When a stream is added to a session, the Session object dispatches a\n * streamCreatedEvent. When a stream is destroyed, the Session object dispatches a\n * streamDestroyed event. The StreamEvent object, which defines these event objects,\n * has a stream property, which is an array of Stream object. For details and a code\n * example, see {@link StreamEvent}.
When a connection to a session is made, the Session object dispatches a\n * sessionConnected event, defined by the SessionConnectEvent object. The\n * SessionConnectEvent object has a streams property, which is an array of Stream\n * objects pertaining to the streams in the session at that time. For details and a code example,\n * see {@link SessionConnectEvent}.

This value is calculated in milliseconds.

This property is only set if\n * the publisher of the stream specifies a frame rate when calling the\n * OT.initPublisher() method; otherwise, this property is undefined.\n *\n * @property {Boolean} hasAudio Whether the stream has audio. This property can change if the\n * publisher turns on or off audio (by calling\n * Publisher.publishAudio()). When this occurs, the\n * {@link Session} object dispatches a streamPropertyChanged event (see\n * {@link StreamPropertyChangedEvent}).\n *\n * @property {Boolean} hasVideo Whether the stream has video. This property can change if the\n * publisher turns on or off video (by calling\n * Publisher.publishVideo()). When this occurs, the\n * {@link Session} object dispatches a streamPropertyChanged event (see\n * {@link StreamPropertyChangedEvent}).\n *\n * @property {String} name The name of the stream. Publishers can specify a name when publishing\n * a stream (using the publish() method of the publisher's Session object).\n *\n * @property {String} streamId The unique ID of the stream.\n *\n * @property {Object} videoDimensions This object has two properties: width and\n * height. Both are numbers. The width property is the width of the\n * encoded stream; the height property is the height of the encoded stream. (These\n * are independent of the actual width of Publisher and Subscriber objects corresponding to the\n * stream.) This property can change if a stream published from a mobile device resizes, based on\n * a change in the device orientation. When the video dimensions change,\n * the {@link Session} object dispatches a streamPropertyChanged event\n * (see {@link StreamPropertyChangedEvent}).\n *\n * @property {String} videoType The type of video — either \"camera\",\n * \"screen\", or \"custom\".\n * A \"screen\" video uses screen sharing on the publisher\n * as the video source; for other videos, this property is set to \"camera\".\n * A \"custom\" video uses a VideoTrack element as the video source on the publisher.\n * (See the videoSource property of the options parameter passed\n * into the OT.initPublisher() method.)\n * The videoType is undefined when a stream is voice-only\n * (see the Voice-only guide).\n * This property can change if a stream published from a mobile device changes from a\n * camera to a screen-sharing video type.

These controls include the name\n * display, the audio level indicator, and the microphone control button. You can turn off all user\n * interface controls by setting this property to false. You can control the display\n * of individual user interface controls by leaving this property set to true (the\n * default) and setting individual properties of the style property.\n * style object includes\n * the following properties:\n * audioLevelDisplayMode (String) — How to display the audio level\n * indicator. Possible values are: \"auto\" (the indicator is displayed when the\n * video is disabled), \"off\" (the indicator is not displayed), and\n * \"on\" (the indicator is always displayed).archiveStatusDisplayMode (String) — How to display the archive status\n * indicator. Possible values are: \"auto\" (the indicator is displayed when the\n * session is being recorded), \"off\" (the indicator is not displayed). If you\n * disable the archive status display indicator, you can display your own user interface\n * notifications based on the archiveStarted and archiveStopped\n * events dispatched by the Session object.backgroundImageURI (String) — A URI for an image to display as\n * the background image when a video is not displayed. (A video may not be displayed if\n * you call publishVideo(false) on the Publisher object). You can pass an http\n * or https URI to a PNG, JPEG, or non-animated GIF file location. You can also use the\n * data URI scheme (instead