  • 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) (...)

  • HTML5 audio and video support

    13 avril 2011, par

    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 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 (...)

  • How to make video loop properly ?

    28 mai 2019, par woopwoop399

    I want to play this video in a loop https://www.nicovideo.jp/watch/sm16617386 . I want to play an mp4 file in such a way, that whenever it gets to some point in the video (let’s say, 30.3 seconds), it will loop back (to for example 5.85 seconds).

    I tried to add this code in ffplay.c , it didn’t work well enough, I can hear the transition. I guess seeking isn’t fast enough, or audio needs to be looped in an independant way somehow.

    static void video_refresh(void *opaque, double *remaining_time)
    
{
    
   (original code here...)
    
    time = get_master_clock(is);
    
    if (isnan(time))
    
        time = (double)is->seek_pos / AV_TIME_BASE;
    
    if (time > jump_when) {
    
        stream_seek(is, (int64_t)(6.0 * AV_TIME_BASE), (int64_t)(0.0 * AV_TIME_BASE), 0);
    
    }
    
}

    My current plan is to just dig into ffmpeg, understand how video and audio decoders work, and savestate/loadstate the decoders.

  • Python OpenCV real-time blurring with saving to output

    10 janvier 2024, par Oleg Novosad

    I have a live video stream via RTSP from my IP camera. I want to blur faces on that stream and output for mobile usage (HLS, H.264, etc). All this should ideally happen in real-time — with the minimum of resources consumed. I plan to deploy this later to some cloud, so the less money I spend on resources the better.

    


    Currently I have a working solution like so :

    


      

    • I capture video using OpenCV

      • 


    • I update every frame with Gaussian Blur and save it to some folder

      • 


    • After some amount of frames I create MP4 / AVI / whatever video and make it accessible via HTTP URL

      • 


    • All of it is running on Django for now

      • 


    


    I know I am doing something wrong, can someone suggest a better solution ?

    


  • dnn : add layer pad which is equivalent to tf.pad

    29 juillet 2019, par Guo, Yejun
    dnn : add layer pad which is equivalent to tf.pad

    the reason to add this layer first is that vf_sr uses it in its
    
tensorflow model, and the next plan is to update the python script
    
to convert tf.pad into native model.
