  • 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]

    14 février 2023, par aya Cangtip

    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 ?