of http or https) and pass in base-64-encrypted\n * PNG data, such as that obtained from the\n * Publisher.getImgData() method. (For example,\n * you could set the property to a value returned by calling getImgData() on\n * a previous Publisher object.) If the URL or the image data is invalid, the property\n * is ignored (the attempt to set the image fails silently).buttonDisplayMode (String) — How to display the microphone controls\n * Possible values are: \"auto\" (controls are displayed when the stream is first\n * displayed and when the user mouses over the display), \"off\" (controls are not\n * displayed), and \"on\" (controls are always displayed).nameDisplayMode (String) — Whether to display the stream name.\n * Possible values are: \"auto\" (the name is displayed when the stream is first\n * displayed and when the user mouses over the display), \"off\" (the name is not\n * displayed), and \"on\" (the name is always displayed).\n *
\"\" — No hint is provided (the default).\n * \"motion\" — The track should be treated as if it contains video\n * where motion is important. For example, you may use this setting for a screen-sharing\n * stream that contains video.\n * \"detail\" — The track should be treated as if video details\n * are extra important. For example, you may use this setting for a screen-sharing\n * stream that contains text content, painting, or line art.\n * \"text\" — The track should be treated as if text details are\n * extra important. For example, you may use this setting for a screen-sharing\n * stream that contains text content.\n * \n * With the "text" and "detailed" content hints, the browser attempts to maintain\n * high resolution, even if it must reduce the video frame rate. For the "motion" content hint,\n * the browser reduces resolution to prevent the frame rate from stalling.\n *
\n *\n * You can read more about these options in the\n * W3C Working Draft.\n * You may want to set the video content hint to optimize performance for screen-sharing\n * videos. For example, you can set it to \"text\" when sharing a screen that contains\n * a lot of text (such as a slideshow).\n *
\n * Chrome 60+, Safari 12.1+, Edge 79+, and Opera 47+ support video content hints.\n *
\n *\n * Also see the Publisher.setVideoContentHint() method\n * and the developer\n * guide topic on this feature.\n *
\n *\n * Background blur filter — Set the type property of the object to\n * \"backgroundBlur\".\n *
\n * A background blur filter object includes an additional blurStrength property, which\n * defines the blur radius and is optional. Set this to either \"low\" or\n * \"high\" (the default).\n *
\n * Background replacement filter — Set the type property of the object to\n * \"backgroundReplacement\".\n *
\n * A background replacement filter object includes an additional backgroundImgUrl\n * property, which defines the URL of the background image to use. Also accepted are image BLOBs\n * (a Base64-encoded string of image data).\n * The following image formats are supported: BMP, PNG, JPEG, and GIF.\n *
\n * This is a beta feature.\n *
\n * You can change the video filter by calling the\n * Publisher.applyVideoFilter() method.\n * You can remove the video filter by calling the\n * Publisher.clearVideoFilter() method.\n *
OT.initPublisher() fails with an\n * error (error code 1500, \"Unable to Publish\") passed to the completion handler function.\n * \n * If you set this property to null or false, the browser does not\n * request access to the camera, and no video is published. In a voice-only call, set this\n * property to null or false for each Publisher.\n *
\n * To publish a screen-sharing stream, set this property to \"screen\".\n * In older browser versions, you could also pass in \"application\" or\n * \"window\" to specify a type of screen-sharing source. However, in current\n * browsers that support screen sharing, passing in any of these values results in\n * the same behavior — the browser displays a dialog box in which the end user\n * selects the screen-sharing source (which can be the entire screen or a specific window).\n * In Electron, screen sharing captures the entire screen, without prompting\n * the user for permission. For screen-sharing streams, the following are\n * default values for other properties: audioFallbackEnabled == false,\n * maxResolution == {width: 1920, height: 1920}, mirror == false,\n * scaleMode == \"fit\". Also, the default scaleMode setting for\n * subscribers to the stream is \"fit\".\n *
