Libcamera: Is it next universal AOSP Camera HAL?

The talk will highlight how libcamera’s modular architecture can significantly accelerate camera bring-up and product development on Android platforms. I will present a real-world case study that outlines the steps taken to support buffer allocation in Gralloc and the challenges faced when dealing with image format and stride mismatches while bring up

I would be talking about :

libcamera - deep dive

• What is open-source libcamera?

• libcamera and AOSP general architecture

• Building libcamera with AOSP

• libcamera pipeline and essential properties

• libcamera HAL and the importance of buffer management (Gralloc module)

  Debugging techniques:

• Dumping buffers at different levels

• Recreating images using tools like YUV Viewer

• Analyzing Camera App dumpsys output to detect stride mismatches

  Current stage of adoption for libcamera.

This session will be valuable for developers working on AOSP-based camera stacks, especially those targeting custom hardware or aiming to leverage modern, community-driven alternatives to traditional proprietary HALs.
