Meet Jit Si Jitsi Meet

JitsiMeetJS.init (options) - this method initialized Jitsi Meet API. The options parameter is JS object with the following properties: useIPv6 - boolean property disableAudioLevels - boolean property. The meet.jit.si instance is run by 8×8, the company that is also the main sponsor of the Jitsi open source project. After exiting a meeting on meet.jit.si you see this promotional message: Jitsi Meet is also available as a downloadable server version to set up your own Jitsi Meet instance.

Hi Folks,

As Jitsi Meet is being recommended as a tool to be used by non-tech savvy users in lieux of proprietary tools like Zoom or Google Meet, it is important that it meets safety requirements to avoid exposing users, and in particular children who are often asked to use these tools to meet with their teachers or their classmates, often unattended, as their parents are busy working. Jitsi Meet lets you stay in touch with all your teams, be they family, friends, or colleagues. Instant video conferences, efficiently adapting to your scale. Unlimited users: There are no artificial restrictions on the number of users or conference participants. Server power and bandwidth are the only limiting factors. No account needed. A simple way to schedule meetings using meet.jit.si, the latest hosted version of the opensource conference solution Jitsi Meet. Learn more at https://jitsi.org.

What Is Jitsi Meet

Amazing project :-). Quick question - I’m using Jitsi Meet, and would like to pass the name of the participant via a URL parameter so that they don’t need to set it themselves. Something like:

meet.jit.si/meeting-refererence?name=Alice

I’ve tried a few obvious parameter names, and taken a bit of a trawl through the code and docs, but can’t find any helpful reference. So - is it possible? Is there some page in the documentation that would list any URL parameters respected by Meet?

Jitsi Meet Installation

Thanks in advance for any assistance

You can use Jitsi Meet API to create Jitsi Meet video conferences with a custom GUI.

Installation

Jit

To embed Jitsi Meet API in your application you need to add Jitsi Meet API library

Now you can access Jitsi Meet API trough the JitsiMeetJS global object.

Getting Started

  1. The first thing you must do in order to use Jitsi Meet API is to initialize JitsiMeetJS object:
Meet jit si jitsi meet you
  1. Then you must create the connection object:
  1. Now we can attach some listeners to the connection object and establish the server connection:
  1. After you receive the CONNECTION_ESTABLISHED event you are to create the JitsiConference object andalso you may want to attach listeners for conference events (we are going to add handlers for remote track, conference joined, etc. ):
  1. You also may want to get your local tracks from the camera and microphone:

NOTE: Adding listeners and creating local streams are not mandatory steps.

  1. Then you are ready to create / join a conference :

After that step you are in the conference. Now you can continue with adding some code that will handle the events and manage the conference.

Components

Jitsi Meet API has the following components:

  • JitsiMeetJS

  • JitsiConnection

  • JitsiConference

  • JitsiTrack

  • JitsiTrackError

Usage

JaaS customers, please checkout this example: https://github.com/saghul/sandbox-html/tree/main/jaas-ljm. Live: https://bettercallsaghul.com/sandbox-html/jaas-ljm/

JitsiMeetJS

You can access the following methods and objects trough JitsiMeetJS object.

  • JitsiMeetJS.init(options) - this method initialized Jitsi Meet API.The options parameter is JS object with the following properties:

    • useIPv6 - boolean property
    • disableAudioLevels - boolean property. Enables/disables audio levels.
    • disableSimulcast - boolean property. Enables/disables simulcast.
    • enableWindowOnErrorHandler - boolean property (default false). Enables/disables attaching global onerror handler (window.onerror).
    • disableThirdPartyRequests - if true - callstats will be disabled and the callstats API won't be included.
    • enableAnalyticsLogging - boolean property (default false). Enables/disables analytics logging.
    • externalStorage - Object that implements the Storage interface. If specified this object will be used for storing data instead of localStorage.
    • callStatsCustomScriptUrl - (optional) custom url to access callstats client script
    • disableRtx - (optional) boolean property (default to false). Enables/disable the use of RTX.
    • disabledCodec - the mime type of the code that should not be negotiated on the peerconnection.
    • preferredCodec - the mime type of the codec that needs to be made the preferred codec for the connection.
    • useTurnUdp - boolean property (default false). Enables use of turn over udp for jvb. It is disabled because not very useful (if the client can use udp, it likely can connect to jvb directly over udp too; but it can be useful to still enable udp turn when an udp turn is known to be whitelisted on a network)
    • disableH264 - DEPRECATED. Use disabledCodec instead.
    • preferH264 - DEPRECATED. Use preferredCodec instead.
  • JitsiMeetJS.JitsiConnection - the JitsiConnection constructor. You can use that to create new server connection.