\n * You can also set this property to a video\n * \n * MediaStreamTrack object. This lets you use the MediaStreamTrack object as the\n * video source for the published stream. For example, you can get a CanvasCaptureMediaStream\n * object by calling the captureStream() method of a HTMLCanvasElement, and then\n * you can call the getVideoTracks() method of the CanvasCaptureMediaStream object\n * to get a video MediaStreamTrack object. Or you can get an array of video MediaStreamTrack\n * object from the videoTracks property of an HTMLMediaElement object. Or you can\n * call the getLocalStreams() or getRemoteStreams() method of an\n * RTCPeerConnection object to get an array of MediaStream objects, and then call the\n * getVideoTracks() method of one of the MediaStream objects to get an array\n * of video MediaStreamTrack objects. Note that by default the publisher uses a microphone\n * as the audio source, so be sure to set the audioSource option if you want\n * to use a MediaStreamTrack as the audio source or if you do not want to publish an audio\n * track. The default mirror setting for a Publisher with a MediaStreamTrack video\n * source is false. You can also call\n * OT.getUserMedia() to get a MediaStream object that uses\n * the microphone and camera as the audio and video sources.\n *

Make sure that you have successfully connected to the\n * session before calling other methods of the Session object.\n *
\n *\n * The Session object dispatches a connectionCreated event when any client\n * (including your own) connects to the session.\n *
\n * The following code initializes a session and sets up an event listener for when the session\n * connects:\n *
\n *\n * var apiKey = \"\"; // Replace with your API key. See https://tokbox.com/account\n * var sessionID = \"\"; // Replace with your own session ID.\n * // See https://tokbox.com/developer/guides/create-session/.\n * var token = \"\"; // Replace with a generated token.\n * // See https://tokbox.com/developer/guides/create-token/.\n *\n * var session = OT.initSession(apiKey, sessionID);\n * session.connect(token, function(error) {\n * if (error) {\n * console.log(error.message);\n * } else {\n * // You have connected to the session. You could publish a stream now.\n * }\n * });\n * \n * \n *\n *
\n * exception (ExceptionEvent) — Dispatched\n * by the OT class locally in the event of an error.\n *
\n * connectionCreated (ConnectionEvent) —\n * Dispatched by the Session object on all clients connected to the session.\n *
\n * sessionConnected (SessionConnectEvent)\n * — Dispatched locally by the Session object when the connection is established. However,\n * you can pass a completion handler function in as the second parameter of the\n * connect() and use this function instead of a listener for the\n * sessionConnected event.\n *
connect() method succeeds or fails. This function takes one parameter —\n * error (see the Error object).\n * On success, the completionHandler function is not passed any\n * arguments. On error, the function is passed an error object parameter\n * (see the Error object). The\n * error object has two properties: code (an integer) and\n * message (a string), which identify the cause of the failure. The following\n * code adds a completionHandler when calling the connect() method:\n * \n * session.connect(token, function (error) {\n * if (error) {\n * console.log(error.message);\n * } else {\n * console.log(\"Connected to session.\");\n * }\n * });\n * \n * \n * Note that upon connecting to the session, the Session object dispatches a\n * sessionConnected event in addition to calling the completionHandler.\n * The SessionConnectEvent object, which defines the sessionConnected event,\n * includes connections and streams properties, which\n * list the connections and streams in the session when you connect.\n *
\n * Calling the disconnect() method ends your connection with the session. In the\n * course of terminating your connection, it also ceases publishing any stream(s) you were\n * publishing.\n *
\n * Session objects on remote clients dispatch streamDestroyed events for any\n * stream you were publishing. The Session object dispatches a sessionDisconnected\n * event locally. The Session objects on remote clients dispatch connectionDestroyed\n * events, letting other connections know you have left the session. The\n * {@link SessionDisconnectEvent} and {@link StreamEvent} objects that define the\n * sessionDisconnect and connectionDestroyed events each have a\n * reason property. The reason property lets the developer determine\n * whether the connection is being terminated voluntarily and whether any streams are being\n * destroyed as a byproduct of the underlying connection's voluntary destruction.\n *
