  • Compile FFmpeg Zeranoe Build with Visual Studio 2013

    29 août 2017, par mFeinstein

    I downloaded the most recent Zeranoe dev build here, included the header files to my code, placed extern "C" around the includes, since this is a C++ project and FFmpeg is a C library, and added the libs to Visual Studio as well, and I get this linker error :

    Searching here and on Google I found many recommendations, such as to add #pragma comment(lib,...), and that the libs are static, so their order is important, and none of this helps.

    So I scratched my head even more and realized that the Zeranoe build is made with MinGW-w64, so probably it won’t link with Visual Studio. I inspected the lib using dumpbin and the symbols on the libs don’t have the underscore, so I am pretty sure it won’t work.

    The other Zeranoe builds for Windows don’t have libs, they are just plain .exe or exe + .dll.

    Will I have to make my own VS2013 build of FFmpeg to link it, or is there some alternative way ?

  • Can't link FFmpeg in Visual Studio 2013

    22 février 2016, par Sir DrinksCoffeeALot

    I’m struggling with this for past 3-4 days with barely any progress. I’ve downloaded "dev" and "shared" archives and extracted them. "Dev" archive has .lib and .h files and "Shared" has .dll files needed for running app. These are the steps that i’ve done linking-wise :

    Project -> Properties -> Configuration Properties -> VC++ Directories -> Include Directories -> ...\ dev\ include

    Project -> Properties -> Configuration Properties -> VC++ Directories -> Library Directories -> ...\ dev\ lib

    Project -> Properties -> Configuration Properties -> C/C++ -> General -> Additional Include Directories -> ...\ dev\ include

    Project -> Properties -> Configuration Properties -> Linker -> General -> Additional Library Directories -> ...\ dev\ lib

    Project -> Properties -> Configuration Properties -> Linker -> Input -> Additional Dependencies -> avcodec.lib ... swscale.lib

    And when i try to build it i get following error :

    Error 1 error LNK2019: unresolved external symbol _avcodec_register_all referenced in function _main...

    I have no idea why,somehow .lib are not getting linked or something or i’ve done something wrong. It’s getting really frustrating and ffmpeg is crucial in project that i’m working on, basicly i can’t do anything without it. So please if someone could point me in right direction i would aprreciate it very much.

    This is the example that im trying to build.

    #include 
    
extern "C"
    
{
    

    
#include "libavcodec\avcodec.h"
    
}
    

    

    
#pragma comment(lib, "avcodec.lib")
    

    
int main()
    
{
    
    printf("Trying avcodec_register_all... ");
    
    avcodec_register_all();
    
    printf("Done.\n");
    
    return 0;
    
}

    Thank you in advance.
