• Returning a success or failure from ffmpeg

  2 novembre 2017, par user3331834

  I have some code executed in PHP after meeting some criteria through if/then statements which looks something like this :

  if(in_array($ext,$video)&&($ext!=="mp4")){
  
      exec("ffmpeg -i ".$fileName.".".$ext." -s 640x360 ".$fileName.".mp4");
  
      /*
  
      if(successful){
  
          unlink($fileName.$ext);
  
          $status="Video entry approved. File converted.";
  
      }
  
      */
  
  }

  As you can see, the issue I’m having is trying to figure out what should go in place of if(successful). The point of this section of the code is to check the files extension against an array of known extensions that are in video format, and that aren’t already in the mp4 format. If it passes this check, ffmpeg should run and convert to mp4.

  So a few questions here. Firstly, how can I return a status to tell me if it is converting, succeeded, or failed ? Secondly, how can this be run asynchronously ? That is, if I wanted to convert multiple files, would I be able to do so ? Would I be able to limit ffmpeg to ensure it does not take up all of my server’s processing power and inadvertently bring the site to a grinding halt ?

  Or is there a better way to go about converting files than this ? I’m pretty sure my method must be crude.

  EDIT : In addition to this, how does one run ffmpeg in the background, so that the page can be closed, and/or another instance from the same page can be started up by the user for multiple simultaneous conversions ? Is it possible to include a real-time progress status of each conversion ?