\n * If the session is not currently connected, calling this method causes a warning to be logged.\n * See OT.setLogLevel().\n *
\n *\n *\n * Note: If you intend to reuse a Publisher object to publish to different sessions\n * (or the same session) sequentially, add an event listener for the streamDestroyed\n * event dispatched by the Publisher object (when it stops publishing). In the event listener,\n * call the preventDefault() method of the event object to prevent the Publisher's\n * video from being removed from the page.\n *
\n * sessionDisconnected\n * (SessionDisconnectEvent)\n * — Dispatched locally when the connection is disconnected.\n *
\n * connectionDestroyed (ConnectionEvent) —\n * Dispatched on other clients, along with the streamDestroyed event (as warranted).\n *
\n * streamDestroyed (StreamEvent) —\n * Dispatched on other clients if streams are lost as a result of the session disconnecting.\n *
publish() method starts publishing an audio-video stream to the session.\n * The audio-video stream is captured from a local microphone and webcam. Upon successful\n * publishing, the Session objects on all connected clients dispatch the\n * streamCreated event.\n * \n *\n * \n * You pass a Publisher object as the one parameter of the method. You can initialize a\n * Publisher object by calling the OT.initPublisher()\n * method. Before calling Session.publish().\n *
This method takes an alternate form: publish(targetElement: String | HTMLElement,\n * properties: Object, completionHandler: Function): Publisher — In this form, you do\n not pass a Publisher object into the function. Instead, you pass in a targetElement\n (the target HTML element or the ID of the target HTML element for the Publisher), an optional\n properties object that defines options for the Publisher (see\n OT.initPublisher()), and an optional completion handler function.\n * The method returns a new Publisher object, which starts sending an audio-video stream to the\n * session. The remainder of this documentation describes the form that takes a single Publisher\n * object as a parameter.\n *\n *
\n * A local display of the published stream is created on the web page by replacing\n * the specified element in the DOM with a streaming video display. The video stream\n * is automatically mirrored horizontally so that users see themselves and movement\n * in their stream in a natural way. If the width and height of the display do not match\n * the 4:3 aspect ratio of the video signal, the video stream is cropped to fit the\n * display.\n *
\n *\n *\n * If calling this method creates a new Publisher object and the OpenTok library does not\n * have access to the camera or microphone, the web page alerts the user to grant access\n * to the camera and microphone.\n *
\n *\n *\n * The OT object dispatches an exception event if the user's role does not\n * include permissions required to publish. For example, if the user's role is set to subscriber,\n * then they cannot publish. You define a user's role when you create the user token\n * (see Token creation overview).\n * You pass the token string as a parameter of the connect() method of the Session\n * object. See ExceptionEvent and\n * OT.on().\n *
\n * The application throws an error if the session is not connected.\n *
\n *\n *\n * exception (ExceptionEvent) — Dispatched\n * by the OT object. This can occur when user's role does not allow publishing (the\n * code property of event object is set to 1500); it can also occur if the\n * connection fails to connect (the code property of event object is set to 1013).\n * WebRTC is a peer-to-peer protocol, and it is possible that connections will fail to connect.\n * The most common cause for failure is a firewall that the protocol cannot traverse.\n *
\n * streamCreated (StreamEvent) —\n * The stream has been published. The Session object dispatches this on all clients\n * subscribed to the stream, as well as on the publisher's client.\n *
\n * The following example publishes a video once the session connects:\n *
