参照[https://github.com/Intel-FFmpeg-Plugin/Intel\_FFmpeg\_plugins/wiki][https_github.com_Intel-FFmpeg-Plugin_Intel_FFmpeg_plugins_wiki]， 在linux下编译intel版本的ffmpeg时，

[root@localhost project]# git clone https://github.com/Intel-FFmpeg-Plugin/Intel_FFmpeg_plugins.git
    Cloning into 'Intel_FFmpeg_plugins'...

    [root@localhost project]# cd Intel_FFmpeg_plugins/
    
    [root@localhost Intel_FFmpeg_plugins]# git checkout origin/qsv-3.2.2 -b 3.2.2
    Branch 3.2.2 set up to track remote branch qsv-3.2.2 from origin.
    Switched to a new branch '3.2.2'

**FFMPEG 中使用 libmfx 实现 intel qsv 的硬件编码器**，如果想要编译它的硬件编码器，所以如果想要编译这个硬件编码器，你需要在加入如下的配置选项:

./configure --enable-libmfx

执行configure时遇到了以下问题：

[root@localhost Intel_FFmpeg_plugins]# ./configure --enable-libmfx
    ERROR: libmfx not found using pkg-config
    
    If you think configure made a mistake, make sure you are using the latest
    version from Git.  If the latest version fails, report the problem to the
    ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
    Include the log file "config.log" produced by configure as this will help
    solve the problem.

如何解决呢?

> (1) /opt/intel/mediasdk/include中新建文件夹mfx，并把所有.h拷贝到该文件夹中。  
> (2) mkdir -p /opt/intel/mediasdk/lib64/pkgconfig  
> (3) 建立libmfx.pc文件，内容如下:

prefix=/opt/intel/mediasdk
    exec_prefix=/opt/intel/mediasdk/
    libdir=${prefix}/lib/lin_x64/
    includedir=${prefix}/include/
    Name: libmfx
    Description: mfx
    Version: 1.0.0
    Cflags: -I${includedir} 
    Libs: -L${libdir} -lmfx -ldl -lstdc++ -lrt -lva -lva-drm
    Libs.private: -lstdc++ -ldl

并将其拷贝到以下目录:

cp libmfx.pc /opt/intel/mediasdk/lib64/pkgconfig
    cp libmfx.pc /usr/lib64/pkgconfig

(4) 添加环境变量。

在.bashrc中添加
    export MFX_HOME=/opt/intel/mediasdk/
    export PKG_CONFIG_PATH=/usr/lib64/pkgconfig/

然后再去执行configure即可。  
然后make，接着make install。

可用以下语句验证是否成功。
