  • 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".

  • Bash Script to get info from ffprobe

    14 novembre 2016, par Alan

    I am trying to create a script to process videos, but I was hoping to get bit_rate, width, and height info from the incoming files so I could better tune the output. The script works when I do the files one at a time, but when I put it into a loop all of a sudden I don’t get any info.

    So this works :

    #!/bin/bash
    
eval $(ffprobe -v quiet -show_format -of flat=s=_ -show_entries stream=height,width,nb_frames,duration,codec_name input.mp4);
    
width=${streams_stream_0_width};
    
height=${streams_stream_0_height};
    
bitrate=$((${format_bit_rate}/1000));
    
echo $width,$height,$bitrate;

    This doesn’t when executed from find ./ -type f -regex ".*\.\(mkv\|mp4\|wmv\|flv\|webm\|mov\|avi\)" -print0 | xargs -0 /root/newbatch.sh

    for i; do
    
eval '$(ffprobe -v quiet -show_format -of flat=s=_ -show_entries stream=height,width,nb_frames,duration,codec_name $i)';
    
width=${streams_stream_0_width};
    
height=${streams_stream_0_height};
    
bitrate=${format_bit_rate};
    
kbitrate=$((bitrate/1000));
    
echo $i,$width,$height,$kbitrate;
    

    
done

    I also get an error with the math of bitrate in the loop, but even when I comment it out I still get no results. Since it works one at a time, I am assuming the problem is a bash scripting and nothing to do with ffmpeg / ffprobe.

    That being said, I can do this :

    echo $i,$width,$height,$bitrate;

    and get back

    ./file1.mkv,,,
    
./file2.mkv,,,
    
./file3.mkv,,,
    
./file4.mkv,,,

    So it does get some info back, but it loses the info from the eval statement.

  • What is the difference between ffmpeg -thread and ffmpeg-mt ?

    11 septembre 2011, par Saptarshi Biswas

    Post ffmpeg-mt's merge with ffmpeg...

    March 21, 2011

    Today FFmpeg-mt, the multithreaded decoding branch, has been merged into FFmpeg. This has been a long awaited merge, and we would like to thank Alexander Strange for his patience and hard work.

    ... what is to be expected of ffmpeg -thread usage ? Is this an under-the-hood transition or are ffmpeg users supposed to move their code to ffmpeg-mt to leverage multi-cores ?
