One\nexample of this could be making use of the Arducam 4 camera multiplexor\n[0] connected to the Debix Model A which we have used for testing this.\n\n[0] https://www.arducam.com/product/multi-camera-v2-1-adapter-raspberry-pi/\n\nThis series convers only the RkISP1 for now, but I could anticipate an\nadditional series will also convert the Simple Pipeline handler to make\nuse of this new helper class. The Mali-C55 and other pipeline handlers\nwhich antipate user configurable input paths would also be able to make\nuse of this implementation.\n\nKieran Bingham (4):\n libcamera: media_device: Add helper to return matching entities\n libcamera: pipeline: rkisp1: Fix typo in todo task\n libcamera: internal: Add MediaPipeline helper\n libcamera: pipeline: rkisp1: Convert to use MediaPipeline\n\n include/libcamera/internal/media_device.h | 2 +\n include/libcamera/internal/media_pipeline.h | 59 ++++\n include/libcamera/internal/meson.build | 1 +\n src/libcamera/media_device.cpp | 25 +-\n src/libcamera/media_pipeline.cpp | 307 ++++++++++++++++++++\n src/libcamera/meson.build | 1 +\n src/libcamera/pipeline/rkisp1/rkisp1.cpp | 88 +++---\n 7 files changed, 427 insertions(+), 56 deletions(-)\n create mode 100644 include/libcamera/internal/media_pipeline.h\n create mode 100644 src/libcamera/media_pipeline.cpp"}
