  • 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) (...)

  • Support audio et vidéo HTML5

    10 avril 2011

    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 (...)

  • How to combine 2 videos using either NReco ffmpeg ConvertMedia or just ffmpeg command line ?

    11 octobre 2016, par M. Ilchuk

    We have 2 videos : video1.webm and video2.webm.
    How to combine these two and get output.mp4 which contains video from video1.webm and audio from video1 and video2 ?

    Example :

    video1(audio1 in video1) + video2(audio2 in video2) = outputVideo(video1 + audio1 +audio2)

    image example

  • Use opencv to encode into flv, playable by flash player

    I've compiled ffmpeg with libx264 using configure options given at 1.

    This results in the following codecs being available in ffmpeg :

    $ ffmpeg -codecs | grep "264\|flv"

    After this, I compiled opencv. Here is partial cmake result :

    --   Video I/O:

--       codec:                    YES
    
--       format:                   YES

--     V4L/V4L2:                   /1
    
--     Xine:                       NO

    Now, using opencv's VideoWriter, I tried to encode into flv with the following FOURCC codes :
    FLV1, X264

    While the FLV1 results in a video file not playable by flash player, but playabe by vlc ; X264 produces no results at all.
    Here is the console output for X264, resulting in a 0 byte file.

    Output #0, flv, to 'd.flv' :
    Stream #0.0 : Video : [0][0][0][0] / 0x0000, yuv420p, 320x240, q=2-31, 4915 kb/s, 90k tbn, 24 tbc

    Do you see anything amiss or incorrect ?
    thanks,
