          @sgaist I don't know, could you tell me how to check it out.
          should I download gstreamer from https://gstreamer.freedesktop.org/src/qt-gstreamer/?

            Use your distribution package manager for that or rather the one from your target device if you are cross-compiling.

              It just show me about the gst-

              root@imx6qsabresd:~# gst-
              gst-device-monitor-1.0  gst-launch-1.0          gst-typefind-1.0
              gst-discoverer-1.0      gst-play-1.0            
              gst-inspect-1.0         gst-stats-1.0           
              

              also I find gstreamer-1.0 in /usr/share/

                    Sorry, I'm new to the embedded, I'm not sure what the distribution means. Is the core board on the device? It's NXP ARM 7 cortex-A9. Or the system version? It's Arm-linux kernel 4.1.15.

                        Linux distribution refers to Ubuntu or CentOS? If yes, I just know I'm using Ubuntu 12.04 on VMWare on PC. Is NXP also a Linux distribution?
                        I got this message by uname -a :

                        root@imx6qsabresd:~# uname -a

                        Is this what you need?

                          No, NXP is not a Linux distribution, it's a semiconductor manufacturer.

                          Do you have somewhere in the documentation provided some information about the software stack running on your device ?

                            As far as I know, we can get the Linux distribution from /etc/issue.net or /proc/version. But the content is

                            cat /etc/issue.net 
                            Freescale i.MX Release Distro 4.1.15-2.1.0 %h
                            
                            cat /proc/version
                            Linux version 4.1.15 (vmuser@Linux-host) (gcc version 5.3.0 (GCC) ) #9 SMP PREEMPT Fri Aug 23 10:07:29 CST 2019
                            

                            I think they had been changed by Freescale, so I can't know the original distribution. Or maybe I can get it from customer service or their forum.

                              @sgaist Now I want to cross-compile again, and I got a new ubuntu to do it following Building Qt 5 from Git. When configuring, it couldn't checking for GStreamer: GStreamer support cannot be enabled due to functionality tests!. What should I do?

                              Maybe I know what Linux distribution the Freescale use, it's Yocto!

                                You need the GStreamer development packages installed.

                                  @sgaist I use QT_DEBUG_PLUGINS to see the output:

                                  Also I ready to compile qt-gstreamer, cus I have installed GStreamer on Ubuntu bysudo apt-get install, but it doesn't work:

                                  , and I add all these path into $PATH, it also doesn't work
                                  (Project WARNING: pkg-config disabled, can't check package existence Project ERROR: gstreamer-1.0 development package not found)
                                  .

                                  Or should I find the code to cross-compiler the GStreamer and export PKG_CONFIG_PATH for configure?

                                  Thank you so much for your support~

                                    You need the GStreamer development packages installed.

                                      QtGStreamer is not an official Qt module and unrelated to QtMultimedia.

                                      You should rather use GStreamer 1.0.

                                      Are you sure these are installed and not just downloaded ?

                                        @sgaist Ok, a bit messy now, let's tidy up first.
                                        I only use QMediaPlayer to play a music.
                                        On Ubuntu(VMWare), it's working without any error message.
                                        But on Arm-Linux(yocto, provided by NXP, maybe), it doesn't work with error message:
                                        defaultServiceProvider::requestService(): no service found for - "org.qt-project.qt.mediaplayer"
                                        If Qt Multimedia doesn't relate to Qt GStreamer but the basic GStreamer, how can I check whether the device support Qt Multimedia or not, cus I can play mp3 by mplayer, I can find the basic GStreamer(gstreamer 1.0 )on the device.
                                        Or do you have other suggestion to play music with adjusting volume and schedule, cus QSound can not adjust these attributes; QAudioOutput must set any other attributes(sample rate and channel); QSoundEffect can not adjust schedule.
                                        BTW, could QMediaPlayer play the wav file?
                                        Also, I ran the example /usr/share/qt5/examples/multimedia/imxplayer/imxplayer,it 's a Qt5 demo media palyer integrated with freescale Gstreamer 1.0 framework for X11 graphics.

                                        root@imx6qsabresd:~# /usr/share/qt5/examples/multimedia/imxplayer/imxplayer 
                                        ** Message: GStreamer version 1.8.1
                                        display(/dev/fb0) resolution is (1280x800).

                                        It can find the basic GStreamer.

                                          If it's yocto based, then there's likely packages that you can enable in the recipe.
