Patch 5/5 is the real deal.\n\nThis is an RFC since I still have a few more \\todos to address\nin 5/5. One in particular (which is also a source of crash)\nis marked with [BLOCKER] in 5/5.\n\nTesting:\npost-processor-jpeg runs in a separate thread and saves an image\non shutter-click. Streaming of image data continues as usual.\n\nHowever, on next shutter-click(i.e. trying to click yet-another-image)\nthe post-processor-worker thread fails to start, aborting the camera\nservice. This is [BLOCKER] I am currently resolving on my end.\n\nUmang Jain (5):\n android: post_processor: Inherit from libcamera::Object\n android: camera_stream: Pass FrameBuffer pointer instead of reference\n android: post_processor: Notify post processing completion status\n android: camera_stream: Notify process() status with a Signal\n android: Run post processing in a separate thread\n\n src/android/camera_device.cpp | 94 +++++++++++++++++++++---\n src/android/camera_device.h | 21 +++++-\n src/android/camera_stream.cpp | 54 ++++++++++++--\n src/android/camera_stream.h | 56 +++++++++++++-\n src/android/jpeg/encoder.h | 2 +-\n src/android/jpeg/encoder_libjpeg.cpp | 4 +-\n src/android/jpeg/encoder_libjpeg.h | 2 +-\n src/android/jpeg/post_processor_jpeg.cpp | 13 +++-\n src/android/jpeg/post_processor_jpeg.h | 4 +-\n src/android/jpeg/thumbnailer.cpp | 4 +-\n src/android/jpeg/thumbnailer.h | 2 +-\n src/android/post_processor.h | 13 +++-\n src/android/yuv/post_processor_yuv.cpp | 22 +++---\n src/android/yuv/post_processor_yuv.h | 4 +-\n 14 files changed, 248 insertions(+), 47 deletions(-)"}
