FFmpeg Learning (a)--compiling ffmpeg under WINDOW7

FFmpeg is an open source, free cross-platform video and audio streaming project that provides a complete solution for recording, converting, and streaming audio and video. The author will attempt to use the library to implement a complex network environment,

A streaming media server that supports the standard RTSP protocol. Due to the incompatibility of the C + + compiler provided by Visual Studio with the C99 standard, it cannot be compiled directly using msvc++, this article uses a class that is configured under Windows

Linux-like compilation of the way the environment compiled FFmpeg source code.

1. Preparatory work:

Download the following four software first.

1) Mingw-msys Bundle http://sourceforge.net/projects/mingwbundle/

2) SDL http://www.libsdl.org/download-1.2.php Note: In this environment 2.0.3 version of the source code compilation will be problematic, not recommended.

3) Yasm http://yasm.tortall.net/Download.html

4) FFmpeg http://www.ffmpeg.org/download.html

2. Install Mingw-msys bundle software

Mingw-msys bundle software also contains MinGW and MSYS, do not need to connect to the network for installation, follow the software's default installation Wizard, all the way next, the software installed.

When installed, a shortcut is generated on the desktop, pointing to the file "C:\Program Files\mingw-msys\msys.bat". Double-click to start the console, and all subsequent actions will be completed under this console.

3. Installation of SDL

Unzip the SDL source code into the F:\Work\ffmpeg-2.4\SDL-1.2.15 directory. Go to the SDL directory and execute each

./configure--prefix=/usr/local/sdl

Make

Make install

Complete the installation of SDL.

After the SDL compiles, the generated bin file, include file, and Lib file are stored in the C:\msys\1.0\local\SDL directory.

Import the SDL environment variables using the following command.

Export path= "$PATH:/usr/local/sdl/bin:/usr/local/sdl/include/sdl:/usr/local/lib"

Otherwise, the SDL support item is displayed as no when the FFmpeg configure is executed. (Note: The MinGW default root directory corresponds to the C:\msys\1.0\ directory under Windows and can be viewed through the echo $PATH)

4, Installation Yasm

The Yasm source package (in the YASM official website downloaded a long time to download, each download to half of the broken, and later in csdn downloaded) extracted to the F:\Work\ffmpeg-2.4\yasm1.2.0 directory.

Go to the Yasm directory and perform each of the following:

./configure--prefix=/usr/local/yasm

Make

Make install

and import the YASM environment variable by the following command.

Export path= "$PATH:/usr/local/yasm/bin"

5, installation FFmpeg

Extract the FFmpeg source (ffmpeg-2.4.tar.bz2) to F:\Work\ffmpeg-2.4\ffmpeg-2.4, enter the FFmpeg code directory, respectively, execute the following command:

Compile to Static library:./configure--enable-static--enable-memalign-hack or

Compile as a dynamic library:./configure--enable-shared--enable-memalign-hack

Make note: There may be similar unable to rename Ffplay.exe:reason file exists errors, which will be resolved after defender exits.

Make install

After the compilation is complete, you can see the compilation results in the bin, include, and Lib folders of C:\msys\1.0\local. A static library is a file with a suffix of. A, and a shared library is a file with a suffix of. So.
