The PostProcessor interface can be configured via\nconfigure() and the actual processing can be initiated using process().\n\nThe post-processing layer can be extended to have multiple post\nprocessors for various stream configurations. As of now, we only have\none post processor (JPEG), hence the subsequent commit will port its\nfunction to this interface.\n\nSigned-off-by: Umang Jain \nReviewed-by: Kieran Bingham \nReviewed-by: Laurent Pinchart \n---\n src/android/post_processor.h | 28 ++++++++++++++++++++++++++++\n 1 file changed, 28 insertions(+)\n create mode 100644 src/android/post_processor.h","diff":"diff --git a/src/android/post_processor.h b/src/android/post_processor.h\nnew file mode 100644\nindex 0000000..a891c43\n--- /dev/null\n+++ b/src/android/post_processor.h\n@@ -0,0 +1,28 @@\n+/* SPDX-License-Identifier: LGPL-2.1-or-later */\n+/*\n+ * Copyright (C) 2020, Google Inc.\n+ *\n+ * post_processor.h - CameraStream Post Processing Interface\n+ */\n+#ifndef __ANDROID_POST_PROCESSOR_H__\n+#define __ANDROID_POST_PROCESSOR_H__\n+\n+#include \n+#include \n+#include \n+\n+class CameraMetadata;\n+\n+class PostProcessor\n+{\n+public:\n+\tvirtual ~PostProcessor() {}\n+\n+\tvirtual int configure(const libcamera::StreamConfiguration &inCfg,\n+\t\t\t const libcamera::StreamConfiguration &outCfg) = 0;\n+\tvirtual int process(const libcamera::FrameBuffer *source,\n+\t\t\t const libcamera::Span &destination,\n+\t\t\t CameraMetadata *metadata) = 0;\n+};\n+\n+#endif /* __ANDROID_POST_PROCESSOR_H__ */\n","prefixes":["libcamera-devel","v2","1/2"]}
