本文详细介绍了如何在OpenCV 4.1.1中配置和使用FFMPEG，包括修改cmake文件、下载指定版本的FFMPEG库及其哈希值验证，以及在特定目录下放置所需文件的具体步骤。

第一步：
1.1 打开D:\opencv4.1.1\opencv\sources\3rdparty\ffmpeg\ffmpeg.cmake文件
如下所示：

# Binaries branch name: ffmpeg/master_20190616
# Binaries were created for OpenCV: 7b099e0fe2d929e55d6705b6ad510c2c9081606b
ocv_update(FFMPEG_BINARIES_COMMIT "998718df34e35ea0fa429724875fc3900faa266f")#FFMPEG_BINARIES_COMMIT后面数字加字母的一串字符串即998718df34e35ea0fa429724875fc3900faa266f就是下面${FFMPEG_BINARIES_COMMIT}的内容，根据自己情况进行修改
ocv_update(FFMPEG_FILE_HASH_BIN32 "f03b47fb809edd2e06b6db135cbd3e49")#opencv_videoio_ffmpeg.dll的哈希值
ocv_update(FFMPEG_FILE_HASH_BIN64 "5c4571459570c288d874704244c428b5")#opencv_videoio_ffmpeg_64.dll的哈希值
ocv_update(FFMPEG_FILE_HASH_CMAKE "f710891525a04586d565d0e700e62a9c")#ffmpeg_version.cmake哈希值

function(download_win_ffmpeg script_var)
  set(${script_var} "" PARENT_SCOPE)

  set(ids BIN32 BIN64 CMAKE)
  set(name_BIN32 "opencv_videoio_ffmpeg.dll")#opencv_videoio_ffmpeg.dll加在下面https://raw.githubusercontent.com/opencv/opencv_3rdparty/${FFMPEG_BINARIES_COMMIT}/ffmpeg/最后面
  set(name_BIN64 "opencv_videoio_ffmpeg_64.dll")#同上
  set(name_CMAKE "ffmpeg_version.cmake")#同上

  set(FFMPEG_DOWNLOAD_DIR "${OpenCV_BINARY_DIR}/3rdparty/ffmpeg")

  set(status TRUE)
  foreach(id ${ids})
    ocv_download(FILENAME ${name_${id}}
               HASH ${FFMPEG_FILE_HASH_${id}}
               URL
                 "$ENV{OPENCV_FFMPEG_URL}"
                 "${OPENCV_FFMPEG_URL}"
                 "https://raw.githubusercontent.com/opencv/opencv_3rdparty/${FFMPEG_BINARIES_COMMIT}/ffmpeg/"#下载链接一部分，其中${FFMPEG_BINARIES_COMMIT}和上面的FFMPEG_BINARIES_COMMIT后面数字加字母的一串字符串即998718df34e35ea0fa429724875fc3900faa266f相对应
               DESTINATION_DIR ${FFMPEG_DOWNLOAD_DIR}
               ID FFMPEG
               RELATIVE_URL
               STATUS res)
    if(NOT res)
      set(status FALSE)
    endif()
  endforeach()
  if(status)
    set(${script_var} "${FFMPEG_DOWNLOAD_DIR}/ffmpeg_version.cmake" PARENT_SCOPE)
  endif()
endfunction()

if(OPENCV_INSTALL_FFMPEG_DOWNLOAD_SCRIPT)
  configure_file("${CMAKE_CURRENT_LIST_DIR}/ffmpeg-download.ps1.in" "${CMAKE_BINARY_DIR}/win-install/ffmpeg-download.ps1" @ONLY)
  install(FILES "${CMAKE_BINARY_DIR}/win-install/ffmpeg-download.ps1" DESTINATION "." COMPONENT libs)
endif()

ocv_install_3rdparty_licenses(ffmpeg license.txt readme.txt)

下面是ffmpeg总的下载链接：

https://raw.githubusercontent.com/opencv/opencv_3rdparty/998718df34e35ea0fa429724875fc3900faa266f/ffmpeg/opencv_videoio_ffmpeg.dll
https://raw.githubusercontent.com/opencv/opencv_3rdparty/998718df34e35ea0fa429724875fc3900faa266f/ffmpeg/opencv_videoio_ffmpeg_64.dll

将ffmpeg下载下来的文件放在D:\opencv4.1.1\opencv\sources\.cache下面,根据自己的路径进行修改，没有.cache这个文件夹就自己新建一个，其具体格式如下所示

ippicv的D:\opencv4.1.1\opencv\sources\3rdparty\ippicv\ippicv.cmake按照ffmpeg进行修改，其中是下载ippicv_2019_win_intel64_20180723_general.zip还是ippicv_2019_win_ia32_20180723_general.zip是根据你cmake平台选择win32还是x64来的，实在不知道就都下载下载，按照ffmpeg来进行。其具体格式如下所示

cmake之前自己新建sources/.cache文件夹下面的文件

D:\OPENCV4.1.1\OPENCV\SOURCES\.CACHE

说明：
5c4571459570c288d874704244c428b5-opencv_videoio_ffmpeg_64.dll
其中5c4571459570c288d874704244c428b5为opencv_videoio_ffmpeg_64.dll的哈希值

第一次config之后需要需要将face_landmark_model下载下来D:\opencv_contrib-4.1.1\modules\face\CMakeLists.txt，其下载方法参照ffmpeg方式下载，其具体格式如下所示，其中xfeatures2d文件夹不需要构建第二次config自己创建和下载的，这个没有被墙，下载速度还可以的
