The numerical fourcc codes used for PixelFormat\nare the DRM/KMS defined DRM_FORMAT_* fourcc codes.\n\nHelpers for conversion to/from PixelFormat and V4L2_PIX_FMT_* are provided in\nthe V4L2 video device and used in all pipeline handlers. Finally the test\napplication and QCam are ported to use te DRM/KMS defined pixel codes.\n\nThanks Laurent for having looked at the series and fixed the nasty DRM/V4L2 RBG\nformat conversion issues.\n\nThanks\n j\n\nJacopo Mondi (9):\n include: linux: Update headers to Linux v5.2\n include: linux: Import DRM/KMS headers from Linux v5.2\n include: drm_fourcc: Add Motion-JPEG fourcc code\n libcamera: Define PixelFormat type\n libcamera: stream: Use the newly defined PixelFormat\n libcamera: v4l2_videodevice: Add PixelFormat conversion\n libcamera: pipeline: Use PixelFormat for application formats\n qcam: Convert to use DRM formats\n test: camera: buffer_import: Use DRM/KMS format\n\nLaurent Pinchart (1):\n libcamera: formats: Write libcamera in lowercase\n\n include/libcamera/meson.build | 1 +\n include/libcamera/pixelformats.h | 18 +\n include/libcamera/stream.h | 13 +-\n include/linux/drm.h | 1042 ++++++++++++++++++++++\n include/linux/drm_fourcc.h | 765 ++++++++++++++++\n include/linux/drm_mode.h | 1032 +++++++++++++++++++++\n include/linux/media-bus-format.h | 4 +-\n include/linux/media.h | 27 +-\n include/linux/v4l2-controls.h | 29 +\n include/linux/videodev2.h | 31 +-\n src/libcamera/formats.cpp | 2 +-\n src/libcamera/include/formats.h | 2 +-\n src/libcamera/include/v4l2_videodevice.h | 5 +\n src/libcamera/meson.build | 1 +\n src/libcamera/pipeline/ipu3/ipu3.cpp | 7 +-\n src/libcamera/pipeline/rkisp1/rkisp1.cpp | 25 +-\n src/libcamera/pipeline/uvcvideo.cpp | 4 +-\n src/libcamera/pipeline/vimc.cpp | 15 +-\n src/libcamera/pixelformats.cpp | 28 +\n src/libcamera/stream.cpp | 17 +-\n src/libcamera/v4l2_videodevice.cpp | 141 +++\n src/qcam/format_converter.cpp | 30 +-\n test/camera/buffer_import.cpp | 4 +-\n 23 files changed, 3170 insertions(+), 73 deletions(-)\n create mode 100644 include/libcamera/pixelformats.h\n create mode 100644 include/linux/drm.h\n create mode 100644 include/linux/drm_fourcc.h\n create mode 100644 include/linux/drm_mode.h\n create mode 100644 src/libcamera/pixelformats.cpp\n\n--\n2.23.0" }
