Brax3 Dual Camera capability

BraX3 iodéOS

@plamen I’m trying to develop a Dual Camera app mostly for combining the Omnivision 50MP back camera with the Galaxy Core 5MP front camera.

I can’t get any concurrent cameras with CameraX or logical cameras with Camera2.

Mediatek specifies that the ISP can process 2×16MP camera streams and I know that Xiaomi Redmi 15C 5G uses the Mediatek Dimensity 6300 and combines the 2 back cameras (Omnivision + Samsung) for its AI camera feature.

Also the Mediatek binary files for Brax3 imply the existence of logical cameras through their filenames.

Now I’m studying the latest camera HAL based on AIDL.

The question is whether the lack of dual camera capability is a building configuration issue of either LineageOS or iodéOS.

Is there some build configuration file concerning the HAL interfaces for the camera?

Pixels support dual camera, even a stock Pixel 2 XL I have access to.

Do we have any example from degoogled Pixels that can combine the 2 cameras at the same time?

it seems that the AI features are implemented through the binaries so the dual camera configuration may not be available directly to the developer, after researching the HAL I’m going down to the direct binary blob calls through the native C/C++ code though I don’t expect any result
