FFmpeg detailed instructions for compiling under windows

MinGW: A free-to-use and free-to-publish Windows-specific header file and a collection of import libraries using the GNC toolset, allowing you to generate local Windows programs without the need for a third-party C runtime

MinGW, minimalist GNU for Windows. It is a collection of header files and port libraries that allow people to use GCC to generate WINDOWS32 programs without a third-party dynamic-link library.

The MinGW was developed to provide a GNU-compliant GNU working environment for those who do not like to work on the Linux (FreeBSD) operating system and remain in Windows.

So, using MinGW, we can use the GNU Program development tool just like under Linux.

Minimal GNU (POSIX) system on Windows, is a small GNU environment, including basic bash,make and so on. is the best GNU environment under Windows.

---------------------------------------Build-------------------------------------------------

Thanks to the development of the software industry, it makes it easier for novices to learn and build a running environment.

Originally built Mingw+msys environment is a troublesome thing, but the new version of the MinGW direct installation can be used. Below is Wingw's Web page http://www.mingw.org/wiki/InstallationHOWTOforMinGW. Download the latest version of MinGW in the box to build the Mingw+msys environment directly.

The following minor modifications, in order to implement the FFmpeg compilation.

3) Modify "Msys.bat"
Open X:\msys\msys.bat with a text editor, because you intend to compile the program with msvc++, you need a. lib file to link to the FFmpeg library, and these. lib files can be generated using the LIB command in Microsoft's toolchain. For this reason, Microsoft's Visual Studio or Visual C + + must already be installed on the machine. Add the following line to the front of the Msys.bat and replace the path with the actual path Vcvars32.bat on the machine, such as my D:\Program Files\Microsoft Visual Studio. NET 2003\vc7\bin, So we add:
Call "D:\Program Files\Microsoft Visual Studio. NET 2003\vc7\bin\vcvars32.bat"

4) System Integration
Copy X:\msys\etc\fstab.sample to X:\msys\etc\fstab and open X:\msys\etc\fstab Edit with a text editor. (You need to use an editor that supports UNIX line-wrapping style, such as notepad++), take this line:
X:/mingw/mingw
Switch
X:/msys/mingw/mingw

Well, the environment is set up. Enter the compile ffmpeg phase.

--------------------------------------Compile--------------------------------------------------

3. Compile, get FFmpeg library (header file, lib, and DLL)

Start Msys with Msys.bat in the Msys installation directory, and a command-line window will appear, which is a RXVT program running bash, such as:

Figure 2

This is a Linux-like shell and runs on windows, like using a real Linux shell. However, use this shell to be aware of:
→ The directory name is split with a forward slash instead of the backslash used by Windows (for example, "D:/ffmpeg" rather than "D:\ffmpeg").
→ The drive letter (e.g. "C: \") can be accessed from the root directory (like this "/C/").
→ If there are spaces in the file name or directory name, you must enclose it in double quotation marks (such as "/c/program Files" with double quotes).
The following switch to the directory that holds the FFmpeg source code (if your code is D:\ffmpeg after extracting it), by typing: "Cd/d/ffmpeg".
Next, to configure FFmpeg, select the libraries that are included in the compilation, first enter:
./configure--enable-shared--disable-static--enable-memalign-hack
The--enable-memalign-hack option is required for ffmpeg to compile successfully on Windows, and after the configuration is complete, it will return to the command prompt and see the screen shown:

Figure 3

If there is no error, you can "make" has the basic function of the ffmpeg, after the prompt input: made.
The compilation process will last for a long time. If everything is OK, the end will return to the prompt and have the following output screen at the end of the final compilation:

Finally get compile-generated FFmpeg library (header file, Lib,dll)

After the prompt, enter: make install.

After execution, several files are generated under the local folder in the Msys directory. Directories such as:

4. Under VC configuration (this refers to how to call the FFmpeg library in the VC), test

VC Environment Configuration: (If the directory is shown)

Method of course, like other additional libraries, one is to set the VC global include path for you E:\msys\local\include, set the VC global Lib path to E:\msys\local\bin, increase the operating system of a path

E:\msys\local\bin. The other is to set the path of the Lib and include for a project. Add a pointer to the corresponding address above. This I do not say in detail, presumably play VC know.

First build a VC console project, and then copy the E:\FFMPEG\LIBAVCODEC\API-EXAMPLE.C (FFmpeg's storage directory) to the project you built. then renamed Api-example.cpp. Compile. You will find a header file. At this point you will need to copy the inttypes.h,stdint.h,_mingw.h three files from the E:\msys\mingw\include (include in the MinGW installation directory) to E:\msys\local\ Include (Include in the directory of your FFmpeg library). There are still many mistakes in compiling.

1. Need to #define __RESTRICT__ in Inttypes.h __restrict

2. If a long long error is changed to __int64

3. c->time_base.den= (avrational) {1,25}; Change to C->time_base.num = 1; C->time_base.den = 25;//

4. The top header file is defined as follows:

#include <math.h>//Note this, or you'll see a bug in the math template

#include <stdlib.h>

#include <stdio.h>

#include <string.h>

extern "C"

{

#ifdef HAVE_AV_CONFIG_H

#undef Have_av_config_h

#endif

#include <libavcodec\avcodec.h>

#include <libavutil\mathematics.h>

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

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

}

The final compilation should be no error. Because some of the test video files are not, so the code does not show any effect. Using one of the code above, just to test it, and then tell us what we need to do with the FFmpeg library we've compiled.

(Most of the above is reproduced in the space http://apps.hi.baidu.com/share/detail/20685063, thanks to his selfless dedication)

Objective

This article refers to a large amount of information on the Internet, collated, and verified by practice, the last updated March 11, 2010. In addition I use development tools for Delphi, will not VC, so there is no compilation of VC-related LIB library parts.

In this paper, the Mingw+msys environment path is assumed to be C:\MinGW and C:\MSYS, and for the Pure manual installation, that is, download the corresponding compression package, directly extracted to the corresponding directory.

"Introduction" FFmpeg

http://www.ffmpeg.org

FFmpeg is a complete solution for recording, converting, and streaming audio and video, including a set of leading audio and video codec libraries called Libavcodec. FFmpeg, although developed under the Linux platform, can be compiled under most operating systems, including Windows.

MinGW

http://www.mingw.org

The compilation environment required to compile FFmpeg under Windows is MinGW, which is the minimalist GNU for Windows abbreviation. The MinGW contains the Windows platform header files, GCC, and some GNU tools.

MSYS

Http://www.mingw.org/wiki/msys

Msys is the MinGW shell environment and is the abbreviation for minimal system. Msys provides a number of development tools, such as make.

Extract the above compressed packets sequentially into the same directory, e.g. extract to C:\MinGW

Copying or renaming the following files is actually removing the SJLJ suffix:

From C:\MinGW\bin\gcc-sjlj.exe to Gcc.exe
