ffmpeg交叉编译使用跨平台库版本.doc

Lsm 最后更新时间2012-04-19下载一、 下载 VS2010 + SP1 安装二、 下载yasm各个版本三、 下载MingW 最新,完全安装The cross-compile toolchain used to compile this FFmpeg was:MinGW-w64: /winpthreads (part of MinGW-w64)The GCC version used to compile this FFmpeg was:GCC 4.6.2: /四、 下载Msys Update 最新（不需要，可以自己手动更新）五、 下载源码SDL最新； ffmpegsource ； pthreadGC2.dll等等六、 扩展库:///projects/opencore-amr/////http:/rtmpdump.mplayerhq.hu//// /projects/opencore-amr/ /projects/opencore-amr///code//developers/x264.html///配置编译环境编译生成:1.配置 MingW下载msys.bat 启动文件 C:MinGWmsys1.0使用UltraEdit打开msys.bat文件，在文件的最最前面加入如下一行： call D:Program FilesMicrosoft Visual Studio 10.0VCbinvcvars32.bat /交叉编译产生lib链接库2.配置 yasm直接把 yasm-1.1.0-win32.exe 文件名修改成：yasm.exe，并放到系统目录下：C:WINDOWSsystem32。3.编译SDL 启动Msys 主要为【SDL support yes】和SDL本地库$ cd SDL-1.2.14 /到源码文件夹$ ./configure -prefix=/usr/生成配置$ Make /编译$ make install/安装编译完成后，在C:MinGWmsys1.0的bin、include和lib文件夹下可以看到编译结果。4.编译X264 为ffmpeg使用libx264.a 静态库 和动态库两种提供方式，下面是静态库$ cd x264/到源码文件夹$ ./configure -prefix=/e/MinGW -enable-static /生成配置-prefix=/C/MinGW 安装到MingW的安装目录才是对应的系统文件夹 -prefix=/usr 安装到 msys 要$ make install/编译-安装对应ffmpeg configure检查修改5. 对媒体线程库 pthread 、lpthreadGC2 、w32threads “pthreadGC2.dll”直接拷贝到当前目录，也可放到系统目录C:WINDOWSsystem32中X264 ： configure -disable-pthread /x264默认不配置6. 编译 ffmpeg 最终库 双击“C:MinGWmsys1.0msys.bat”，启动“MinGW32”， 切换到SDL目录：D:ffmpegffmpeg-0.8.5SDL-1.2.14，切换方法如下：$ cd ffmpeg-0.8.10/到源码文件夹$ ./configure -disable-static -enable-shared -enable-gpl -enable-version3 -disable-doc -disable-ffplay -disable-ffprobe -disable-ffserver -disable-w32threads -enable-memalign-hack -enable-avisynth -enable-libx264/生成配置ffmpeg zeraone Static:-enable-gpl -enable-version3 -disable-w32threads -enable-runtime-cpudetect -enable-avisynth -enable-bzlib -enable-frei0r -enable-libopencore-amrnb -enable-libopencore-amrwb -enable-libfreetype -enable-libgsm -enable-libmp3lame -enable-libopenjpeg -enable-librtmp -enable-libschroedinger -enable-libspeex -enable-libtheora -enable-libvo-aacenc -enable-libvo-amrwbenc -enable-libvorbis -enable-libvpx -enable-libx264 -enable-libxavs -enable-libxvid -enable-zlibffmpeg zeraone Shared:-disable-static -enable-shared -enable-gpl -enable-version3 -disable-w32threads -enable-runtime-cpudetect -enable-avisynth -enable-bzlib -enable-frei0r -enable-libopencore-amrnb -enable-libopencore-amrwb -enable-libfreetype -enable-libgsm -enable-libmp3lame -enable-libopenjpeg -enable-librtmp -enable-libschroedinger -enable-libspeex -enable-libtheora -enable-libvo-aacenc -enable-libvo-amrwbenc -enable-libvorbis -enable-libvpx -enable-libx264 -enable-libxavs -enable-libxvid -enable-zlib-enable-runtime-cpudetect /Freedom版本/usr/bin -cross-prefix=i586-mingw32msvc- -arch=x86 -disable-gpl -disable-avisynth -disable-postproc -enable-runtime-cpudetect -disable-encoders -disable-muxers -disable-network -disable-devices -enable-sharedi586-mingw32msvc-pkg-config file is must be excutable.
