All the context information\nis carried via Camera3RequestDescriptor.\n\n1/7 and 2/7 are improved !nullptr checks that were spotted in previous\nreview.\n\n3/7 under takes a refactor of splitting Camera3RequestDescriptor::Status\nto denote only status(success/error). The \"pending\" status is de-coupled\ninto a separate variable now.\n\n4/7 Consolidates all the information we need to run the post-processor\ninto Camera3RequestDescriptor::Stream. Now use this structure only and\nupdate signature of PostProcessor::process() vfunc.\n\n5/7 Introduces a post-processing request tracking std::map and a signal\nof completion. The tracking map will help us to know if there are\nmultiple post-processing streams per descriptor (i.e. capture request).\nIf so, we need to wait, track until all streams are processed. Only\nthen we can mark descriptor for completion.\n\n6/7 is a small inherent patch based on 5/7's change \n\n7/7 is where a post-processor's worker class is introduced. At this\npoint, the post-processor will run asynchronously.\n\nUmang Jain (7):\n android: camera_stream: Replace post-processor nullptr check\n android: post_processor_jpeg: Replace encoder_ nullptr check\n android: camera_device: Refactor descriptor status and\n sendCaptureResults()\n android: post_processor: Consolidate contextual information\n android: Track and notify post processing of streams\n android: post_processor: Drop return value for process()\n android: post_processor: Make post processing async\n\n src/android/camera_device.cpp | 144 ++++++++++++++---------\n src/android/camera_device.h | 5 +\n src/android/camera_request.cpp | 3 +-\n src/android/camera_request.h | 18 ++-\n src/android/camera_stream.cpp | 133 +++++++++++++++++++--\n src/android/camera_stream.h | 41 ++++++-\n src/android/jpeg/post_processor_jpeg.cpp | 20 ++--\n src/android/jpeg/post_processor_jpeg.h | 4 +-\n src/android/post_processor.h | 16 ++-\n src/android/yuv/post_processor_yuv.cpp | 21 ++--\n src/android/yuv/post_processor_yuv.h | 4 +-\n 11 files changed, 305 insertions(+), 104 deletions(-)" }
