    Did you re-run your configure from a clean state after syncing your RPi's sysroot ?

    @SGaist yes... I've reconfigured and also I've recompiled Qtbase and tried to compile with the last version .. same results...

    ~/raspi/qt5/bin/qmake -r GST_VERSION=1.0

      @SGaist Also when you said to run the config.. do you mean on the Qtbase? or on Qtmultimedia? - ./config on QtMultimedia is nor working - there is no config there... and if I run the config on Qtbase.. what is the scope for it? do I have to recompile QtBase? Anyway, I've recompiled QtBase.. same results with the new qmake...

        When running only qmake -r I'm getting this:

        Qt is now configured for building. Just run 'make'.
        Once everything is built, Qt is installed.
        You should NOT run 'make install'.
        Note that this build cannot be deployed to other machines or devices.
        
        Prior to reconfiguration, make sure you remove any leftovers from
        the previous build.

          From the looks of it, it seems OK.

            @SGaist yes I know it seems ok.. but it does not compile... that is the problem... also When I compile it without

            GST_VERSION=1.0
            

            is passing the alsa check - but with it no...
            also without it is giving

            cmake executable not found. Not running CMake unit tests
            

            which is strange again... Hmmm... what it can be??

              What if you disable ALSA support ?

              The cmake warning can be ignored, it just states that the related tests won't be run.

                @SGaist but I need Alsa support! I'm using ALSA with IQaudio Pi-DigiAMP+.
                What other option do you think is available?
                how to disable ALSA? and how to ignore the < Not running CMake unit tests > How to disable those tests anyway?

                  I don't remember the options when using qmake directly, however you can comment the alsa relate lines in qtmultimedia/src/plugins.pro.

                    @SGaist yep but what alternative do I have without ALSA? will PulseAudio work without ALSA? As far as I can see Qt is supporting only ALSA and PulseAudio and nothing else...

                    Qt Multimedia:
                      ALSA ................................... yes
                      GStreamer 1.0 .......................... yes
                      GStreamer 0.10 ......................... no
                      Video for Linux ........................ yes
                      OpenAL ................................. no
                      PulseAudio ............................. yes
                      Resource Policy (libresourceqt5) ....... no
                      Windows Audio Services ................. no
                      DirectShow ............................. no
                      Windows Media Foundation ............... no
                    

                    at least into my configuration

                      I meant that as a test to ensure that you could build the module. So then we can concentrate on why ALSA is not found properly at compile time.

                        I meant that as a test to ensure that you could build the module. So then we can concentrate on why ALSA is not found properly at compile time.

                        @SGaist after googling a lot .. my conclusion is that there is some sort of problem in QtMultimedia relating to gStreamer version - a fight between old one 0.1 and new one 1.0...

                        "No decoder available for type 'audio/mpeg, mpegversion=(int)1, mpegaudioversion=(int)1, layer=(int)3, rate=(int)44100, channels=(int)2, parsed=(boolean)true'."
                        

                        this appeared on my Pi as a program error...

                        by the way, I've also realised that compiling QtMultimedia just with

                        ~/raspi/qtmultimedia$ ~/raspi/qt5/bin/qmake -r
                        

                        is working but when I'm trying to specify the GST version with

                        GST_VERSION=1.0
                        

                        it can not find ALSA....
                        witch, to be honest, is strange for me... that means 2 things:

                        1. without gst version is compiling using gstreamer 0.1 witch acourding to this
                        Qt Multimedia:
                          ALSA ................................... yes
                          GStreamer 1.0 .......................... yes
                          GStreamer 0.10 ......................... no
                          Video for Linux ........................ yes
                          OpenAL ................................. no
                          PulseAudio ............................. yes
                          Resource Policy (libresourceqt5) ....... no
                          Windows Audio Services ................. no
                          DirectShow ............................. no
                          Windows Media Foundation ............... no
                        

                        is not even available - but I can see that the compile finish without any error

                        1. is using the new GStreamer 1.0 which is also found by the configure.. but.. why is finding ALSA now? Where is ALSA??

                        ..... Realy strange... at least for me...

                          You have both version of GStreamer installed on your sysroot ?

                            @SGaist As you can see form configure (I think that configure is looking into sysroot if I'm not wrong) It says only 1.0..

                              @SGaist
                              after a lot more digging here is what I've just found out

                              • delete the libraries containing the unwanted elements (like /usr/lib/arm-linux-gnueabihf/gstreamer-1.0/libgstomx.so)
                              • delete the cache ~/.cache/gstreamer-1.0/registry.arm.bin
                              • re-run the application

                              all are useless - at least in my case.

                              • adapt QtMultimedia source code, see and re-compile, cf. http://code.qt.io/cgit/qt/qtmultimedia.git/tree/src/plugins/gstreamer/mediaplayer/qgstreamerplayersession.cpp?id=eedba02427aa4750011f010319bf34959ecbd3e1&h=5.10.0#n168

                              and changed from "autoaudiosink" to "alsasink"
                              is giving this now:

                                  @SGaist this is when I try to crosscompile QtMultimedia after modifying that line there - when running

                                    Take a look at the tests to see what failed exactly.

                                          until I find a proper way of doing it for Raspberry Pi.. here you have a workaround this problem - delete the libgtsomx.so I had to delete also the libgstomx-rpi.so then delete the cache.
                                          but this is just a workaround and making it to work.. I do not know if that is the proper way of doing it...
