  • 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.

  • Encoding and processing into web-friendly formats

    13 avril 2011, par

    MediaSPIP automatically converts uploaded files to internet-compatible formats.

    Audio files are encoded in MP3 and Ogg (supported by HTML5) and MP3 (supported by Flash).
    Where possible, text is analyzed in order to retrieve the data needed for search engine detection, and then exported as a series of image files.
    All uploaded files are stored online in their original format, so you can (...)

  • No output file when converting audio using FFmpeg in Android

    18 mars 2017, par Sha

    I’m trying to convert m4a audio file to wav using FFmpeg. The code executes fine and gives no error, but I don’t see any output file in my directory.

    This is what I am executing :

    String[] cmd = {"-y", "-i", "/storage/emulated/0/jd.m4a", "-f","wav" ,"/storage/emulated/0/DCIM/Camera/output.wav"};

    And this is what gets printed :

  • Generate fmp4 chunks for HLS with ffmpeg

    9 mars 2017, par genxstylez

    I am trying to generate fragmented MP4 as the chunks for HLS as introduced by apple last year.

    Does ffmpeg supports this ?

    Thanks !

  • Retire FLAC__float and FLAC__double types

    8 février 2016, par Thomas Zander
    Retire FLAC__float and FLAC__double types

    Usage of internal aliases for float and double do not provide
    
substantial value. For integer-only libs, the macro
    
FLAC__INTEGER_ONLY_LIBRARY is used in the appropriate places
    
already.
    

    Also, adapt copyright messages to include 2016.
