  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • 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 (...)

  • C++ Realtime OpenGL videogame streaming library

    23 août 2013, par Mufasa

    I need to select a video encoder and library to take raw RGB frames in realtime from a videogame and send them to a remote client. The remote client is sending back mouse events. Right now I have a setup where the server is using glReadPixels to read frame data, then sending information in the form of 16x16 tiles with runlength encoding that have changed since the last read. (The videogame has a lot of solid color areas). My client works to control the game. But the transmission of frames to the client, and mouse events from the client, is too slow. Both use a TCP socket to communicate.

    I'm looking into using ffmpeg or x264 to encode into H.264 video ; do you think this could reduce latency ? I'm on windows and I can't figure out how to set up x264 libraries in Visual Studio, but I have got ffmpeg libraries installed.

    Another name I have heard is live555 but I don't know much about that.

    Do you have any recommendations ?

  • x11grab : Check the XQueryPointer return value

    x11grab : Check the XQueryPointer return value

    The paint_mouse_pointer() code uses XFixes to retrieve the cursor
    
coordinates, but XFixes gives no information about which screen the
    
pointer is on ; this results in always drawing the cursor on the
    
captured screen even if the mouse pointer was on another screen.
    

    For example, when capturing from screen 1 (i.e. -f x11grab -i ":0.1")
    
the cursor was being drawn in the captured image even when the mouse
    
pointer was actually on screen 0, which is wrong and visually confusing.

  • Using libav (ffmpeg), how to decode a video file directly to a GPU texture ?

    15 janvier 2023, par GaryO

    I'm using ffmpeg's libav to decode video files on Mac. For supported codecs, it says it can use the Mac VideoToolbox framework to hardware-accelerate the decoding.&#xA;Can I get the result of that decode directly as a Metal or CoreVideo buffer or texture, in GPU memory ? My plan is to process it with compute shaders before sending it to the screen and I'd like to maximize framerate by removing CPU<->GPU transfers.

    &#xA;

    Is there an example of doing this anywhere ?
