There's not\nreally any change in functionality here though I have in the main\ntaken people's suggestions on board. Just a few notes on some of that:\n\n* I've de-inlined some code. I've left operator!= inline, though, as\n there seemed to be some precedent for that.\n\n* I haven't replaced that vector by a map because it would require us\n to have an ordering for ColorSpaces (operator< etc.). I seem to\n recall inventing arbitrary orderings in the past, I guess it depends\n which approach we dislike least... thoughts?\n\n* The ColorSpace now gets updated after a tryFormat. Thanks for\n pointing that out.\n\nOne final question in relation to this: I was hoping not to list every\nlast colour space variant that exists in V4L2, mostly because many of\nthem seem quite esoteric to me. Or would we rather simply mirror\neverything in V4L2 straight away?\n\nThanks!\n\nDavid\n\nDavid Plowman (3):\n libcamera: Add ColorSpace class\n libcamera: Support passing ColorSpaces to V4L2 drivers\n libcamera: pipeline: raspberrypi: Support colour spaces\n\n include/libcamera/color_space.h | 83 +++++++\n include/libcamera/internal/v4l2_videodevice.h | 2 +\n include/libcamera/meson.build | 1 +\n include/libcamera/stream.h | 3 +\n src/libcamera/color_space.cpp | 207 ++++++++++++++++++\n src/libcamera/meson.build | 1 +\n .../pipeline/raspberrypi/raspberrypi.cpp | 84 +++++++\n src/libcamera/v4l2_videodevice.cpp | 119 ++++++++++\n 8 files changed, 500 insertions(+)\n create mode 100644 include/libcamera/color_space.h\n create mode 100644 src/libcamera/color_space.cpp" }
