customized app is kill when changing image's property

[vuhailongkl97]

Issue description

currently when I change image source's properties as Rotation I got a warning like this

Do you want to change the source rotation?
Check that your apps work properly after. If they don't, restart the camera.

I would know events which raised for the event to my application ?

Could you give me some advice to handle the events (if have) to my app can work properly.

Hi @vuhailongkl97 , thanks for reaching out.

The normal use case for image rotation that I know of is to adapt the image output to how a camera is mounted. But after mounting the camera the position is fixed and the rotation don't change.

Most if not all applications and APIs should have been developed for a fix scene or image that's never rotated. If rotation setting is changed it would affect this basic precondition and I think that's what the warning is about.

For products with auto-rotation, the camera itself can adjust the image to how it's physically mounted.

@pataxis thank you. That means if users want the application to work after the changed rotation, they must restart the axis device, and on the software side, I can't fix that. Right?

I guess it depends on the application, some may not be affected, some may work after restarting the application and some need a restart of the device itself. It could also depend on which product and firmware version.