\n *\n * var apiKey = \"\"; // Replace with your API key. See https://tokbox.com/account\n * var sessionId = \"\"; // Replace with your own session ID.\n * // https://tokbox.com/developer/guides/create-session/.\n * var token = \"\"; // Replace with a generated token that has been assigned the publish role.\n * // See https://tokbox.com/developer/guides/create-token/.\n * var session = OT.initSession(apiKey, sessionID);\n * session.connect(token, function(error) {\n * if (error) {\n * console.log(error.message);\n * } else {\n * var publisherOptions = {width: 400, height:300, name:\"Bob's stream\"};\n * // This assumes that there is a DOM element with the ID 'publisher':\n * publisher = OT.initPublisher('publisher', publisherOptions);\n * session.publish(publisher);\n * }\n * });\n * \n *\n * @param {Publisher} publisher A Publisher object, which you initialize by calling the\n * OT.initPublisher() method.\n *\n * @param {Function} completionHandler (Optional) A function to be called when the call to the\n * publish() method succeeds or fails. This function takes one parameter —\n * error. On success, the completionHandler function is not passed any\n * arguments. On error, the function is passed an error object parameter\n * (see the Error object). The\n * error object has two properties: code (an integer) and\n * message (a string), which identify the cause of the failure. Calling\n * publish() fails if the role assigned to your token is not \"publisher\" or\n * \"moderator\"; in this case the error.name property is set to\n * \"OT_PERMISSION_DENIED\". Calling publish() also fails if the\n * client fails to connect; in this case the error.name property is set to\n * \"OT_NOT_CONNECTED\". The following code adds a completion handler when\n * calling the publish() method:\n * \n * session.publish(publisher, null, function (error) {\n * if (error) {\n * console.log(error.message);\n * } else {\n * console.log(\"Publishing a stream.\");\n * }\n * });\n * \n *\n * @returns The Publisher object for this stream.\n *\n * @method #publish\n * @memberOf Session\n */\n this.publish = function (publisher, properties, completionHandler) {\n if (typeof publisher === 'function') {\n completionHandler = publisher;\n publisher = undefined;\n }\n\n if (typeof properties === 'function') {\n completionHandler = properties;\n properties = undefined;\n }\n\n completionHandler = completionHandler || function () {};\n\n if (this.isNot('connected')) {\n analytics.logError(\n 1010,\n 'OT.exception',\n 'We need to be connected before you can publish',\n null,\n {\n action: 'Publish',\n variation: 'Failure',\n failureReason: 'unconnected',\n failureCode: ExceptionCodes.NOT_CONNECTED,\n failureMessage: 'We need to be connected before you can publish',\n sessionId: _sessionId,\n streamId: (publisher && publisher.stream) ? publisher.stream.id : null,\n p2p: this.sessionInfo ? this.sessionInfo.p2pEnabled : undefined,\n messagingServer: this.sessionInfo ? this.sessionInfo.messagingServer : null,\n partnerId: _apiKey,\n }\n );\n\n dispatchOTError(\n otError(\n errors.NOT_CONNECTED,\n new Error('We need to be connected before you can publish'),\n ExceptionCodes.NOT_CONNECTED\n ),\n completionHandler\n );\n\n return null;\n }\n\n if (!permittedTo('publish')) {\n const errorMessage = 'This token does not allow publishing.

\n * Note: If you intend to reuse a Publisher object to publish to different sessions\n * (or the same session) sequentially, add an event listener for the streamDestroyed\n * event dispatched by the Publisher object (when it stops publishing). In the event listener,\n * call the preventDefault() method of the event object to prevent the Publisher's\n * video from being removed from the page.\n *
\n * streamDestroyed (StreamEvent) —\n * The stream associated with the Publisher has been destroyed. Dispatched on by the\n * Publisher on on the Publisher's browser. Dispatched by the Session object on\n * all other connections subscribing to the publisher's stream.\n *

Set this to 'relay' to force connectivity through TURN always\n * and ignore all other ICE candidates.\n * \n * customServers (Array) — Set this to an array of objects defining\n * your custom TURN servers. Each object corresponds to one custom TURN server, and it\n * includes the following properties:\n *
\n *
urls (String or Array of Strings) — A string or an array of strings,\n * where each string is a URL supported by the TURN server (and this may be only one URL).\n * username (String, optional) — The username for the TURN server defined\n * in this object.\n * credential (String, optional) — The credential string for the TURN server\n * defined in this object.\n * streams property of the sessionConnected\n * and streamCreated events (see\n * SessionConnectEvent and\n * StreamEvent).\n * \n * \n * The subscribed stream is displayed on the local web page by replacing the specified element\n * in the DOM with a streaming video display.

