    Puis-je poster des contenus à partir d’une tablette Ipad ?
    Oui, si votre Médiaspip installé est à la version 0.2 ou supérieure. Contacter au besoin l’administrateur de votre MédiaSpip pour le savoir

  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • flac/metaflac : Limit the size of metadata blocks

    flac/metaflac : Limit the size of metadata blocks

    Limit allow image file size to slightly less than 2^24 bytes so that
    
the file size plus extra house keeping data is strictly less that
    
2^24 bytes in size.

  • libx265 motion compensation and CU traverse

    17 juin 2016, par Ariana

    I’m trying to play with the H.265 motion compensation and search (HEVC- libx265 implementation from here : https://bitbucket.org/multicoreware/x265/downloads). I need to slightly extend the edge extension search, and fill the macro block with left-most pixels as if my sample videos are like cylinder (rightmost is connected to leftmost).

    What I need to do is basically this :

    enter image description here

    One way to do that is to modify the edge extension area (which is already in the code, in the frameFilter.cpp), and do that for rightmost and fill parts of blocks which are out with leftmost pixels. I identified the piece of code here which apparently is responsible for that. Can someone help me with implementing this feature ?

    if ((col == 0) | (col == m_frameFilter->m_numCols - 1))
    
    {
    
        // TODO: improve by process on Left or Right only
    
        primitives.extendRowBorder(reconPic->getLumaAddr(m_rowAddr), stride, reconPic->m_picWidth, realH, reconPic->m_lumaMarginX);
    

    
        if (m_frameFilter->m_param->internalCsp != X265_CSP_I400)
    
        {
    
            primitives.extendRowBorder(reconPic->getCbAddr(m_rowAddr), strideC, reconPic->m_picWidth >> hChromaShift, realH >> vChromaShift, reconPic->m_chromaMarginX);
    
            primitives.extendRowBorder(reconPic->getCrAddr(m_rowAddr), strideC, reconPic->m_picWidth >> hChromaShift, realH >> vChromaShift, reconPic->m_chromaMarginX);
    
        }
    
    }
    

    
    // Extra Left and Right border on first and last CU
    
    if ((col == 0) | (col == m_frameFilter->m_numCols - 1))
    
    {
    
        copySizeY += lumaMarginX;
    
        copySizeC += chromaMarginX;
    
    }
    

    
    // First column need extension left padding area and first CU
    
    if (col == 0)
    
    {
    
        pixY -= lumaMarginX;
    
        pixU -= chromaMarginX;
    
        pixV -= chromaMarginX;
    
    }
