• 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 ?

• how to use x264 dll in another project

  7 février 2024, par Hadi Rasekh

  I want to use x264 in my project. There is some line in the code said :

  


  `/* Application developers planning to link against a shared library version of

  


  

  • libx264 from a Microsoft Visual Studio or similar development environment

  


  • will need to define X264_API_IMPORTS before including this header.

  


  • This clause does not apply to MinGW, similar development environments, or non

  


  • Windows platforms. */`

  


  


  But I don't get this line :
define X264_API_IMPORTS before including this header

  


  We can create x264 dll by its configuration and make

  


      ./configure --enable-shared
    make


  


  but I can not use the dll in my Qt Project.

  


  I can make my own dll (in another code) and use it in the project.
But when I start to use x264 dll in my project I get the following error :

  


      C:\DataHiding\SourceCode2\GUI\DataHiding\mainwindow.cpp:10: error:
    'pulldown_frame_duration' was not declared in this scope
    qDebug() << pulldown_frame_duration[1];
             ^
