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/1317276\n\nThere are still some discussion of the new signal in the previous patch,\nwith Jacopo. I'll update the patch when we reach agreement.\n\nI understand that the last patch is a bit large, while I don't know how\nto split that furthermore. Let me know if there are some pieces that can\nbe standalone patches.\n\nBR,\nHarvey\n\n\nHan-Lin Chen (2):\n libcamera: Camera: Add signals for completion of metadata as a partial\n result\n android: Add JpegExifMetadata to store tags setting into Exif\n\nHarvey Yang (7):\n android: Move StreamBuffer out of Camera3RequestDescriptor\n android: Set StreamBuffer::srcBuffer in\n CameraDevice::processCaptureRequest\n android: Migrate StreamBuffer::internalBuffer to\n Camera3RequestDescriptor\n android: Add CameraDevice::sendCaptureResult()\n android: Cleanup CAMERA3_MSG_ERROR_REQUEST\n android: Remove Camera3RequestDescriptor::streamsProcessMutex_\n android: Support partial results\n\n include/libcamera/camera.h | 1 +\n include/libcamera/internal/pipeline_handler.h | 1 +\n include/libcamera/internal/request.h | 4 +\n include/libcamera/request.h | 1 +\n src/android/camera_capabilities.cpp | 11 +-\n src/android/camera_capabilities.h | 2 +\n src/android/camera_device.cpp | 926 ++++++++++++------\n src/android/camera_device.h | 46 +-\n src/android/camera_request.cpp | 94 +-\n src/android/camera_request.h | 96 +-\n src/android/camera_stream.cpp | 20 +-\n src/android/camera_stream.h | 10 +-\n src/android/jpeg/encoder.h | 2 +-\n src/android/jpeg/encoder_jea.cpp | 2 +-\n src/android/jpeg/encoder_jea.h | 2 +-\n src/android/jpeg/encoder_libjpeg.cpp | 2 +-\n src/android/jpeg/encoder_libjpeg.h | 2 +-\n src/android/jpeg/post_processor_jpeg.cpp | 16 +-\n src/android/jpeg/post_processor_jpeg.h | 2 +-\n src/android/post_processor.h | 4 +-\n src/android/yuv/post_processor_yuv.cpp | 2 +-\n src/android/yuv/post_processor_yuv.h | 2 +-\n src/libcamera/camera.cpp | 6 +\n src/libcamera/pipeline_handler.cpp | 41 +\n src/libcamera/request.cpp | 21 +\n 25 files changed, 908 insertions(+), 408 deletions(-)" }
