2021-08-10libcamera: Give MappedFrameBuffer its own implementationKieran Bingham
The MappedFrameBuffer is a convenience feature which sits on top of the FrameBuffer and facilitates mapping it to CPU accessible memory with mmap. This implementation is internal and currently sits in the same internal files as the internal FrameBuffer, thus exposing those internals to users of the MappedFramebuffer implementation. Move the MappedFrameBuffer and MappedBuffer implementation to its own implementation files, and fix the sources throughout to use that accordingly.

2021-06-25libcamera/base: Move extended base functionalityKieran Bingham
Move the functionality for the following components to the new base support library: - BoundMethod - EventDispatcher - EventDispatcherPoll - Log - Message - Object - Signal - Semaphore - Thread - Timer While it would be preferable to see these split to move one component per commit, these components are all interdependent upon each other, which leaves us with one big change performing the move for all of them.

2021-01-27android: jpeg: Configure thumbnailer based on request metadataPaul Elder
Configure the thumbnailer based on the thumbnail parameters given by the android request metadata. Only the thumbnail encoder needs to be configured, and since it is only used at post-processing time, move the configuration out of the post-processor constructor and into the processing step. Also set the following android result metadata tags: - ANDROID_JPEG_THUMBNAIL_SIZE - ANDROID_JPEG_THUMBNAIL_QUALITY Signed-off-by: Paul Elder <paul.elder@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
