• How can I fix video processing and 500 Error - (Laravel, FFmpeg)

  19 juillet 2019, par San Martín Figueroa Pablo

  I’m setting up a new website with Laravel for uploading videos...
  I have read all the possible solutions but none of them help me to solve the issue...

  This is my issue : When I upload a small file (<10mb) the web works fine, the video get uploaded and the video get converted, the dashboard shows the converted videos---

  When I try to upload a large file, the file get uploaded, the video get converted with a green frame on it (really uggly) and the site goes to a 500 server error...

  I’m using Laravel Jobs to do the conversion.

  My Controller code :

      <?php
  
  
  
      namespace App\Http\Controllers;
  
  
  
      use Illuminate\Http\Request;
  
      use Illuminate\Support\Facades\DB;
  
      use Illuminate\Support\Facades\Storage;
  
      use Symfony\Component\HttpFoundation\Response;
  
      use Carbon;
  
      use Closure;
  
      use App\Jobs\ConvertVideoForPreview;
  
      use FFMpeg\FFProbe;
  
      use FFMpeg\Coordinate\Dimension;
  
      use FFMpeg\Format\Video\X264;
  
      use Pawlox\VideoThumbnail\Facade\VideoThumbnail;
  
      use Pbmedia\LaravelFFMpeg\FFMpegFacade as FFMpeg;
  
      use Illuminate\Contracts\Filesystem\Filesystem;
  
  
  
  
  
      use App\Video;
  
  
  
      class VideoController extends Controller
  
      {
  
      public function createVideo(){
  
          return view('video.createVideo');   
  
      }
  
      public function saveVideo(Request $request){
  
  
  
  
  
          set_time_limit(0);
  
          ini_set('memory_limit', '1024M');
  
  
  
          //Validar Formulario
  
  
  
          $validatedData = $this -> validate($request, [
  
  
  
              'title' => 'required',
  
              'description' => 'required',
  
              'palabras' => 'required',
  
              'video' => 'mimetypes:video/mp4,video/quicktime'
  
  
  
  
  
          ]);
  
  
  
          $video = new Video();
  
          $user = \Auth::user();
  
          $video -> user_id = $user->id;
  
          $video -> title = $request -> input('title');
  
          $video -> description = $request -> input('description');
  
          $video -> palabras = $request -> input('palabras');
  
  
  
  
  
  
  
          $video_file = $request -> file('video');
  
  
  
          if($video_file){
  
  
  
          $video_path = 'original'.'_'.$video_file ->                                 
  
          getClientOriginalName();
  
          Storage::disk('videos')-> put($video_path, 
  
          \File::get($video_file));
  
  
  
          $videoUrl = storage_path('app/videos/').$video_path;
  
          $storageUrl = storage_path('app/thumbs/');
  
          $fileName = 'thumb'.'_'.time().'.jpg';
  
          $second = 2;
  
  
  
          VideoThumbnail::createThumbnail($videoUrl, $storageUrl,     
  
          $fileName, $second, $width = 640, $height = 480);
  
  
  
          $video -> preview = $fileName;
  
          $video -> video_path = $video_path;
  
  
  
        }
  
          $video -> save();
  
  
  
          ConvertVideoForPreview::dispatch($video);
  
  
  
          return redirect() -> route('home')
  
                            -> with (array(
  
              'message' => 'El video se ha enviado con exito'));
  
        }
  
  
  
          public function getImage($filename){
  
  
  
              $file = Storage::disk('thumbs') -> get($filename);
  
              return new Response($file, 200);
  
        }
  
  
  
          public function getVideo($filename){
  
  
  
              $file = Storage::disk('converted_videos') ->   
  
          get($filename);
  
              return new Response($file, 200);
  
        }
  
  
  
        }

  This is my ConvertVideo Job :

      <?php
  
  
  
       namespace App\Jobs;
  
  
  
       use App\Video;
  
  
  
       use Carbon\Carbon;
  
       use FFMpeg;
  
       use FFMpeg\Format\Video\X264;
  
