Get direct link videos from Vimeo in PHP - php

Question

I want a direct link to videos from Vimeo with a PHP script.
I managed to find them manually, but my PHP script does not work.
Here is the initiative:
For example I took this video: http://vimeo.com/22439234
When you go on the page, Vimeo generates a signature associated with the current timestamp and this video. This information is stored in a JavaScript variable, around line 520 just after:
window.addEvent ('domready', function () {
Then when you click Play, the HTML5 player reads this variable and sends an HTTP request:
http:// player.vimeo.com/play_redirect?clip_id=37111719&sig={SIGNATURE}&time={TIMESTAMP}&quality=sd&codecs=H264,VP8,VP6&type=moogaloop_local&embed_location=
But it also works with:
http:// player.vimeo.com/play_redirect?clip_id=37111719&sig={SIGNATURE}&time={TIMESTAMP}&quality=sd
If this URL does not open with the IP address that opened http://vimeo.com/22439234, this returns the HTTP code 200 with an error message.
If this URL is opened with the correct IP address, the header "Location" redirects to link to the video file:
http://av.vimeo.com/XXX/XX/XXXX.mp4?aksessionid=XXXX&token=XXXXX_XXXXXXXXX
When I build this link http://player.vimeo.com/play_redirect?... manually ("right click"> "source code"> "line 520") it works.
But with PHP and regex it returns the HTTP code 200 with an error message.
Why ?
From my observations, Vimeo does not check the headers of the HTTP request for http:// player.vimeo.com/play_redirect?...
GET, HEAD, with cookies, without cookies, referrer etc. ... does not change.
With PHP, I use the function file_get_contents() and get_headers().
<?php
function getVimeo($id) {
$content = file_get_contents('http://vimeo.com/'.$id);
if (preg_match('#document\.getElementById\(\'player_(.+)\n#i', $content, $scriptBlock) == 0)
return 1;
preg_match('#"timestamp":([0-9]+)#i', $scriptBlock[1], $matches);
$timestamp = $matches[1];
preg_match('#"signature":"([a-z0-9]+)"#i', $scriptBlock[1], $matches);
$signature = $matches[1];
$url = 'http://player.vimeo.com/play_redirect?clip_id='.$id.'&sig='.$signature.'&time='.$timestamp.'&quality=sd';
print_r(get_headers($url, 1));
}

The algorithm looks like this:
Input data: vimeoUrl.
content = getRemoteContent(vimeoUrl).
Parse content to find and extract the value from data-config-url
attribute.
Navigate to data-config-url and load the content as JSON Object:
$video = json_decode($this->getRemoteContent($video->getAttribute('data-config-url')));
Return $video->request->files->h264->sd->url — this will return a
direct link for SD quality video.
Here is my simple class, that working for this moment.
class VideoController
{
/**
* #var array Vimeo video quality priority
*/
public $vimeoQualityPrioritet = array('sd', 'hd', 'mobile');
/**
* #var string Vimeo video codec priority
*/
public $vimeoVideoCodec = 'h264';
/**
* Get direct URL to Vimeo video file
*
* #param string $url to video on Vimeo
* #return string file URL
*/
public function getVimeoDirectUrl($url)
{
$result = '';
$videoInfo = $this->getVimeoVideoInfo($url);
if ($videoInfo && $videoObject = $this->getVimeoQualityVideo($videoInfo->request->files))
{
$result = $videoObject->url;
}
return $result;
}
/**
* Get Vimeo video info
*
* #param string $url to video on Vimeo
* #return \stdClass|null result
*/
public function getVimeoVideoInfo($url)
{
$videoInfo = null;
$page = $this->getRemoteContent($url);
$dom = new \DOMDocument("1.0", "utf-8");
libxml_use_internal_errors(true);
$dom->loadHTML('<?xml version="1.0" encoding="UTF-8"?>' . "\n" . $page);
$xPath = new \DOMXpath($dom);
$video = $xPath->query('//div[#data-config-url]');
if ($video)
{
$videoObj = json_decode($this->getRemoteContent($video->item(0)->getAttribute('data-config-url')));
if (!property_exists($videoObj, 'message'))
{
$videoInfo = $videoObj;
}
}
return $videoInfo;
}
/**
* Get vimeo video object
*
* #param stdClass $files object of Vimeo files
* #return stdClass Video file object
*/
public function getVimeoQualityVideo($files)
{
$video = null;
if (!property_exists($files, $this->vimeoVideoCodec) && count($files->codecs))
{
$this->vimeoVideoCodec = array_shift($files->codecs);
}
$codecFiles = $files->{$this->vimeoVideoCodec};
foreach ($this->vimeoQualityPrioritet as $quality)
{
if (property_exists($codecFiles, $quality))
{
$video = $codecFiles->{$quality};
break;
}
}
if (!$video)
{
foreach (get_object_vars($codecFiles) as $file)
{
$video = $file;
break;
}
}
return $video;
}
/**
* Get remote content by URL
*
* #param string $url remote page URL
* #return string result content
*/
public function getRemoteContent($url)
{
$ch = curl_init();
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
curl_setopt($ch, CURLOPT_TIMEOUT, 20);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_MAXREDIRS, 10);
curl_setopt($ch, CURLOPT_USERAGENT, 'spider');
$content = curl_exec($ch);
curl_close($ch);
return $content;
}
}
Using:
$video = new VideoController;
var_dump($video->getVimeoDirectUrl('http://vimeo.com/90747156'));

Try add a valid user-agent to headers for an each request.
For this you must use cURL or HttpRequest instead file_get_contents().
After such manipulations I got a working link for downloading the video file.
Here my code:
function getVimeo($id) {
// get page with a player
$queryResult = httpQuery('http://vimeo.com/' . $id);
$content = $queryResult['content'];
if (preg_match('#document\.getElementById\(\'player_(.+)\n#i', $content, $scriptBlock) == 0)
return 1;
preg_match('#"timestamp":([0-9]+)#i', $scriptBlock[1], $matches);
$timestamp = $matches[1];
preg_match('#"signature":"([a-z0-9]+)"#i', $scriptBlock[1], $matches);
$signature = $matches[1];
$url = 'http://player.vimeo.com/play_redirect?clip_id=' . $id . '&sig=' . $signature . '&time=' . $timestamp . '&quality=sd';
// make the request for getting a video url
#print_r(get_headers($url, 1));
$finalQuery = httpQuery($url);
return $finalQuery['redirect_url'];
}
// make queries via CURL
function httpQuery($url) {
$options = array(
CURLOPT_USERAGENT => 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/535.19 (KHTML, like Gecko) Ubuntu/12.04 Chromium/18.0.1025.168 Chrome/18.0.1025.168 Safari/535.19',
CURLOPT_RETURNTRANSFER => true,
);
$ch = curl_init($url);
curl_setopt_array($ch, $options);
$content = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);
$result = $info;
$result['content'] = $content;
return $result;
}
echo getVimeo(22439234);
