meta-qt5 not executing animated image (gif) file

yuva

Hi All,

I have build a Yocto Image (dunfell version 3.1.9) and trying to run the image on the raspberry pi model B. The sample Qt Gui which I build using Qt Kit 5.14.0 on my windows 10 machine contains some Sequential animation, Parallel Animation and AnimatedImage works fine without any issue.
But on the Raspberry Pi, I don't see the AnimatedImage getting executed.
I am not familiar with the required plugins required to run the AnimatedImage.
I have used the below RDEPENDS on my recipes,

SUMMARY = "Minimal set of Qt packages needed for QML apps"

inherit packagegroup

RDEPENDS_${PN} = " \
    fontconfig \
    ttf-bitstream-vera \
    qtbase \
    qtbase-plugins \
    qtdeclarative \
    qtdeclarative-qmlplugins \
    qtquickcontrols2 \
    qtgraphicaleffects \
    qtimageformats \
    qtmultimedia \
"

Could someone help me if I need to add any additional packages?
My CMakeLists.txt

    Item {
        id: mainWindow

        height: 480
        anchors.horizontalCenter: parent.horizontalCenter
        anchors.verticalCenter: parent.verticalCenter

        Rectangle {
            id:splashScrn
            width: parent.width; height: parent.height
            color: "#000000"
            anchors.horizontalCenter: parent.horizontalCenter
            anchors.verticalCenter: parent.verticalCenter

            AnimatedImage { id: animation; anchors.horizontalCenter: parent.horizontalCenter; anchors.verticalCenter: parent.verticalCenter; source: "qrc:/images/loading.gif";}
        }
   }
}

The below gif image is NOT displayed on the raspberry pi.

-Thanks in advance.

Hi and welcome to devnet,

You should check the imageformats folder to see which plugins have been built.

You can also print a least of the supported image formats using QImageReader::supportedImageFormats.

@SGaist said in meta-qt5 not executing animated image (gif) file:

imageformats folder

I could only see libqicns.so, libqjpeg.so, libqtga.so, libqtiff.so, libqwbmp.so, libqwebp.so files inside /usr/lib/plugins/imageformats folder.

Is there any libraries missing for AnimatedImage/gif file handling? If so how do I include to my recipes.

SGaist

There's likely libgif missing.

@SGaist I couldn't find libgif.so file anywhere. Can you help me to build/install those packages?
As a workaround, I converted the .gif file to .webp format as libqwebq.so plugin was available, but after first execution, the application started to flicker when running on the raspberry pi.

I am using eglfs, should I need to change to weston-wayland display compositor?

SGaist

Can you pass the -qt-gif parameter to your recipe when building Qt ?

@SGaist said in meta-qt5 not executing animated image (gif) file:

-qt-gif

bitbake sampleqtgui-image -qt-gif
Usage: bitbake [options] [recipename/target recipe:do_task ...]

    Executes the specified task (default is 'build') for a given set of target recipes (.bb files).
    It is assumed there is a conf/bblayers.conf available in cwd or in BBPATH which
    will provide the layer, BBFILES and other configuration information.

bitbake: error: no such option: -t

Should I need to modify the recipes for accepting '-qt-gif' parameter??

SGaist

That parameter should be added to the Qt recipe.
