RealSense BGRA Buffer Doesn't Work with ZXing about librealsense HOT 5 CLOSED

Hi @ffreality There is a mention of the development of the RealSense UE5 plugin and ZXing at the January 2024 Unreal forum link below. Is this posting by you, please?

If the librealsense2 SDK is built from source code on Windows with CMake with the build flag -DFORCE_RSUSB_BACKEND=TRUE then the SDK's backend should be based on a WinUSB rewrite of the UVC protocol (the SDK's backend on Linux) instead of the default backend on Windows, which is Microsoft Media Foundation. This may make setup of the UE5 plugin more complicated though and I cannot guarantee that it will make a difference to whether ZXing will be able to decode the feed directly.

Yes, I was the one who answering it. (I am Eray Ozer and one of co-founders of our startup)
Couple months ago before the question asked, I could read A4 sized QR codes from correct angle but right now I can't read with direct buffer. On the other hand, if I read buffer from texture, decoding won't problem.

Thank you very much for your suggestion. I want to update RealSense library as well. I can also try it.

@MartyG-RealSense I updated the library.

Good thing:
I downloaded released WIN10 SDK and everything works correctly including ZXing.

Bad Thing:
CMake description said that -DFORCE_RSUSB_BACKEND=TRUE was mandatory for Win builds and also It asked LibUsb library (include and lib.) I built and pointed them. Both RealSense and LibUsb gave no error but right now everything is broken.
I can't even list my attached D455
(If I use my custom built)

These are my CMake Config

I do not see the flag CMAKE_BUILD_TYPE in the lists. This would typically be used when building from source with CMake in Linux and is given the status Release. If the SDK is not set to build in Release mode then by default it builds in Debug mode for SDK development instead.

I set it as Release on Visual Studio 2022.
Anyway I close this issue because build problem is another issue's subject and actually I can download it from GitHub. So, it won't matter.
