[libcamera-devel] [RFC PATCH v3 0/4] pipeline: isp: The software ISP module

[Siyuan Fan]

From: Fan Siyuan <siyuan.fan at foxmail.com>

Changes in v3:
- Using std::queue replaces std::vector for rawBufferQueue_ and rgbBufferQueue_ in 1/4
- Add validate() in pipeline handler in 1/4, for matching the ISP output format
- Add pixelFormatConfiguration() and getOutputPixelFormat() in 2/4
- Drop compress_10bit_to_8bit(), using compressAndTransformFormat() in 2/4

For next version, class ISPCPU will split the parameter computation/calibration and pixel
processing. For pre-calibrated parameters, it may be a good choice to match different
parameters to different devices.

Fan Siyuan (4):
  pipeline: isp: The software ISP-based pipeline handler
  libcamera: swisp: The software ISP class
  libcamera: framebuffer: Add the friend class ISPCPU
  pipeline: isp: All meson configure files
