  • Support de tous types de médias

    10 April 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 (...)

  • HTML5 audio and video support

    13 April 2011, by

    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.
    For older browsers the Flowplayer flash fallback is used.
    MediaSPIP allows for media playback on major mobile platforms with the above (...)

  • Support audio et vidéo HTML5

    10 April 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 (...)

  • configure: Use pkg-config for libdc1394 discovery

    configure: Use pkg-config for libdc1394 discovery

    Since not all systems need the libraw1394 dependency, let pkg-config
    
provide the list of libraries actually needed.
    

    The libdc1394-2.pc file has been included since version 2 (2008-01-05),
    
so it should be safe to use.

  • tag refuses to play mp4 video

    5 January 2015, by MightyPork

    I have a video I want to embed using the html5 video tag:

    I’ve converted it using ffmpeg:

    ffmpeg -i P6135199.MOV -vcodec libx264 -acodec aac helios.mp4

    FFMPEG output:

    And I try to embed it as follows:

    <video src="helios.mp4" controls="controls">Get a better browser!</video>

    However, Chrome doesn’t play the video, only offers to download it (same as it did before I converted the video). Firefox has the same problem.

    I’ve tested and other mp4 files (from my phone) play just fine.

    What’s the problem? Did I convert it wrong?

  • Problems accessing codecs with ggplot and gganimate

    19 December 2016, by noLongerRandom

    Using gganimate. Can’t figure out how to properly access functionality of ffmpeg, specifically I want to change the codec I’m using in the video file I’m outputting.

#Basic plot
    
p &lt;- ggplot(myDf, aes(x = year, y = bottom50, frame = year)) + 
    
    geom_line(color = "dodgerblue") + 
    
    geom_line(aes(y = top1), color = "darkred")

    The non-animated version gets me what I want:

    enter image description here

    And I get an animation version output to video with:

    gganimate(p, interval = .1, title_frame = FALSE, "income.mp4")

    That’s fine, but I want to change some the output parameters, specifically: alter the dimensions, the frame rate, and use a different codec.

    # change some of the options
    
ani.options(ani.height = 1080, ani.width = 1920, 
    
            interval = 0.04166667, other.opts = "-vcodec qtrle -f mov")
    
# re-animate
    
gganimate(p, title_frame = FALSE, "income.mov")

    That gives me the following error:

    Error in animation_saver(saver, filename) : 
    
  Don't know how to save animation of type mov

    I’m using ’.mov’ as my file extension because I’m trying to change to the Animation codec (so it’s no longer a .mp4 wrapper). I’ve got ffmpeg installed, so this is probably a syntax issue. But the documentation isn’t very clear here; gganimate doesn’t have any documentation on changing codecs (or outputting any video besides an mp4), and the animation package is light on specifics as well.
