  Some months ago it worked perfectly. I installed also the new release of ffmpeg, but the result is the same.

• MySql stops running in combination with Laravel Queue, Supervisor, and FFMPEg

  13 juin 2014, par egekhter

  After setting up queue listener to process uploaded videos with FFMPEG, I’ve come back to the server several times to find that MySql has stopped running. I checked drive space and it’s about 77% used (43G out of 60G).

  Here’s my code in case it’s useful :

  public function fire($job, $data)
  
  {
  
  $data = json_decode($data['transcoding_message'], true);
  
  $output_directory = '/home/ubuntu/transcodes/';
  
  $amazon_array = array();
  
  
  
  $s3 = AWS::get('s3');
  
  
  
  
  
      //execute main transcoding thread
  
  
  
      $cmd = 'sudo ffmpeg -i ' . $data['temp_file_url'] . ' -y -vcodec libx264 -tune zerolatency -movflags faststart -crf 20 -profile:v main -level:v 3.1 -acodec libfdk_aac -b:a 256k ' . $output_directory. $data['temp_file_key'] . '_HQ.mp4 -vcodec libx264 -s ' . $sq_width . 'x' . $sq_height . ' -tune zerolatency -movflags faststart -crf 25 -profile:v main -level:v 3.1 -acodec libfdk_aac -b:a 256k ' . $output_directory. $data['temp_file_key'] . '_SQ.mp4 -ss ' . $seek_half . ' -f image2 -vf scale=iw/2:-1 -vframes 1 ' . $output_directory. $data['temp_file_key'] . '_thumb.jpg';
  
  
  
      exec($cmd." 2>&1", $out, $ret);
  
  
  
  
  
      if ($ret)
  
      {
  
  
  
          Log::error($cmd);
  
          echo 'Processing error' . PHP_EOL;
  
          //there was a problem
  
          return;
  
      }
  
  
  
      else
  
      {
  
          //setup file urls
  
      echo 'about to move files';
  
  
  
      $hq_url = $this->bucket_root . $data['user_id'] . '/' . $data['temp_file_key'] . '_HQ.mp4';
  
      $sq_url = $this->bucket_root . $data['user_id'] . '/' . $data['temp_file_key'] . '_SQ.mp4';;
  
      $thumb_url = $this->bucket_root . $data['user_id'] . '/' . $data['temp_file_key'] . '_thumb.jpg';
  
  
  
      $amazon_array['video_hq_url'] = $data['temp_file_key'] . '_HQ.mp4';
  
      $amazon_array['video_sq_url'] = $data['temp_file_key'] . '_SQ.mp4';
  
      $amazon_array['video_thumb_url'] = $data['temp_file_key'] . '_thumb.jpg';
  
  
  
              //copy from temp to permanent
  
  
  
      foreach ($amazon_array as $k => $f)
  
      {
  
          $uploader = UploadBuilder::newInstance()
  
              ->setClient($s3)
  
              ->setSource($output_directory.$f)

              'multipart_upload.after_part_upload',
  
              function($event) use ($f) {
  
                  // Do whatever you want
  
              }
  
          );
  
  
  
          try {
  
              $uploader->upload();
  
              echo "{$k} => Upload complete.\n" . PHP_EOL;
  
  
  
              DB::table('items')->where('id', $data['item_id'])->update(array($k => $this->bucket_root. $data['user_id'] . '/' .$f, 'deleted_at' => NULL));
  
              //delete local
  
  
  
              unlink($output_directory.$f);
  
  
  
              unset($uploader);
  
          } catch (MultipartUploadException $e) {
  
              $uploader->abort();
  
              echo "{$k} => Upload failed.\n" . PHP_EOL;
  
              continue;

              )
  
          );
  
          echo $data['temp_file_url'] . '=>' . " deleted from temp bucket.\n" . PHP_EOL;
  
          DB::connection('mysql3')->table('video_processing')->where('id', $data['id'])->update(array('deleted_at' => \Carbon\Carbon::now()));
  
  
  
      }
  
          $job->delete();
  
  
  
          // end of processing uploaded video
  
          }
  
  
  
  
  
      else
  
      {
  
          return;
  
      }

  Any ideas as to why MySql would die like that ?

  ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (111)

  Edit : I wanted to add that the php artisan queue:listen command is being triggered via Supervisor and that I have 4 running concurrent processes.
