The\nfailure or success is checked via the value returned by\nCameraStream::process().\n\nNow that the post-processor notifies about the post-processing\ncompletion operation and sets the ProcessStatus on the\nCamera3RequestDescriptor passed to it, we can drop the return value of\nCameraStream::process() in favour of reading the process status set on\nthe descriptor in the PostProcessor::processComplete's slot.\n\nSigned-off-by: Umang Jain \n---\n src/android/camera_device.cpp | 26 +++++++++++++-----------\n src/android/camera_stream.cpp | 12 +++++------\n
