    Default Deploying Qt 5.0.2 Windows 7 MinGW VideoGraphicsItem .dll's

    So I successfully compiled the videographicsitem sample code in Qt 5.0.2 - Windows7 - MinGW as a release...
    It works just fine on the system that has Qt 5.0.2 installed on it. However, I packaged it with all the so called dependencies that the application requested. And then tried to run it on an OS without Qt 5.0.2 installed & it doesn't work.
    I remembered reading that certain plugins need to be in their own directory from the exe folder...
    so I added /imageformats and /mediaservices and then when that didn't work, I put ALL the plugin directories and dll's into the application folder. Still nothing... I went through and got the can't find .dll errors for each .dll (the hardway) after putting in.....

    these are the .dll's that are requested:

    icudt51.dll
    icuin51.dll
    icuuc.dll
    libgcc_s_dw2-1.dll
    libGLESv2.dll
    libpcre16-0.dll
    libpng15-15.dll
    libstdc++-6.dll
    libwinpthread-1.dll
    Qt5Core.dll
    Qt5Gui.dll
    Qt5Multimedia.dll
    Qt5MultimediaWidgets.dll
    Qt5Network.dll
    Qt5OpenGL.dll
    Qt5Widgets.dll

    and then I add the folders:

    /imageformats with all non-debug .dll's
    /mediaservice with all non-debug .dll's

    it is strange to me, because it feels like the compiled release version is somehow using the debug .dll's
    but that cannot be, as all requested .dll's were the non-debug versions. So I'm somehow missing a .dll
    or a video release application can't be built to be stand alone? Anybody have any idea why I can't get
    the application's release build to run with these .dll's present?

    ok I just put in everything and pulled things out and ran the application.

    Solution: (in addition to the above you must add)

    libEGL.dll

    and plugin directory

    /platforms with all non-debug .dll's
