• convert video to audio using ffmpeg

  5 mai 2024, par shakti goyal

  I'm trying to convert a video to mp3 using ffmpeg library but ffmpeg command is not working, it is returning the code 1

  


  Video conversion to MP3 failed with return code : 1

  


  try {
  final session = await FFmpegKit.execute('-i $videoFilePath -vn -ar 44100 -ac 2 -b:a 192k -f mp3 $audioFilePath');

  final returnCode = await session.getReturnCode();

  if (ReturnCode.isSuccess(returnCode)) {
    print('Video conversion to MP3 successful!');
  } else {
    print('Video conversion to MP3 failed with return code: $returnCode');
  }
} catch (e) {
  print('Error occurred during video conversion: $e');
}


  


  $videoFilePath - /Users/shaktigoyal/Library/Developer/CoreSimulator/Devices/9D514AC1-E245-4360-B876-745B9527B844/data/Containers/Data/Application/091D48E6-3AE4-4867-B3B2-2034854D27CE/tmp/image_picker_3DA6CDD3-C2F9-4313-98A1-40A7B0AED652-1298-00001B041C9F94E4trim.59BC5143-1EBA-4BB0-955C-EA1942FA56E3.MOV

• ffmpeg progress percentage in php

  9 avril 2018, par Mr.ZZ

  ffmpeg.php

  $sCmd = "ffmpeg -i ".$image." -i ".$music." video.avi 1> progress.txt";
  
  $proc = popen($sCmd." 2>&1", "r");

  progress.php

  $content = @file_get_contents('progress.txt');
  
  if($content){
  
      preg_match("/Duration: (.*?), start:/", $content, $matches);
  
      $rawDuration = $matches[1];
  
      $ar = array_reverse(explode(":", $rawDuration));
  
      $duration = floatval($ar[0]);
  
      if (!empty($ar[1])) $duration += intval($ar[1]) * 60;
  
      if (!empty($ar[2])) $duration += intval($ar[2]) * 60 * 60;
  
      preg_match_all("/time=(.*?) bitrate/", $content, $matches);
  
      $rawTime = array_pop($matches);
  
      if (is_array($rawTime)){$rawTime = array_pop($rawTime);}
  
      $ar = array_reverse(explode(":", $rawTime));
  
      $time = floatval($ar[0]);
  
      if (!empty($ar[1])) $time += intval($ar[1]) * 60;
  
      if (!empty($ar[2])) $time += intval($ar[2]) * 60 * 60;
  
      $progress = round(($time/$duration) * 100);
  
      echo $progress;
  
  }

  progress.php final output was always 100, so it was easy with jquery to hide progress and show download button.

  BUT after changing ffmpeg.php with this command :

  $sCmd = "ffmpeg -loop 1 -r 1 -i ".$image." -i ".$music." -c:a copy -shortest video.avi 1> progress.txt";
  
  $proc = popen($sCmd." 2>&1", "r");

  progress.php output is different numbers above 100(thousands) and jquery can’t figure out ffmpeg process finished or not.

  How to get 100 when ffmpeg finishs working ? I think i need some changes in progress.php because final result in progress.txt is longer than before.

• From jpg to animated gif

  12 mai 2016, par lleoun

  I’m desperate, I need to convert some jpg images into an animated gif.

  I’ve tried ffmpeg, but the result has a terrible quality.

  Also tried imagemagick, and the result looks great but it weights 511 KB !!

  Anyone please can tell me what to use or how to use the before applications to get a final animated gif with a normal quality and a normal weight for a gif ??

  As I said I’m desperate, I need to finish this asap :(

  Thanks a lot