  
  
       use Illuminate\Http\Request;
  
       use Illuminate\Bus\Queueable;
  
       use Illuminate\Queue\SerializesModels;
  
       use Illuminate\Queue\InteractsWithQueue;
  
       use Illuminate\Contracts\Queue\ShouldQueue;
  
       use Illuminate\Foundation\Bus\Dispatchable;
  
  
  
       class ConvertVideoForPreview implements ShouldQueue
  
  
  
          {
  
            use Dispatchable, InteractsWithQueue, Queueable, 
  
            SerializesModels;
  
  
  
            public $video;
  
  
  
  
  
            public function __construct(Video $video)
  
           {
  
               $this -> video = $video;
  
           }
  
            public function handle()
  
           {
  
  
  
            $converted_name= 'preview'.'-'.$this -> video -> 
  
            video_path.'.mp4';
  
  
  
            FFMpeg::open('videos/'.$this -> video -> video_path)
  
  
  
                          -> export()
  
                  -> inFormat(new \FFMpeg\Format\Video\X264)
  
                      -> save('converted_videos/'.$converted_name); 
  
  
  
              $this -> video -> update([
  
              'video_preview' => $converted_name,
  
              'processed' => true
  
               ]);
  
        }
  
       }

  One of my goals is to upload large video files (<=4GB), show a uploading process bar and a encoding process bar during the video upload.

  I getting this error :

   [core:error] [pid 14787:tid 139975366489856] [client 
  
    201.188.26.12:51022] Script timed out before returning headers: 
  
    index.php, 

  It’s happend when the video es proccesing and the redirect to home dashboard it’s call...

  The FFMPEG works :

  [2019-07-19 17:20:41] local.INFO: ffprobe executed command successfully  
  
  [2019-07-19 17:21:52] local.INFO: ffmpeg executed command successfully  
  
  [2019-07-19 17:21:52] local.INFO: ffmpeg running command '/usr/local/bin/ffmpeg' '-y' '-i' '/home/tribus/public_html/storage/app/videos/original_Sequence 01.mov' '-threads' '12' '-vcodec' 'libx264' '-acodec' 'libfaac' '-b:v' '1000k' '-refs' '6' '-coder' '1' '-sc_threshold' '40' '-flags' '+loop' '-me_range' '16' '-subq' '7' '-i_qfactor' '0.71' '-qcomp' '0.6' '-qdiff' '4' '-trellis' '1' '-b:a' '128k' '-pass' '2' '-passlogfile' '/tmp/ffmpeg-passes5d31fbe9010e6ldt9s/pass-5d31fbe90152d' '/home/tribus/public_html/storage/app/converted_videos/preview-original_Sequence 01.mov.mp4'

  I have tried : Change all the memory and file size in PHP.ini, Nginx, Apache... (Probably I’m missing one)...

  Changed timeouts too.

  My environment : VPS 4GB 50GB, APACHE 2.4, PHP7.3, MySql MariaDB, WebServer : Apache-Nginx, Laravel 5.8.

  Can anyone help me to reach this ?...

  This is how the large video looks after converted and show 500 error in the browser :
  Error video processed

• Video transcoding during stream

  31 juillet 2017, par Wajahat

  I am trying to setup a testbed that will be used for experimentation, and I have deployed some VMs over Openstack and the setup looks like this currently :
  
  The far right machine is running Apache2 server and video is hosted in /var/www/html/videos folder. VNF1 and VNF2 machines are acting as intermediate routers with static routes configured to route traffic to Apache server machine.

  The client machine runs VLC player to stream video on-demand from the server over HTTP like this :

  vlc http://10.10.2.7/videos/bunny.mp4

  Now, I want to be able to do dynamic transcoding of video while it is being streamed, but I don’t want to do transcoding at server side (for experiment’s purpose the server is not in our control) neither at client side but somewhere in the middle machines (VNF1 for example) so that it is transparent to client.
  Basically, I want to implement video transcoder as a network function.

  I have found FFmpeg which I think should be able to get this done, ffmpeg-server for example allows streaming over HTTP, but I am not exactly sure how to use it for transcoding video traffic ?
