• Realtime ffmpeg shell output PHP

  26 septembre 2013, par matthew johnston

  Alright, I've been fighting this problem for a few days. Works fine on my local windows machine but, can't seem to get it to work on my CentOS server. My script grabs the duration of the video being converted and also grabs the current seconds it has processed inside of ffmpeg. However, it is only grabbing the "input file" of the ffmpeg output and stopping there. I have tried using both pipes (STDOUT [1] & STDERR [2]) for some reason ffmpeg likes to output on the STDERR pipe. Weird.

  $filename = "somefilename.tmp";
  
  $descriptor = array(
  
      0 => array("pipe", "r"),
  
      1 => array("pipe", "w"),
  
      2 => array("pipe", "w")
  
  );
  
  
  
  $ffmpeg = "ffmpeg -i /var/www/spotloader/videos/flipped/tmp/".$file."_comb.ts -vcodec mpeg2video -acodec pcm_s16le -pix_fmt yuv422p -vtag xdvb -b:v 13000k -r 30000/1001 /var/www/spotloader/videos/flipped/tmp/".$file.".mov";
  
  
  
  //open the process
  
  $process = proc_open($ffmpeg, $descriptor, $pipes, NULL, $_ENV);
  
  
  
  //if the process opened
  
  if ( is_resource( $process ) == true )
  
  {
  
      //get process status
  
      $procStatus = proc_get_status( $process );
  
  
  
      //if its running, let node know
  
      if ( $procStatus['running'] )
  
      {
  
          //nodejs socket, nothing wrong here
  
          $this->_sendSocket('converting', array('filename' => str_replace('.tmp', '', $file)));
  
      }
  
  
  
      //while the process is running
  
      while( $procStatus['running'] === true )
  
      {
  
          //there is output in the pipe
  
          if ( !feof( $pipes[1] ) )
  
          {
  
              //get the output
  
              $data = fgets($pipes[1], 128);
  
              //match the outputs duration and save it.
  
              if(preg_match('/Duration:\s([0-9]{2}:[0-9]{2}:[0-9]{2})/', $data, $matches)) 
  
              {
  
                  static $duration;
  
                  $duration = $this->_convertToSeconds($matches[1]);
  
              }
  
  
  
              //match the outputs current encoding time
  
              if(preg_match('/time=([0-9]{2}:[0-9]{2}:[0-9]{2})/', $data, $matches)) 
  
              {
  
                  //convert to seconds works fine, so it is not included.
  
                  $curTime = $this->_convertToSeconds($matches[1]);
  
                  //nodejs socket, nothing wrong here
  
                  $this->_sendSocket('update', array('percent' => round( ($curTime / $duration) * 100), 'filename' => str_replace('.tmp', '', $file)));
  
              }
  
          }
  
  
  
          //update process status
  
          $procStatus = proc_get_status( $process );
  
      }
  
  
  
      //nodejs socket, nothing wrong here
  
      $this->_sendSocket('converted', array('percent' => 100, 'filename' => str_replace('.tmp', '', $file)));
  
  }

  FFMPEG output I'm expecting the "time=00:00:00" towards the end is what I need to capture in realtime. This is taken by running the FFMPEG command directly in the shell.

  Any ideas ? What needs changing from the switch from Windows to CentOS ?

  EDIT :
  I got this to work using popen instead. It also reduced my code. If anyone else does have a solution go ahead and post it. Thanks !

• Using FFmpeg's (libavformat) RTP data structures via dynamic linking

  15 septembre 2011, par ericreeves

  I want to use the RTP data structures (e.g. RTPMuxContext in libavformat/rtpenc.h) provided by FFmpeg's libavformat however they don't seem to be available with the following install :

    libavfilter   2. 40. 0 /  2. 40. 0
  
    libswscale    2.  1. 0 /  2.  1. 0

  When I look in /usr/local/include, I see the libavformat directory however only a few files are there : avformat.h, avio.h, and version.h. Of course, when I try to include libavformat/rtpenc.h I get "error : libavformat/rtpenc.h : No such file or directory"

  I'd like to achieve this by dynamic linking to the FFmpeg libraries (for LGPL compliance, among other reasons), but it doesn't seem to be possible.

  Is there a parameter for the configure script that I'm missing, or a post-installation step that I've neglected ?
