Splitting them into\ndifferent partial results should fit both MediaTek's and Intel's\nrequirements.\n\nThis patch passed gitlab pipeline:\nhttps://gitlab.freedesktop.org/chenghaoyang/libcamera/-/pipelines/1269599\n\nPatches in Android adapter that implement partial results will follow\nthis one.\n\nBR,\nHarvey\n\nHan-Lin Chen (1):\n libcamera: Camera: Add signals for completion of metadata as a partial\n result\n\n include/libcamera/camera.h | 1 +\n include/libcamera/internal/pipeline_handler.h | 1 +\n include/libcamera/request.h | 5 +++\n src/libcamera/camera.cpp | 6 +++\n src/libcamera/pipeline_handler.cpp | 37 +++++++++++++++++++\n src/libcamera/request.cpp | 20 ++++++++++\n 6 files changed, 70 insertions(+)"}