  • JitsiMeetJS.setLogLevel - changes the log level for the library. For example to have only error messages you should do:

  • JitsiMeetJS.createLocalTracks(options) - Creates the media tracks and returns them trough Promise object. If rejected, passes JitsiTrackError instance to catch block.

    • options - JS object with configuration options for the local media tracks. You can change the following properties there:
      1. devices - array with the devices - 'desktop', 'video' and 'audio' that will be passed to GUM. If that property is not set GUM will try to get all available devices.
      2. resolution - the prefered resolution for the local video.
      3. constraints - the prefered encoding properties for the created track (replaces 'resolution' in newer releases of browsers)
      4. cameraDeviceId - the deviceID for the video device that is going to be used
      5. micDeviceId - the deviceID for the audio device that is going to be used
      6. minFps - the minimum frame rate for the video stream (passed to GUM)
      7. maxFps - the maximum frame rate for the video stream (passed to GUM)
      8. desktopSharingFrameRate
        • min - Minimum fps
        • max - Maximum fps
      9. desktopSharingSourceDevice - The device id or label for a video input source that should be used for screensharing.
      10. facingMode - facing mode for a camera (possible values - 'user', 'environment')
      11. firePermissionPromptIsShownEvent - optional boolean parameter. If set to true, JitsiMediaDevicesEvents.PERMISSION_PROMPT_IS_SHOWN will be fired when browser shows gUM permission prompt.
      12. fireSlowPromiseEvent - optional boolean parameter. If set to true, JitsiMediaDevicesEvents.USER_MEDIA_SLOW_PROMISE_TIMEOUT will be fired when browser takes too long to resolve the gUM promise. This event is mutual exclusive with the above JitsiMediaDevicesEvents.PERMISSION_PROMPT_IS_SHOWN event
    • firePermissionPromptIsShownEvent - DEPRECATED. Use options.firePermissionPromptIsShownEvent instead
  • JitsiMeetJS.createTrackVADEmitter(localAudioDeviceId, sampleRate, vadProcessor) - Creates a TrackVADEmitter service that connects an audio track to a VAD (voice activity detection) processor in order to obtain VAD scores for individual PCM audio samples.

    • localAudioDeviceId - The target local audio device.
    • sampleRate - Sample rate at which the emitter will operate. Possible values 256, 512, 1024, 4096, 8192, 16384. Passing other values will default to closes neighbor, i.e. Providing a value of 4096 means that the emitter will process bundles of 4096 PCM samples at a time, higher values mean longer calls, lowers values mean more calls but shorter.
    • vadProcessor - VAD Processors that does the actual compute on a PCM sample.The processor needs to implement the following functions:
      • getSampleLength() - Returns the sample size accepted by calculateAudioFrameVAD.
      • getRequiredPCMFrequency() - Returns the PCM frequency at which the processor operates .i.e. (16KHz, 44.1 KHz etc.)
      • calculateAudioFrameVAD(pcmSample) - Process a 32 float pcm sample of getSampleLength size.
  • JitsiMeetJS.enumerateDevices(callback) - DEPRECATED. Use JitsiMeetJS.mediaDevices.enumerateDevices(callback) instead.

  • JitsiMeetJS.isDeviceChangeAvailable(deviceType) - DEPRECATED. Use JitsiMeetJS.mediaDevices.isDeviceChangeAvailable(deviceType) instead.

  • JitsiMeetJS.isDesktopSharingEnabled() - returns true if desktop sharing is supported and false otherwise. NOTE: that method can be used after JitsiMeetJS.init(options) is completed otherwise the result will be always null.

  • JitsiMeetJS.getActiveAudioDevice() - goes through all audio devices on the system and returns information about one that is active, i.e. has audio signal. Returns a Promise resolving to an Object with the following structure:

    • deviceId - string containing the device ID of the audio track found as active.
    • deviceLabel - string containing the label of the audio device.
  • JitsiMeetJS.getGlobalOnErrorHandler() - returns function that can be used to be attached to window.onerror and if options.enableWindowOnErrorHandler is enabled returns the function used by the lib. (function(message, source, lineno, colno, error)).

    • isDeviceListAvailable() - returns true if retrieving the device list is supported and false - otherwise
    • isDeviceChangeAvailable(deviceType) - returns true if changing the input (camera / microphone) or output (audio) device is supported and false if not. deviceType is a type of device to change. Undefined or 'input' stands for input devices, 'output' - for audio output devices.
    • enumerateDevices(callback) - returns list of the available devices as a parameter to the callback function. Every device is a MediaDeviceInfo object with the following properties:
      • label - the name of the device
      • kind - 'audioinput', 'videoinput' or 'audiooutput'
      • deviceId - the id of the device
      • groupId - group identifier, two devices have the same group identifier if they belong to the same physical device; for example a monitor with both a built-in camera and microphone

