• FFMPEG PHP enter command lines ?

  3 mai 2019, par Robert

  You will have to excuse me I have been spending the past 2 days reading through old FFMPEG posts for an answer but did little but confuse myself.
  It seems from what I read FFMPEG-PHP wrappers aren’t supported anymore ??? and to be honest they don’t seem like the proper way of learning how to incorporate it with PHP as there is a whole lot more help for command line FFMPEG usage and the FFMPEG-PHP wrapper usage looks nothing like the command line as far as I can tell.

  So I have 2 questions on using ffmpeg with PHP. So we are on the same page I posted a little info below.

  I downloaded FFMPEG static for windows 64bit.
  I then ran (in composer)

        $ composer require php-ffmpeg/php-ffmpeg

  in my vendor folder i have the following path.

      vendor\ffmpeg-20190429-ac551c5-win64-static\bin

  if I open the command prompt in that folder and type FFMPEG I get.

  So I’m pretty sure FFMPEG is installed which was my goal.

  Now on my PHP side here is where I am at, and I’m not sure how this works.

  1ST QUESTION. Do I need to save my $_POST files to the drive before manipulating them ? Or can I use the $file and $filep as is ? I don’t really want to store those files, only the output.

  My SLIM code.

   $app->post('/telestrator', function(Request $request, Response $response) 
  
   {
  
  
  
   $response = array();
  
  
  
   if (isset ($_POST['ID']) && ($_POST['position']) && $_FILES['video'] 
  
   ['error'] === UPLOAD_ERR_OK && $_FILES['image']['error'] === 
  
   UPLOAD_ERR_OK) {
  
  
  
   $file = $_FILES['video']['tmp_name'];
  
   $filep = $_FILES['image']['tmp_name'];
  
   $time = $_POST['position'];
  
   $position = msToTime($time);
  
   $filetime = round(microtime(true) * 1000);
  
   $outputfolder = 'teletemp/';
  
  
  
   $ID = $_POST['ID'];
  
  
  
   $tempvid = $ID . 'tempvid' . 'mp4';
  
   $finalvid = $ID  . $filetime . 'mp4';
  
  
  
  
  
   $ffmpegpath = "public/ffmpeg.exe";
  
  
  
  echo "Starting ffmpeg...\n\n";
  
  echo shell_exec("$ffmpegpath -loop 1 -i $filep -c:v libx264 -t 3 -pix_fmt 
  
  yuv420p \"$outputfolder.\" $tempvid /");
  
   echo shell_exec("$ffmpegpath -i $file -t $position -c copy 
  
  \"$outputfolder\" 
  
   small-1.mp4 -ss $position -codec copy \"$outputfolder\" small-2.mp4 ");
  
   echo shell_exec("$ffmpegpath -i small-1.mp4 -i $tempvid.mp4 -i small- 
  
  2.mp4 \ 
  
   -filter_complex \"[0:v:0][1:v:0][2:v:0]concat=n=3:v=1:a=1[outv]\" \ 
  
   -map \"[outv]\" $finalvid" );
  
   echo "Done.\n";
  
  
  
   $upload = new videouploads();
  
  
  
          $desc = 'telestrated video for ' . $ID . $filetime;
  
          $ID = $_POST['ID'];  
  
  
  
          if ($upload->saveVideoFile($finalvid, getFileExtension($finalvid), 
  
   $desc, $ID)) {
  
              $response['error'] = false;
  
              $response['message'] = 'File Uploaded Successfullly';
  
          }
  
       else {
  
          $response['error'] = true;
  
          $response['message'] = 'Required parameters are not available';
  
      }
  
      echo json_encode($response);
  
    } 
  
   });
  
  
  
   function getFileExtension($file)
  
   {
  
   $path_parts = pathinfo($file);
  
   return $path_parts['extension'];
  
   }
  
  
  
   function msToTime($duration) {
  
   $seconds = floor($duration / 1000);
  
   $minutes = floor($seconds / 60);
  
   $hours = floor($minutes / 60);
  
   $milliseconds = $duration % 1000;
  
   $seconds = $seconds % 60;
  
   $minutes = $minutes % 60;
  
  
  
   $format = '%02u:%02u:%02u.%03u';
  
   $time = sprintf($format, $hours, $minutes, $seconds, $milliseconds);
  
   return rtrim($time, '0');
  
  
  
   }

  so it’s not running here is my postman. How do I get it to actually run the FFMPEG.

   Starting ffmpeg...
  
  
  
   Done.

• Launch command from controller avoid loading page

  28 juin 2019, par JoakDA

  When I launch a command from a Symfony controller, the command is executed but the GET request does not finish.

  My command launchs a node.js script that receive rtsp frames transcoded from ffmpeg and broadcast it to a websocket.

  This is a Debian 9 server, running Symfony 4, PHP 7.3.5 and Apache2.

  This is my controller show action that calls the command :

      /**
  
       * Render view to show device details.
  
