• how to update ffmpeg password in Config.php

  15 décembre 2014, par Ray Martin Balilo

  I have successfully installed PHP FFMPEG on my laptop which is windows 8 (I was using xampp) following this guide

  http://myownhomeserver.com/2012/12/how-to-install-ffmpeg-php-php-5-4-on-windows-8-xampp-1-8-1/

  after installing it, the test file is working just right. Then after that i try the video conversion guide following this

  http://myownhomeserver.com/2012/12/how-to-run-execute-ffmpeg-with-php-on-windows-pc/

  my problem is that when i try to click the convert it button. It says that "The page at localhost:8080 says : Request failed !"

  according to the comment in the guide the solution is i need to update the password of ffmpeg in config.php

  this is the code of config.php :

  <?php
  
  /**
  
  * Configuration File 
  
  *
  
  * @ver     0.1
  
  */
  
  define('DS', DIRECTORY_SEPARATOR);
  
  
  
  define('BASE_PATH', realpath(dirname(__FILE__)) . DS);
  
  
  
  $_protocol = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != "off") ? "https" : "http";
  
  
  
  define('BASE_URL', $_protocol ."://". $_SERVER['HTTP_HOST'] . dirname($_SERVER['SCRIPT_NAME'])      .'/');
  
  
  
  // Videos to convert path
  
  define('SOURCE_PATH', BASE_PATH . 'source'. DS);
  
  
  
  // Converted videos output path
  
  define('OUTPUT_PATH', BASE_PATH .'output'. DS);
  
  
  
  // Logs Path
  
  define('LOG_PATH', BASE_PATH .'logs'. DS);
  
  
  
  // POST URL for Javascript Queries
  
  define('POST_URL', BASE_URL .'process.php');
  
  
  
  // Execution Script URL (Where the ffmpeg command will be posted to)
  
  define('EXEC_URL', BASE_URL .'ffmpegExec.php');
  
  
  
  // FFMPEG Path (ffmpeg.exe)
  
  define('FFMPEG_PATH', BASE_PATH .'ffmpeg\bin\ffmpeg.exe');
  
  
  
  // FFMPEG Password (Change the value 't^$bG1c4=9u63yyKLmW7Q71tu17p5q' with something new!)
  
  define('FFMPEG_PW', sha1('sdfdfe'));
  
  
  
  if( !file_exists(SOURCE_PATH) )
  
      mkdir(SOURCE_PATH, 0755, true);
  
  
  
  if( !file_exists(OUTPUT_PATH) )
  
      mkdir(OUTPUT_PATH, 0755, true);
  
  
  
  if( !file_exists(LOG_PATH) )
  
     mkdir(LOG_PATH, 0755, true);

  My problem is I dont know how to locate the password of ffmpeg in my windows 8 laptop. Can someone tell me how can I locate the password of ffmpeg ?
  I know I need to make some minor changes in config.php, mainly setting the FFMPEG_PATH constant to the correct location for my Windows computer. But I dont know how... please someone help me please

  Thanks for the help in advance

• How to setup ffmpeg for CentOS release 6.5 server

  23 juillet 2015, par hitesh

  I need to create a screen shot from video,

  I have followed this tutorial to do the intial setup in window 8, php 5.3

  1) I downloaded the ffmpeg from here -[
  http://ffmpeg.zeranoe.com/builds/ ] for 64 bit operating system.

  2) I followed the https://www.youtube.com/watch?v=gU49GiWGGAI , video and did all configuration successfully and phpinfo() shows that ffmpeg has been installed.

  3) Then I tried this to find out whether it is working or not,

  It worked successfully

  4) Next I followed this video tutorial here and thumbnails were created successfully.

  below is my code

  /**
  
   * FFMPEG-PHP Test Script
  
   *
  
   * Special thanks to http://www.sajithmr.me/ffmpeg-sample-code for this code example!
  
   * See the tutorial at http://myownhomeserver.com on how to install ffmpeg-php.

  // Check if the ffmpeg-php extension is loaded first
  
  extension_loaded('ffmpeg') or die('Error in loading ffmpeg');
  
  
  
  // Determine the full path for our video
  
  $vid = realpath('./videos/myvideo.mp4');
  
  $videosize = filesize($vid);
  
  $remoteVideo = 'http://video-js.zencoder.com/oceans-clip.mp4';

  $ffmpeg = dirname(__FILE__) . "\\ffmpeg\\bin\\ffmpeg";
  
  $imageFile = "1.png";
  
  $image2 = "2.png";
  
  $size = "120x90";
  
  $getfromsecond = 7;
  
  $cmd = "$ffmpeg -i $vid -an -ss $getfromsecond -s $size $imageFile";
  
  $cmd2 = "$ffmpeg -i $remoteVideo -an -ss $getfromsecond -s $size $image2";
  
  if(!shell_exec($cmd)){
  
      echo "Thumbnail created";
  
  }else{
  
      echo "Error Creating thumbnail";
  
  }
  
  
  
  if(!shell_exec($cmd2)){
  
      echo "Thumbnail for remote url was created";
  
  }else{
  
      echo "Error Creating thumbnail for remote url ";
  
  }

    OUTPUT
  
      Thumbnail created
  
      Thumbnail for remote url was created

  Now above code works as expected in my local, in window machine , I need to do it in my server environment(Linux server) with php 5.5. How do I do the configuration for ffmpeg in CentOS release 6.5 server with php 5.5.

  I have followed this tutorial to install it in server

  But in server when I open my php file I am getting this error Error in loading ffmpeg

  Also I have checked phpinfo(), It shows ffmpeg installed in my local but not in server.

• Matplotlib animation won't save

  17 décembre 2014, par abe678

  I am trying to learn how to create matplotlib animations by using Jake Vanderplas’s basic example, but I’m having trouble getting the figure to save. I installed ffmpeg on my Mac via homebrew.

  The only changes that I have made are to add :

  import matplotlib
  
  matplotlib.use('TKAgg')

  When I run this script I receive the following error :

  anim.save('basic_animation.mp4', fps=30, extra_args=['-vcodec', 'libx264'])
  
  TypeError: save() got an unexpected keyword argument 'extra_args'

  Based on the many other similar questions, I’ve tried setting the ffmpeg path with

  plt.rcParams['animation.ffmpeg_path']

  but that also gives me an error :

  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/matplotlib/__init__.py", line 660, in __setitem__
  
    See rcParams.keys() for a list of valid parameters.' % (key,))
  
  KeyError: 'animation.ffmpeg_path is not a valid rc parameter.See rcParams.keys() for a list of valid parameters.'

  After removing the rcParams setting, I also tried adjusting the save command to avoid the aforementioned TypeError :

  try:
  
      anim.save('basic_animation.mp4', fps=30, extra_args=['-vcodec', 'libx264'])
  
  except TypeError:
  
      anim.save('basic_animation.mp4', fps=30)

  This runs with no error, but the mp4 file is not created. I have read over every thread and tried every solution I can find, but nothing changes. The plt.show() call works just fine. Can anyone please point me in the right direction ? Thanks !

  Update : I’m using matplotlib version 1.1.1
