  • Le plugin : Podcasts.

    14 juillet 2010, par

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
    Types de fichiers supportés dans les flux
    Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

  • 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.

  • omxplayer freezes with videos generated with FFMPEG

    31 décembre 2020, par Chocksmith

    Omxplayer won't play any videos generated with FFmpeg on a Raspberry Pi

    


    I found this thread showing that it is necessary to include '-profile baseline -level 3.0' parameters : https://github.com/popcornmix/omxplayer/issues/577

    


    The full command is :

    


    ffmpeg -framerate 1/10 -pattern_type glob -i '*.jpg' -c:v libx264 -pix_fmt yuv420p -profile baseline -level 3.0 images.mp4


    


    I did that and now I am experiencing intermittent behavior.

    


    Sometimes it works and sometimes it does not work. I cannot explain why/when it plays or not.

    


    I also found a thread showing that it is necessary to upgrade the firmware and player. I did that and still having the same issue.

    


    Here is an example. First time it plays ok. Second time it freezes.

    


    First time : creating mp4

  • Core : fixed Regular Expression Denial of Service vulnerability (#2371)

    Core : fixed Regular Expression Denial of Service vulnerability (#2371)
    

    ReDoS, or Regular Expression Denial of Service, is a vulnerability affecting
    poorly constructed and potentially inefficient regular expressions which can
    make them perform extremely badly given a creatively constructed input string.

  • python suggests ffmpeg installation when it is installed

    17 janvier 2021, par FNTE

    I have a problem related to the bar_chart_race python package. I have installed ffmpeg but when I execute my code, I get :

    


    You do not have ffmpeg installed on your machine. 
Download from here: https://www.ffmpeg.org/download.html.


    


    I know that I have used this package before and it was all good. I have installed ffmpeg version :
