  • (Dés)Activation de fonctionnalités (plugins)

    18 février 2011, par

    Pour gérer l’ajout et la suppression de fonctionnalités supplémentaires (ou plugins), MediaSPIP utilise à partir de la version 0.2 SVP.
    SVP permet l’activation facile de plugins depuis l’espace de configuration de MediaSPIP.
    Pour y accéder, il suffit de se rendre dans l’espace de configuration puis de se rendre sur la page "Gestion des plugins".
    MediaSPIP est fourni par défaut avec l’ensemble des plugins dits "compatibles", ils ont été testés et intégrés afin de fonctionner parfaitement avec chaque (...)

  • Activation de l’inscription des visiteurs

    12 avril 2011, par

    Il est également possible d’activer l’inscription des visiteurs ce qui permettra à tout un chacun d’ouvrir soit même un compte sur le canal en question dans le cadre de projets ouverts par exemple.
    Pour ce faire, il suffit d’aller dans l’espace de configuration du site en choisissant le sous menus "Gestion des utilisateurs". Le premier formulaire visible correspond à cette fonctionnalité.

  • MediaSPIP : Modification des droits de création d’objets et de publication définitive

    11 novembre 2010, par

    Par défaut, MediaSPIP permet de créer 5 types d’objets.
    Toujours par défaut les droits de création et de publication définitive de ces objets sont réservés aux administrateurs, mais ils sont bien entendu configurables par les webmestres.
    Ces droits sont ainsi bloqués pour plusieurs raisons : parce que le fait d’autoriser à publier doit être la volonté du webmestre pas de l’ensemble de la plateforme et donc ne pas être un choix par défaut ; parce qu’avoir un compte peut servir à autre choses également, (...)

  • 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 !

    


  • How does a video editor app do fast realtime rendering ? [closed]

    I plan to make a video editor using the Flutter framework, but I'm still having trouble doing realtime rendering. How do I do fast realtime rendering ?
