  • Librairies et logiciels spécifiques aux médias

    10 décembre 2010, par

    Pour un fonctionnement correct et optimal, plusieurs choses sont à prendre en considération.
    Il est important, après avoir installé apache2, mysql et php5, d’installer d’autres logiciels nécessaires dont les installations sont décrites dans les liens afférants. Un ensemble de librairies multimedias (x264, libtheora, libvpx) utilisées pour l’encodage et le décodage des vidéos et sons afin de supporter le plus grand nombre de fichiers possibles.

  • Capture cctv camera with iphone application using IP

    3 juin 2014, par Bittu

    I want to develop a cctv camera app and I don’t know what steps I need to take.
    i have the data below for connecting cctv camera :

    • Ip address
    • port ID
    • user name
    • password

    i checked live555 and RTMPStreamPublisher demo from here, but i don’t know where I should start. i also read that i should use the ffmpeg framework.

    What I want is an app similar to kView on itunes. This app is able to stream a cctv camera feed with the above configuration detials

    Does anyone know what direction I need to go in ? Is there a demo or open-source app that accomplishes this ?

  • How to work with data received from streaming services in my Java application ?

    24 novembre 2020, par gabriel garcia

    I'm currently trying to develop an "streaming client" as a way to organize multiple stream services (twitch, yt, mitele...) in a single desktop application written in Java.

    


    It basically relies on streamlink (which relies in ffmpeg) thanks to all it's features so my project could be defined as a frontend for streamlink.

    


    Straight to the point, one of the features I'd like to add it is the option to programatically record streams in the background and showing this video stream to the user when it's requested. Since there's also the possibility that the user wants to watch the stream without recording it, I'm forced to work with all that byte-like data sent from those streaming sources.

    


    So, the problem is basically that I do not know much about video coding/decoding/muxing/demuxing nor video theory like container structure, video formats and such.

    


    But the idea is to work with all the data sent from the stream source (let's say twitch, for example), read this bytes (I'm not sure what kind of information is sent to the client nor format) from the java.lang.Process's stdout and then present it to the client.

    


    Here's another problem : I don't know how to play video streams in JavaFX and I don't think it's even supported right now. So I would have to extract each frame and sound associated from the stdout and show them to the user each time a new frame is received (oups, another problem since I don't know when does each frame starts/ends since I'm reading each stdout's line).

    


    As a summary :

    


      

    • What kind of data am I receiving from the streaming source ?

      • 


    • How can I know when does each frame starts/stops ?

      • 


    • How can I extract the image and sound from each frame ?

      • 


    


    I hope I'm not asking too much and that you could shed some light upon my darkness.
