Tokbox one to one video calling

Question

I am working on Tokbox video calling process. Now I am using the sample kit of Tokbox which is working properly but it is showing me all active user video.

but I need one user can video calling to another user.

I mean I need one to one video calling process. Is It possible in Tokbox. So please help to solve out it.

This is My code

use Slim\Slim;
use Gregwar\Cache\Cache;
use OpenTok\OpenTok;

if(!empty($userid))
{
$autoloader = __DIR__.'/../../../component/tokbox/vendor/autoload.php'; 
if (!file_exists($autoloader)) {
  die('You must run `composer install` in the sample app directory');
}

require($autoloader);



// PHP CLI webserver compatibility, serving static files
$filename = __DIR__.preg_replace('#(\?.*)$#', '', $_SERVER['REQUEST_URI']);
if (php_sapi_name() === 'cli-server' && is_file($filename)) {
    return false;
}


// Initialize Slim application
$app = new Slim(array(
    'templates.path' => __DIR__
));

// Intialize a cache, store it in the app container
$app->container->singleton('cache', function() {
    return new Cache;
});

// Initialize OpenTok instance, store it in the app contianer
$app->container->singleton('opentok', function () {
    return new OpenTok('***', '****');
});
// Store the API Key in the app container
$app->apiKey = '45833942';
$id=$this->uri->segment('3');
$urlname=$this->uri->segment('4');
// Configure routes
$app->get('/home/livechat/'.$id.'/'.$urlname.'/', function () use ($app) {

    // If a sessionId has already been created, retrieve it from the cache
    $sessionId = $app->cache->getOrCreate('sessionId', array(), function() use ($app) {
        // If the sessionId hasn't been created, create it now and store it
        $session = $app->opentok->createSession();
        return $session->getSessionId();
    });

    // Generate a fresh token for this client
    $token = $app->opentok->generateToken($sessionId);

/*$this->db->select('activemember');
$this->db->from('pshy_videocat');
$psychics=$this->db->get();
$totaluseractive= $psychics->row();
$totalactivevideouser=$totaluseractive->activemember;*/

Here is a sample code. I've not used SLIM for this. But this can be done with Slim also. I've executed the script 5 times & each time I got a unique Session-Id.

Session Id Received -

Session Id Got : 1_MX40NTgzMzk0Mn5-MTQ5NDMyMzQ0NzU0NH5KNk9Gcy9FSktPSlUwdldUbURwazJ0Umd-QX4
Session Id Got : 2_MX40NTgzMzk0Mn5-MTQ5NDMyMzQ3ODMzM35rWWU5NDV1ZjZPMGhLc3pCS3pRSERJY0h-QX4
Session Id Got : 1_MX40NTgzMzk0Mn5-MTQ5NDMyMzQ5NTcwOX5kc0Q3NDBjQSthOWJaMEk1eUllU3dCY0t-QX4
Session Id Got : 2_MX40NTgzMzk0Mn5-MTQ5NDMyMzUwNzExOH5NMEZuZWRyejBZYnZRVk1zSEczNldocmV-QX4
Session Id Got : 1_MX40NTgzMzk0Mn5-MTQ5NDMyMzUxNzE3NH5Yc0hyMUlacmFqK25pVzhXNDI5NTV6eDB-QX4

Vanilla PHP Script -

<?php
error_reporting(E_ALL);
ini_set('display_errors', '1');

require 'vendor/autoload.php';
use OpenTok\OpenTok;

$apiKey = '45833942';
$apiSecret = '9727d4ae20e8695a8f787bc58c0b4a9ebf6aae6e';
$opentok = new OpenTok($apiKey, $apiSecret);

use OpenTok\MediaMode;
use OpenTok\ArchiveMode;


// An automatically archived session:
$sessionOptions = array(
    'archiveMode' => ArchiveMode::ALWAYS,
    'mediaMode' => MediaMode::ROUTED
);
$session = $opentok->createSession($sessionOptions);


// Store this sessionId in the database for later use
$sessionId = $session->getSessionId();


echo "Session Id Got : $sessionId";

SLIM Version -

<?php
error_reporting(E_ALL);
ini_set('display_errors', '1');

use \Psr\Http\Message\ServerRequestInterface as Request;
use \Psr\Http\Message\ResponseInterface as Response;
use OpenTok\OpenTok;
use OpenTok\MediaMode;
use OpenTok\ArchiveMode;

require 'vendor/autoload.php';

$app = new \Slim\App;

$container = $app->getContainer();

$container['opentok'] = function ($c) {
    $apiKey = '45833942';
    $apiSecret = '9727d4ae20e8695a8f787bc58c0b4a9ebf6aae6e';

    $opentok = new OpenTok($apiKey, $apiSecret);
    return $opentok;
};


$app->get('/', function (Request $request, Response $response) {
    // An automatically archived session:
    $sessionOptions = array(
        'archiveMode' => ArchiveMode::ALWAYS,
        'mediaMode' => MediaMode::ROUTED
    );
    $session = $this->opentok->createSession($sessionOptions);

    // Store this sessionId in the database for later use
    $sessionId = $session->getSessionId();

    $response->getBody()->write("Session Id Got : $sessionId");
    return $response;
});

$app->run();

Hope, it'll help you.

Looks like you have based your code on the OpenTok Hello World PHP sample. This sample is written to support a single session only, for demonstration purposes. Your issue here is that you are retrieving the same key (sessionId) from cache every time, which is what the sample does.

You are close. The simplest way to extend this sample to multiple sessions is to store your new session IDs in the cache as different keys. You need to change your code to use different key for storing and retrieving session ID. So, you can change the cache retrieval logic from:

<?php
$sessionId = $app->cache->getOrCreate('sessionId', array(), function() use ($app) {
  # ...
}
?>

to something like:

<?php
# Here we add `$id` from the URI segment to create a unique key
# Notice the change in the key name to `'session' . $id'`
$sessionId = $app->cache->getOrCreate('session' . $id, array(), function() use ($app) {
  # ...
}
?>

At the simplest, your code needs to map your application's live chat ID to an OpenTok session internally. Everytime you request for a new livechat ID, it will create a new OpenTok session and store the new OpenTok session ID internally for that livechat ID.

So, you should have two different sessions if you request:

• /home/livechat/foo/bar
• /home/livechat/baz/bar

Bonus

A quick tip on creating OpenTok sessions: This is all you need to create a new session using OpenTok PHP SDK:

<?php
use OpenTok\OpenTok;
$apiObj = new OpenTok($API_KEY, $API_SECRET);

# This function creates an OpenTok session and returns a new session ID
function createOTSession() {
  $session = $apiObj->createSession(array('mediaMode' => MediaMode::ROUTED));
  return $session->getSessionId();
}
?>

Everytime you call $apiObj->createSession(), it creates a new session and you can access the session id by calling getSessionId() on the returned object. If you have a function like createOTSession() above, you can call that function from a route that needs to creates new sessions.
