2021-03-03android: Move buffer mapping to CameraStreamJacopo Mondi
The destination buffer for the post-processing component is currently first mapped in the CameraDevice class and then passed to CameraStream which simply calls the post-processor interface. Move the mapping to CameraStream::process() to tie the buffer mapping to the lifetime of the CameraBuffer instance.

2021-02-02android: post_processor: Change the type destination in process()Hirokazu Honda
The type of the destination buffer in PostProcessor::process() is libcamera::Span. libcamera::Span is used for one dimension buffer (e.g. blob buffer). The destination can be multiple dimensions buffer (e.g. yuv frame). Therefore, this changes the type of the destination buffer to MappedFrameBuffer.

2020-10-21android: camera_stream: Make some member variables constantHirokazu Honda
CameraStream initializes several member variables in the initializer list. Some of them are unchanged after. This makes them constant. Especially, doing to |cameraDevice_| represents CameraStream doesn't have the ownership of it.

2020-10-21android: Modify PostProcessor interfaceHirokazu Honda
In PostProcessor::process(), the |source| argument doesn't have to be a pointer. This replaces its type, const pointer, with const reference as the latter is preferred to the former. libcamera::Span is cheap to construct/copy/move. We should deal with the type as pass-by-value parameter. Therefore this also drops the const reference in the |destination| argument.

2020-10-07android: camera_stream: Create buffer poolJacopo Mondi
Add a FrameBufferAllocator class member to the CameraStream class. The allocator is constructed for CameraStream instances that needs internal allocation and automatically deleted. Allocate FrameBuffers using the allocator_ class member in the CameraStream class at CameraStream::configure() time and add two methods to the CameraStream class to get and put FrameBuffer pointers from the pool of allocated buffers. As buffer allocation can take place only after the Camera has been configured, move the CameraStream configuration loop in the CameraDevice class after camera_->configure() call. The newly created pool will be used to provide buffers to CameraStream that need to provide memory to libcamera where to deliver frames.

2020-10-07android: camera_stream: Fetch format and size from configurationJacopo Mondi
Fetch the format and size of the libcamera::StreamConfiguration associated with a CameraStream by accessing the configuration by index. This removes the need to store the libcamera stream format and sizes as class members and avoid duplicating information that might get out of sync. It also allows to remove the StreamConfiguration from the constructor parameters list, as it can be identified by its index. While at it, re-order the constructor parameters order.
