• FFMpeg Concatenation Filters : Stream specifier ':0' in filtergraph matches no streams

  7 février 2017, par Anthony Eden

  I am developing an application that relies heavily on FFMpeg to perform various transformations on audio files. I am currently testing my FFMpeg configuration on the command line.

  I am trying to concatenate multiple audio files which are in different formats (Primarily MP3, MP2 & WAV). I have been using the official TRAC documentation (https://trac.ffmpeg.org/wiki/How%20to%20concatenate%20(join%2C%20merge)%20media%20files#differentcodec) to help me with this and have created the following command :

  ffmpeg -i OHIn.wav -i OHOut.wav -filter_complex '[0:0] [1:0] concat=n=2:a=1 [a]' -map '[a]' output.wav

  However, when I run this on Mac OS X using version 2.0.1 of FFMpeg, I get the following error message :

  Stream specifier ':0' in filtergraph description [0:0] [1:0] concat=n=2:a=1 [a] matches no streams.

  Here is my full output from the terminal :

  ~/ffmpeg -i OHIn.wav -i OHOut.wav -filter_complex '[0:0] [1:0] concat=n=2:a=1 [a]' -map '[a]' output.wav

  Stream specifier ':0' in filtergraph description [0:0] [1:0] concat=n=2:a=1 [a] matches no streams.

  I do not understand why this does not work. FFMpeg shows that the streams 0:0 and 1:0 exist in the source files. The only other similar problems online have surrounded the use of the single quote in Windows, however testing of this confirm it does not apply to my Mac command line.

  Any help would be much appreciated.

• 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

  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 ?
