• Error : No such filter : '"movie', what's the isssue ?

  16 mars 2019, par uno

  I am using the code to add watermarks to videos on upload for carrierwave-video :

  process encode_video: [:mp4, resolution: "640x480", watermark: {
  
      path: "app/assets/images/logo-nike.jpg",
  
      position: :bottom_right,
  
      pixels_from_edge: 10
  
    }]

  When i use this code, i get error :

  (in short)

  Stream mapping:
  
    Stream #0:0 -> #0:0 (h264 (native) -> h264 (libx264))
  
    Stream #0:1 -> #0:1 (aac (native) -> aac (native))
  
  Press [q] to stop, [?] for help
  
  [AVFilterGraph @ 0x55c8909bf180] No such filter: '"movie'
  
  Error reinitializing filters!
  
  Failed to inject frame into filter network: Invalid argument
  
  Error while processing the decoded data for stream #0:0
  
  Conversion failed!
  
  ):

  my ffmpeg version is 4.1.1

  Is there something missing from ffmpeg i need to install ? I have looked around and found no issues with others using this code (most posts are years old though)

  I found this : No such filter : ’drawtext’

  but isn’t the same thing ?

• Developing a multi-tool video & audio program

  14 février 2019, par Risviltsov

  I’m in the middle of the Microsoft TEALS Java program, and we’ve just done a picture editor. I got an idea to develop a multi-tool program that edits video and audio programs professionally for those who can’t afford $2,000 in editing programs but demand all the tools. I’ve ran into a brick wall with the planning :

  What tools should I put in it ? I want this program to have most, if not all possible ways to change media files (as if I was to combine programs like Audacity, a lot of Adobe programs, etc.)

  I’m learning up FFMPEG and AWT, but I really want to tackle this project’s planning this year, to tackle on the programming in the next two years independently. Yay straightforward freeware* & too much time !

  (I don’t think this post belongs here, but I’m in search of help for I have no budget nor any help [it’s going into culinary])

  Thanks for your time.

• How do you include ffmpeg in a php enviroment

  6 février 2019, par Joseph Williamson

  So looking through documentation and answers on stack overflow all leave out one detail thats throwing me off and thats how to actually include the library

  Following along the code listed here ffmpeg-php to create thumbnail of video

  class VideoTile
  
  {
  
      public static function createMovieThumb($srcFile, $destFile = "test.jpg")
  
      {
  
          // Change the path according to your server.
  
          $ffmpeg_path = 'D:\\ffmpeg\\bin\\';
  
  
  
          $output = array();
  
  
  
          $cmd = sprintf('%sffmpeg -i %s -an -ss 00:00:05 -r 1 -vframes 1 -y %s', 
  
              $ffmpeg_path, $srcFile, $destFile);
  
  
  
          if (strtoupper(substr(PHP_OS, 0, 3) == 'WIN'))
  
              $cmd = str_replace('/', DIRECTORY_SEPARATOR, $cmd);
  
          else
  
              $cmd = str_replace('\\', DIRECTORY_SEPARATOR, $cmd);
  
  
  
          exec($cmd, $output, $retval);
  
  
  
          if ($retval)
  
              return false;
  
  
  
          return $destFile;
  
      }
  
  }

  The ffmpeg path is D:\\ffmpeg\\bin\\ I have downloaded the latest release for ffmpeg(4.1) and the uncompressed file does not contain any directory for bin

  I am very confused as to actually use this even with detailed code saying how to if I do not even know how to dictate the proper path

  I also realize that the link is almost 5 years old but as there are no post outlining how to do this in so long I figure its about time for some clear,concise, detailed solutions
