[libcamera-devel] [RFC PATCH 0/6] Support stream mapping in Android HAL adaptation layer

[Hirokazu Honda]

This patch series implements a stream mapping in Android HAL
adaptaion layer. The stream mapping here means to map camera
streams that can be produced by a native camera to camera streams
requested by Android HAL client w/o post processing. This is
helpful for the libcamera Android HAL implementation to produce
camera streams that a camera device doesn't support and output
multiple streams.

Hirokazu Honda (6):
  libcamera: camera: Add tryValidate() to CameraConfiguration
  libcamera: ipu3: Implement tryValidate() in IPU3CameraConfiguration
  android: camera_stream: Pass post processor in configure()
  android: camera_device: Implement toString() in Camera3StreamConfig
  android: camera_device: Introduce PostProcessorType
  android: camera_device: Support stream mapping
