  • 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.

  • Segmentation Fault error when trying to compare two videos with pHash library and its ruby bindings

    10 juillet 2014, par anado1771

    I have set up my system with the latest ffmpeg and pHash libraries (ffmpeg-2.2.1 and pHash-0.9.6) as well as the pHash ruby gem (https://github.com/toy/pHash).

    I am using ruby and attempting to compare two video files like this :

    require 'phash/video'
    

    
video1 = Phash::Video.new('video1.mp4')
    
video2 = Phash::Video.new('video2.mp4')
    

    
video1 % video2

    Executing this script results in a Segmentation fault :

    ..../gems/pHash-1.1.4/lib/phash/video.rb:20: [BUG] Segmentation fault
    
ruby 1.9.3p545 (2014-02-24 revision 45159) [x86_64-darwin13.1.0]

    It appears that the crash happens in the ph_dct_videohash function which is part of the pHash library. The function is in file pHash.cpp. I am copying it here in case it would make sense to someone :

    ulong64* ph_dct_videohash(const char *filename, int &amp;Length){
    

    
    CImgList *keyframes = ph_getKeyFramesFromVideo(filename);
    
    if (keyframes == NULL)
    
    return NULL;
    

    
    Length = keyframes->size();
    

    
    ulong64 *hash = (ulong64*)malloc(sizeof(ulong64)*Length);
    
    CImg<float> *C = ph_dct_matrix(32);
    
    CImg<float> Ctransp = C->get_transpose();
    
    CImg<float> dctImage;
    
    CImg<float> subsec;
    
    CImg currentframe;
    

    
    for (unsigned int i=0;i &lt; keyframes->size(); i++){
    
    currentframe = keyframes->at(i);
    
    currentframe.blur(1.0);
    
    dctImage = (*C)*(currentframe)*Ctransp;
    
    subsec = dctImage.crop(1,1,8,8).unroll('x');
    
    float med = subsec.median();
    
    hash[i] =     0x0000000000000000;
    
    ulong64 one = 0x0000000000000001;
    
    for (int j=0;j&lt;64;j++){
    
        if (subsec(j) > med)
    
        hash[i] |= one;
    
        one = one &lt;&lt; 1;
    
    }

    delete C;
