php - 播放视频 - 服务器配置不正确 - 12939

Question

我在服务器端有一个带有 laravel (lumen) 的 ios 应用程序。我正在尝试在应用程序中播放服务器中的视频。

我正在使用播放器播放带有直接链接(例如 vine 视频链接)的视频，但是当我在本地服务器上保存相同的 vine 视频时，应用程序不播放该视频。事实上，当我用我的 api 路由尝试播放视频时，令人惊讶的是它在 Chrome 上播放了视频!但是在应用程序端，我收到错误:

The server is not correctly configured - 12939

(请注意，如果我将相同的 mp4 文件复制到 xCode 项目中，将其添加到“复制捆绑资源”，并尝试使用 fileWithPath，它会起作用。所以我相信这肯定是由服务器引起的，而不是视频文件/编解码器。)

我的路线: $app->get('/player/{filename}', 'PlayerController@show');

方法:

public function show ($filename)
{
  $this->playVideo($filename, 'recordings');
}

public function playVideo($filename, $showType)
{
    if (file_exists("../uploads/" . $showType . "/" . $filename)) {
        $finfo = finfo_open(FILEINFO_MIME_TYPE);
        $type = finfo_file($finfo, "../uploads/" . $showType . "/" . $filename);


        header("Content-Type: " . $type);
        readfile("../uploads/" . $showType . "/" . $filename);
    }
}

回顾一下我的问题，视频正在 Chrome 上播放但收到“12939”-移动应用程序上的“服务器配置不正确”。

编辑:

我尝试按照 Apple Documentations 中的说明使用它:

curl --range 0-99 http://myapi.dev/test.mp4 -o /dev/null

但是文档说:

"If the tool reports that it downloaded 100 bytes, the media server correctly handled the byte-range request. If it downloads the entire file, you may need to update the media server."

我收到了 100%，它为我下载了整个文件，所以我相信这是我的问题。但我不确定如何克服这个问题？我究竟做错了什么？我该怎么办？

总而言之，这解决了我的问题:

• 将其放入 VideoController:

  public function streamVideo() 
  {
    $video_path = 'somedirectory/somefile.mp4';
    $stream = new VideoStream($video_path);
    $stream->start(); 
  }
  

• 然后在 app > helpers > VideoStream.php 中创建了一个文件:

   <?php
   {
       private $path = "";
       private $stream = "";
       private $buffer = 102400;
       private $start  = -1;
       private $end    = -1;
       private $size   = 0;
  
       function __construct($filePath) 
       {
           $this->path = $filePath;
       }
  
       /**
        *      * Open stream
        *           */
       private function open()
       {
           if (!($this->stream = fopen($this->path, 'rb'))) {
               die('Could not open stream for reading');
           }
  
       }
  
       /**

       {
           ob_get_clean();
           header("Content-Type: video/mp4");

           header("Expires: ".gmdate('D, d M Y H:i:s', time()+2592000) . ' GMT');
           header("Last-Modified: ".gmdate('D, d M Y H:i:s', @filemtime($this->path)) . ' GMT' );
           $this->start = 0;
           $this->size  = filesize($this->path);
           $this->end   = $this->size - 1;
           header("Accept-Ranges: 0-".$this->end);
  
           if (isset($_SERVER['HTTP_RANGE'])) {
  
               $c_start = $this->start;

                   header("Content-Range: bytes $this->start-$this->end/$this->size");
                   exit;
               }
               if ($range == '-') {
                   $c_start = $this->size - substr($range, 1);
               }else{

               $this->end = $c_end;
               $length = $this->end - $this->start + 1;
