  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • Where to place the fontfile for the FFmpeg Android drawtext-Filter ?

    13 juin 2018, par jpGerhard

    I’m using the precompiled FFmpeg-Android by Bravobit (via gradle : implementation 'nl.bravobit:android-ffmpeg:1.1.5' ; based on WritingMind’s) with the intention of drawing the current timestamp/location onto a .mp4 file. I am completely new to FFmpeg and have started with Android Studio a few months ago.

    Information :

    • IDE : Android Studio
    • OS : OSX 10.13.5

    My problem :

    I don’t know whether the fontfile needs to be in the Application path on my Phone, in the Android Studio directory or just on a location on my MacBook (so it gets compiled when running the application).

    Basic FFmpeg commands (-version, ...) are working, but I can’t seem to figure out where I have to place my fontfile.

    My current command is as follows :

    -i /path/to/video.mp4 -vf drawtext=fontfile=/users/shared/fonts/arial.ttf :text='Hello World' /path/to/output.mp4

    I’ve tried a lot of variations and always received to following errors :

    Fontconfig error : Cannot load default config file
    [Parsed_drawtext_0 @ 0xecbfd420] impossible to init fontconfig
    [AVFilterGraph @ 0xec9cc140] Error initializing filter ’drawtext’ with args ’fontfile=/users/shared/fonts/arial.ttf:text=Hello World’
    Error reinitializing filters !
    Failed to inject frame into filter network : Unknown error occurred
    Error while processing the decoded data for stream #0:0
    Conversion failed !

    Does anyone have a suggestion on how to get this to work ?

  • FFmpeg vidstab generates jerky wiggling video

    27 mars 2022, par praet0ri4n

    I run Kdenlive 21.12.3 on Ubuntu 20.04.
Recently I stared editing footage from my Nikon D3100 DSLR. Source videos are 1920:1080 24fps in MOV format (camera set to PAL system).

    


    After trying to stabilize a video where I am walking I noticed that the result is kind of stabilized but the image is distorted and contains some strange wiggling effect. Changing the stabilization settings doesn't have any impact on this effect. I haven't seen this before. Previously I stabilized footage from other cameras without problems. This is the first time I use that DSLR.

    


    To me it looks like stabilization is doing some strange interpolation and it is stretching and skewing the image or pixel aspect ratio.
For convenience I tried the vidstab filter with ffmpeg, played around with the interpol option too, but the result ist exactly the same.

    


    Here the source MOV and stabilized mp4 file for comparison

    Thank you !

    


  • Installing gifify on Windows

    23 février 2016, par Robert Wojciechowski

    So gifify is a pretty awesome script that converts videos to gifs via command line : https://github.com/vvo/gifify

    I’m keen to get this working on my Windows 10 machine. I’m pretty new to windows and relatively new to coding, but I was able to get a few things working, but ran into a problem.

    Here is what I did :

    1. Installed node.js + npm
    2. Installed FFmpeg using npm
    3. Installed ImageMagick using npm (i think i did this wrong, might have only installed the wrapper).
    4. Downloaded giflossy. It needed to be built (?)
    5. Installed Visual Studio 2015, tried to build it using nmake and got this error :
    NMAKE : fatal error U1073: don't know how to make 'win32cfg.h'

    The command I used was :

    PS C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin> .\nmake -f "C:\Users\Robert's Workstation\.npm-global\node_modules\giflossy-lossy-1.82.1\src\Makefile.w32"

    Would really appreciate some help with this :D
