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:opencv-4.10.0.zip and ffmpeg-master-latest-win64-gpl-shared.zip
Create a build directory C:/opencv/build and a cmake dirctory C:/fmpeg-master-latest-win64-gpl-shared/cmakeffmpeg-config.cmake ) mentioned in C:/fmpeg-master-latest-win64-gpl-shared/cmakeConfigure 。after a while, use Add Entry add FFMPEG_DIR and OPENCV_FFMPEG_USE_FIND_PACKAGE ,which as follows:
List item click Configure again ,after a while,Cmake output show as follows:
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:
Do you receive any warnings etc. in the window at the bottom before the configuration output?

in the output of my ffmpeg :#define LIBAVCODEC_VERSION_MINOR 26 #define LIBAVCODEC_VERSION_MICRO 100.26.100)#define LIBAVFORMAT_VERSION_MINOR 9 #define LIBAVFORMAT_VERSION_MICRO 100.9.100)– avutil: YES (59.47.101) #define LIBSWSCALE_VERSION_MINOR 12 #define LIBSWSCALE_VERSION_MICRO 100.12.100)
the avutil
but it is different with yours– avutil: YES (57.17.100)
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 below.
ffmpeg-config.cmake
#[==[
Provides the following variables:
* `FFMPEG_INCLUDE_DIRS`: Include directories necessary to use FFMPEG.
* `FFMPEG_LIBRARIES`: Libraries necessary to use FFMPEG. Note that this only
includes libraries for the components requested.
* `FFMPEG_VERSION`: The version of FFMPEG found.
The following components are supported:
* `avcodec`
* `avdevice`
* `avfilter`
* `avformat`
* `avresample`
* `avutil`
* `swresample`
* `swscale`
For each component, the following are provided:
* `FFMPEG_<component>_FOUND`: Libraries for the component.
* `FFMPEG_<component>_INCLUDE_DIRS`: Include directories for
the component.
* `FFMPEG_<component>_LIBRARIES`: Libraries for the component.
* `FFMPEG::<component>`: A target to use with `target_link_libraries`.
Note that only components requested with `COMPONENTS` or `OPTIONAL_COMPONENTS`
are guaranteed to set these variables or provide targets.
