I want to compile an OpenCV that supports decoding VVC videos. I have tried multiple times but have not been successful. The specific steps are as follows: 1. Dowload [opencv-4.10.0.zip](https://codeload.github.com/opencv/opencv/zip/refs/tags/4.10.0) and [ffmpeg-master-latest-win64-gpl-shared.zip](https://github.com/BtbN/FFmpeg-Builds/releases/download/latest/ffmpeg-master-latest-win64-gpl-shared.zip) 1. Create a build directory C:/opencv/build and a cmake dirctory C:/fmpeg-master-latest-win64-gpl-shared/cmake 3. Save the cmake script (`ffmpeg-config.cmake` ) mentioned in C:/fmpeg-master-latest-win64-gpl-shared/cmake 4. use cmake-gui\_3.3.1.0,set where is the source code: C:/opencv and where to build the binaries: C:/opencv/build,then click _Configure_ 。after a while, use _Add Entry_ add **FFMPEG\_DIR** and **OPENCV\_FFMPEG\_USE\_FIND\_PACKAGE** ,which as follows: 1. List item click _Configure_ again ,after a while,Cmake output show as follows: ![CMAKE4](https://us1.discourse-cdn.com/flex020/uploads/opencv/original/2X/b/b546d1d3703f7e3e6ebcc263518bf3a388c8dcb7.jpeg) Thank you for any help you have provided ---

> [@dengfeng\_zhan](#): > > **FFMPEG\_DIR** I cannot manage to get the output you describe. I always use the command line but I have tried your approach above and the command line below without any issues > `"C:\Program Files\CMake\bin\cmake.exe" -BC:/opencv/build -Hc:/opencv -G"Visual Studio 17 2022" -DOPENCV_FFMPEG_USE_FIND_PACKAGE=ON -DFFMPEG_DIR=C:/fmpeg-master-latest-win64-gpl-shared/cmake` **Note** : The only difference in the GUI is that I add the **FFMPEG\_DIR** and **OPENCV\_FFMPEG\_USE\_FIND\_PACKAGE** variables before hitting Configure the first time. The output for FFMpeg config is then: > – Video I/O: > – FFMPEG: YES (find\_package) > – avcodec: YES (59.18.100) > – avformat: YES (59.16.100) > – avutil: YES (57.17.100) > – swscale: YES (6.4.100) > – avresample: NO > – GStreamer: NO > – DirectShow: YES > – Media Foundation: YES > – DXVA: YES Do you receive any warnings etc. in the window at the bottom before the configuration output? ---

Now I see the issue. I’m not using the latest, I’m using the ones I recommended in the post. I think you will need a different script for the latest version of FFMpeg. ---

I absolutely agree with your statement about the need for a different script for the latest version of FFMpeg.But I know nothing about how to write cmake script。This really frustrates me！ 😵‍💫 ---

The issue with the latest version is that some modules have the major version number stored in a seperate header. Adding the section below allowed me to succesfully build OpenCV against the version you linked to. I haven’t tested the build to make sure it works. > ``` > set(version_major_header_path "${FFMPEG_${component}_INCLUDE_DIR}/lib${component}/version_major.h") > if (EXISTS "${version_major_header_path}") > file(STRINGS "${version_major_header_path}" major_version > REGEX "#define *LIB${component_upper}_VERSION_MAJOR ") > string(REGEX REPLACE ".*_MAJOR *\([0-9]*\).*" "\\1" major "${major_version}") > endif() > > ``` [Modified version](https://gist.github.com/cudawarped/8abdae042d969969e41a9905cb85cc30) below. > **ffmpeg-config.cmake** > > ```auto > #[==[ > Provides the following variables: > > * `FFMPEG_INCLUDE_DIRS`: Include directories necessary to use FFMPEG. > * `FFMPEG_LIBRARIES`: Libraries necessary to use FFMPEG.
