JoinOptions
The JoinOptions model defines how the application expects to join a conference.
For more information related to JoinOptions in terms of media preference, see MediaStreamConstraints.
Properties
audioBitrate
• audioBitrate: AudioBitrate
The preferred outgoing audio bitrate. Setting this property is available only while joining a non-Dolby Voice conference. Otherwise, the SDK triggers an error.
conferenceAccessToken
• Optional
conferenceAccessToken: string
The conference access token that is required to join a protected conference if the conference is created using the create REST API. If the conference is created using the create method, the token is managed by the SDK and is not visible to the application users. For more information, see the Enhanced Conference Access Control document.
constraints
• Optional
constraints: any
Sets the conference WebRTC constraints. By default, only audio is enabled: {audio: true, video: false}
unless a video has been started before joining a conference. If the constrains are not specified when a participants joins a conference, the SDK uses 720p (1280 x 720) resolution at 25fps to capture video.
Note: A video started before joining a conference will be added to the conference if video constraints are unfilled.
customVideoTrack
• Optional
customVideoTrack: MediaStreamTrack
A custom video track object to add to a conference. Defining this property causes ignoring video constraints defined in the constraints property. This property is available in SDK 3.7 and later.
customAudioTrack
• Optional
customAudioTrack: MediaStreamTrack
A custom audio track object to add to a conference. Defining this property causes ignoring audio constraints defined in the constraints property. This property is available in SDK 3.9 and later.
dvwc
• Optional
dvwc: boolean
Changes the audio codec used in Dolby Voice conferences in SDK 3.5 and later versions:
-
If set to true, the SDK uses the Dolby Voice Codec (DVC) on Chrome and Edge on desktop operating systems; on other browsers and mobile operating systems, the SDK uses Opus. If, for some reason, DVC cannot be used in a conference, the SDK uses Opus.
-
If set to false, the SDK uses Opus on all browsers and operating systems.
By default, this parameter is set to false. The following example shows how to create a Dolby Voice conference and join the conference using the Dolby Voice Codec:
// Create a Dolby Voice conference
const createOptions = {
alias: "wasm",
params: {
dolbyVoice: true
}
};
const conference = await VoxeetSDK.conference.create(createOptions);
// Join the Dolby Voice conference using Dolby Voice Codec
const joinOptions = {
dvwc: true
};
await VoxeetSDK.conference.join(conference, joinOptions);
For more information about the supported audio codecs, see the Dolby Voice document.
forwardingStrategy
• Optional
forwardingStrategy: VideoForwardingStrategy
Changes the video forwarding strategy for the local participant. This method is available only in SDK 3.6 and later.
leaveConferenceOnBeforeUnload
• Optional
leaveConferenceOnBeforeUnload: boolean
Allows handling the beforeunload event on the application level instead of on the SDK level. By default, the SDK listens to the beforeunload event and leaves a conference when this event is triggered. When leaveConferenceOnBeforeUnload is set to false, the SDK stops reacting on the beforeunload event, which allows customizing the beforeunload handling. When leaveConferenceOnBeforeUnload is set to false, the SDK does not react to events such as closing a tab to leave a conference and such events need to be also handled on the application level.
maxVideoForwarding
• Optional
maxVideoForwarding: number
Sets the maximum number of video streams that may be transmitted to the joining participant. The valid parameter's values are between 0 and 25 for desktop browsers and between 0 and 4 for mobile browsers. In the case of providing a value smaller than 0 or greater than the valid values, SDK triggers the VideoForwardingError. If the parameter value is not specified, the SDK automatically sets the maximum possible value: 25 for desktop browsers and 4 for mobile browsers.
This property is available in SDK 3.1 and later.
mixing
• Optional
mixing: MixingOptions
Allows joining conferences as Mixer.
preferRecvMono
• Optional
preferRecvMono: Boolean
Indicates whether a participant wants to receive mono sound. By default, participants receive stereo audio. This configuration is only applicable when using the Opus codec and is available in non-Dolby Voice and Dolby Voice conferences.
preferSendMono
• Optional
preferSendMono: Boolean
Indicates whether a participant wants to send mono sound to a conference. By default, when using the Opus codec, participants' audio is sent as mono. This configuration is only applicable when using the Opus codec and is available in non-Dolby Voice and Dolby Voice conferences.
simulcast
• Optional
simulcast: Boolean
Enables sending the Simulcast video streams to other conference participants.
spatialAudio
• Optional
spatialAudio: boolean
Enables spatial audio for the local participant who joins a Dolby Voice conference. By default, this parameter is set to false. When set to true in a conference that uses the individual spatial audio style, the application must place remote participants in a 3D space using the setSpatialPosition method.
Warning
In the individual spatial audio style, remote participants' audio is disabled until the participants are assigned to specific locations. We recommend calling setSpatialPosition from the participantUpdated event to ensure that all participants are assigned to specific positions.
videoFilter
• Optional
videoFilter: VideoFilter
The video filter that allows blurring or changing the local participant's background. The video filters are available only for the Dolby.io Communications SDK for Desktop users.
videoFilterOptions
• Optional
videoFilterOptions: VideoFilterOptions
Video filter options that include the image file for the staticImage filter and information about the video stream on which the video filter should be applied.
videoProcessor
• Optional
videoProcessor: VideoProcessor
The video processor that allows blurring or changing the local participant's background. This property is available only in SDK 3.7 and later.
