  • 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) (...)

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.

  • Support audio et vidéo HTML5

    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
    Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...)

  • FFMPeg stuck while processing a video

    15 juin 2017, par Muhammad Umar

    I am trying to add slow motion to an FFMPEG video in android

    On my terminal original query i use is

    ffmpeg -i soon.mp4 -filter_complex "[0:v]setpts=0.5*PTS[v];[0:a]atempo=2.0[a]" -map "[v]" -map "[a]" output.mp4

    Here is my code in android,

        String cmd = "/data/data/PACKAGE_NAME/files/ffmpeg -i "+ videoFileName +" -filter_complex [0:v]setpts=0.5*PTS[v];[0:a]atempo=2.0[a] -map [v] -map [a] " + file.getAbsolutePath();

    In Android , i have only removed quotation marks since ffmpeg is not recognising these.

    When i exceute FFMPEG,
    following happens

    The video size 480x640 is correct, but it only lasts 2 seconds, only contains the first image 1.jpg, please tell me how I can solve this problem ?

  • Issues mapping multiple Axis RTSP streams using FFMPEG

    26 juin 2017, par Alex R

    I have an application built in C# that leverages FFMPEG to map 3 h264 RTSP streams from Axis cameras along with a gdigrab screen recording and saves everything to a file using this command :

     -rtsp_transport tcp -i rtsp://192.168.1.200/axis-media/media.amp -rtsp_transport tcp -i rtsp://192.168.2.200/axis-media/media.amp -rtsp_transport tcp -i rtsp://192.168.3.200/axis-media/media.amp -r 30 -f gdigrab -framerate 1 -i title="MainWindow"  -c copy -map 0 -vcodec copy -map 1 -metadata title="6-26-2017-4-22-PM- TEST VIDEO" -vcodec copy -map 2 -vcodec copy -map 3 -vcodec h264 -preset ultrafast C:\Users\*USERNAME*\6-26-2017-4-22-PM-cam1comb.mkv

    The issue that I’m having is that the Axis camera streams are out of sync with each other, with approximately a 3 second delay between the three streams. When I test the FFMPEG command with all inputs changed to this stream rtsp://mpv.cdn3.bigCDN.com:554/bigCDN/_definst_/mp4:bigbuckbunnyiphone_400.mp4 as well as the screen grab however, everything works perfectly.
