问题描述

我在服务器端有一个带有laravel(内腔)的ios应用程序.我正在尝试在服务器上播放应用程序中的视频.

I have an ios app with laravel (lumen) on the server side. I am trying to play the videos in the server, on application.

我使用的播放器播放具有直接链接(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,该应用程序不会播放该视频.实际上,当我使用api路由尝试视频时,令人惊讶的是它在Chrome上播放了视频!但是在应用程序端,我收到错误消息:

I am using a Player that plays videos with a direct link (e.g vine video link), however when I save the same vine video on my local server, the application doesn't play the video. In fact, when I try the video with my api route, surprisingly it plays the video on Chrome! But on the application end, I receive error:

((请注意,如果我将相同的mp4文件复制到xCode项目中,则将其添加到复制捆绑包资源"上,并尝试使用fileWithPath,它可以正常工作.因此,我相信它肯定是由服务器而不是服务器引起的) vidoo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,该视频正在Chrome上播放,但收到"12939"-移动应用上的服务器配置不正确".

To recap my problem, the video is playing on Chrome but receiving '12939' -'Server is not correctly configured' on the mobile app.

我尝试按照 Apple文档:

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

但是文档说:

我收到了100%,它为我下载了整个文件,所以我认为这是我的问题.但是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?

I received 100% and it downloaded the whole file for me, so I believe this is my problem. But I am not sure how to overcome this issue? What am I doing wrong? What should I do?

推荐答案

总而言之,这解决了我的问题:

  • 将其放置到VideoController:

  • Placed this to VideoController:

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

  • ,然后在app > helpers > VideoStream.php中创建文件:

  • and then created a file in app > helpers > VideoStream.php:

     <?php
     {
         private $path = "";
         private $stream = "";
         private $buffer = 102400;
         private $start  = -1;
         private $end    = -1;
         private $size   = 0;
    
         function __construct($filePath)
         {
             $this->path = $filePath;
         }
    
         /**

         private function open()
         {
             if (!($this->stream = fopen($this->path, 'rb'))) {
                 die('Could not open stream for reading');
             }
    
         }
