  • 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 vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • Converting avi to mp4 (use ffmpeg library) is very slow

    7 décembre 2012, par yAnTar

    I have task - convert any video from user to mp4 format.
    I use command

    ffmpeg -i $file -vcodec libx264 -vpre ultrafast -bt 500k -acodec libfaac -ab 56k -ac 2 -s 480x320 $outputFileMp4

    I try to change options bitrate, dimensions, but spped of converting is slow - 3 mbytes convert arround 90 seconds.

    If i convert avi to flv - no problem.

  • ffmpeg slideshow on raspberry pi raspbian

    29 novembre 2017, par mysterious_guy

    i’m trying to make slideshow video from few (in this case 3) .jpgs. To do this i’m using

        ffmpeg -r 1/5 -i bat%03d.jpg -c:v libx264 -r 30 -pix_fmt yuv420p proba12.mp4

    and actually it works on windows (it plays every image for 5seconds) but on raspbian it doesnt work neither on omxplayer nor hello_video.bin (in h264).

    Here is what console shows :

    what is also strange if im trying to concatenate those files using text file and i set duration to 5 for every single file it makes different display time... in this example first one displays for 15 seconds, second one for 5seconds and the last one for 10seconds... of course this way of merging images doesnt work under raspbian either

    i’m using raspberry pi 3b with latest raspbian noobs on board

    can you guys please direct me on a solution ? im ran out of ideas... cheers

  • why ffmpeg is not working in new installation

    3 août 2013, par Hitesh Gupta

    I was working on live encoding from FFmpeg from last few days. One day I re-installed my OS and tried to run FFmpeg commands again after configuration. My publish points get in starting but could not started. Why ? Am I missing any configuration required ?

    The command I am trying to run is :

    ffmpeg -y -re -i D:\video2.mp4 -pix_fmt yuv420p -movflags isml+frag_keyframe -f ismv -threads 0 -c:v libx264 -preset fast -profile:v baseline -map 0:v -b:v:0 800k http://localhost/PPS/PublishPoint.isml/Streams(Encode
