      @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.

          @Joe-von-Habsburg I think you did not set pkg configure path. If you do not know how to set it, find the pkg files in gstreamer installation and add all the libs inside to your project.

              @Joe-von-Habsburg pkg config path is under gstreamer lib dir.
              For example in Linux
              /opt/thirdParties/gstreamer/lib/pkgconfig
              Maybe it is different in Windows
              and pkg-config.exe has to be in system path of Windows.

                  add C:/gstreamer/1.0/msvc_x86_64/bin to PATH on Windows. This enables you to run pkg-config.exe and use pkg-config. Nice that gstreamer includes it for you.
                  go to C:/gstreamer/1.0/msvc_x86_64/lib to find dir pkgconfig. Add C:/gstreamer/1.0/msvc_x86_64/lib/pkgconfig to PKG_CONFIG_PATH

                  Do not forget to add gstreamer plugin path as well in your env. Otherwise, you can not run your gstreamer app.

                      If it does not exist, you are unable to use it. I can check it out later for you in my home Windows.

                                @JoeCFD said in GStreamer with QT6:

                                ":" is missing in the picture.

                                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

                                    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.
