• what is the simplest video librery to use in visual studio c [on hold]

  9 mai 2017, par 0xPwn

  I’m looking to build a simple video player in c , visual studio.

  i’m want to change part’s of the movie while loading it to memory so it’s have to be low level enough for this.

  my first choice was ffmpeg+sdl , the problem is that i downloaded the dev version from ffmpeg website and i get dll.a and .def with the .lib , windows don’t run the exe i make from visual studio because he doesn’t found the dll’s (they are dll.a), i change their names but then i got "this either don’t designed to run on windows..." , i try to use the dll’s from the "shared" package , but i get corruption ...

  so what is my outer options ?
  (if any one know how to solve the above problem i really appreciate it).

  (i have to be able to make an .exe 32bit, don’t have to be with visual studio
  it’s supposed to be low level enough to allow me change parts of the video in
  real time).

• Can't compile dll from C++ project - Visual Studio

  19 mai 2017, par FlowRyan

  I’m trying to play a RTSP stream in Unity 5.

  For that I found a RTSP-plugin for Unity on Github that I want to try, but unfortunatelly it comes with no Readme or installation guide whatsoever.

  So far I found out that I’m dealing with a C++ Visual Studio project that needs to be compiled into a DLL in order to add it to Unity. But when I try to build the project I get the following Error for the header file "ffmpegenv.h" :

  Error C1083 Cannot open include file : ’libavutil\opt.h’ : No such file or directory - (Screenshot)

  Here’s the code from the header file

  #pragma once
  
  
  
  //=============================
  
  // Includes
  
  //-----------------------------
  
  // FFMPEG is writen in C so we need to use extern "C"
  
  //-----------------------------
  
  extern "C" {
  
      //#define INT64_C(x) (x ## LL)
  
      //#define UINT64_C(x) (x ## ULL)
  
  
  
  #include 
  
  #include <libavutil></libavutil>mathematics.h>
  
  #include <libavformat></libavformat>avformat.h>
  
  #include <libswscale></libswscale>swscale.h>
  
  #include <libswresample></libswresample>swresample.h>
  
  #include <libavutil></libavutil>imgutils.h>
  
  #include <libavcodec></libavcodec>avcodec.h>
  
  
  
  }

  I’m aware that the header includes source code from the FFmpeg libraries which doesn’t come with the plugin i’m trying to compile. However when I manually copy the referenced libraries into the project folder, it won’t build either.

  How I can I get the plugin to compile ? What am I missing ?

  Thanks in advance

  P.S. : I’m using Visual Studio Community 2017 with C++ support and Win 10 SDK as well as Win 8.1 SDK.

  }

  I’m aware that the header includes source code from the FFmpeg libraries which doesn’t come with the plugin I’m trying to compile. So I downloaded the FFmpeg source code from their GitHub page and copied all the code files (with its original folder structure) inside the plugin’s project folder.

  However when I then try to compile the plugin, it still doesn’t find the #includes an shows the same error as mentioned above.

  How I can I get the plugin to compile ? What am I missing ?

  Thanks in advance
