• PHP-FFMpeg not converting (error with ffmpeg)

  13 août 2016, par Magurean Dan Sergiu

  I have installed ffmpeg server side with all the dependencies, updated it. And then installed PHP-FFMpeg with Composer. Tested that ffmpeg is instaled with a ssh conexion.

  root@host [/opt/ffmpeg]# ffmpeg

  Use -h to get full help or, even better, run 'man ffmpeg'

  But when I try to convert a video file with a php script it throws me a very long error.
  PHP Code :

  <?PHP
  
  include($_SERVER['DOCUMENT_ROOT']."/vendors/install/vendor/autoload.php");
  
  $ffmpeg = FFMpeg\FFMpeg::create();
  
  $video = $ffmpeg->open($_SERVER['DOCUMENT_ROOT'].'/resources/uploads/96048/ffd3c5e349fa5745159deef163b5c253.wmv');
  
  $video
  
         ->filters()
  
         ->synchronize();
  
  $format = new FFMpeg\Format\Video\X264();
  
  $format->on('progress', function ($video, $format, $percentage) {
  
      echo "$percentage % transcoded";});
  
  $video
  
        ->save($format,$_SERVER['DOCUMENT_ROOT'].'/resources/uploads/96048/ffd3c5e349fa5745159deef163b5c253.mp4');
  
  ?>

  Error displayed :

  <b>Fatal error</b>:  Uncaught exception 'Alchemy\BinaryDriver\Exception\ExecutionFailureException' with message 'ffmpeg failed to execute command '/usr/local/bin/ffmpeg' '-y' '-i' '/home/user/working/resources/uploads/23097/2efeb41a1a7085a1dbd469c4895ac23e.wmv' '-async' '1' '-metadata:s:v:0' 'start_time=0' '-threads' '12' '-vcodec' 'libx264' '-acodec' 'libfaac' '-b:v' '1000k' '-refs' '6' '-coder' '1' '-sc_threshold' '40' '-flags' '+loop' '-me_range' '16' '-subq' '7' '-i_qfactor' '0.71' '-qcomp' '0.6' '-qdiff' '4' '-trellis' '1' '-b:a' '128k' '-pass' '1' '-passlogfile' '/tmp/ffmpeg-passes57ad320a1b685j794u/pass-57ad320a1b716' '/home/user/working/resources/uploads/23097/2efeb41a1a7085a1dbd469c4895ac23e.mp4'' in /home/user/working/vendors/install/vendor/alchemy/binary-driver/src/Alchemy/BinaryDriver/ProcessRunner.php:100↵Stack trace:↵#0 /home/user/working/vendors/install/vendor/alchemy/binary-driver/src/Alchemy/BinaryDriver/ProcessRunner.php(72): Alchemy\BinaryDriver\ProcessRunner-&amp;gt;doExecutionFailure(''/usr/bin/ffmpe...')↵#1 / in <b>/home/user/working/vendors/install/vendor/php-ffmpeg/php-ffmpeg/src/FFMpeg/Media/Video.php</b> on line <b>168</b><br />↵"

  Then I have took the basic code displayed upwards and ran it directly through ssh.

  And this is the response I get :

  Unknown encoder 'libx264'

  My question is what to do next ? I have wasted 3 days to make this work and this is the furthest I have come. How can I test if libx264 is installed corectly ? And if it is not installed corectly how cand I reinstal or make it work ?

• "File doesn't exist" - streamio FFMPEG on screenshot after create method

  3 mai 2013, par dodgerogers747

  I have videos being directly uploaded to S3 using Amazon's CORS configuration. Videos are uploaded via a dedicated S3 form, once they have been uploaded successfully the URL of the video is appended to the @video.file hidden_field via javascript and then the video saves.

  I can't get this after_save method to work which takes a screenshot of the video and saves it to S3 via carrierwave after the video has been saved as a rails object. ( It was previously working using a carrierwave video upload instance )

  It errors out withErrno::ENOENT - No such file or directory - the file 'http://bucket-name.s3.amazonaws.com/uploads/video/file/secure-random-hex/video_name.m4v' does not exist: I have tried running this method as a class method to call it from the console but it always comes back with the same error, even though the video exists.

  My bucket is set to public, read and write. How come it doesn't think the file exists ?

  If anyone needs more code just shout, thanks in advance.
