QMovie, gif and QRC

quniq

Hello
I'm trying to deploy application for Windows. I am using a QMovie widget with gif loaded to play. The problem is, movie.isValid() says that it is not.
I can see, that my gif is listed in the qrc file, and all files listed are converted to qrc_ProgramName.cpp (with gif).
All pictures are included (and visible in program), so I think, that all files are attached to exe.

The problem is that QMovie doesn't play gif animation.
I've found, that it is neccesary to deploy application with qgif.dll file, but it still doesn't work...
Please, help me!

I am using 2 toolchains:
Qt 5.3.1 with mingw 4.82 x32
Qt 5.4.1 with mingw 4.91 x32

Hi and welcome to devnet,

How did you deploy your application ? Did you put everything in the correct location ?

Hello,
Maybe your missing ":/" or "qrc:/" in path to Your gif (or path to the gif inside resource is wrong)?

Thank you for reply.

My full qrc file (spaces are removed...):

<RCC>
<qresource prefix="/">
<file>langs/pl.qm</file>
<file>langs/hu.qm</file>
<file>icons/wait_animation.gif</file>
<file>langs/pl.ts</file>
<file>langs/hu.ts</file>
<file>icons/wait_animation_trans.gif</file>
<file>icons/Previous-icon.png</file>
<file>icons/Next-icon.png</file>
<file>icons/Symbols-Delete-icon.png</file>
</qresource>
</RCC>

All files are in folders as listed (in project). In deployed program those files do not need to be found in program folder.

Code fragment:

QMovie *movie = new QMovie(this);
movie->setFileName(":/icons/wait_animation_trans.gif");

How did I deploy? Simply built application in release, and copied it into separate folder with dll's:
icudt52.dll
icuin52.dll
icuuc52.dll
libgcc_s_dw2-1.dll
libstdc++-6.dll
libwinpthread-1.dll
qgif.dll
Qt5Core.dll
Qt5Gui.dll
Qt5Multimedia.dll
Qt5SerialPort.dll
Qt5Widgets.dll

Fragments of my *.pro file:

RESOURCES += ResidentsList.qrc
RC_FILE = ResidentsList.rc
TRANSLATIONS += langs/pl.ts
TRANSLATIONS += langs/hu.ts
QTPLUGIN += qgif

I don't have any more ideas...

qgif.dll needs to be in a subfolder. See http://wiki.qt.io/Deploy_an_Application_on_Windows

And that's the information I missed. I found that qgif should be in 'plugins' folder, but it seems to work in qt4 only. qfgif.dll has to be stored in 'imageformats' subfolder.
Thanks a lot!
