    Jolie sélection multiple
    Le plugin Chosen permet d’améliorer l’ergonomie des champs de sélection multiple. Voir les deux images suivantes pour comparer.
    Il suffit pour cela d’activer le plugin Chosen (Configuration générale du site > Gestion des plugins), puis de configurer le plugin (Les squelettes > Chosen) en activant l’utilisation de Chosen dans le site public et en spécifiant les éléments de formulaires à améliorer, par exemple select[multiple] pour les listes à sélection multiple (...)

  • 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" (...)

  • How to stop ffmpeg automatically rotating (Iphone 13) videos

    22 juillet 2022, par VdGR

    I have a bunch of videos I want to merge into one video.
Therefore I used this ffmpeg command.

    


    ffmpeg -y -loglevel warning -f concat -safe 0  -i "filelist.txt" -c copy "merged.mov"


    


    When I open merged.mov all my videos are rotated -90 degerees but when I open my videos for example in vlc it has the right rotation.
What am I doing wrong ?

    


    I tried already adding the "-noautorotate" option but that does not seem to solve the problem.

    


  • Conversion from Iphone Core Surface RGB Frame into ffmepg AVFarme

    10 mars 2015, par Raghu

    I am trying to convert Core Surface RGB frame buffer(Iphone) to ffmpeg Avfarme to encode into a movie file. But I am not getting the correct video output (video showing colors dazzling not the correct picture)

    I guess there is something wrong with converting from core surface frame buffer into AVFrame.

    Here is my code :

    Surface *surface = [[Surface alloc]initWithCoreSurfaceBuffer:coreSurfaceBuffer];
    
[surface lock];
    
unsigned int height = surface.height;
    
unsigned int width = surface.width;
    
unsigned int alignmentedBytesPerRow = (width * 4);
    
if (!readblePixels) {
    
    readblePixels = CGBitmapAllocateData(alignmentedBytesPerRow * height);
    
    NSLog(@"alloced readablepixels");
    
}
    
unsigned int bytesPerRow = surface.bytesPerRow;
    
void *pixels = surface.baseAddress;
    
for (unsigned int j = 0; j < height; j++) {
    
    memcpy(readblePixels + alignmentedBytesPerRow * j, pixels + bytesPerRow * j, bytesPerRow);
    
}
    

    
pFrameRGB->data[0] = readblePixels; // I guess here is what I am doing wrong.
    
pFrameRGB->data[1] = NULL;
    
pFrameRGB->data[2] = NULL;
    
pFrameRGB->data[3] = NULL;
    

    
pFrameRGB->linesize[0] = pCodecCtx->width;
    
pFrameRGB->linesize[1] = 0;
    
pFrameRGB->linesize[2] = 0;
    
pFrameRGB->linesize[3] = 0;
    

    

    
sws_scale (img_convert_ctx, pFrameRGB->data, pFrameRGB->linesize,
    
       0, pCodecCtx->height,
    
       pFrameYUV->data, pFrameYUV->linesize);  

    Please help me out.

    Thanks,

    Raghu
