I've addressed all of Laurent's\nand David's comments from version 2. Additionally, some of the major changes in\nthis version include:\n\n- Adding a hints flag to StreamConfiguration. This allows us to remove the\n\"num_output0_buffers\" configuration option. This also required changes to the\nconfig validation, and buffer count calculations.\n- Reorder some of the commits to make more logical sense.\n- Switch to using *.yaml for the config files. Note that the format is still\nJSON based to be consistent with our tuning file.\n- Remove default.json. If no config file is provdied in the env variable, we\nsimply use const defaults that match default.json from v2.\n- We no longer need rpi_apps.yaml. This will be handled by the application\nsetting up the appropriate hint flag.\n\nThanks,\nNaush\n\nNaushir Patuck (13):\n libcamera: stream: Add stream hints to StreamConfiguration\n libcamera: pipeline: Add a platform configuration file helper\n pipeline: raspberrypi: Add a pipeline config structure\n pipeline: raspberrypi: Reorder startup drop frame initialisation\n pipeline: raspberrypi: Handle MandatoryRequestBuffer hints for Unicam\n Image\n libcamera: pipeline: build: Add pipeline_data_dir variable\n pipeline: raspberrypi: Read config parameters from a file\n pipeline: raspberrypi: Disable StreamOn for ISP Output0/1 when\n dropping frames\n pipeline: raspberrypi: Handle MandatoryRequestBuffer hints for ISP\n Output0\n pipeline: raspberrypi: Validate MandatoryRequestBuffer in\n queueRequestDevice()\n pipeline: raspberrypi: Add a parameter to disable startup drop frames\n pipeline: raspberrypi: Allow pipeline handler to always use the newest\n frame\n pipeline: raspberrypi: Add minimal memory usage config file\n\n include/libcamera/internal/pipeline_handler.h | 3 +\n include/libcamera/stream.h | 8 +\n src/libcamera/pipeline/meson.build | 3 +\n .../pipeline/raspberrypi/data/example.yaml | 29 ++\n .../pipeline/raspberrypi/data/meson.build | 9 +\n .../raspberrypi/data/minimal_mem.yaml | 29 ++\n .../pipeline/raspberrypi/meson.build | 2 +\n .../pipeline/raspberrypi/raspberrypi.cpp | 252 +++++++++++++++---\n src/libcamera/pipeline_handler.cpp | 60 +++++\n src/libcamera/stream.cpp | 24 ++\n 10 files changed, 384 insertions(+), 35 deletions(-)\n create mode 100644 src/libcamera/pipeline/raspberrypi/data/example.yaml\n create mode 100644 src/libcamera/pipeline/raspberrypi/data/meson.build\n create mode 100644 src/libcamera/pipeline/raspberrypi/data/minimal_mem.yaml"}
