播放视频 - 服务器配置不正确 - 12939
Playing Video - Server is not correctly configured - 12939
我在服务器端有一个 ios 应用程序 laravel (流明)。我正在尝试在应用程序中播放服务器中的视频。
我使用的播放器可以直接 link 播放视频(例如 vine 视频 link),但是当我在本地服务器上保存相同的 vine 视频时,应用程序不会播放视频。事实上,当我用我的 api 路线尝试播放视频时,令人惊讶的是它在 Chrome 上播放视频!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 'copy bundle resources',并尝试使用 fileWithPath,它会起作用。所以我相信肯定是服务器问题,不是vidoo问题file/codec.)
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”-
'Server is not correctly configured' 在移动应用上。

我尝试使用Apple Documentations中提到的这个:
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?
我 运行 遇到了一个与此类似的问题,但您的案例需要更多配置。
iOS 的 headers 需要使用 运行ge 请求适当设置,我能够为所有浏览器做到这一点的唯一方法是重新设计 this gist 到我需要的。
就我而言,我在 Laravel 中做了类似的事情:
//Video controller
...
public function showVideo($id){
$video = Video::find($id);
return $this->videoService->stream($video);
}
//Video Service
namespace App\Services\VideoService;
use Illuminate\Routing\ResponseFactory as Response;
use App\Models\Video;
class VideoService implements VideoServiceInterface
{
protected $response;
protected $video;
private $stream = "";
private $buffer = 102400;
private $start = -1;
private $end = -1;
private $size = 0;
public function __construct(Response $response){
$this->response = $response;
}
public function stream(Video $video){
$this->video = $video;
return $this->response->stream(function(){
$this->start();
});
}
//Implement the rest of the gist here, renaming where appropriate....
}
问题是,您使用的 Lumen 不支持响应工厂上的流方法。您需要做的是重新编写我给您的代码以包含 Symfony 的 StreamedResponse Object.
如果你看看如何 Laravel does it,你可能会做这样的事情:
//Video Service
namespace App\Services\VideoService;
use Symfony\Component\HttpFoundation\StreamedResponse as Response;
use App\Models\Video;
class VideoService implements VideoServiceInterface
{
protected $video;
private $stream = "";
private $buffer = 102400;
private $start = -1;
private $end = -1;
private $size = 0;
public function stream(Video $video){
$this->video = $video;
return new Response(function(){
$this->start();
});
}
//Implement the rest of the gist here, renaming where appropriate....
}
这不准确,开箱即用。但这应该为您提供注册自己的服务提供商所需的所有组件,并将其适当地应用于您自己的 use-case.
祝你好运。
总而言之,这解决了我的问题:
将其放入 VideoController:

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

回顾一下我的问题,视频正在 Chrome 上播放但收到“12939”- 'Server is not correctly configured' 在移动应用上。
