Getting Dailymotion Video (FLV) URL
22 Jan 2008Some developers asked me, if it is easy to get dailymotion flv URL? I thought, I would post how to do that.
If you know the dailymotion video-id, believe me it’s very simple to do that. In case, you don’t know how to get dailymotion video-id? Let me give you some hints, highlighted text is the video-id:-
- http://www.dailymotion.com/video/x44lvd_rates-of-exchange-like-a-renegade_music
- From RSS feed, either of following can be extracted:
- x44m3c
- http://www.dailymotion.com/swf/x44m3c” ..
Once you have video-id, you can use the following php-script (dailymotion.php.txt) to do either of two things:-
Get flv and thumbnail-url
http://yourserver/dailymotion.php?video_id=&redirect=false
- Returns: flv=thumbnail=
Redirect to dailymotion flv-url directly. It can be used directly from Netstream’s play () instance method
http://yourserver/dailymotion.php?video_id=&redirect=true
- Redirects (HTTP 303) to flv_url.
&redirect=true // Above invocation would return:- // flv=&thumbnail= // Example:- // URL: http://server/dailymotion.php?video_id=x44ls3&redirect=false // // Result:- // flv=http://www.dailymotion.com/get/15/320x240/flv/6933315.flv?key=69f63205c80b5b5d188a10e0b7656a421316ee3&previewURL=http://limelight-315.static.dailymotion.com/dyn/preview/320x240/6933315.jpg?20080122041 // // 2) For redirection to flv i.e. video_id to flv // http://server/dailymotion.php?video_id=&redirect=true // Above invocation would redirect to dailymotion flv URL if (isset ($_GET [‘video_id’]) == FALSE) { echo “video_id is required”; exit; } // Requires dailymotion video_id $url = ‘http://www.dailymotion.com/swf/’ . $_GET[‘video_id’]; if (isset($_GET[‘redirect’]) == FALSE) { $redirect = ‘true’; } //Start the Curl session $session = curl_init($url); curl_setopt($session, CURLOPT_HEADER, true); curl_setopt($session, CURLOPT_USERAGENT, ‘Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.9) Gecko/20071025 Firefox/2.0.0.9’); curl_setopt($session, CURLOPT_FOLLOWLOCATION, false); curl_setopt($session, CURLOPT_RETURNTRANSFER, true); // Make the call $response = curl_exec($session); $error = curl_error($session); $result = array( ‘header’ => ‘’, ‘body’ => ‘’, ‘curl_error’ => ‘’, ‘http_code’ => ‘’, ‘last_url’ => ‘’); if ( $error != “” ) { $result[‘curl_error’] = $error; } else { $header_size = curl_getinfo($session,CURLINFO_HEADER_SIZE); $result[‘header’] = substr($response, 0, $header_size); $result[‘body’] = substr( $response, $header_size ); $result[‘http_code’] = curl_getinfo($session, CURLINFO_HTTP_CODE); $result[‘last_url’] = curl_getinfo($session, CURLINFO_EFFECTIVE_URL); list($header, $result[‘header’]) = explode(“\n\n”, $result[‘header’], 2); $matches = array(); preg_match(‘/Location:(.*?)\n/’, $header, $matches); $urlInfo = parse_url(trim(array_pop($matches))); //$newUrl = $urlInfo[‘scheme’] . ‘://’ . $urlInfo[‘host’] . $urlInfo[‘path’] . ($urlInfo[‘query’]?’?’.$urlInfo[‘query’]:’’); parse_str($urlInfo[‘query’], $output); $flvURL = $output [‘url’]; $thumbnailURL = $output[‘previewURL’]; if ($redirect == “true”) { header (“Location: “. $flvURL, TRUE, 303); } else { echo sprintf (“flv=%s&thumbnail=%s”, $flvURL, $thumbnailURL); } } curl_close($session); ?>
Let me tell you, you can do the entire thing on client-side without using any server-side script, though logic remains same. Look at this post and learn what technique to use :-). Another hint, if you are consuming dailymotion rss-feed(s), you don’t need any php script to construct flv-url, you can just replace “80x40” text by “320x240” in media:content url.
As always, please look at the code, change, optimize and fix it to meet your requirements. I wrote it in ten minutes and just as a proof-of-concept, this is no way the best method and php-code can be much better.
