    Yes, I could play sound on this server machine. I have installed Winamp and tried to play my audio file, It worked.

    I would like my application support on Windows server also.

      @William.Tran Did you try what I suggested before (QT_DEBUG_PLUGINS)?

          @William.Tran You don't do it in your application - it is an environment variable. Either set it in the terminal where you start your app or add it in "Projects/Run/Run Environment" in QtCreator.

              @William.Tran Just execute you app and check its output (in QtCreator "Application Output" tab).

                I received the log informations related to media server :

                "The plugin 'C:/Qt/Qt5.7.0/5.7/msvc2013_64/plugins/mediaservice/qtmedia_audioengined.dll' uses incompatible Qt library. (Cannot mix debug and release libraries.)"
                not a plugin

                As i can see now, it looks like QT could not load the plugin. Do you have any idea?

                  @William.Tran said in QMediaPlayer without output:

                  Cannot mix debug and release libraries.

                  This says what the problem is: you're mixing debug and release libraries.
                  How did you deploy your app?
                  This plug-in is missing: Cannot load library C:\Qt\Qt5.7.0\5.7\msvc2013_64\plugins\mediaservice*dsengine.dll*: The specified module could not be found."

                  Take a look at http://doc.qt.io/qt-5/windows-deployment.html

                    I may have problem with deployment process. But this is the log information when i run my project on QT directly. so i think it should work right?

                    I have checked the DLL in C:\Qt\Qt5.7.0\5.7\msvc2013_64\plugins\mediaservice they are there. But i don't know why they could not be loaded. Is it QT Creator problem ?

                    I did clean project and run again but still get the same problem. Do you have any suggestion?

                        @William.Tran Are you trying to execute debug or release build?
                        Did you try to delete the build directory, execute qmake and then build again?

                          Besides the log warnings, are you sure the needed backend is in place ?

                          You could run dxdia and see if all is as expected.

                                  As far as i know, winamp can play mp3 by itself and can work with no directX installed. ?
                                  If true it dont help test.

                                      Just to be clear
                                      DirectX(DirectShow) needs to be installed.
