@Negar_mg If you check https://code.qt.io/cgit/qt/qtmultimedia.git/tree/examples/multimediawidgets/camera/camera.cpp?h=5.15 you will see

ui->captureWidget->setTabEnabled(1, (m_camera->isCaptureModeSupported(QCamera::CaptureVideo)));

So, it sets the "Video" tab to enabled if m_camera->isCaptureModeSupported(QCamera::CaptureVideo) returns true. It looks like for your camera it returns false. I don't know what you can do to change this.
Does your camera support video recording?

@jsulm
I tested this camera with opencv and it had no problem,
On the other hand, I tested this program on a laptop, with a webcam, and it was the same.
Is it possible that the problem is using Windows?

[jsulm]

@Negar_mg It should work.
What Qt version and compiler do you use?

[Negar_mg]

@jsulm
qt creator 4.15.0
kit=qt 5.12.11 MSVC2015 64bit

[jsulm]

@Negar_mg Can you try with more recent version (5.15.2)?

[Negar_mg]

@jsulm
I'm trying now.

My program only has these kits. Can it be added to the new kit?

Can it be added to the new kit?

Yes, install current Qt version for your compiler, then you should get a new Kit automatically.
If you used Qt Online Installer to install Qt, then you can use Qt Maintenance Tool (you can find it in the root folder of your Qt set-up, c:\qt).

Thank you for your help
I used Qt_5_15_2-Debug, but the part related to video recording is still inactive.
I encountered this error while using this kit:
Unsupported media type: "{32595559-0000-0010-8000-00AA00389B71}"
