Zencoder API PHP Library

Author: Michael Christopher Company: Zencoder - Online Video Encoder Version: 2.1.1 Date: 2012-08-02 Repository: http://github.com/zencoder/zencoder-php/

Parts of this library are based on http://github.com/twilio/twilio-php

For more details on v2 of the Zencoder API visit http://blog.zencoder.com/2012/01/05/announcing-zencoder-api-v2/

For more details on the Zencoder API requirements visit http://app.zencoder.com/docs/api

To start working with the library, create a new instance of the Services_Zencoder class, passing your API Key as the 1st parameter.

$zencoder = new Services_Zencoder('93h630j1dsyshjef620qlkavnmzui3');

Once you have created the object, you can use it to interact with the API. For full information, see the Documentation folder, but here is a quick overview of some of the functions that can be called:

$zencoder->accounts->create($array);
$zencoder->jobs->create($array);
$zencoder->jobs->progress($job_id);
$zencoder->inputs->details($input_id);
$zencoder->outputs->details($output_id);
$zencoder->notifications->parseIncoming();

Any errors will throw a Services_Zencoder_Exception. You can call getErrors() on an exception and it will return any errors received from the Zencoder API.

ENCODING JOB

The ZencoderJob object creates an encoding job using cURL to send JSON formatted parameters to Zencoder's encoding API.

Step 1

Visit the API builder in your account, and execute a successful encoding job.

Step 2

Copy the successful JSON string, starting with the first curly brace "{", and pass it as the parameters for a new ZencoderJob object. Execute the script on your server to test that it works.

Example

<pre>
<?php

// Make sure this points to a copy of Zencoder.php on the same server as this script.
require_once('Services/Zencoder.php');

try {
  // Initialize the Services_Zencoder class
  $zencoder = new Services_Zencoder('93h630j1dsyshjef620qlkavnmzui3');

  // New Encoding Job
  $encoding_job = $zencoder->jobs->create(
    array(
      "input" => "s3://bucket-name/file-name.avi",
      "outputs" => array(
        array(
          "label" => "web"
        )
      )
    )
  );

  // Success if we got here
  echo "w00t! \n\n";
  echo "Job ID: ".$encoding_job->id."\n";
  echo "Output ID: ".$encoding_job->outputs['web']->id."\n";
  // Store Job/Output IDs to update their status when notified or to check their progress.
} catch (Services_Zencoder_Exception $e) {
  // If were here, an error occured
  echo "Fail :(\n\n";
  echo "Errors:\n";
  foreach ($e->getErrors() as $error) echo $error."\n";
  echo "Full exception dump:\n\n";
  print_r($e);
}

echo "\nAll Job Attributes:\n";
var_dump($encoding_job);

?>
</pre>

Step 3

Modify the above script to meet your needs.
Your API Request History may come in handy.
You can revisit your API builder to add/update parameters of the JSON.

You can translate the JSON string into nested associative arrays so that you can dynamically change attributes like "input".
The previous JSON example would become:

$encoding_job = $zencoder->jobs->create(array(
  "input" => "s3://bucket-name/file-name.avi",
  "outputs" => array(
    array(
      "label" => "web"
    )
  )
));

NOTIFICATION HANDLING

The ZencoderOutputNotification class is used to capture and parse JSON data sent from Zencoder to your app when an output file has been completed.

Step 1

Create a script to receive notifications, and upload it to a location on your server that is publicly accessible.

Example

<?php

// Make sure this points to a copy of Zencoder.php on the same server as this script.
require_once('Services/Zencoder.php');

// Initialize the Services_Zencoder class
$zencoder = new Services_Zencoder('93h630j1dsyshjef620qlkavnmzui3');

// Catch notification
$notification = $zencoder->notifications->parseIncoming();

// Check output/job state
if($notification->job->outputs[0]->state == "finished") {
  echo "w00t!\n";

  // If you're encoding to multiple outputs and only care when all of the outputs are finished
  // you can check if the entire job is finished.
  if($notification->job->state == "finished") {
    echo "Dubble w00t!";
  }
} elseif ($notification->job->outputs[0]->state == "cancelled") {
  echo "Cancelled!\n";
} else {
  echo "Fail!\n";
  echo $notification->job->outputs[0]->error_message."\n";
  echo $notification->job->outputs[0]->error_link;
}

?>

Step 2

In the parameters for an encoding job, add the URL for your script to the notifications array of each output you want to be notified for. Then submit the job to test if it works.

You can view the results at:
https://app.zencoder.com/notifications

Example

...
"outputs" => array(
  array(
    "label" => "web",
    "notifications" => array("http://example.com.com/encoding/notification.php")
  ),
  array(
    "label" => "iPhone",
    "notifications" => array("http://example.com.com/encoding/notification.php")
  )
)
...

Step 3

Modify the above script to meet your needs.
Your notifications page will come in handy.
