• calling ffmpeg.exe in visual studio c++

  14 juillet 2015, par lokc261

  I am just a newbie to c++.
  I’m trying to use FFmpeg in a C++ project in Visual Studio 2012, by calling the ffmpeg.exe file inside it.

  This is what I tried so far :

  //FFMPEG CALLING
  
  char ffmpeg2[BUFSIZ];
  
  strcpy(ffmpeg2,"..\bin\ffmpeg.exe");
  
  strcat(ffmpeg2,"-f s16le -ar 8K -ac -ss");
  
  strcat(ffmpeg2,buffers);    //string hh:mm:ss
  
  strcat(ffmpeg2,"-t");
  
  strcat (ffmpeg2,buffer);    //string hh:mm:ss
  
  strcat(ffmpeg2,"-i ..\\rec.pcm ..\Desktop\newFolder\filename");
  
  if(system(ffmpeg2) !=0) 
  
  {
  
      ft =fopen("ffmpeg_err.txt","a");
  
      fprintf( ft,"my command failed...\n" );
  
      fclose(ft);
  
  }
  
  else
  
  {system(ffmpeg2);}

  It keep producing the my command fail in the text file.
  Do you guys have any hint on how to fix it.

• Problem with Linking FFMPEG Libraries in Visual Studio on Windows 10 [closed]

  14 mars 2024, par Dentricky73

  I'm facing an issue while trying to link FFMPEG libraries in Visual Studio on a Windows 10 OS. Specifically, Visual Studio seems to locate the headers correctly, but encounters difficulties in finding the associated libraries. Initially, I attempted to compile the FFMPEG SDK myself, but encountered problems with the library extensions, which ended with a Linux .o file instead of a Windows .lib. Subsequently, I downloaded a prebuilt version from here, but I'm still encountering errors.

  


  In Visual Studio 2022, I've configured the following settings :

  


  


  Property > Configuration Properties > C/C++ > General > Additional Include Directories
C :\cmder\c++SDK\ffmpeg\include

  


  


  


  Property > Configuration Properties > Linker > General > Additional Library Directories
C :\cmder\c++SDK\ffmpeg\lib

  


  


  


  Property > Configuration Properties > Linker > Input > Additional Dependencies
avcodec.lib, avdevice.lib, avfilter.lib, avformat.lib, avutil.lib, postproc.lib, swresample.lib, swscale.lib

  


  


  Despite these configurations, Visual Studio fails to locate the FFMPEG libraries during the linking process. Could someone please provide guidance on how to resolve this issue and correctly link the FFMPEG libraries in Visual Studio on Windows ? Any help or insights would be greatly appreciated.

  


  Specific Issues Encountered :

  


  During the compilation and linking process in Visual Studio 2022, I encountered the following errors :

  


  Error 1 : A value of type "const AVCodec *" cannot be used to initialize an entity of type "AVCodec *".
Error 2 : Identifier "av_free_packet" is undefined.
Error 3 : Class "AVStream" has no member "codec".
Error 4 : Class "AVFrame" has no member "owner".
Despite configuring the project settings to include the correct include directories and library dependencies, these errors persist.

  


  Why Previous Attempts Didn't Meet My Needs :

  


  My previous attempts to resolve these issues were unsuccessful because I couldn't pinpoint the root cause of the compilation and linking errors. While I ensured that the include directories and library dependencies were correctly configured in Visual Studio, the errors persisted, indicating that there may be underlying issues with the setup or compatibility between the FFMPEG SDK and Visual Studio environment.