    • getAudioOutputDevice() - returns currently used audio output device id, ' stands for default device.
    • isDevicePermissionGranted(type) - returns a Promise which resolves to true if user granted permission to media devices. type - 'audio', 'video' or undefined. In case of undefined will check if both audio and video permissions were granted.
    • addEventListener(event, handler) - attaches an event handler.
    • removeEventListener(event, handler) - removes an event handler.
  • JitsiMeetJS.events - JS object that contains all events used by the API. You will need that JS object when you try to subscribe for connection or conference events.We have two event types - connection and conference. You can access the events with the following code JitsiMeetJS.events.<event_type>.<event_name>.For example if you want to use the conference event that is fired when somebody leave conference you can use the following code - JitsiMeetJS.events.conference.USER_LEFT.We support the following events:

  1. broadcastEndpointMessage(payload) - Sends broadcast message via the datachannels.
    • payload - JSON object - the payload of the message.

Throws NetworkError or InvalidStateError or Error if the operation fails.

  1. replaceTrack - replaces the track currently being used as the sender's source with a new MediaStreamTrack. The new track must be of the same media kind (audio, video, etc) and switching the track should not require negotiation. replaceTrack(oldTrack, newTrack)

Throws NetworkError or InvalidStateError or Error if the operation fails.

How Does Jitsi Meet Work

  1. setReceiverConstraints - set the constraints for the video that is requested from the bridge. This single message should be used in lieu of setLastN, setReceiverVideoConstraint and selectParticipants methods. These constraints are applicable to bridge connection only. More information about the signaling message format and how the Jitsi Videobridge allocates bandwidth can be found here.

    • videoConstraints - Object that specifies the constraints in the following format.
  2. setReceiverVideoConstraint(resolution) - set the desired resolution to get from JVB (180, 360, 720, 1080, etc).You should use that method if you are using simulcast.

  3. setSenderVideoConstraint(resolution) - set the desired resolution to send to JVB or the peer (180, 360, 720).

  4. isHidden - checks if local user has joined as a 'hidden' user. This is a specialized role used for integrations.

  5. setLocalParticipantProperty(propertyKey, propertyValue) - used to set a custom propery to the local participant('fullName': 'Full Name', favoriteColor: 'red', 'userId': 234). Also this can be used to modify an already set custom property.

    • propertyKey - string - custom property name
    • propertyValue - string - custom property value
  6. getParticipants() - Retrieves an array of all participants in this conference.

  7. revokeOwner(participantId) - Revokes owner's rights to the participant. The particiapnt that invokes the function should have same or more rights than the targeted participant. This rights check is done at the XMPP server level.

JitsiTrack

The object represents single track - video or audio. They can be remote tracks ( from the other participants in the call) or local tracks (from the devices of the local participant).We have the following methods for controling the tracks:

  1. getType() - returns string with the type of the track( 'video' for the video tracks and 'audio' for the audio tracks)

  2. mute() - mutes the track. Returns Promise.

    Note: This method is implemented only for the local tracks.

  3. unmute() - unmutes the track. Returns Promise.

    Note: This method is implemented only for the local tracks.

  4. isMuted() - check if track is muted

  5. attach(container) - attaches the track to the given container.

  6. detach(container) - removes the track from the container.

  7. dispose() - disposes the track. If the track is added to a conference the track will be removed. Returns Promise.

    Note: This method is implemented only for the local tracks.

  8. getId() - returns unique string for the track.

  9. getParticipantId() - returns id(string) of the track owner

    Note: This method is implemented only for the remote tracks.

  10. setAudioOutput(audioOutputDeviceId) - sets new audio output device for track's DOM elements. Video tracks are ignored.

  11. getDeviceId() - returns device ID associated with track (for local tracks only)

  12. isEnded() - returns true if track is ended

  13. setEffect(effect) - Applies the effect by swapping out the existing MediaStream on the JitsiTrack with the new

    MediaStream which has the desired effect. 'undefined' is passed to this function for removing the effect and for

    restoring the original MediaStream on the JitsiTrack.

    The following methods have to be defined for the effect instance.

    startEffect() - Starts the effect and returns a new MediaStream that is to be swapped with the existing one.

    stopEffect() - Stops the effect.

    isEnabled() - Checks if the local track supports the effect.

    Note: This method is implemented only for the local tracks.

JitsiTrackError

The object represents error that happened to a JitsiTrack. Is inherited from JavaScript base Error object,so 'name', 'message' and 'stack' properties are available. For GUM-related errors,exposes additional 'gum' property, which is an object with following properties:

How Do I Use Jitsi Meet

  • error - original GUM error
  • constraints - GUM constraints object used for the call
  • devices - array of devices requested in GUM call (possible values - 'audio', 'video', 'screen', 'desktop', 'audiooutput')
