Hi everybody !

I got this error in qml,

Qt Code:
  1. VideoOutput {
  2. id: videoOutput
  3. objectName: "show" // error invalid property objectName (M16)
  4. source: camera
  5. anchors.fill: parent
  6. }
To copy to clipboard, switch view to plain text mode

.qml

Qt Code:
  1. import QtQml 2.12
  2. import QtQml.Models 2.3
  3. import QtQuick 2.12
  4. import QtQuick.Window 2.12
  5. import QtQuick.Controls 2.5
  6. import QtQuick.Layouts 1.0
  7. import QtMultimedia 5.12
  8. import QtQuick.Controls.Material 2.0
To copy to clipboard, switch view to plain text mode 

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!
