  • Supporting all media types

    13 avril 2011, par

    Unlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

  • 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) (...)

  • Les statuts des instances de mutualisation

    13 mars 2010, par

    Pour des raisons de compatibilité générale du plugin de gestion de mutualisations avec les fonctions originales de SPIP, les statuts des instances sont les mêmes que pour tout autre objets (articles...), seuls leurs noms dans l’interface change quelque peu.
    Les différents statuts possibles sont : prepa (demandé) qui correspond à une instance demandée par un utilisateur. Si le site a déjà été créé par le passé, il est passé en mode désactivé. publie (validé) qui correspond à une instance validée par un (...)

  • 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.

Illegal instruction

  • Using ffserver to do UDP multicast streaming

    20 novembre 2015, par Catherine MacInnes

    Here’s the deal. I’m working with IPTV hardware and I need to output a bunch of demo streams. These are MPEG2 transport stream that need to be straight up UDP Multicast streams. I have an ffmpeg command that works great :

    ffmpeg -re -i /Volumes/Data/DemoVideos/GRAILrpsp.ts -acodec copy -vcodec copy -f mpegts udp://239.192.1.82:12000[ttl=1,buffer_size=2097157]

    What I would like to do is convert this into an ffserver config file instead of having to start a whole bunch of ffmpeg streams and then figuring out how to get them to loop. I’m sure I can do it with the right scripting but what a pain, isn’t that what ffserver is for ? But I can’t find any documentation on doing UDP streaming using ffserver. You can set a multicast address and port but it goes to RTP which this hardware isn’t designed for. Any help would be greatly appreciated.
