How to mute QML camera

[Taz742]

when I capture images, camera has sound and I want to mute it

Hi,

Isn't that a setting of your device ?

[Taz742]

@SGaist
Yes but I want to write code

[SGaist]

Well, that's the thing: OS level settings like that can usually not be modified by code.

You should check your target platform documentation for such use case.

I have also one problem, I use timer and every 4 seconds it takes photos, but sometimes my screen becomes black, is this qml bug?

[SGaist]

I don't know. You don't give any details that may help answer your question like:

• Target platform where that happens
• Qt version
• Code snippet that you use for that
• etc.

@SGaist
platform is Lenovo A319 android version 4.4.2
QT 5.8.0

Timer
{
id: tim
interval: 2000; running: true; repeat: true
onTriggered:
{
if (camera.lockStatus === Camera.Locked)
{
camera.imageCapture.capture()
camera.unlock()
}
else
camera.searchAndLock()
}
}

In your code you are taking photos at 2 seconds interval not 4. Are you sure your device can sustain that speed ? You also have to take into account that each image is saved on your device.

@SGaist
no no, after 2 seconds "if" operator is false and it doesn't take photos

[SGaist]

Good point, I've somehow missed the unlock call.

Did you check the state of your phone storage ?

@SGaist
when photo is taken, I use it for something and remove from default location

[SGaist]

Did you check the time that it takes to do that ?
