With FFmpeg you can either:
- use pre-built .lib/.dll files and your binary produced with Visual Studio will be dependent on av*.dll files
- compile FFmpeg from source code into static libraries using non-Microsoft compiler, and then link to your Visual Studio project (mind the LGPL/GPL license in this case)
You built your project as per item 1 above. You have to use and redistribute the av*.dll dependent files with your binary to have it working.
"Static" on Zeranoe means that libraries are statically linked into binaries like ffmpeg.exe
. Do not confuse this with static .lib
libraries that link into your binary. Zeranoe does not provide such.
On Zeranoe you will find archives like this:
- "Shared" ffmpeg-20120726-git-236ecc3-win32-shared.7z:
bin/avcodec-54.dll
bin/avutil-51.dll
- etc
- "Dev" ffmpeg-20120726-git-236ecc3-win32-dev.7z:
lib/avcodec.lib
lib/avutil.lib
"Shared" archive has FFmpeg built with dynamic link to DLL libraries. "Dev" archive has lib files which you can use in your project to link to them as well in a way that ffmpeg.exe does in shared archive.
So, your Visual Studio project can be as simple as this (browse full source here):
extern "C"
{
// NOTE: Additional directory ..zeranoe.comdevinclude gets to the files
#include "libavcodecavcodec.h"
}
// NOTE: Additional directory ..zeranoe.comdevlib gets to the files
#pragma comment(lib, "avcodec.lib")
// NOTE: Be sure to copy DLL files from ..zeranoe.comsharedin to the directory of
// the FFmpegApp.exe binary
int _tmain(int argc, _TCHAR* argv[])
{
_tprintf(_T("Trying avcodec_register_all... "));
avcodec_register_all();
_tprintf(_T("Done.
"));
return 0;
}
You will extract "Dev" archive into dev
subdirectory of Visual Studio project and you will add devinclude
on the additional include path. This will be sufficient to build the binary, and it will be dependent on av*.dll
:
This is when you extract the "Shared" archive, and copy DLLs from its bin
to the directory of your binary. And your app will work from there:
C:FFmpegAppRelease>FFmpegApp.exe
Trying avcodec_register_all... Done.
20 Jan 2016 UPDATE: The project in repository is upgraded to Visual Studio 2013 (older VS 2010 code) and checked against current Zeranoe builds. The sample and instructions remain in good standing.
Note that Win32
builds in Visual Studio assume that you use 32-bit files from Zeranoe. To build 64-bit version, download respective files and set up Visual C++ project respectively, to build x64
(or, the best, download both, set up both configurations and configure include/lib paths respectively). Failure to match bitness would result in error, mentioned in the comments below.
20 Jul 2021 UPDATE: (pulled from comments below) Zeranoe builds are no longer available. A good and officially endorsed alternative is Windows builds by BtbN. You will need a (...)-win64-gpl-shared.zip
or (...)-win64-lgpl-shared.zip
file for this tutorial.
