Adds a stream to a currently running broadcast that was started with the the streamMode set to StreamMode.Manual. You can call the method repeatedly with the same stream ID, to toggle the stream's audio or video in the broadcast.

Parameters

broadcastId	The broadcast ID.
streamId	The stream ID.
hasAudio	Whether the broadcast should include the stream's audio (true, the default) or not (false).
hasVideo	Whether the broadcast should include the stream's video (true, the default) or not (false).

OpenTokArgumentException

Creates a new Vonage Video API session.

Vonage Video API sessions do not expire. However, authentication tokens do expire (see the generateToken() method). Also note that sessions cannot explicitly be destroyed.

A session ID string can be up to 255 characters long.

Calling this method results in an OpenTokException in the event of an error. Check the error message for details.

You can also create a session using the OpenTok REST API or by logging in to your TokBox account.

Parameters

location	An IP address that the Vonage Video API servers will use to situate the session in its global network. If you do not set a location hint, the Vonage Video API servers will be based on the first client connecting to the session.
mediaMode	Whether the session will transmit streams using the Vonage Video API Media Router (MediaMode.ROUTED) or not (MediaMode.RELAYED). By default, the setting is MediaMode.RELAYED. With the parameter set to MediaMode.RELAYED, the session will attempt to transmit streams directly between clients. If clients cannot connect due to firewall restrictions, the session uses the OpenTok TURN server to relay streams. The OpenTok Media Router provides the following benefits: The Vonage Video API Media Router can decrease bandwidth usage in multiparty sessions. (When the mediaMode parameter is set to MediaMode.ROUTED, each client must send a separate audio-video stream to each client subscribing to it.) The Vonage Video API Media Router can improve the quality of the user experience through audio fallback and video recovery With these features, if a client's connectivity degrades to a degree that it does not support video for a stream it's subscribing to, the video is dropped on that client (without affecting other clients), and the client receives audio only. If the client's connectivity improves, the video returns. The Vonage Video API Media Router supports the archiving feature, which lets you record, save, and retrieve Vonage Video API sessions.
archiveMode	Whether the session is automatically archived (ArchiveMode.ALWAYS) or not (ArchiveMode.MANUAL). By default, the setting is ArchiveMode.MANUAL and you must call the StartArchive method of the OpenTok object to start archiving. To archive the session (either automatically or not), you must set the mediaMode parameter to MediaMode.ROUTED
encryption	Enables end-to-end media encryption in routed sessions.
archiveName	Name of the archives in auto archived sessions. A session that begins with archive mode 'always' will be using this archive name for all archives of that session. Passing 'archiveName' with archive mode 'manual' will cause an error response.
archiveResolution	Resolution of the archives in auto archived sessions. A session that begins with archive mode 'always' will be using this resolution for all archives of that session. Passing 'archiveResolution' with archive mode 'manual' will cause an error response.

Returns

A Session object representing the new session. The Session.Id property of the Session is the session ID, which uniquely identifies the session. You will use this session ID in the client SDKs to identify the session. For example, when using the OpenTok.js library, use the session ID when calling the OT.initSession() method (to initialize an Vonage Video API session).

Creates a new Vonage Video API session.

Vonage Video API sessions do not expire. However, authentication tokens do expire (see the generateToken() method). Also note that sessions cannot explicitly be destroyed.

A session ID string can be up to 255 characters long.

Calling this method results in an OpenTokException in the event of an error. Check the error message for details.

You can also create a session using the OpenTok REST API or by logging in to your TokBox account.

Parameters

location	An IP address that the Vonage Video API servers will use to situate the session in its global network. If you do not set a location hint, the Vonage Video API servers will be based on the first client connecting to the session.
mediaMode	Whether the session will transmit streams using the Vonage Video API Media Router (MediaMode.ROUTED) or not (MediaMode.RELAYED). By default, the setting is MediaMode.RELAYED. With the parameter set to MediaMode.RELAYED, the session will attempt to transmit streams directly between clients. If clients cannot connect due to firewall restrictions, the session uses the OpenTok TURN server to relay streams. The OpenTok Media Router provides the following benefits: The Vonage Video API Media Router can decrease bandwidth usage in multiparty sessions.

If the client's connectivity improves, the video returns. The Vonage Video API Media Router supports the archiving feature, which lets you record, save, and retrieve Vonage Video API sessions.
archiveMode	Whether the session is automatically archived (ArchiveMode.ALWAYS) or not (ArchiveMode.MANUAL). By default, the setting is ArchiveMode.MANUAL and you must call the StartArchive method of the OpenTok object to start archiving. To archive the session (either automatically or not), you must set the mediaMode parameter to MediaMode.ROUTED
encryption	Enables end-to-end media encryption in routed sessions.
archiveName	Name of the archives in auto archived sessions. A session that begins with archive mode 'always' will be using this archive name for all archives of that session. Passing 'archiveName' with archive mode 'manual' will cause an error response.
archiveResolution	Resolution of the archives in auto archived sessions. A session that begins with archive mode 'always' will be using this resolution for all archives of that session. Passing 'archiveResolution' with archive mode 'manual' will cause an error response.

Returns

A Session object representing the new session. The Session.Id property of the Session is the session ID, which uniquely identifies the session. You will use this session ID in the client SDKs to identify the session. For example, when using the OpenTok.js library, use the session ID when calling the OT.initSession() method (to initialize an Vonage Video API session).

dvr	Whether to enable DVR functionality — rewinding, pausing, and resuming — in players that support it (true), or not (false, the default). With DVR enabled, the HLS URL will include a ?DVR query string appended to the end. See DVR functionality
lowLatency	Whether to enable low-latency mode for the HLSstream. Some HLS players do not support low-latency mode. This feature is incompatible with DVR mode HLS broadcasts. See Low-latency HLS broadcasts
multiBroadcastTag	Set this to support multiple broadcasts for the same session simultaneously. Set this to a unique string for each simultaneous broadcast of an ongoing session. See Simultaneous broadcasts.
hasAudio	Whether the broadcast has audio (default is true).
hasVideo	Whether the broadcast has video (default is true).
