Patch 2/4 then moves format conversion from\nV4L2VideoDevice to V4L2PixelFormat, and patch 3/4 replaces the big\nswitch-case's with std::map. Patch 4/4 finally adds support for\nMIPI-packed 10-bit Bayer formats.\n\nLaurent Pinchart (4):\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: v4l2_pixelformat: Add support for 10-bit Bayer formats\n\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 | 292 +++++++++++++++++++\n src/libcamera/v4l2_videodevice.cpp | 224 +-------------\n test/libtest/buffer_source.cpp | 4 +-\n 8 files changed, 349 insertions(+), 251 deletions(-)\n create mode 100644 src/libcamera/include/v4l2_pixelformat.h\n create mode 100644 src/libcamera/v4l2_pixelformat.cpp" }
