Patch 2/6 then moves format conversion from\nV4L2VideoDevice to V4L2PixelFormat, and patch 3/6 replaces the big\nswitch-case's with std::map.\n\nPatch 4/6 further rework V4L2PixelFormat by splitting the\nPixelFormatInfo class out and exposing it as an internal API. Patch 5/6\nadds Bayer formats support to both PixelFormatInfo and V4L2PixelFormat.\nPath 6/6 finally adds additional data to PixelFormatInfo.\n\nLaurent Pinchart (6):\n libcamera: v4l2_pixelformat: Move V4L2PixelFormat to a new file\n libcamera: v4l2_pixelformat: Move DRM/V4L2 format conversion\n libcamera: v4l2_pixelformat: Use maps to convert between DRM and V4L2\n libcamera: formats: Expose PixelFormatInfo as an internal API\n libcamera: formats: Add support for 8-, 10- and 12-bit Bayer formats\n libcamera: formats: Add additional data to PixelFormatInfo\n\n src/libcamera/formats.cpp | 335 +++++++++++++++++++\n src/libcamera/include/formats.h | 24 ++\n src/libcamera/include/meson.build | 1 +\n src/libcamera/include/v4l2_pixelformat.h | 49 +++\n src/libcamera/include/v4l2_videodevice.h | 27 +-\n src/libcamera/meson.build | 1 +\n src/libcamera/pipeline/uvcvideo/uvcvideo.cpp | 2 +-\n src/libcamera/v4l2_pixelformat.cpp | 209 ++++++++++++\n src/libcamera/v4l2_videodevice.cpp | 224 +------------\n test/libtest/buffer_source.cpp | 4 +-\n 10 files changed, 625 insertions(+), 251 deletions(-)\n create mode 100644 src/libcamera/include/v4l2_pixelformat.h\n create mode 100644 src/libcamera/v4l2_pixelformat.cpp"}
