• How to make terminal refer to more recent ffmpeg installation path (currently refers to Anaconda's installation) ? [on hold]

  29 janvier 2019, par John Doe

  I would like to use ffmpeg to convert a WAV audio file to MP3, but ffmpeg doesn’t have a native MP3 encoder. Their documentation says you can use the external libmp3lame encoding library to achieve this, which "requires the presence of the libmp3lame headers and library during configuration" by "explicitly configur[ing] the build with —enable-libmp3lame."

  I tried installing the latest version of ffmpeg to my desktop and followed the configuration instructions to include libmp3lame. However, when I tried it out in my terminal, I got an error saying that ffmpeg could not find the libmp3lame encoder.

  When I enter "which ffmpeg" into my terminal, the path I am given refers to another, older installation of ffmpeg that was included automatically when I installed Anaconda years ago.

  How can I change the path of the installation my terminal refers to so that when I execute ffmpeg commands, it will use the version I more recently configured to include libmp3lame on my desktop and not the older installation included in Anaconda’s directories ?

• 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

• 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.
