      @SGaist ok thanks, i found all -dev packages for all the errors exept ffmpeg and dbus-linked.
      ./configure output is now:

      Note: Also available for Linux: linux-clang linux-icc
      
      Note: Dropped compiler flags '-pthread' when detecting library 'glib'.
      
      Note: Disabling X11 Accessibility Bridge: D-Bus or AT-SPI is missing.
      
      Note: Dropped compiler flags '-pthread' when detecting library 'gstreamer'.
      
      Note: Dropped compiler flags '-pthread' when detecting library 'gstreamer_app'.
      
      ERROR: Feature 'dbus-linked' was enabled, but the pre-condition 'features.dbus && libs.dbus' failed.
      
      ERROR: Feature 'system-ffmpeg' was enabled, but the pre-condition 'libs.ffmpeg && features.system-opus && features.system-webp' failed.
      
      Check config.log for details.
      

      Do i actually need ffmpeg for qtMultimedia? Since it is a videoplayer i guess yes. I think i have to install this from source to and that could be a real pain..

        You can install libavcodec-dev and friends for ffmpeg inclusion.

        As for dbus, the dbus dev package.

          @Xenoshell Why do you want to install ffmpeg from source? Install libavcodec-dev package from your Linux distribution.

            @SGaist i installed your suggested packages and now output is:

            @Jsulm i dont want to install ffmpeg from source. I just installed already the package and the error still occurs and i just googled the problem and the solution was to install from source

              Check the logs for the related errors. You can also use the -v option to get a more verbose output of the configuration process.

                  Install the libavformat and libavutil dev packages. Same goes for opus.

                        Just to let you know: I am the person who tried to help with your original "why I am unable to use the camera without freezing?" question!

                        I see this thread is getting long, I do hope my advice to sort out your multimedia installation fully is worth it for all this compiling etc. you're doing, and not a red-herring...!!

                          Don't build the tests nor the example, especially since your are cross-compiling. There's no use for that and you'll waste space, time and electricity for nothing.

                              @Xenoshell As you can see from what you posted those errors are coming from examples. As @SGaist suggested there is no need to build examples and tests (so, no these errors are not important). Use -skip to not to build examples and tests.

                                @jsulm yeah, since make is now finished its a little bit too late to skip the examples. But its good to know that those errors dont matter

                                        @Xenoshell Do you mean there is no libQt5Multimedia.* in lib directory and no header files?

                                          @jsulm nope in the lib folder there is only just everything else. Here is my command i used ./configure -opengl desktop -gui -widgets -gstreamer -pulseaudio -alsa -ffmpeg -dbus-linked, Do i maybe have to also add -multimedia?? I dont think there even is that command, but what do i have to do to install QtMultimedia
