    "content": "Hi,\n\nQuite a few changes in version 3 of this series! 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"
