2022-12-09py: Support controls that use an array of RectanglesDavid Plowman
The Python bindings will now accept, or return, a list or tuple of libcamera.Rectangle objects for such controls. This had previously been omitted, but now we have, for example, the AfWindows control which requires this feature.

2022-08-25libcamera: color_space: Rename Jpeg to SyccLaurent Pinchart
The JPEG color space is badly name, as the JPEG specification (ITU-T T.81) doesn't define any particular color space: The interchange format does not specify a complete coded image representation. Application-dependent information, e.g. colour space, is outside the scope of this Specification. The JFIF specification (ITU-T T.871) is clearer as it requires ITU-R BT.601 YCbCr encoding and a full quantization range: The interpretations of Y, CB, and CR are derived from the E'Y, E'Cb, and E'Cr signals defined in the 625-line specification of Rec. ITU-R BT.601, but these signals are normalized so as to permit the usage of the full range of 256 levels of the 8-bit binary encoding of the Y component. It however doesn't specify color primaries or a transfer function explicitly. It only mentions the latter when describing the conversion from YCbCr to RGB: The inverse relationship for computing full scale 8-bit per colour channel gamma pre-corrected RGB values (following Rec. ITU-R BT.601 gamma pre-correction and colour primary specifications) from YCbCr colours (with 256 levels per component) can be computed as follows: [...] Given that ITU-R BT.601-5 (1995) didn't specify color primaries or a transfer function, and that the later ITU-R BT.601-7 (2011) version specifies color primaries for the 625-line variant that do not match sRGB, the JPEG color space in libcamera is badly named. This is confirmed by ITU-T T.871: As this Recommendation | International Standard is based on the prior informally-circulated JFIF version 1.02 specification that was produced in 1992, which referenced Rec. ITU-R BT.601 (formerly CCIR 601), it references that specification for definition of the E'Y, E'Cb, and E'Cr signals that correspond to the YCBCR values specified herein. However, since the development of the prior JFIF version 1.02 specification, additional industry specifications have been developed, Rec. ITU-R BT.601 has been updated, and common industry practice has emerged which often follows the sYCC specification in IEC 61966-2-1/Amd.1. The difference between the use of the colour interpretation specification in this Recommendation | International Standard and that of the sYCC specification may be considered negligible in practice. Rename the color space to sYCC, as its definition matches the sYCC standard, and indicate that it is typically used to encode JPEG images.

2022-06-04py: Merge read_event() and get_ready_requests()Tomi Valkeinen
We always call CameraManager.read_event() and CameraManager.get_ready_requests(), so to simplify the use merge the read_event() into the get_ready_requests(). This has the side effect that get_ready_requests() will now block if there is no event ready. If we ever need to call get_ready_requests() in a polling manner we will need a new function which behaves differently. However, afaics the only sensible way to manage the event loop is to use select/poll on the eventfd and then call get_ready_requests() once, which is the use case what the current merged function supports.

We create symlinks from the Python bindings build dir to the source dir so that 1) the build dir can be used to use the bindings, and 2) to allow modifications of the source .py files to be used right away without rebuilding. The symlinks were recently fixed and changed to use absolute paths. However, absolute paths ruin one main use case I have: using the bindings from the build dir via nfs from an ARM device. So move back to relative paths, but accomplish this with the --relative parameter for ln, instead of guessing the right relative path as was done before the above-mentioned fix.
