2021-01-27android: jpeg: Set thumbnail and JPEG quality based on requestPaul Elder

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.
