  • Le plugin : Gestion de la mutualisation

    2 mars 2010, par

    Le plugin de Gestion de mutualisation permet de gérer les différents canaux de mediaspip depuis un site maître. Il a pour but de fournir une solution pure SPIP afin de remplacer cette ancienne solution.
    Installation basique
    On installe les fichiers de SPIP sur le serveur.
    On ajoute ensuite le plugin "mutualisation" à la racine du site comme décrit ici.
    On customise le fichier mes_options.php central comme on le souhaite. Voilà pour l’exemple celui de la plateforme mediaspip.net :
    < ?php (...)

  • Overlay Image on moving object in Video

    10 mai 2017, par Karandeep Atwal

    I am using FFmpeg to overlay image/emoji on video by this command -

    "-i "+inputfilePath+" -filter_complex "+"[0][1]overlay=enable='between(t,"+startTime+","+endTime+")'[v1]"+" -map [v0] -map 0:a "+OutputfilePath;  

    But above command only overlay image over video and stays still.

    In Instagram and Snapchat there is New pin feature . I want exactly same ,eg blur on moving faces or as in below videos -

    enter image description here

    Here is link.

    Is it possible via FFmpeg ?

  • FFmpeg create output directory hierarchy

    23 avril 2017, par David

    Recently bought an ip-cam which outputs a RTSP stream. I’m using the segment option of FFmpeg to create 60 minute long recordings.

    I want FFmpeg to write the files to a directory based on Year/Month/Date, and write to a file Hour-Minute.mp4 For example :
    /raid1/homes/share/public/recordings/queue/bedroom/2017/04/23/13-05.mp4 for a recording started on 23 april 2017, 13:05.

    Unfortunately FFmpeg seems to not create the directory hierarchy. FFmpeg quits since the directory can not be found.

    Input #0, rtsp, from 'rtsp://192.168.1.240/unicast':

    I’ve tried not using a directory hierachy : "/raid1/homes/share/public/recordings/queue/bedroom/%Y-%m-%d_%H-%M.mp4". This works fine.

    Can FFmpeg create output directories on the go ?

  • FFMPEG build still resulting in `Illegal instruction` on raspberry pi ZERO, but not PI 2+

    17 mai 2017, par zyeek

    The process in which I do it configures the lib and ffmpeg files on the zero then move over to a pi 3 to make and install it (for speed).

    Build process :

    # x264
    
git clone git://git.videolan.org/x264.git
    
cd x264
    
sudo ./configure --host=arm-unknown-linux-gnueabi --enable-shared --disable-opencl
    
sudo make
    
sudo make install
    
sudo ldconfig
    

    
# FFMPEG
    
git clone git://source.ffmpeg.org/ffmpeg.git
    
cd ffmpeg
    
sudo ./configure --arch=armel --target-os=linux --enable-gpl --enable-libx264 --enable-nonfree
    
sudo make
    
sudo make install

    I tried following this cross compile type build but complained I was missing a C compiler, but GCC was installed. SO I just went to follow my previous method.

    Results of trying to run it :
