• ffmpeg converter php script not working as expected

  8 juillet 2012, par mintuz

  I have been looking into a php video converter method and have followed a tutorial on how to get one set up. It can read the source video file fine, my script shows an md5, fps rate, bit rate etc but it does not create the destination file. Any suggestions on why my code is not working.

  I have tried both system() ; and exec() ; commands, both do not work and safe_mode is off. I have also tried a more basic command

  "/usr/bin/ffmpeg -i /home/mintuz/video.avi /var/www/video.flv"

  This command however works through the terminal.

  <?php 
  
  define('FFMPEG_LIBRARY', '/usr/bin/ffmpeg');
  
  
  
  //ALTER STUFF HERE
  
  $srcFile = "/home/mintuz/video.avi"; //source file
  
  $destFile = "/var/www/video.flv"; //destination file
  
  
  
  
  
  if (strpos($srcFile, '.avi'))
  
  {
  
      $type = "avi";
  
      echo $type;
  
  }
  
  
  
  if (strpos($srcFile, '.mp4'))
  
  {
  
      $type = "mp4";
  
      echo $type;
  
  }
  
  
  
  if (strpos($srcFile, '.mov'))
  
  {
  
      $type = "mov";
  
      echo $type;
  
  }
  
  
  
  //-------------------------------------------------------------------------------------------------------------------
  
  // Create our FFMPEG-PHP class 
  
  $ffmpegObj = new ffmpeg_movie($srcFile); 
  
  
  
  // Save our needed variables 
  
  $srcWidth = makeMultipleTwo($ffmpegObj->getFrameWidth()); 
  
  echo "<br />".$srcWidth."<br />";
  
  
  
  $srcHeight = makeMultipleTwo($ffmpegObj->getFrameHeight()); 
  
  echo $srcHeight."<br />";
  
  
  
  $srcFPS = $ffmpegObj->getFrameRate();
  
  echo $srcFPS."<br />"; 
  
  
  
  $srcAB = intval($ffmpegObj->getAudioBitRate()/1000);  
  
  $srcAR = $ffmpegObj->getAudioSampleRate();  
  
  
  
  // Call our convert using exec() 
  
  $cmd = FFMPEG_LIBRARY." -i ".$srcFile." -ar ".$srcAR." -ab ".$srcAB." -f flv -s ".$srcWidth."x".$srcHeight." ".$destFile;
  
  system($cmd); 
  
  
  
  echo "Source File MD5 : ".md5_file($srcFile)."<br />";
  
  echo "Destination File MD5 : ".md5_file($destFile);
  
  
  
  // Make multiples function 
  
  function makeMultipleTwo ($value) 
  
  { 
  
      $sType = gettype($value/2); 
  
      if($sType == "integer") 
  
      { 
  
          return $value; 
  
      } else { 
  
          return ($value-1); 
  
      } 
  
  }

• grab_image is not working for HD videos ?

  21 février 2012, par user1222769

  I am using ffmpeg command for grab_image of converted videos which are in flv format. All videos images are created except for HD videos. The code which i have written is as follws. Thanks in advance.

  function grab_image($filename, $rootpath, $inputpath,$outputpath, $no_of_thumbs, $frame_number, $image_format, $width, $height)
  
  
  
  
  
      $_rootpath = $rootpath."\ffmpeg";
  
      // Media Size
  
      $size = $width."x".$height;
  
  
  
      // I am using static image, you can dynamic it with your own choice.
  
      $out=explode(".",$filename);
  
  
  
      $outfile = $out[0].".jpg";
  
  
  
      //$ffmpegcmd1="ffmpeg -i ".$inputpath."/".$filename." -ss 1.4 -vframes 1 -f image2 ". $outputpath."/".$outfile;
  
  
  
          // in local
  
  
  
             $ffmpegcmd1="D:/xampp/htdocs/abc/ffmpeg -i ".$inputpath."/".$filename." -r 1 -ss 1.4 -vframes 1 -f image2 ". $outputpath."/".$outfile;
  
      $ret = exec($ffmpegcmd1);
  
  
  
      // Execute this command using exec command or any other tool to grab image from converted flv file.
  
      return $ffmpegcmd1;
  
  }
  

• FFmpeg AVI recording for H264 @ 1fps not working

  27 février 2012, par Alam

  I am recording H.264 (640x480 @1fps 10seconds) in avi container using FFMPEG. When I play the recorded file in VLC, it plays only first frame and rest of the frames are not played. I am getting

  Is there something I am doing wrong ? Same code works perfectly for frame rate above 3
