[**Red5 Pro WebRTC SDK v15.2.0**](../README.md) *** [Red5 Pro WebRTC SDK](../globals.md) / WHIPClient # Class: WHIPClient WHIP-based Publisher. The `WHIPClient` - under the hood - is based on the [WebRTC-HTTP ingestion](https://www.ietf.org/archive/id/draft-ietf-wish-whip-01.html)(WHIP) protocol providing the ability to negotation and establish a connection using HTTP/S requests. This removes the requirement for a WebSocket, which historically has been used for the role of negotiation and connection. This provides a standardized - and _blazingly fast_ - way to establish and publish a live stream using WebRTC. ## Extends - [`EventEmitter`](EventEmitter.md) ## Constructors ### Constructor > **new WHIPClient**(`url?`, `element?`, `additionalOptions?`): `WHIPClient` Constructor. Providing arguments will automatically kick of connection sequence. Leaving arguments unset allows for more control and follows same pattern of init. #### Parameters ##### url? `string` Optional endpoint for WHIP. Example: https://your-red5pro.com/live/whip/endpoint/stream1 ##### element? `HTMLMediaElement` Optional media element to play media in. ##### additionalOptions? [`RTCWhipPublisherConfigType`](../type-aliases/RTCWhipPublisherConfigType.md) Optional additional options to override defaults. #### Returns `WHIPClient` #### Overrides [`EventEmitter`](EventEmitter.md).[`constructor`](EventEmitter.md#constructor) ## Accessors ### options #### Get Signature > **get** **options**(): `undefined` \| [`RTCWhipPublisherConfigType`](../type-aliases/RTCWhipPublisherConfigType.md) Get the options for the WHIPClient. ##### Returns `undefined` \| [`RTCWhipPublisherConfigType`](../type-aliases/RTCWhipPublisherConfigType.md) ## Methods ### callServer() > **callServer**(`methodName`, `args`): `Promise`\<`any`\> Call a method on the server. #### Parameters ##### methodName `string` The name of the method to call. ##### args `any` The arguments to call the method with. #### Returns `Promise`\<`any`\> *** ### emit() > **emit**(`type`, `data`): `void` Emit an event on the WHIPClient. #### Parameters ##### type `string` The type of event to emit. ##### data `any` The data to emit. #### Returns `void` *** ### getDataChannel() > **getDataChannel**(): `undefined` \| `RTCDataChannel` Get the DataChannel for the WHIPClient. #### Returns `undefined` \| `RTCDataChannel` *** ### getMediaStream() > **getMediaStream**(): `undefined` \| `MediaStream` Get the MediaStream generated for the WHIPClient. #### Returns `undefined` \| `MediaStream` *** ### getMessageTransport() > **getMessageTransport**(): `undefined` \| `MessageTransport` Get the MessageTransport for the WHIPClient. #### Returns `undefined` \| `MessageTransport` *** ### getOptions() > **getOptions**(): `undefined` \| [`RTCWhipPublisherConfigType`](../type-aliases/RTCWhipPublisherConfigType.md) Get the options for the WHIPClient. #### Returns `undefined` \| [`RTCWhipPublisherConfigType`](../type-aliases/RTCWhipPublisherConfigType.md) *** ### getPeerConnection() > **getPeerConnection**(): `undefined` \| `RTCPeerConnection` Get the PeerConnection for the WHIPClient. #### Returns `undefined` \| `RTCPeerConnection` *** ### getPubNubClient() > **getPubNubClient**(): `undefined` \| [`PubNubClient`](PubNubClient.md) Get the PubNub client for the WHIPClient. #### Returns `undefined` \| [`PubNubClient`](PubNubClient.md) *** ### getType() > **getType**(): `string` Get the type of the WHIPClient (RTC). #### Returns `string` *** ### init() > **init**(`options`): `Promise`\<`WHIPClient`\> Initialize the WHIPClient. #### Parameters ##### options [`RTCWhipPublisherConfigType`](../type-aliases/RTCWhipPublisherConfigType.md) The options to use for initialization. #### Returns `Promise`\<`WHIPClient`\> *** ### initWithStream() > **initWithStream**(`options`, `stream`): `Promise`\<`WHIPClient`\> Initialize the WHIPClient with a MediaStream. Doing so will skip the SDK attempting to generate a MediaStream through browser-based media APIs. #### Parameters ##### options [`RTCWhipPublisherConfigType`](../type-aliases/RTCWhipPublisherConfigType.md) The options to use for initialization. ##### stream `MediaStream` The stream to use for initialization. #### Returns `Promise`\<`WHIPClient`\> *** ### monitorStats() > **monitorStats**(`stats?