• 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 :

• Getting media duration with ffprobe after decoding with FFmpeg

  23 août 2019, par Brad

  With ffprobe, it’s possible to get the duration of a media file :

  ffprobe -show_format 1064428_cityLights_HD_BG.mp4

  [FORMAT]
  …
  duration=10.010000

  However, ffprobe only digs into the container and doesn’t decode the media. For container formats that have no inherent duration, or for broken files that play but maybe weren’t finalized, the duration isn’t available :

  [FORMAT]
  …
  duration=N/A

  The recommended solution to this problem is to use FFmpeg to decode, and then parse STDERR.

  ffmpeg -i input.webm -f null -

  frame=206723 fps=1390 q=-0.0 Lsize=N/A time=00:57:28.87 bitrate=N/A speed=23.2x

  This works well enough, but if I’m integrating this into other programs and scripts, I have to assume that the output of FFmpeg isn’t going to change from version to version. It would be much more convenient if there were a way to use ffmpeg and ffprobe together, so that I could continue to utilize the JSON output of ffprobe.

  Is there some way to force ffmpeg to decode the media and pipe it to ffprobe in some way that allows ffprobe to include the duration in its output for these types of situations ?

  (Note : I know I can just have FFmpeg output a file, and then input that into ffprobe. For convenience, I’m curious if there’s an all-in-one solution, with a pipe or equivalent.)
