2022-09-05qcam: viewfinder_gl: Fix maybe-uninitialized warningsMarco Felsch
Commit 251f0534b74b ("qcam: viewfinder_gl: Take color space into account for YUV rendering") introduced maybe-uninitialized warnings with gcc 11 and 12 when compiling with -O3. Both compilers warn that ../../src/qcam/viewfinder_gl.cpp: In member function ‘void ViewFinderGL::selectColorSpace(const libcamera::ColorSpace&)’: ../../src/qcam/viewfinder_gl.cpp:392:21: error: ‘offset’ may be used uninitialized in this function [-Werror=maybe-uninitialized] 391 | fragmentShaderDefines_.append(QString("#define YUV2RGB_Y_OFFSET %1") | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 392 | .arg(offset, 0, 'f', 1)); | ~~~~^~~~~~~~~~~~~~~~~~~ Additionally, gcc 12 warns that ../../src/qcam/viewfinder_gl.cpp: In member function ‘void ViewFinderGL::selectColorSpace(const libcamera::ColorSpace&)’: ../../src/qcam/viewfinder_gl.cpp:379:36: error: ‘yuv2rgb’ may be used uninitialized [-Werror=maybe-uninitialized] 379 | yuv2rgb[i] *= 255.0 / 219.0; ../../src/qcam/viewfinder_gl.cpp:330:31: note: ‘yuv2rgb’ declared here 330 | std::array<double, 9> yuv2rgb; | While this should never happen here, the compiler isn't necessarily wrong, as C++17 allows initializing a scoped enum from an integer using direct-list-initialization, even if the integer value doesn't match any of the enumerators for the scoped enum ([1]). Whether this is valid or borderline paranoia from gcc may be debatable, but in any case it can't be classified as blatantly wrong. Fix the warnings by adding default cases to the switch statements in ViewFinderGL::selectColorSpace(). Which case is selected as the default doesn't matter, as this is not meant to happen.

The ycbcrEncodingToV4l2 map is missing the YCbCrEncoding::None encoding, which results in a failure of V4L2Device::fromColorSpace() to convert color spaces from libcamera to V4L2 for RGB formats. Fix it by adding the missing encoding. As V4L2 has no such encoding, use V4L2_YCBCR_ENC_DEFAULT as the value doesn't matter.

2022-09-05qcam: Queue requests only through MainWindow::queueRequest()Utkarsh Tiwari
Currently to request a frame, we operate the camera directly. This approach is also scattered in two places, MainWindow::startCapture() and MainWindow::queueRequest(). This makes it difficult to account for requests. Centralize all the queuing to a single function queueRequest() Rename the current queueRequest() to renderComplete(). This makes more sense as this slot is triggered when the render is complete and we want to queue another request.

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.

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.

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.

2022-08-25libcamera: ipu3: Use std::max() instead of expandTo() to get the max resolutionHan-Lin Chen via libcamera-devel
Using Size::expandTo() to find the max resolution might generate a non-existent resolution. For example, when application request streams for 1920x1080 and 1600x1200, the max resolution will be wrongly 1920x1200 and fails the configuration.
