• ffmpeg .libs windows visual studio 2008

  10 mars 2018, par DM1974

  I’ve downloaded the latest version of FFMPEG dev libraries, which include all the .libs etc
  I’ve created an MFC dialogue application in visual studio 2008 and setup all the dependencies as per Use FFmpeg in Visual Studio.

  However, I’m getting the lnk2019 issue, unresolved external symbol _avcodec_register_all referenced in funtion...

  I included the extern C at the top of my programme and setup the additional included directories...

  Can anyone help please ?

  Thanks !

• ffmpeg.exe : Missing MFPlat.dll in Windows Server 2008 R2

  15 avril 2021, par Shyam Narayan

  I am using ffmpeg to convert .m3u8 playlist to single mp4 file.
I download the Windows EXE Files from http://ffmpeg.org/download.html#build-windows successfully.
But when I open the ffmpeg.exe, an error message appears that says MFPlat.dll is missing.

  


• Connect ffmpeg to Visual Studio 2008

  29 avril 2014, par user2274492

  I try to connect ffmpeg to visual c++ like this, but when I type "./configure —toolchain=msvc" I have this error :

  c99wrap cl is unable to create an executable file.

  If c99wrap cl is a cross-compiler, use the —enable-cross-compile
  option. Only do this if you know what cross compiling means.

  C compiler test failed

  config.log :

  XXXXXX ./configure : line 728 : mktemp : command not found WARNING :

  What’s the problem ? Or just send me files that you got after compilation with this (I would not have asked, but I fix this two months) :

  ./configure —toolchain=msvc

  make

  make install
