  • 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 (...)

    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 (...)

  • FFMPEG - Flaky internet for streaming, fallback stream or image

    15 juillet 2016, par jonathan tan

    I am using NGINX to receive rtmp and output to hls.

    rtmp {
    
    server {
    
        listen 1935;
    
        ...
    
        application rtmp {
    
            live on;
    
            ...
    
            exec ffmpeg -re -i rtmp://127.0.0.1/rtmp/$name -threads 1 -c:a aac -ac 1 -strict -2 -b:a 64k -c:v libx264 -profile:v baseline -g 10 -b:v 300K -s 480x240 -f flv rtmp://127.0.0.1/hls/$name;
    
        }
    
        application hls {
    
            live on;
    
            hls on;
    
            hls_path /tmp/hls;
    
            ...
    
        }
    
    }
    
}

    My stream comes from Flash Media Live Encoder. But sometimes I have flaky internet because my connection comes from mobile. Sometimes internet drops for 3-5 seconds every 5 minutes. But this is enough to disrupt the stream. Is it possible for me to make it run continuously even when my FMLE is disconnected ?

    I am thinking of executing an FFMPEG from the server box to stream continuously an image as a fallback when FMLE is disconnected, then combine the 2 RTMP streams. Perhaps favoring the one from FMLE if available, and the other as fallback. But I am not sure how to combine using FFMPEG.

    Or is there another hack I can try ?

  • Speed up FFMPEG Mixing Two Audio Files slow

    21 septembre 2016, par Jeremy

    I’m working on a FFMPEG command to mix two audio input’s, combine them (layer ontop of each other), adjust their volumes, and print out to an output. On a 99 second input, it takes about 93 seconds to finish processing and on Mobile, that is way to long.

    I’ve read that I could possibly use -copy to skip reencoding the files, but am unsure of how to do this. Only one of the files are created by the user, so the second input could just be a copy. I have tried using the different presets, fast, ultrafast, and medium but still there is a time delay.

    FFMPEG Command :

    Any ideas on how to speed this up and reduce processing time ?

    EDIT : Here are my Logs from a successful mix of a recording that was 30 seconds long.
