Patches 7~8 move formats out of V4L2CameraProxy, and clean\nup some of its code. Patch 10 forces pipeline handlers to use\nacquireMediaDevice so that media devices can automatically be mapped to\ndevnums for the v4l2 compatibility layer to intercept, and patch 11\nmakes the raspberrypi pipeline handler conform to this. Patches 12~13\nfilter out unsupported formats at configuration generation time, to\nprevent them from being selected, in the pipeline handlers that hadn't\nalready done so. Patches 14~19 move filling in the stide and frameSize\nparameters from camera configuration time to configuration validation\ntime.\n\nChanges in v4:\n- upgraded documentation of format info definitions\n- added overloaded PixelFormatInfo::stride() that takes alignment\n- added optional parameter to PixelFormatInfo::frameSize that takes\n array of strides\n- raspberrypi: fill in default format and frame size\n- simple: fix stride and frameSize for converter (compared to v3)\n- use tryFormat to get stride and frameSize for all pipelines except for\n ipu3\n\nPaul Elder (21):\n libcamera: formats: Add NV24 and NV42, and reorder NV formats\n libcamera: formats: Add fields to info to ease calculating stride\n libcamera: StreamConfiguration: Add frameSize field\n libcamera: V4L2VideoDevice: Add tryFormat\n libcamera: formats: PixelFormatInfo: Add v4l2 lookup function\n libcamera: PixelFormatInfo: Add functions stride and frameSize\n v4l2: v4l2_camera_proxy: Get stride and frameSize from stream config\n v4l2: v4l2_camera_proxy: Use stream config in tryFormat\n libcamera: pipeline: raspberrypi: Simplify format fetching\n libcamera: pipeline: raspberrypi: Acquire media devices with\n acquireMediaDevice\n libcamera: pipeline_handler: Fatal if registering camera without media\n devices\n libcamera: pipeline: raspberrypi: Filter out unsupported formats\n libcamera: pipeline: uvcvideo: Filter out unsupported formats\n libcamera: ipu3: Fill stride and frameSize at config validation\n libcamera: raspberrypi: Fill stride and frameSize at config validation\n libcamera: rkisp1: Fill stride and frameSize at config validation\n libcamera: simple: Fill stride and frameSize at config validation\n libcamera: uvcvideo: Fill stride and frameSize at config validation\n libcamera: vimc: Fill stride and frameSize at config validation\n libcamera: StreamConfiguration: Update stride documentation\n v4l2: v4l2_camera: Fix stream selection for buffer operations\n\n include/libcamera/internal/formats.h | 17 ++\n include/libcamera/internal/v4l2_videodevice.h | 7 +-\n include/libcamera/stream.h | 1 +\n src/libcamera/formats.cpp | 282 +++++++++++++++++-\n src/libcamera/pipeline/ipu3/ipu3.cpp | 23 +-\n .../pipeline/raspberrypi/raspberrypi.cpp | 81 ++---\n src/libcamera/pipeline/rkisp1/rkisp1.cpp | 20 +-\n src/libcamera/pipeline/simple/converter.cpp | 19 ++\n src/libcamera/pipeline/simple/converter.h | 4 +\n src/libcamera/pipeline/simple/simple.cpp | 27 +-\n src/libcamera/pipeline/uvcvideo/uvcvideo.cpp | 36 ++-\n src/libcamera/pipeline/vimc/vimc.cpp | 23 +-\n src/libcamera/pipeline_handler.cpp | 4 +\n src/libcamera/stream.cpp | 22 +-\n src/libcamera/v4l2_videodevice.cpp | 50 +++-\n src/v4l2/v4l2_camera.cpp | 26 +-\n src/v4l2/v4l2_camera.h | 3 +\n src/v4l2/v4l2_camera_proxy.cpp | 207 +++----------\n src/v4l2/v4l2_camera_proxy.h | 8 -\n 19 files changed, 578 insertions(+), 282 deletions(-)" }
