  • L’agrémenter visuellement

    10 avril 2011

    MediaSPIP est basé sur un système de thèmes et de squelettes. Les squelettes définissent le placement des informations dans la page, définissant un usage spécifique de la plateforme, et les thèmes l’habillage graphique général.
    Chacun peut proposer un nouveau thème graphique ou un squelette et le mettre à disposition de la communauté.

  • Taille des images et des logos définissables

  • Error 'paquete de entrada dañado en la secuencia 1' en FFMPEG [closed]

    25 septembre 2022, par Samuel Moya Donoso

    Tengo un videoclip que pesa 1.84 GB, no me dice el tiempo de duración pero calculo que dura 15 minutos y estoy tratando de ejecutar el siguiente comando :

    


    ffmpeg.exe -r 50.000 -i result.h264 -i result.aac -bsf:a aac_adtstoasc -c:v copy -c:a copy result.mov


    


    Pero entonces obtengo el siguiente error :

    


    Error applying bitstream filters to an output packet for stream #0:1.
result.aac: Invalid data found when processing input

Error applying bitstream filters to an output packet for stream #0:1.

  • How can I build a custom version of opencv while enabling CUDA and opengl ? [closed]

    10 février, par Josh

    I have a hard requirement of python3.7 for certain libraries (aeneas & afaligner). I've been using the regular opencv-python and ffmpeg libraries in my program and they've been working find.

    


    Recently I wanted to adjust my program to use h264 instead of mpeg4 and ran down a licensing rabbit hole of how opencv-python uses a build of ffmpeg with opengl codecs off to avoid licensing issues. x264 is apparently opengl, and is disabled in the opencv-python library.

    


    In order to solve this issue, I built a custom build of opencv using another custom build of ffmpeg both with opengl enabled. This allowed me to use the x264 encoder with the VideoWriter in my python program.

    


    Here's the dockerfile of how I've been running it :

    My trouble now, is I've been considering running parts of my program on my GPU, it's creating graphics for a video after all. I have no idea how to edit my Dockerfile to make the opencv build run with CUDA enabled, every combination I try leads to issues.

    


    How can I tell which version of CUDA, opencv and ffmpeg are compatible with python 3.7 ? I've tried so so many combinations and they all lead to different issues, I've asked various AI agents and they all flounder. Where can I find a reliable source of information about this ?
