It's not a big change, but things are very\nslightly different there now.\n\nThis has shown up one little niggle, which is that the V4L2 subdevice\nnow complains about retrieving an undefined colour space - from the\nmetadata pad! Currently I've left the warning in but added the pad\nnumber in the message. The metadata pad is easy to spot in practice\nbecause it always has a non-zero pad number. But is there a proper way\nto know this?\n\nThanks\n\nDavid\n\nDavid Plowman (7):\n libcamera: Add ColorSpace class\n libcamera: Add ColorSpace fields to StreamConfiguration\n libcamera: Convert between ColorSpace class and V4L2 formats\n libcamera: Support passing ColorSpaces to V4L2 video devices\n libcamera: Support passing ColorSpaces to V4L2 subdevices\n libcamera: Add validateColorSpaces to CameraConfiguration class\n libcamera: pipeline: raspberrypi: Support color spaces\n\n include/libcamera/camera.h | 2 +\n include/libcamera/color_space.h | 88 ++++++\n include/libcamera/internal/v4l2_device.h | 7 +\n include/libcamera/internal/v4l2_subdevice.h | 2 +\n include/libcamera/internal/v4l2_videodevice.h | 2 +\n include/libcamera/meson.build | 1 +\n include/libcamera/stream.h | 4 +\n src/libcamera/camera.cpp | 51 ++++\n src/libcamera/camera_sensor.cpp | 1 +\n src/libcamera/color_space.cpp | 257 ++++++++++++++++++\n src/libcamera/meson.build | 1 +\n .../pipeline/raspberrypi/raspberrypi.cpp | 42 +++\n src/libcamera/stream.cpp | 25 ++\n src/libcamera/v4l2_device.cpp | 171 ++++++++++++\n src/libcamera/v4l2_subdevice.cpp | 42 ++-\n src/libcamera/v4l2_videodevice.cpp | 67 ++++-\n 16 files changed, 758 insertions(+), 5 deletions(-)\n create mode 100644 include/libcamera/color_space.h\n create mode 100644 src/libcamera/color_space.cpp"}
