• ffmpeg/ffprobe to produce a numeric array output

  29 décembre 2015, par edwardsmarkf

  i have been using this npm module : to create a waveform numeric output such as this below :

  [0,0.0062,0.0688,0.2524,0.2691,0.2645,0.1594,0.1397,0.1672

  however, this module may not be supported very well and has not been maintained for a couple of years now. the module describes itself as a "tiny wrapper around ffprobe".

  my question - what would the ffmpeg/ffprobe command line look like to produce a numeric array output ?

  thank you very much.

• FFMPEG installation & configuration with xampp on fedora

  10 octobre 2013, par UMI

  I have running Fedora 8, where I have installed XAMPP-Linux. First I installed latest version with Xampp-Linux-1.8.3 including PHP 5.5 from "http://www.apachefriends.org/en/xampp-linux.html".

  After setting up everything, tried to install "FFMPEG" from "http://www.nixgurus.com/fedora/installing-ffmpeg-using-yum-on-centos-redhat-fedora/". This is the only guide which gets completed with successful installation and configuration, otherwise all other tried tutorials got leave me middle of nowhere.

  Note : While installing FFMPEG following above provided URL, "phpize" did not work to me so I had to install php-devel by running "yum install php-devel" command. I always got different "Zend Module" and "Zend Extension API" versions.

  When I installed ffmpeg and put extension in "php.ini" with correct path, it never appeared in phpinfo().

  Then after searching, I got a hint that installed "FFMPEG" will not be compatible to the installed PHP version. So I removed complete pack of XAMMP-LINUX and installed old one with Xampp-Linux-1.8.2 including PHP 5.4. But it result were same.

  Then, I decided to use more older version and it was Xampp-Linux-1.8.1 including PHP 5.4. Now currently I have this version but having version results are totally changed that after installation of FFMPEG when I put ffmpeg.so with its correct path in PHP.INI (definitely restart the server on every change) server behaves strange way that PHP files get downloaded by browsers and when I comment same line and restart web server everything works well.

  Just to let you know that, even I have given path "extension=/usr/lib/php/modules/ffmpeg.so" which did not work and even moved files to default extension path "/opt/lampp/lib/php/extensions/no-debug-non-zts-20100525" as well but in vain.

  Looking forward to your help please.

• FFMPEG on Fedora but PHP Compilation confliction

  11 octobre 2013, par UMI

  I have running Xampp with PHP5.5 on Fedora from Apache Friend, with default settings what the installer package do on Linux.

  When I install FFMPEG successfully and try to load from php.ini it always says :

  *

  11-Oct-2013 14:05:51 Europe/Berlin] PHP Warning:  PHP Startup: ffmpeg: Unable to initialize module
  
  Module compiled with module API=20060613
  
  PHP    compiled with module API=20121212
  
  These options need to match
  
  in Unknown on line 0

  *

  The only thing which is confusing me is that when I did phpize even that I already installed xampp server which means I have PHP running. FFMPEG phpize did not work and I had to install php-devel. Does that mean that FFMPEG is configured with PHP, other than the installed with XAMPP ? I am not sure what is happening. Whatever I do I always receive this error message in php_error_log file.

  It is amazing :) that I just run below command to see what version of PHP is, I have and below are the results which are shocking one because I am in a feeling that I have PHP 5.5 installed and running from XAMMP.

  [root@localhost ~]# php -v
  
  PHP 5.2.6 (cli) (built: May  8 2008 08:53:44)
  
  Copyright (c) 1997-2008 The PHP Group
  
  Zend Engine v2.2.0, Copyright (c) 1998-2008 Zend Technologies

  How can I get this covered that if I simple install XAMPP server on linux and want to install and configure FFMPEG along with ?
