  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • 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 (...)

  • Can x264 be used from Java code via JNI to decrease the resolution of RTMP streams ? [on hold]

    5 septembre 2016, par Orr151

    I would like to implement a custom RTMP transcoder to HLS format in Java. As the repackaging itself seems to be relatively clear and doable in Java, then I found the modification of the video resolution a bit challenging in Java. My plan is to avoid using existing solutions like FFmpeg or at least minimize the amount of 3rd party frameworks/tools integrated with my component.

    After some research it seems that reusage of JCodec and Xuggler can be challenging as both project are idle for a while. Also I’m not sure if their performance is acceptable. That’s why I would like to integrate directly with x264 library via JNI from Java code.

    Is integration with x264/libx264 from Java code to decrease resolution/bitrate doable and is it a good idea ? Could you please suggest any other solutions ?

    Thanks !

  • Evolution #3820 : modération des inscriptions de rédacteur

    5 septembre 2016, par b b

    Quelques remarques que je postais sur IRC à ce sujet :

    Ça fait chier, on va devoir ajouter une chaîne de langue, du coup ça ne sera pas reportable en 3.0 et 2.1.

    Techniquement, on doit pouvoir tout gérer depuis action/inscrire_auteur, le plan :

    • toujours envoyer le mail de confirmation au nouvel auteur, mais sans le lien de confirmation dedans
    • envoyer le mail de confirmation avec le lien de validation aux admins

    Par contre, si on a pas de page de gestion des inscriptions en attente, ça va être la merde à gérer. Si un admin ne reçoit pas le mail de confirmation ou qu’il passe dans ses spams, comment il fait pour valider le compte en attente ?

    Je ne suis pas certain que ça soit une modif mineure.

  • FFmpeg pseudocolor filter - Option 'p' not found Error initializing filter 'pseudocolor' with args 'p=inferno'

    5 février 2023, par Greynol4

    I'm trying to process output from a uvc camera using ffmpeg. The original command that I was given that works on another linux distribution is :

    


    ffmpeg -input_format yuyv422 -video_size 256x384 -i /dev/video0 -vf 'crop=h=(ih/2):y=(ih/2)' -pix_fmt yuyv422 -f rawvideo - | ffplay -pixel_format gray16le -video_size 256x192 -f rawvideo -i - -vf 'normalize=smoothing=10, format=pix_fmts=rgb48, pseudocolor=p=inferno'

    


    (yes it works on his machine, I've seen the screen capture)

    


    I can get everything but the pseudocolor filter to work and this command works fine if i just delete , pseudocolor=p=inferno

    


    This is for processing the stream from a thermal camera that outputs raw data as video which necessitates the cropping and processing and is also why the resolution is so low.

    


    No matter what I do, it throws - Option 'p' not found Error initializing filter 'pseudocolor' with args 'p=inferno' \[rawvideo @ 0x625007a0\] Packet corrupt (stream = 0, dts = 3).=0/0 
I have modified it for my needs but I still cant get the pseudocolor filter to use the presets.

    


    The full configuration and output are below. This is a raspberry pi 3B+ running bullseye that I've reinstalled multiple times without resolution of this problem.

    The examples for the presets in the documentation are lacking but that makes me think that it shouldn't be giving this much trouble and I'm overlooking something.

    


    I plan on integrating this but can't until I can proceed with this proof of concept.

    


    Thanks for any help !
