• FFMpeg : ffmpeg failed to execute command error

  4 mars 2020, par Richard McFriend Oluwamuyiwa

  I am trying to transcode a video file of 1.2mb file uploaded to my website server via php/html upload, but I keep getting the error :

  PHP Fatal error :

  Funny thing is that the same server is extracting frames and getting duration of the same file using ffprobe and ffmpeg.

  Here is the code I am using to transcode :

  $ffmpeg = $ffmpeg = FFMpeg\FFMpeg::create(['timeout'=>3600, 'ffmpeg.thread'=>12, 'ffmpeg.binaries'  => '/usr/local/bin/ffmpeg',
  
      'ffprobe.binaries' => '/usr/local/bin/ffprobe']);
  
  
  
              $ffprobe_prep = FFMpeg\FFProbe::create(['ffmpeg.binaries'  => '/usr/local/bin/ffmpeg',
  
      'ffprobe.binaries' => '/usr/local/bin/ffprobe']);
  
              $ffprobe = $ffprobe_prep->format($video_file);
  
  
  
              $video = $ffmpeg->open($video_file);
  
  
  
              // Get video duration to ensure our videos are never longer than our video limit.
  
              $duration = $ffprobe->get('duration');
  
  
  
              // Use mp4 format and set the audio bitrate to 56Kbit and Mono channel.
  
              // TODO: Try stereo later...
  
              $format = new FFMpeg\Format\Video\X264('libmp3lame', 'libx264');
  
              $format
  
                  -> setKiloBitrate(128)
  
                  -> setAudioChannels(1)
  
                  -> setAudioKiloBitrate(8);
  
  
  
              $first = $ffprobe_prep
  
                          ->streams($video_file)
  
                          ->videos()
  
                          ->first();
  
  
  
              $width = $first->get('width');
  
  
  
              if($width > VIDEO_WIDTH){
  
                  // Resize to 558 x 314 and resize to fit width.
  
                  $video
  
                      ->filters()
  
                      ->resize(new FFMpeg\Coordinate\Dimension(VIDEO_WIDTH, ceil(VIDEO_WIDTH / 16 * 9)));
  
              }
  
  
  
              // Trim to videos longer than three minutes to 3 minutes.
  
              if($duration > MAX_VIDEO_PLAYTIME){
  
  
  
                  $video
  
                      ->filters()
  
                      ->clip(FFMpeg\Coordinate\TimeCode::fromSeconds(0), FFMpeg\Coordinate\TimeCode::fromSeconds(MAX_VIDEO_PLAYTIME));
  
              }
  
  
  
              // Change the framerate to 16fps and GOP as 9.
  
              $video
  
                  ->filters()
  
                  ->framerate(new FFMpeg\Coordinate\FrameRate(16), 9);
  
  
  
              // Synchronize audio and video
  
              $video->filters()->synchronize();
  
  
  
              $video->save($format, $video_file_new_2);

  I have contacted my host to no vital assistance. The only useful information they can provide me is that ffmpeg was compiled on the server with libmp3lame support.

  This code works perfect on localhost

  Any help as to why I may be getting the error and how to correct it is appreciated.

• FFMPEG&PHP : Videos modified by FFMPEG are not played in Firefox

  22 juillet 2016, par Drupalist

  I use this code to cut a section of a video

  exec("ffmpeg -i ".$url." -ss ".$start." -to ".$end." -c copy ".$result);

  This code works very well, and the result is played in Google Chrome and IE, but the firefix reports

  no video with supported mime type found.

  The $url which is the source video, is played in all browsers.

  The video format is .mp4 and the player is html5 player of the browser. How can I solve this problem ?
