Any problems with portrait photography when the device is in the landscape?

Question

I am making a rather special camera application for a device that will always physically be stored in landscape orientation. Part of the specification is that it should be able to preview and photograph in portrait orientation - see Image below.

I am having problems excluding "setParameters failed" from the runtime (in response to a call to camera.setParameters() ), and I just wanted to check here if there was any fundamental problem with which, in your opinion, I could collide. For example, it is possible that the light sensors on the back of the camera are located in a rectangle, and physically this cannot be achieved — or perhaps some other inevitable problem. (By the way, I was informed that light sensors should be squared, so this problem will not occur, but my sources may be wrong). Maybe it depends on the equipment?

EDIT: FYI my crash log below:

Answer 1

I made a small camera testing app a while ago. There was no problem to show a camera preview in portrait mode, while the device was in landscape orientation. It was difficult to rotate the camera image at a right angle (because this angle of rotation depends on the device / camera). However, the problem was that the perspective did not match then: the object seemed thicker or stretched. But to find out that the recalculation algorithm should not take a lot of time in Stackoverflow.

I just wanted to check here if there was any fundamental problem that you think I could be against.

[...] and physically this cannot be achieved - or perhaps some other inevitable problem.

Answer: this is a doable task. Your exclusion probably has a completely different reason.
