  • Mediabox : ouvrir les images dans l’espace maximal pour l’utilisateur

    8 février 2011, par

    La visualisation des images est restreinte par la largeur accordée par le design du site (dépendant du thème utilisé). Elles sont donc visibles sous un format réduit. Afin de profiter de l’ensemble de la place disponible sur l’écran de l’utilisateur, il est possible d’ajouter une fonctionnalité d’affichage de l’image dans une boite multimedia apparaissant au dessus du reste du contenu.
    Pour ce faire il est nécessaire d’installer le plugin "Mediabox".

  • How to output raw frequency (fft) data using ffmpeg / libavfilter

    12 janvier 2020, par Jeroen

    I’m trying to write libavfilter bindings to convert an arbitrary audio file into a raw frequency (spectrum) data to do subsequent audio analysis. Is there anything built-in ffmpeg or libavfilter to output binary frequency data, rather than a proper audio/video file ?

    FFmpeg has a few built-in filters that perform an FFT such as afftfilt and showfreqs, however these filters always convert output back to video or audio. What I need is something like the afftfilt filter, but which dumps the raw FFT data, rather than recode it back to PCM.

    Revert "avcodec/decode : copy the output parameters from the last bsf in the chain back to the AVCodecContext"

    This reverts commit f631c328e680a3dd491936b92f69970c20cdcfc7.
    

    The avcodec_parameters_to_context() call was freeing and reallocating
    
AVCodecContext->extradata, essentially taking ownership of it, which according
    
to the doxy is user owned. This is an API break and has produced crashes in
    
some library users like Firefox[1].
    

    Revert until a better solution is found to internally propagate the filtered
    
extradata back into the decoder context, or a decision is made to change the
    
API.

  • ffprobe json output not working in exec, but works in CMD

    26 novembre 2015, par Nicholas Walker

    I’ve installed ffmpeg on my windows 2008 server.

    I use this string in CMD and i get what i want to get in my

    PHP file :

     ffprobe -v quiet -print_format json -show_format -show_streams "C:\wamp\www\uploads\fc30e528b500b26a391ed4f5ed484310.mp4"

    This is my PHP function i found on another stackoverflow question, it had great feedback so i tested it.

    $file_name = 'fc30e528b500b26a391ed4f5ed484310';
    
$file_ext = 'mp4';
    
$ffprobe = 'C:\\ffmpeg\\bin\\ffprobe.exe';
    
$videoFile = 'C:\\wamp\\www\\uploads\\'.$file_name.'.'.$file_ext;
    

    
$cmd = shell_exec($ffprobe .' ffprobe -v quiet -print_format json -show_format -show_streams "'.$videoFile.'"');
    
$parsed = json_decode($cmd, true);
    
print_r($parsed);

    What is get back is nothing. I also tried using the same function i used with ffmpeg(which i got working for ffmpeg).

    $cmd = $ffprobe.' ffprobe -v quiet -print_format json -show_format -show_streams "'.$videoFile.'" 2>&amp;1';
    
echo shell_exec($cmd);

    This also brings back nothing.

    Any ideas ?
