    Hi
    When I build a release version the background animations don't play (all of type mp4).
    They do play from within the Visual Studio debugger.

    I have tried the steps here and it still does not work when executed from the Deployment folder.
    All DLLs, QML folders and Plugin folders were copied over and still no luck.
    https://wiki.qt.io/Deploy_an_Application_on_Windows

    I use the windeployqt technique to build.
    I am building on VisualStudio 2017 and QT 5.12.2 (msvc2017)

    I have tried multiple versions of windows (xp, 7, 10) on multiple machines.
    Is it something I am forgetting to do when choosing to build a release version from within VS?
    Any ideas?

      1. Play your video in the Visual Studio debugger.
      2. While it is playing, use ListDLLs to print the list of all loaded DLLs.
      3. (Try to) play your video in your release build.
      4. While it is running, use ListDLLs to print the list of all loaded DLLs.

      What do you notice?

        can you post the command you used ?

          Thanks for the replies.
          So the command I used was -
          cd C:\Qt\5.12.2\msvc2017\bin
          windeployqt C:\Users\me\Documents\incommandCopy\Win32\Release

          The ListDLLs displays a lot more entries for when the video plays compared to when it doesn't.
          Not sure where to start ->

            there you have it, you did not give the tool the path to (your) QMl files -> QML imports are not present

            --qmldir

            If your application uses Qt Quick, run:
              windeployqt --qmldir <path-to-app-qml-files> <path-to-app-binary>

              @J-Hilk Ah I see, thanks. I thought that was definitely the solution
              However videos still not playing for the release build.
              I ran the following command

              windeployqt.exe --qmldir C:\Users\me\Documents\incommand2017\InCommand\Resources C:\Users\me\Documents\incommand2017\Win32\Release

              I even then pointed to the entire QML folder, still no luck
              windeployqt.exe --qmldir C:\Qt\5.12.2\msvc2017\qml C:\Users\me\Documents\incommand2017\Win32\Release

              I'm probably doing something silly here

                See https://wiki.qt.io/Deploy_an_Application_on_Windows for manual deployment. Note that you also need to deploy the qmldir files for the Qt Quick plugins.

                  See https://wiki.qt.io/Deploy_an_Application_on_Windows for manual deployment. Note that you also need to deploy the qmldir files for the Qt Quick plugins.

                  @JKSH Thanks for the help
                  I ended up finding every file missing (there was 110) and moving them all to -:

                  C:\Users\me\Documents\incommand2017\Win32\Release
                  And still no mp4 playback when it runs as a release version rather than debug

                    That's too many! You don't need to copy the DLLs from C:\Windows, for example.

                    And still no mp4 playback when it runs as a release version rather than debug

                    1. Did you deploy the qmldir files?
                    2. What does ListDLLs show after you've moved the DLLs?

                      OK thanks, just to be safe I took everything.

                        Don't do that. It can cause crashes if you move system DLLs to a different PC with a slightly different version of Windows.

                        I'm still seeing C:\Windows DLLs that shouldn't be in your deployment folder, like C:\Users\USER\Documents\incommand2017\Win32\Release\WINMM.dll.

                        Please clean up your build folder (delete everything), build your app from scratch, then deploy ONLY Qt files.

                        BTW, I'm not seeing plugins\mediaservice\dsengine.dll get loaded. That's the one needed to play videos. One thing to try:

                        • Put plugins\mediaservice\dsengine.dll in your release folder but delete plugins\mediaservice\wmfengine.dll
                        • Put plugins\mediaservice\wmfengine.dll in your release folder but delete plugins\mediaservice\dsengine.dll

                          @JKSH Tried that, still no luck.
                          Clean build.
                          I just have a multimedia folder no plugins folder, don't know if that makes a difference -> \mediaservice\dsengine.dll

                          I notice during the Listdll for when it works in debug it loads lots of codec files which are not present during the Release run, would this matter?

                            @celica Hi Guys
                            Still having issues, do you think the lack of codec files deployed during the release build has an effect?

                              Yes, it kind of matters because those codecs are used to play videos. However, you should not deploy those codec DLLs directly. They should be installed on your PC via the codec installer.

                              Qt loads the codecs via a mediaservice plugin.

                                @JKSH Thanks, I tried that. You're right dsengine.dll does not get loaded.
                                In fact nothing does from the mediaservice folder.
                                Both from the output window within visual studio after a release build and from the Listdll result when it is running.
                                Is there any way of forcing it to load this file?

                                I tried removing the files you mention to no avail.
                                All the codecs were installed via the codec installer.

                                  Ah, this is an important clue.

                                  That means it's not a deployment issue. Rather, there's something broken in the Release build. Don't bother trying to deploy until the Release build works fine in Visual Studio.

                                  Try setting the environment variable QT_DEBUG_PLUGINS to 1 before running the app from Visual Studio OR from the command line. What messages do you see when it tries to load plugins?

                                      I'm not sure how to set that variable as I run the app from within Visual Studio 2017

                                      You could temporarily set it in your PC's global environment. Just remember to un-set it after.

                                        I set it within my code using this: qputenv("QT_DEBUG_PLUGINS", QByteArray("1"));

                                          Yes, it's relevant -- it shows that your app has not loaded your mediaservice plugins.

                                          Your QFactoryLoader lines are:

                                          1. You have plugin folders in 2 places. How did this happen? (The folders should only be in 1 place, by the way)
                                            • C:/Users/USER/Documents/incommandnew/platforms/
                                            • C:/Users/USER/Documents/incommandnew/Win32/Release/platforms/
                                          2. What's in C:/Users/USER/Documents/incommandnew/Win32/Release/mediaservice?
