    it can be there. Try to reinstall it in different ways.

      @Joe-von-Habsburg I edited my post. You need to figure out how to set pkg path on Windows.

      On linux:
      export PKG_CONFIG_PATH=/opt/thirdParties/gstreamer/lib/pkgconfig:$PKG_CONFIG_PATH

      it is easier to use pkg config to add packages into a project because all dependencies are taken care of. But you can add all libs manually as well.

      I download files with msys :

      pacman -S mingw-w64-x86_64-gstreamer mingw-w64-x86_64-gst-plugins-base \
            mingw-w64-x86_64-gst-plugins-good mingw-w64-x86_64-gst-plugins-bad \
            mingw-w64-x86_64-gst-plugins-ugly mingw-w64-x86_64-gst-libav \
            mingw-w64-x86_64-gst-rtsp-server
      

      and I copy the pkgconfig to lib like that

      image.png

      and gsreamer-1.0.pc and gsteamer-video-1.0.pc exist

      image.png

      cmake like that :

      PKG_CONFIG_PATH=C:/gstreamer/1.0/msvc_x86_64/lib/pkgconfig:$PKG_CONFIG_PATH
      find_package( PkgConfig REQUIRED )
      pkg_search_module( GSTREAMER REQUIRED IMPORTED_TARGET gstreamer-1.0)
      pkg_search_module( GSTREAMER-VIDEO REQUIRED IMPORTED_TARGET gstreamer-video-1.0)
      

      but its not work

          I forgot about it and added it. the code shows it as added. but nothing happened. i keep getting the error. i'm sure the solution is very simple in linux. i wish it could be the same in windows.

            hey, the problem is that you need to write it like this:
            set(PKG_CONFIG_PATH=C:/gstreamer/1.0/msvc_x86_64/lib/pkgconfig:$PKG_CONFIG_PATH)
            this way it should work, I had the same problem last week

              Could not work on me :/

              Where do you install gstreamer and where do you install pkgconfig folder in lib ?

                open one of the pc files and check if the prefix is correct.

                The installed pkg config path is basically fixed under lib. Do not try to change it.

                                Run the pkg-config command on the command line and you will see I would guess.
