Add support for color space to the uvcvideo pipeline handler.

2022-09-01libcamera: color_space: Move color space adjustment to ColorSpace classUmang Jain
The CameraConfiguration::validateColorSpaces() function performs color space validation on a camera configuration, by validating the color space of each stream individually, and optionally ensuring that all streams share the same color space. The individual validation is very basic, limited to ensuring that raw formats use a raw color space. Color spaces are more constrained than that: - The Y'CbCr encoding and quantization range for RGB formats must be YcbcrEncoding::None and Range::Full respectively. - The Y'CbCr encoding for YUV formats must not be YcbcrEncoding::None. Instead of open-coding these constraints in the validateColorSpaces() function, create a new ColorSpace::adjust() function to centralize color space validation and adjustment, and use it in validateColorSpaces().

2022-09-01libcamera: colorspace: Rectify the ColorSpace::Srgb presetUmang Jain
Rectify the ColorSpace::Srgb to denote that it does not use any Y'Cbcr encoding and uses full range. The kernel on the other hand, recommends to use Rec601 as the encoding for V4L2_COLORSPACE_SRGB. It is not very explicit but it can be inferred that the kernel assumes V4L2_COLORSPACE_SRGB is a YUV-encoded one. However, when the data is in RGB, no encoding is required (and this is denoted by YcbcrEncoding::None in libcamera). Hence, to be clear on the libcamera colorspace API, rectify the ColorSpace::Srgb preset to use YcbcrEncoding::None and full range.

V4L2 has no "none" YCbCr encoding, and thus reports an encoding for all formats, including RGB and raw formats. This causes the libcamera ColorSpace to report incorrect encodings for non-YUV formats. Fix it by overriding the encoding reported by the kernel to YCbCrEncoding::None for non-YUV pixel formats and media bus formats. Similarly, override the quantization range of non-YUV formats to full range, as limited range isn't used for RGB and raw formats.

If a pointer-to-member is passed to the Signal::connect() function with arguments that don't match the Signal type, the pointer-to-member version of connect() will not match during template argument resolution, but the functor version will.

Doxyfile.in was generated using `doxygen -g` with Doxygen v1.8.14. This has produced a file with all options supported by Doxygen at the time, and a handful of them have then been modified to support libcamera's needs, with most options retaining their default. Some of the default options have been deprecated in newer Doxygen releases, which led to warnings when generating the documentation. The usual process to fix this is to update the configuration file with `doxygen -u`. This creates a big diff due to the large number of changes to default options, which isn't quite nice. Instead, let's just drop all the default options and the comments, to produce a small and more readable Doxyfile.in.

Implement color space support in the rkisp1 pipeline handler, in the configuration generation, configuration validation and camera configuration. As all the processing related to the color space is performed in the part of the pipeline shared by all streams, a single color space must cover all stream configurations. This is enforced manually when generating the configuration, and with the validateColorSpaces() helper when validating it. Only the Y'CbCr encoding and quantization range are currently taken into account, and they are programmed through the V4L2 color space API. The primary colors chromaticities and the transfer function need to be configured in the ISP parameters buffer, and thus conveyed to the IPA, but the rkisp1 driver does not currently support tone mapping, so this will be done later.

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.

2022-08-20libcamera: v4l2: Set colorspace flagsUmang Jain
The colorspace fields are read-only from an application point of view, both on video devices and on subdevs, unless the V4L2_PIX_FMT_FLAG_SET_CSC or V4L2_MBUS_FRAMEFMT_SET_CSC flags (respectively) are set when calling the S_FMT ioctl. Set the flags accordingly within the V4L2SubDevice and V4L2Device when a colorspace is being set by the application.

2022-08-19ipa: rkisp1: Add manual color gainsPaul Elder
Add support for manually controlling the color gains on the rkisp1 IPA. To that end, add and plumb the AwbEnable and ColourGains controls. As per-frame controls aren't supported yet in the rkisp1 IPA, simply apply and perform checks on the controls immediately.

2022-08-19py: Create PyCameraManagerTomi Valkeinen
Wrap the CameraManager with a PyCameraManager class and move the related code inside the new class. This helps understanding the life times of the used-to-be global variables, gets rid of static handleRequestCompleted function, and allows us to simplify the binding code as the more complex pieces are inside the class. There should be no user visible functional changes.