`): `WHIPClient` Monitor the statistics of the MediaStream being published to the server over the underlying RTCPeerConnection.. #### Parameters ##### stats? [`StatsConfig`](../type-aliases/StatsConfig.md) The statistics configuration. #### Returns `WHIPClient` *** ### muteAudio() > **muteAudio**(): `void` Mute the audio being published to the server. #### Returns `void` *** ### muteVideo() > **muteVideo**(): `void` Mute the video being published to the server. #### Returns `void` *** ### off() > **off**(`type`, `fn`): `void` Remove an event listener from the WHIPClient. #### Parameters ##### type `string` The type of event to remove the listener from. ##### fn (`event`) => `void` The function to remove the listener from. #### Returns `void` #### Overrides [`EventEmitter`](EventEmitter.md).[`off`](EventEmitter.md#off) *** ### on() > **on**(`type`, `fn`): `void` Add an event listener to the WHIPClient. #### Parameters ##### type `string` The type of event to listen for. ##### fn (`event`) => `void` The function to call when the event is triggered. #### Returns `void` #### Overrides [`EventEmitter`](EventEmitter.md).[`on`](EventEmitter.md#on) *** ### publish() > **publish**(`streamName?`): `Promise`\<`WHIPClient`\> Publish the MediaStream to the server. #### Parameters ##### streamName? `string` The name of the stream to publish. #### Returns `Promise`\<`WHIPClient`\> *** ### send() > **send**(`methodName`, `data`): `undefined` \| `Promise`\<`boolean`\> Send a message to the server. #### Parameters ##### methodName `string` The name of the method to send. ##### data `any` The data to send. #### Returns `undefined` \| `Promise`\<`boolean`\> *** ### sendLog() > **sendLog**(`level`, `message`): `void` Send a log message to the server. #### Parameters ##### level `string` The level of the log message. ##### message `any` The message to send. #### Returns `void` *** ### sendPubNub() > **sendPubNub**(`channel`, `message`): `Promise`\<`boolean`\> Send a message to the PubNub channel. #### Parameters ##### channel `string` The channel to send the message to. ##### message `any` The message to send. #### Returns `Promise`\<`boolean`\> *** ### subscribePubNub() > **subscribePubNub**(`channel`, `options`): `Promise`\<`boolean`\> Subscribe to a PubNub channel. #### Parameters ##### channel `string` The channel to subscribe to. ##### options `any` The options to use for subscription. #### Returns `Promise`\<`boolean`\> *** ### trigger() > **trigger**(`event`): `void` Trigger an event on the WHIPClient. #### Parameters ##### event [`Event`](Event.md) The event to trigger. #### Returns `void` #### Overrides [`EventEmitter`](EventEmitter.md).[`trigger`](EventEmitter.md#trigger) *** ### unmonitorStats() > **unmonitorStats**(): `WHIPClient` Unmonitor the statistics of the MediaStream being published to the server over the underlying RTCPeerConnection. #### Returns `WHIPClient` *** ### unmuteAudio() > **unmuteAudio**(): `void` Unmute the audio being published to the server. #### Returns `void` *** ### unmuteVideo() > **unmuteVideo**(): `void` Unmute the video being published to the server. #### Returns `void` *** ### unpublish() > **unpublish**(`internal`): `Promise`\<`void`\> Unpublish the MediaStream from the server. #### Parameters ##### internal `boolean` = `false` Whether the unpublish is internal (i.e. not triggered by the user). #### Returns `Promise`\<`void`\> *** ### unsubscribePubNub() > **unsubscribePubNub**(`channel`): `Promise`\<`boolean`\> Unsubscribe from a PubNub channel. #### Parameters ##### channel `string` The channel to unsubscribe from. #### Returns `Promise`\<`boolean`\>
