• 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 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');

          $validatedData = $this -> validate($request, [

          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);
  
        }

              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

  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 :

• how to kill a thread which hang up and release resources [duplicate]

  15 octobre 2019, par DJI_lover

  This question already has an answer here :

  • How do I terminate a thread in C++11 ?
    
    5 answers
    

  I am doing some jobs in ubuntu with c++.I want to know how to kill a thread when function blocking in a thread and there is no timeout mechanism for this function. I want to force to kill the thread when function is blocking and release all the resources in the thread and then restart the thread.I can’t set a quit flag in thread because it nerver get there when function hang up.Could someone tell me the better way to do this ? Thanks !

  Code :

  static int encode_and_write_frame(AVCodecContext *codec_ctx, AVFormatContext *fmt_ctx, AVFrame *frame)
  
  {
  
      AVPacket pkt = {0};
  
      av_init_packet(&pkt);
  
      int ret = avcodec_send_frame(codec_ctx, frame);
  
      if (ret < 0)
  
      {
  
          fprintf(stderr, "Error sending frame to codec context!\n");
  
          return ret;
  
      }
  
      ret = avcodec_receive_packet(codec_ctx, &pkt);
  
      if (ret < 0)
  
      {
  
          fprintf(stderr, "Error receiving packet from codec context!\n" );
  
          return ret;
  
      }
  
      int ret1 = av_interleaved_write_frame(fmt_ctx, &pkt);
  
      av_packet_unref(&pkt);
  
      return ret1;
  
  }
  
  
  
  void thread_worker(){
  
      while(ros::ok()){
  
          encode_and_write_frame(param1,param2,param3);
  
          usleep(500000);
  
      }
  
  }
  
  
  
  thread t(&thread_worker);

  when the network situation is good, av_interleaved_write_frame() can return quickly,but when network was broken down, av_interleaved_write_frame() will hang forever, and I can’t set timeout for av_interleaved_write_frame so that I want to kill the blocking thread and restart it.