       * @param Request $request
  
       * @param $deviceid
  
       * @return Response
  
       * @Route("devices/show/{deviceid}", name="device_show", methods={"GET"})
  
       * @IsGranted("ROLE_OPERATOR")
  
       */
  
      public function showAction(Request $request, $deviceid)
  
      {
  
      try{
  
          //Find device to show from system
  
          $deviceToShow = $this->repository->find($deviceid);
  
  
  
          if ($deviceToShow) {
  
              $this->logger->debug('Show device: . Device has been found. Delete it... Data: ' . $deviceToShow->__toString());
  
  
  
              //Launch video streaming commands
  
              $command = new VideoServerCommand($this->entityManager, $this->logger, $this->getParameter('kernel.project_dir'));
  
              $input = new ArrayInput(array(
  
                  'secret' => str_replace(' ', '', $deviceToShow->getName()),
  
                  'http_port' => 8002,
  
                  'ws_port' => 8005
  
              ));
  
              $output = new BufferedOutput();
  
              $resultCode  = $command->run($input, $output);
  
  
  
              $content = $output->fetch();
  
  
  
              if ($resultCode === 0){
  
                  $this->logger->info('Call Video Server Command: Ok. Video Server started successfully. Console output: ' . $content);
  
              }else{
  
                  $this->logger->error('Call Video Server Command: Ko. Could not start video server. Console output: ' . $content);
  
              }
  
  
  
          }else{
  
              $message = $this->translator->trans('Device with identifier %deviceid% was not found.',
  
                  ['%deviceid%' => $deviceid]);
  
  
  
              $this->addFlash('error', $message);
  
  
  
              $this->logger->error('Show device: Ko. Device with identifier ' . $deviceid . ' was not found.');
  
          }
  
      }catch (Exception $exception) {
  
          $message = $this->translator->trans('Error while executing action. Error detail: %detail%.',
  
              ['%detail%' => $exception->getMessage()]);
  
  
  
          $this->addFlash(
  
              'error', $message
  
          );
  
  
  
          $this->logger->critical('Show device: Ko. Exception catched. Error detail: ' . $exception->getMessage());
  
      }
  
  
  
      $host = explode(':', $request->getUri());
  
  
  
      return $this->render('device/show.html.twig', array(
  
          'baseurl' => $host[1],
  
          'secret' => str_replace(' ', '', $deviceToShow->getName()),
  
          'device' => $deviceToShow,
  
      ));
  
      }

  And this is my command code that runs the node.js script

  protected function execute(InputInterface $input, OutputInterface $output)
  
      {
  
          try {
  
              $this->logger->info('Start web socket: Setup websocket server...');
  
              $this->io = new SymfonyStyle($input, $output);
  
              $now = new \DateTime();
  
              $this->io->title('Start websocket server ' . $now->format('d-m-Y G:i:s') . '...');
  
  
  
              //Get input parameters
  
              $secret = $input->getArgument('secret');
  
              $tcpPort = $input->getArgument('http_port');
  
              $wsPort = $input->getArgument('ws_port');
  
  
  
              $output->writeln([
  
                  'Video Server',// A line
  
                  '============',// Another line
  
                  'Starting Video Reception Socket...',// Empty line
  
              ]);
  
  
  
              //Call node websocket-relay.js
  
              $command = 'node ' . $this->path . '/assets/js/websocket-relay.js ' . $secret . ' ' . $tcpPort . ' ' . $wsPort;
  
              //Only want to execute for 60 seconds
  
              $nodeVideoRelay = new Process(exec($command));
  
              $nodeVideoRelay->setTimeout(60);
  
              $nodeVideoRelay->setIdleTimeout(60);
  
  
  
              try {
  
                  $nodeVideoRelay->run();
  
  
  
                  $this->logger->info('Start video streaming: OK. Video streaming successfully started...');
  
                  $this->io->success('Start video streaming: OK. Video streaming successfully started...');
  
                  $this->io->writeln($nodeVideoRelay->getOutput());
  
              } catch (ProcessTimedOutException $timedOutException) {
  
                  $nodeVideoRelay->stop(3, SIGINT);
  
                  $this->io->success('Start video streaming: Ok. Streaming finished.');
  
              }
  
              //}
  
          } catch (Exception $exception) {
  
              $this->logger->critical('Start video streaming: Ko. Exception catched. Error detail: ' . $exception->getMessage());
  
              $this->io->error('Start video streaming: Ko. Exception catched. Error detail: ' . $exception->getMessage());
  
          }
  
      }

  And the "websocket-relay.js" is an script got from https://github.com/phoboslab/jsmpeg/blob/master/websocket-relay.js

  The result is that the page is not loading. I have another command that process the RTSP stream using ffmpeg and send the date to a websocket.

  On the page that returns my controller action, it appears a canvas where the video will be rendered.

  I want to render the page as soon as possible and that the node.js script runs on background without blocking the main process.

  Thank you for helping me.