See the insertMode property of the properties parameter. If\n * you do not specify a targetElement, the application appends a new DOM element\n * to the HTML body.\n *\n * @param {Object} properties This is an object that contains the following properties:\n * audioVolume (Number) — The desired audio volume, between 0 and\n * 100, when the Subscriber is first opened (default: 50). After you subscribe to the\n * stream, you can adjust the volume by calling the\n * setAudioVolume() method of the\n * Subscriber object. This volume setting affects local playback only; it does not affect\n * the stream's volume on other clients.fitMode (String) — Determines how the video is displayed if the its\n * dimensions do not match those of the DOM element. You can set this property to one of\n * the following values:\n * \n *
\"cover\" — The video is cropped if its dimensions do not match\n * those of the DOM element. This is the default setting for videos that have a\n * camera as the source (for Stream objects with the videoType property\n * set to \"camera\").\n * \"contain\" — The video is letterboxed if its dimensions do not\n * match those of the DOM element. This is the default setting for screen-sharing\n * videos (for Stream objects with the videoType property set to\n * \"screen\").\n * height (Number or String) — The desired initial height of the displayed\n * video in the HTML page (default: 198 pixels). You can specify the number of pixels as\n * either a number (such as 300) or a string ending in \"px\" (such as \"300px\"). Or you can\n * specify a percentage of the size of the parent element, with a string ending in \"%\"\n * (such as \"100%\"). Note: To resize the video, adjust the CSS of the subscriber's\n * DOM element (the element property of the Subscriber object) or (if the\n * height is specified as a percentage) its parent DOM element (see\n * \n * Resizing or repositioning a video).\n * true, the default) or not (false). The default UI element\n * contains user interface controls, a video loading indicator, and automatic video cropping\n * or letterboxing, in addition to the video. (If you leave insertDefaultUI\n * set to true, you can control individual UI settings using the\n * fitMode, showControls, and style options.)\n * \n * If you set this option to false, OpenTok.js does not insert a default UI\n * element in the HTML DOM, and the element property of the Subscriber object is\n * undefined. The Subscriber object dispatches a\n * videoElementCreated event when\n * the video element (or in Internet Explorer the object element\n * containing the video) is created. The element property of the event object\n * is a reference to the Subscriber's video (or object) element.\n * Add it to the HTML DOM to display the video.\n *
\n * Set this option to false if you want to move the Publisher's\n * video element (or its object element in Internet Explorer) in\n * the HTML DOM.\n *
\n * If you set this to false, do not set the targetElement\n * parameter. (This results in an error passed into to the OT.initPublisher()\n * callback function.) To add the video to the HTML DOM, add an event listener for the\n * videoElementCreated event, and then add the element property of\n * the event object into the HTML DOM.\n *
insertMode (String) — Specifies how the Subscriber object will\n * be inserted in the HTML DOM. See the targetElement parameter. This\n * string can have the following values:\n * \n *
\"replace\" — The Subscriber object replaces contents of the\n * targetElement. This is the default.\"after\" — The Subscriber object is a new element inserted\n * after the targetElement in the HTML DOM. (Both the Subscriber and targetElement\n * have the same parent element.)\"before\" — The Subscriber object is a new element inserted\n * before the targetElement in the HTML DOM. (Both the Subscriber and targetElement\n * have the same parent element.)\"append\" — The Subscriber object is a new element added as a\n * child of the targetElement. If there are other child elements, the Subscriber is\n * appended as the last child element of the targetElement.preferredFrameRate (Number) — The preferred frame rate of the subscriber's\n * video. Lowering the preferred frame rate lowers video quality on the subscribing client,\n * but it also reduces network and CPU usage. You may want to use a lower frame rate for\n * subscribers to a stream that is less important than other streams.\n * \n * This property only applies when subscribing to a stream that uses the\n * \n * scalable video feature. Scalable video is available:\n *
