Question

我正在尝试使用mediaelement.js加载来自php的视频，但它无效..它显示“下载文件”

<video src="http://localhost/readmp4.php?id=111" width="640" height="360" id="player2" controls="controls">
<source type="video/mp4" src="http://localhost/readmp4.php?id=111" />
</video>
<script>
$('video').mediaelementplayer({});
</script>

Answer 1

我花了1.5小时来解决为什么mediaelement没有播放从php返回的音频文件。 darleys的建议有效，但是添加type =“audio / mpeg”也使它有效。

<audio src="stream.php?file=<?php echo urlencode($abs_file);?>" type="audio/mpeg" />

Answer 2

确保将mp4伪装成路径而不是php请求网址例如<video src=/junk/junk.mp4> instead of <video src=video.php?name=junk>
执行到php文件的htaccess路由，当用户请求一个路径路由到一个php文件，该文件将读取位置中保护的视频文件。例如......

RewriteRule ^ junk /(.*)/preview.php?media=$1 [QSA，L]

现在在php中，一定要满足safari（ipad / iphone）的要求......

<?php
class VideoGroup1 {
   public function preview() { 
       $id = substr($_REQUEST['media'],0,strrpos($_REQUEST['media'],"."));
       $thisMedia = Pillar_Manage_Media::fetchMedia($id);
       //echo Foundry_Useful::unsealit($thisMedia['path']).$thisMedia['mediaid'];
       $file = Foundry_Useful::unsealit($thisMedia['path']).$thisMedia['mediaid'].".mp4";
       $filesize = filesize($file);

       $offset = 0;
       $length = $filesize;

       if ( isset($_SERVER['HTTP_RANGE']) ) {


           $partialContent = true;


           preg_match('/bytes=(\d+)-(\d+)?/', $_SERVER['HTTP_RANGE'], $matches);

           $offset = intval($matches[1]);
           $length = intval($matches[2]) - $offset;
       } else {
           $partialContent = false;
       }

       $file = fopen($file, 'r');


       fseek($file, $offset);

       $data = fread($file, $length);

       fclose($file);

       if ( $partialContent ) {


           header('HTTP/1.1 206 Partial Content');

           header('Content-Range: bytes ' . $offset . '-' . ($offset + $length) . '/' . $filesize);
       }


       header('Content-Type: video/mp4');
       header('Content-Length: ' . $filesize);
       header('Content-Disposition: attachment; filename="' . $file . '"');
       header('Accept-Ranges: bytes');

       print($data);

   }//End Function preview


}//END Class VideoGroup1
