--------------------

#### 预装mingw和msys ####

MinGW : https://sourceforge.net/projects/mingw/  
安装与自己系统对应的版本

msys 我用的1.0.11 挺小的3m左右 百度有

好像还有个msys2，体积大了很多，不知道能不能用  
http://www.msys2.org/  
MSYS2 : https://sourceforge.net/projects/msys2/

#### pkg-config ####

stackoverflow : https://stackoverflow.com/questions/1710922/how-to-install-pkg-config-in-windows

#### qsv驱动 ####

官方下载windows的qsv驱动 : https://software.intel.com/en-us/media-sdk

#### libmfx ####

mfx\_dispatch : https://github.com/lu-zero/mfx\_dispatch

我用cmake编译的，改一下CMakeList.txt  
默认编译静态库改成动态库

#### ffmpeg ####

./configure --enable-libmfx --enable-encoder=h264\_qsv --enable-decoder=h264\_qsv --disable-x86asm --enable-shared --pkg-config=true --extra-cflags=-I/lib/include --extra-ldflags=-L/lib/lib

如果报错:  
`libmfx can not found`  
看下是不是ffmpeg的config.log里面配置是不是找的头文件多了一个mfx目录 类似<mfx/mfxvideo.h>  
自己建一个mfx目录即可.

–extra-cflags 写libmfx的目录

#### `由于找不到 libmfx.dll` ####

![\[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-Vazumlwc-1573015155503)(./1573012045106.png)\]][img-Vazumlwc-1573015155503_._1573012045106.png]  
把上面生成的libmfx.dll 加到windows的库路径里面.

后面就能用了.

例子 : `qsv:decode`, `qsv:scale`,`qsv:overlay`,`qsv:encode`  
`ffmpeg -protocol_whitelist "file,http,https,rtp,udp,tcp,tls" -hwaccel qsv -c:v h264_qsv -i 1080p.h264 -lavfi 'scale_qsv=960:540 [s0];color=black:r=30:size=1920x1080:sar=1/1, hwupload=extra_hw_frames=64,format=qsv [b0];[b0][s0] overlay_qsv=x=0:y=0' -c:v h264_qsv out.264`