\n * In streams that do not use scalable video, setting this property has no effect.\n *
\n * Note: The frame rate for scalable video streams automatically adjusts for each\n * subscriber, based on network conditions and CPU usage, even if you do not call this method.\n * Call this method if you want to set a maximum frame rate for this subscriber.\n *
\n *
\n * Not every frame rate is available to a subscriber. When you set the preferred frame rate for\n * the subscriber, OpenTok.js picks the best frame rate available that matches your setting.\n * The frame rates available are based on the value of the Subscriber object's\n * stream.frameRate property, which represents the maximum value available for the\n * stream. The actual frame rates available depend, dynamically, on network and CPU resources\n * available to the publisher and subscriber.\n *
\n * You can dynamically change the preferred frame rate used by calling the\n * setPreferredFrameRate() method of the Subscriber object.\n *
preferredResolution (Object) — The preferred resolution of the subscriber's\n * video. Set this to an object with two properties: width and height\n * (both numbers), such as {width: 320, height: 240}. Lowering the preferred video\n * resolution lowers video quality on the subscribing client, but it also reduces network and CPU\n * usage. You may want to use a lower resolution based on the dimensions of subscriber's video on\n * the web page. You may want to use a resolution for subscribers to a stream that is less\n * important (and smaller) than other streams.\n * \n * This property only applies when subscribing to a stream that uses the\n * \n * scalable video feature. Scalable video is available:\n *
\n * In streams that do not use scalable video, setting this property has no effect.\n *
\n * Not every resolution is available to a subscriber. When you set the preferred resolution,\n * OpenTok.js and the video encoder pick the best resolution available that matches your\n * setting. The resolutions available depend on the resolution of the published stream.\n * The Subscriber object's stream.resolution property represents the highest\n * resolution available for the stream. Each of the resolutions available for a stream will use\n * the same aspect ratio. The actual resolutions available depend, dynamically, on network\n * and CPU resources available to the publisher and subscriber.\n *
\n * You can dynamically change the preferred video resolution used by calling the\n * setPreferredResolution() method of the Subscriber object.\n *
showControls (Boolean) — Whether to display the built-in user interface\n * controls for the Subscriber (default: true). These controls include the name\n * display, the audio level indicator, the speaker control button, the video disabled indicator,\n * and the video disabled warning icon. You can turn off all user interface controls by setting\n * this property to false. You can control the display of individual user interface\n * controls by leaving this property set to true (the default) and setting\n * individual properties of the style property.\n * style (Object) — An object containing properties that define the initial\n * appearance of user interface controls of the Subscriber. The style object\n * includes the following properties:\n * audioBlockedDisplayMode (String) — Whether to display\n * the default audio blocked icon in Subscribers (in browsers where audio\n * autoplay is blocked). Possible values are: \"auto\" (the default,\n * icon is displayed when the audio is disabled) and \"off\" (the icon\n * is not displayed). Set this to \"off\" if you want to display\n * your own UI element showing that the audio is blocked. In response to an\n * HTML element dispatching a click event, you can call the\n * OT.unblockAudio() method to start audio\n * playback in this and all other blocked subscribers.audioLevelDisplayMode (String) — How to display the audio level\n * indicator. Possible values are: \"auto\" (the indicator is displayed when the\n * video is disabled), \"off\" (the indicator is not displayed), and\n * \"on\" (the indicator is always displayed).backgroundImageURI (String) — A URI for an image to display as\n * the background image when a video is not displayed. (A video may not be displayed if\n * you call subscribeToVideo(false) on the Subscriber object). You can pass an\n * http