QML invalid property objectName (M16) for videooutput

[dquy05]

Hi everybody !

I got this error in qml,

VideoOutput {
            id: videoOutput
            objectName: "show"   // error invalid property objectName (M16) 
            source: camera
            anchors.fill: parent
        }

VideoOutput {
            id: videoOutput
            objectName: "show"   // error invalid property objectName (M16) 
            source: camera
            anchors.fill: parent
        }

I moved the imports to the top one by one but still got the error,
I use Android 11, Qt5.15, NDK21,
is it because I use Qt5.15?
I really need to fix this error, can anyone help me?

Thanks!

objectName: "show" // error invalid property objectName (M16)

Isn't it obvious? The error message is telling you exactly what is wrong: VideoOutput does not have a property named "objectName" so you can't assign a value to it.
