• FFMPEG running in Command Line but not PHP

  17 avril 2013, par Freeman

  I am using ffmpeg build for windows to make video thumbnails . The command works well in command line but not from PHP exec method. am using PHP 5.2.11

  Here is the command.

  "E:/Documents and Settings/x/WINDOWS/ffmpeg" -itsoffset -4 -v "E:/Program Files/Apache Software Foundation/Apache2.2/htdocs/bs/files/videogal/c08c3d20eeb9083ed033577bd154cba6.flv" -vcodec mjpeg -vframes 1 -an -f rawvideo -s 320x240 "E:/Program Files/Apache Software Foundation/Apache2.2/htdocs/bs/files/gallery/8ff43b72b932d2a34e7a6733672ad4d6.jpg" 2>&1

  Can somebody help. I checked the permissions they seem fine. GD is installed.

  The error msg is 'E:/Documents' is not recognized as an internal or external command, operable program or batch file

  Am using forward slashes in my paths except when escaping double quotes

  The PHP function

  function ExtractThumb($in, $out)
  
  {$path=dbconf::FFMPEG_PATH;
  
      $thumb_stdout;
  
      $errors;
  
      $retval = 0;
  
   echo $in;
  
      // Delete the file if it already exists
  
      if (file_exists($out)) { unlink($out); }
  
  
  
      // Use ffmpeg to generate a thumbnail from the movie
  
      $cmd = "$path -itsoffset -4 -i $in -vcodec mjpeg -vframes 1 -an -f rawvideo -s 320x240 $out 2>&1";
  
     echo $cmd;
  
  
  
     exec($cmd, $thumb_stdout, $retval);
  
  
  
      // Queue up the error for processing
  
      if ($retval != 0) { $errors[] = "FFMPEG thumbnail generation failed"; }
  
  
  
      if (!empty($thumb_stdout))
  
      {
  
          foreach ($thumb_stdout as $line)
  
          {
  
              echo $line . "\n";
  
          }
  
      }
  
  
  
      if (!empty($errors))
  
      {
  
          foreach ($errors as $error)
  
          {
  
              echo $error . "\n";
  
          }
  
      }
  
  }

  funny enough if I run without the $in and $out absolute path this is what I get

• ffmpeg to convert mov to flv

  27 octobre 2014, par jeet

  I’m trying to convert a mov video to flv, but keep getting these errors below.
  There are 2 commands I used, both are below.

  ffmpeg -y -i video.mov -deinterlace -acodec copy -r 25 -qmin 3 -qmax 6 video.flv

  Second command :

  ffmpeg -y -i video.mov -deinterlace -ar 44100 -r 25 -qmin 3 -qmax 6 video.flv

  Audio resampler only works with 16 bits per sample, patch welcome.

  1 more thing please :
  If I use this newer version of ffmpeg to create a video with the below command, I get a video with a very hazy display.
  It’s like a few black dots on a blank screen :

  ffmpeg -i img%d.png -i audio.wav -acodec copy output.mov

  what could be the reason for this display ?
