kurento client php

kurento client php

Kurento WebRTC 媒體伺服器的kurento client php函式庫，它實作了 Kurento 協定的用戶端

安裝

安裝此程式庫的最簡單方法是使用composer 。更新你的composer.json

    "repositories" : [
        {
            "type" : "vcs" ,
            "url" : "https://github.com/rukavina/kurento-client-php"
        }
    ] ,
    "require" : {
        "rukavinamilan/kurento-client-php" : "dev-master"
    }

並運行

 composer install

用法

這是你好世界的例子。在官方教學頁面上閱讀更多內容。

 <?php
//composer autoload included
require_once ( " vendor/autoload.php " );

class DemoApp{
    protected $ offer = null ;
    protected $ loop ;
    protected $ logger ;
    protected $ wsUrl ;
    protected $ client ;


    function __construct ( $ offer , $ wsUrl ) {
        $ this -> offer = $ offer ;
        $ this -> wsUrl = $ wsUrl ;
        //required react even loop
        $ this -> loop =  React  EventLoop Factory:: create ();

        $ this -> logger = new  Zend  Log  Logger ();                
        $ writer = new  Zend  Log  Writer  Null ();        
        $ this -> logger -> addWriter ( $ writer );
    }
    
    public function run (){
        $ this -> client =  MgKurentoClient KurentoClient:: create ( $ this -> wsUrl , $ this -> loop , $ this -> logger , function ( $ client ){
            $ this -> client -> createMediaPipeline ( function ( $ pipeline , $ success , $ data ){
                $ webRtcEndpoint = new  MgKurentoClient  WebRtcEndpoint ( $ pipeline );
                $ webRtcEndpoint -> build ( function ( $ webRtcEndpoint , $ success , $ data ){
                    $ webRtcEndpoint -> connect ( $ webRtcEndpoint , function ( $ success , $ data ) use ( $ webRtcEndpoint ){
                        /* @var $webRtcEndpoint MgKurentoClientWebRtcEndpoint */
                        $ webRtcEndpoint -> processOffer ( $ this -> offer , function ( $ success , $ data ){
                            echo $ data [ ' value ' ];
                            //we don't need the loop anymore , we're exiting now
                            $ this -> loop -> stop ();
                        });
                    });
                });
            });    
        });
        $ this -> loop -> run ();
    }

}

/*
 * Starting here
 */

//get raw post body
$ offer = file_get_contents ( ' php://input ' );
//init the app
$ demoApp = new DemoApp ( $ offer , ' ws://127.0.0.1:8888/kurento ' );
//start the app
$ demoApp -> run ();

通用元素

如果某些刪除物件沒有直接實作為 php 類，您仍然可以透過通用MediaObject類別建立和使用它們。它提供了通用方法：

    public function remoteCreate( $ remoteType , callable $ callback , array $ params = array ());    
    public function remoteInvoke( $ operation , $ operationParams , callable $ callback );    
    public function remoteRelease( callable $ callback );    
    protected function remoteSubscribe( $ type , $ onEvent , callable $ callback );    
    public function remoteUnsubscribe( $ subscription , callable $ callback );

可以使用通用類別/方法來實現相同的 hello world 範例，如下所示

 $ this -> client =  MgKurentoClient KurentoClient:: create ( $ this -> wsUrl , $ this -> loop , $ this -> logger , function ( $ client ){
    $ this -> client -> createMediaPipeline ( function ( $ pipeline , $ success , $ data ){
        $ webRtcEndpoint = new  MgKurentoClient  MediaObject ( $ pipeline );
        $ webRtcEndpoint -> remoteCreate ( ' WebRtcEndpoint ' , function ( $ webRtcEndpoint , $ success , $ data ){
            $ webRtcEndpoint -> connect ( $ webRtcEndpoint , function ( $ success , $ data ) use ( $ webRtcEndpoint ){
                $ webRtcEndpoint -> remoteInvoke ( ' processOffer ' , array ( ' offer ' => $ this -> offer ), function ( $ success , $ data ){
                    echo $ data [ ' value ' ];
                    //we don't need the loop anymore , we're exiting now
                    $ this -> loop -> stop ();
                });
            });
        });
    });    
});
$ this -> loop -> run ();

安裝範例
