Download the PHP package rtippin/janus-client without Composer

Laravel Janus Gateway Client

This package provides a client to fluently interact with your Janus Gateway Server

Prerequisites

Included

• Core REST API wrapper to interact with janus.
• VideoRoom plugin wrapper.

Fluent, convenient, clean.

Installation

Via Composer

Publish the config file

Config

• server_endpoint is the main HTTP endpoint for your janus server.
• admin_server_endpoint is the admin HTTP endpoint for your janus server.
• verify_ssl enables or disables our Guzzle HTTP calls from verifying the SSL.
• debug When enabled, each request in a cycle will dump the payload and responses.
• admin_secret API secret to access the admin endpoint.
• api_secret The general API secret.
• video_room_secret Optional video room secret to protect creates.

General Usage

• You may choose to use our provided facade, or dependency injection to access our core Janus class.

Notice, Janus is registered as a singleton. Once you instantiate our class, it will be kept in memory with its current state for that request cycle.

Obtaining the Janus client

Using Facade

Using Dependency Injection

info()

• Returns the janus server info array.

ping()

• Ping will always return an array (even if an exception is thrown), containing pong as true|false, along with server latency.

debug(bool $debug = true)

• Enable debugging/dumps on the fly by calling to the debug method on Janus. This will dump each HTTP call's payload, response, and latency.

connect()

• Connect will initiate a handshake with janus to set our session ID for any following request. This is a fluent method and can be chained.

attach(string $plugin)

• Attach to a janus plugin to set our handle ID. All following API calls in this request cycles will go to this plugin unless you call detach or disconnect. This is a fluent method and can be chained.

detach()

• Detach from the current plugin/handle. This is a fluent method and can be chained.

disconnect()

• Disconnect from janus, destroying our session and handle/plugin. This is a fluent method and can be chained.

message(array $message, $jsep = null)

• Send janus our message. This is usually called once attached to a plugin, and sends commands to janus. This is a fluent method and can be chained.

trickle($candidate)

• Send a trickle candidate to janus. This is a fluent method and can be chained.

server()

• Returns the underlying janus server class, allowing you to set configs, or access current payloads/responses in the cycle.

Example Cycle

• Say we want to obtain a list of video rooms, 4 calls must be made.
  • First we connect which sets our session id.
  • Then we want to attach to the video room plugin to set our handle id.
  • Once attached, we send janus our command message to list rooms.
  • If no further calls need to be made, we then disconnect which will reset our session and handle ID's. This also ensures state sessions are not kept in your janus servers memory.

Shared Plugin Methods

All Plugin methods will return the plugin response array from janus directly.

• ['plugindata']['data'] contents returned.

Examples using VideoRoom plugin

{JanusPlugin}->withoutDisconnect() | {JanusPlugin}->disconnect(bool $force = false)

• If you plan to use many commands in one cycle while attached to the same plugin, calling this method will only create one connect and attach call to reuse our session and handle ID's.
• When you have completed all individual calls, you must manually call to the parent Janus to disconnect, or force it within the current plugin instance, using disconnect(true).
• These are fluent methods and can be chained.

Example video room call to remove all rooms

{JanusPlugin}->getPluginResponse(?string $key = null)

• Get the API response from the last plugin method called.
  • ['plugindata']['data'] contents will be returned.

{JanusPlugin}->getPluginPayload(?string $key = null)

• Get the API payload for the last plugin method called.

Video Room

For full docs relating to the video room plugin and its responses, please check the Official Docs

• You may access the video room plugin through the core Janus class/facade, or dependency injection of the core VideoRoom class.
• Each main janus method completes a full cycle (connect, attach, message, disconnect) unless you specify withoutDisconnect().

Using Facade

Using Dependency Injection

list()

• Returns a list of the available rooms (excluded those configured or created as private rooms).

exists(int $room)

• Check whether a room exists.

create(array $params = [], bool $usePin = true, bool $useSecret = true)

• Create a new video room. By default, we will create a PIN and SECRET for you, as well as set certain properties. Any params you set will override any of our defaults.
  • We will merge the PIN/SECRET with the returned array from the janus plugin response, so that you may save it if needed.

edit(int $room, array $params, ?string $secret = null)

• Edit the allowed properties of an existing room.

allowed(int $room, string $action, ?array $allowed = null, ?string $secret = null)

• You can configure whether to check tokens or add/remove people who can join a room.

kick(int $room, int $participantID, ?string $secret = null)

• Kick a participant from the room.

listParticipants(int $room)

• Get a list of the participants in a specific room.

listForwarders(int $room, ?string $secret = null)

• Get a list of all the forwarders in a specific room.

destroy(int $room, ?string $secret = null)

• Destroy an existing video room.

moderate(int $room, int $participantID, bool $mute, ?string $mid = null, ?string $secret = null)

• Forcibly mute/unmute any of the media streams sent by participants.

enableRecording(int $room, bool $record, ?string $secret = null)

• Enable or disable recording on all participants while the conference is in progress.

Example Cycle using many methods without disconnecting between them.
