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.

2020-10-28android: jpeg: encoder_libjpeg: Allow encoding raw frame bytesUmang Jain
Allow encoding frames which are directly handed over to the encoder via a span or vector i.e. a raw frame bytes. Introduce an overloaded EncoderLibJpeg::encode() with libcamera::Span source parameter to achieve this functionality. This makes the libjpeg-encoder a bit flexible for use case such as compressing a thumbnail generated for Exif.

2020-10-23android: jpeg: encoder: Use pass-by-value for Exif parameterUmang Jain
Following the reasoning of pass-by-value for libcamera::Span parameters from 90c193f2a700("android: Modify Encoder interface") i.e. they are easy to copy/move/construct, align the Exif parameter passing to the encoder interface in this consistent way.

2020-10-21android: Modify Encoder interfaceHirokazu Honda
In Encoder::encode(), 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.

2020-10-16android: jpeg: Port to PostProcessor interfaceUmang Jain
Port the CameraStream's JPEG-encoding bits to PostProcessorJpeg. This encapsulates the encoder and EXIF generation code into the PostProcessorJpeg layer and removes these specifics related to JPEG, from the CameraStream itself.

2020-09-10android: jpeg: Support an initial set of EXIF metadata tagsUmang Jain
Create a Exif object with various metadata tags set, just before the encoder starts to encode the frame. The object is passed directly as libcamera::Span<> to make sure EXIF tags can be set in a single place i.e. in CameraDevice and the encoder only has the job to write the data in the final output.
