This is\nuseful on platforms that don't have a converter, but also on platforms\nwhere the SoC camera pipeline has limitations on resolution and/or\nbandwidth.\n\nPatches 1/5 and 2/5 are small drive-by improvements, patches 3/5 and 4/5\nprepare for sensor scaling support with some code refactoring, and patch\n5/5 then performs the bulk of the work, with an explanation of the\nheuristics used to configure scaling.\n\nLaurent Pinchart (5):\n libcamera: pipeline: simple: Improve debug message on config failure\n libcamera: pipeline: simple: Document the pipeline traversal algorithm\n libcamera: pipeline: simple: Factor out format test to separate\n function\n libcamera: pipeline: simple: Store sensor resolution in configuration\n libcamera: pipeline: simple: Support scaling on the sensor\n\n src/libcamera/pipeline/simple/simple.cpp | 262 ++++++++++++++++-------\n 1 file changed, 182 insertions(+), 80 deletions(-)\n\n\nbase-commit: 8a845ab078c3fe12ac4edd16c8cbac5b7ec03b98" }
