    31 janvier 2010, par

    Le chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.
    Upload et récupération d’informations de la vidéo source
    Dans un premier temps, il est nécessaire de créer un article SPIP et de lui joindre le document vidéo "source".
    Au moment où ce document est joint à l’article, deux actions supplémentaires au comportement normal sont exécutées : La récupération des informations techniques des flux audio et video du fichier ; La génération d’une vignette : extraction d’une (...)

  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • avcodec/mpeg12dec : Sanitize start codes earlier

    20 septembre 2019, par Andreas Rheinhardt
    avcodec/mpeg12dec : Sanitize start codes earlier

    The MPEG-1/2 decoder uses avpriv_find_start_code to search for start
    
codes and worked with the resulting start code before checking that it
    
is really a start code of a slice. In particular, if the picture is so
    
big that a slice_vertical_position_extension is present, it added the
    
slice_vertical_position_extension as if it had a slice. Then a left
    
shift is performed, without making sure that the value to be shifted is
    
nonnegative.
    
Afterwards the end result is checked, but even if a start code of a
    
non-slice has been found, it might pass these checks : If
    
slice_vertical_position_extension is present a start code <
    
SLICE_MIN_START_CODE can lead to a macroblock-row index that appears
    
valid. Furthermore, the left shift might make an invalid start code
    
appear valid by discarding the highest bit.
    
This has been fixed by checking directly after avpriv_find_start_code
    
has returned.
    

    Fixes ticket #8162 (which is about the undefined left shifts).

  • PHP - How to run commandline apps on server ? [duplicate]

    20 décembre 2016, par zeddex

    This question is an exact duplicate of :

    I have been coding with PHP for a while now and have used things like FFMPEG on Windows XAMPP without any problems. Now however i have been trying to run the FFMPEG commandline on my Godaddy hosting account with PHP as i wanted to make a web based project but cannot get it working.

    On windows with ffmpeg.exe and sound.wav in the same directory this works :

    WavToMP3.php

    &lt;?php
    

    
exec("ffmpeg.exe -i sound.wav -ar 44100 -ac 2 -c:a libmp3lame -b:a 320k sound.mp3");
    

    
?>

    Yet it does not run on Godaddy, i know they use linux though so i tried this :

    http://download1.rpmfusion.org/free/fedora/releases/25/Everything/x86_64/os/repoview/ffmpeg-compat.html

    I downloaded :

    http://download1.rpmfusion.org/free/fedora/releases/25/Everything/x86_64/os/Packages/f/ffmpeg-compat-0.6.7-9.fc25.i686.rpm

    Then in the script i changed "ffmpeg.exe" to just "ffmpeg" but it still did not work.

    I have no idea about running linux commandlines as i have only ever used Windows in the past.

    What are the instructions needed that can get the above PHP code or a modified version to generate a .mp3 file using my Godaddy hosting account ?
