  • 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.

  • MediaSPIP en mode privé (Intranet)

    17 septembre 2013, par

    À partir de la version 0.3, un canal de MediaSPIP peut devenir privé, bloqué à toute personne non identifiée grâce au plugin "Intranet/extranet".
    Le plugin Intranet/extranet, lorsqu’il est activé, permet de bloquer l’accès au canal à tout visiteur non identifié, l’empêchant d’accéder au contenu en le redirigeant systématiquement vers le formulaire d’identification.
    Ce système peut être particulièrement utile pour certaines utilisations comme : Atelier de travail avec des enfants dont le contenu ne doit pas (...)

  • Saving individual frames of multiple m3u8 streams

    10 décembre 2023, par Toprak

    I have a list of multiple m3u8 stream URLs. I want to grab individual live frames of these streams and save them locally. I managed to do this with openCv however, the number of streams is around 20, even though I wrote the code using parallel processing and multithreading, some streams wait too long to download the new frames.

    


    Is there a better way or faster module that I can use ? Theoretically it shouldn't be this hard because I can open each stream in browser and the client side player can stream it. I feel like maybe ffmpeg is a solution, but I couldn't find a way to download and save each frame from a stream link by ffmpeg, with a unique name so. it doesn't update all the time.

    


    Edit :
I attempted to this issue with ffmpeg as well, using multithreading , but probably because each time they want to grab a frame, they need to connect, this is slower.

  • ismindex : Use the individual stream duration instead of the global one

    ismindex : Use the individual stream duration instead of the global one

    The stream duration is used for calculating the duration of the
    
last fragment easily without manually parsing anything else than
    
the mfra/tfra atoms. When the global file duration was used
    
previously, the duration of the last fragment could end up wrong
    
if the streams weren’t equally long.
