Transfer encode download

This code example uses the PEAR HTTP request lib.

It demonstrates how you can transfer a video, encode it in Flash format and get it back to your FTP in only one HTTP request.

<?php
require_once "HTTP/Request.php";

$video_url = "http://myhost.com/video.avi";

// We want to encode in Flash format
$format_id = "31";

// The encoded video will be uploaded to this FTP location
$ftp = "ftp://login:passwd@myhost.com/videos";

// You'll be notified when all the process is done
$ping_after_encode = "http://myhost.com/ping/success.php"; 

// You'll be notified if there is an error during the process.
$ping_if_error = "http://myhost.com/ping/error.php"; 

// Custom field to track your user, this is just an example
$my_site_user_id = $session->getCurrentUser->id;

// The video you'll show on your site
// Note that the class Video is not defined, it's just an example
// to interact with the database
$video = new Video(array("user_id" => $my_site_user_id, "status" => "unavailable"));
$video->save();
$my_site_video_id = $video->id;

$req =& new HTTP_Request("http://heywatch.com/download.xml");

// Authenticate via your HeyWatch login / password
$req->setBasicAuth("johndoe", "foo");

// It's a POST request
$req->setMethod(HTTP_REQUEST_METHOD_POST);

// Add all the needed parameters
$req->addPostData("url", $video_url);
$req->addPostData("format_id", $format_id);

// Force encoding after the download is complete
$req->addPostData("automatic_encode", "true");
$req->addPostData("ftp_directive", $ftp);
$req->addPostData("ping_url_after_encode", $ping_after_encode);
$req->addPostData("ping_url_if_error", $ping_if_error);

// Some custom fields to track your own objects
// You'll receive them in the ping after encode / ping if error
$req->addPostData("my_site_user_id", $my_site_user_id);
$req->addPostData("my_site_video_id", $my_site_video_id);

// Send the request
if (!PEAR::isError($req->sendRequest())) {
   echo $req->getResponseBody(); // XML response
}
?>

When all the process is done, you’ll receive the HTTP notification at:

/ping/success.php

<?php
  $filename = $_POST["filename"];

  // Custom fields are available in $_GET array
  $my_site_user_id = $_GET["my_site_user_id"];
  $video_id = $_GET["my_site_video_id"];

  // Map the FTP location and the HTTP server
  // ftp://myhost.com/videos => http: //myhost.com/videos
  $video_location = "http://myhost.com/videos/".$filename;
  $thumbnail_location = $video_location.".jpg";

  // Update the video to be available on your site
  $video = Video::find($video_id);
  $video->setStatus = "available";
  $video->setVideoLocation = $video_location;
  $video->setThumbnailLocation = $thumbnail_location;
  $video->save();
?>

If the process failed, you’ll receive the notification at:

/ping/error.php

<?php
  // Custom fields are available in $_GET array
  $my_site_user_id = $_GET["my_site_user_id"];
  $video_id = $_GET["my_site_video_id"];

  // Update your video to be flagged as error
  $video = Video::find($video_id);
  $video->setStatus = "error";
  $video->save();

  // Send a mail to the user about the error
?>