or https URI to a PNG, JPEG, or non-animated GIF file location. You can also use the\n * data URI scheme (instead of http or https) and pass in base-64-encrypted\n * PNG data, such as that obtained from the\n * Subscriber.getImgData() method. (For example,\n * you could set the property to a value returned by calling getImgData() on\n * a previous Subscriber object.) If the URL or the image data is invalid, the\n * property is ignored (the attempt to set the image fails silently).buttonDisplayMode (String) — How to display the speaker controls\n * Possible values are: \"auto\" (controls are displayed when the stream is first\n * displayed and when the user mouses over the display), \"off\" (controls are not\n * displayed), and \"on\" (controls are always displayed).nameDisplayMode (String) — Whether to display the stream name.\n * Possible values are: \"auto\" (the name is displayed when the stream is first\n * displayed and when the user mouses over the display), \"off\" (the name is not\n * displayed), and \"on\" (the name is always displayed).videoDisabledDisplayMode (String) — Whether to display the video\n * disabled indicator and video disabled warning icons for a Subscriber. These icons\n * indicate that the video has been disabled (or is in risk of being disabled for\n * the warning icon) due to poor stream quality. This style only applies to the Subscriber\n * object. Possible values are: \"auto\" (the icons are automatically when the\n * displayed video is disabled or in risk of being disabled due to poor stream quality),\n * \"off\" (do not display the icons), and \"on\" (display the\n * icons). The default setting is \"auto\"subscribeToAudio (Boolean) — Whether to initially subscribe to audio\n * (if available) for the stream (default: true).subscribeToVideo (Boolean) — Whether to initially subscribe to video\n * (if available) for the stream (default: true).testNetwork (Boolean) — Whether, when subscribing to a stream\n * published by the local client, you want to have the stream come from the OpenTok Media\n * Router (true) or if you want the DOM to simply to display the local camera's\n * video (false). Set this to true when you want to use the\n * Subscriber.getStats() method to check statistics\n * for a stream you publish. This setting only applies to streams published by the local\n * client in a session that uses the OpenTok Media Router (sessions with the\n * media mode\n * set to routed), not in sessions with the media mode set to relayed. The default value is\n * false.width (Number or String) — The desired initial width of the displayed\n * video in the HTML page (default: 264 pixels). You can specify the number of pixels as\n * either a number (such as 400) or a string ending in \"px\" (such as \"400px\"). Or you can\n * specify a percentage of the size of the parent element, with a string ending in \"%\"\n * (such as \"100%\"). Note: To resize the video, adjust the CSS of the subscriber's\n * DOM element (the element property of the Subscriber object) or (if the\n * width is specified as a percentage) its parent DOM element (see\n * \n * Resizing or repositioning a video).\n * subscribe() method succeeds or fails. This function takes one parameter —\n * error. On success, the completionHandler function is not passed any\n * arguments. On error, the function is passed an error object, defined by the\n * Error class, has two properties: code (an integer) and\n * message (a string), which identify the cause of the failure. The following\n * code adds a completionHandler when calling the subscribe() method:\n * \n * session.subscribe(stream, \"subscriber\", null, function (error) {\n * if (error) {\n * console.log(error.message);\n * } else {\n * console.log(\"Subscribed to stream: \" + stream.id);\n * }\n * });\n * \n *\n * @signature subscribe(stream, targetElement, properties, completionHandler)\n * @returns {Subscriber} The Subscriber object for this stream.

If your client loses its\n * connection to the OpenTok session, due to a drop in network connectivity, the client\n * attempts to reconnect to the session, and the Session object dispatches a\n * reconnecting event.

You can use the type to\n * filter signals when setting an event handler for the signal:type event\n * (where you replace type with the type string). The maximum length of the\n * type string is 128 characters, and it must contain only letters (A-Z and a-z),\n * numbers (0-9), '-', '_', and '~'.Each property is optional.
