVideoTrack: videoTrack, // custom video track :: optional
  customMicrophoneAudioTrack: audioTrack, // custom audio track :: optional
  notification: const NotificationInfo(
    title: "Video SDK",
    message: "Video SDK is sharing screen in the room",
    icon: "notification_share",
  ),
);

loadMediaDevices()

• This method is used to load or refresh MediaDevices i.e. Audio Devices and Video Devices.

Returns

• Future<Map<MediaDeviceType, List<MediaDeviceInfo>>>

Example

Map<MediaDeviceType, List<MediaDeviceInfo>> mediaDevices = await VideoSDK.loadMediaDevices();

createCameraVideoTrack

• You can create a Video Track using createCameraVideoTrack() method of VideoSDK class.
• This method can be used to create video track using different encoding parameters, camera facing mode, and optimization mode.

Parameters

• cameraId:

  • type: String
  • required: false
  • It will be the id of the camera from which the video should be captured.

• encoderConfig:

  • type: CustomVideoTrackConfig
  • required: false
  • default: h360p_w640p
  • Allowed values : h90p_w160p | h180p_w320p | h216p_w384p | h360p_w640p | h540p_w960p | h720p_w1280p | h1080p_w1920p | h1440p_w2560p | h2160p_w3840p | h120p_w160p | h180p_w240p | h240p_w320p | h360p_w480p | h480p_w640p | h540p_w720p | h720p_w960p | h1080p_w1440p | h1440p_w1920p
  • It will be the encoderConfigs you can want to use for the Video Track.

note

Above mentioned encoder configurations are valid for both, landscape as well as portrait mode.

• facingMode:

  • type: String
  • required: false
  • Allowed values : user | environment
  • It will specify whether to use front or back camera for the video track.

• multiStream

  • type: boolean
  • required: false
  • default: true
  • It will specify if the stream should send multiple resolution layers or single resolution layer.
  info

  • For meetings with fewer than or equal to four participants, setting multiStream:false is regarded as best practice.
  • This parameter is only available from v1.0.9.

Returns

• Future<CustomTrack>

Example

CustomTrack videoTrack = await VideoSDK.createCameraVideoTrack(
      encoderConfig: CustomVideoTrackConfig.h1440p_w1920p,
      multiStream: false,
      facingMode:"user",
    );
