我的情况令我难过,所以我正在寻找任何可以得到的帮助。
我有一个iOS应用程序,它使用MPMoviePlayerViewController播放由Laravel 5站点管理的M4V视频文件。
如果直接从Laravel 5 / public文件夹下载视频文件,则视频文件播放效果非常好(在iOS中)。但是,我通常会从Laravel 5的Storage Facade存储和提供视频文件,因为我最终将使用S3和弹性转码器。
这适用于FireFox,包含QuickTime浏览器插件,VLC和其他流媒体视频客户端,但不适用于我们的iOS应用程序。
据我所知,MPMoviePlayerViewController对于如何格式化HTTP响应非常挑剔。我尝试过StreamedResponse,但这似乎没什么帮助。
因此,例如,直接从/ public文件夹中提取文件的以下URL可以在iOS上正常工作:
http://172.16.160.1/video_ae9a7da0efa211e4b115f73708c37d67.m4v
但是,如果我使用Laravel 5从存储器中提取该文件,iOS将无法播放。
http://172.16.160.1/api/getfile/f444b190ef5411e4b7068d1890d109e8/video_ae9a7da0efa211e4b115f73708c37d67.m4v
注意iOS没有提供任何有意义的错误,以帮助调试,但我很肯定它是如何通过Laravel 5进行HTTP响应。
这是我的路线:
Route::get('myapi/getfile/{filename?}', 'APIController@getfile')->where('filename', '(.*)');
这是我的控制器:
public function getfile($filename)
{
return $api = API::getfile($filename);
}
这是我的模特:
public static function getfile($filename) {
$file = Storage::disk('local')->get('Files/'.$filename);
return (new Response($file, 200))->header('Content-Type', 'video/mp4');
}
如果我遗漏了任何支持信息,请告诉我,我会发布。我的下一步可能是设置Wireshark测试平台,看看握手是什么样的。
提前感谢您的帮助。 : - )

我知道这是一篇老文章,但最终我需要将Laravel中的视频从S3流传输到需要HTTP_RANGE支持的播放器。我把它们放在一起(读了很多线程之后)。它应支持您在Laravel中定义的所有disks()。
我使用了下面的类,位于App / Http / Responses。要使用此类,请创建一个执行此操作的方法(这将是您的getFile方法的内容):
$filestream = new \App\Http\Responses\S3FileStream('file_path_and_name_within_bucket', 'disk_bucket_name');
return $filestream->output();
我只是将视频播放器的src指向实现该方法和成功的途径!
