2024-09-11qcam: viewfinder_gl: Render image centered in letterboxLaurent Pinchart
Mimic the letterbox behaviour of the Qt viewfinder by rendering the image centered. This is done by adding a projection matrix to the vertex shader to scale the rendered rectangle. Another option would have been to keep using glViewport() (which would have needed to be moved to paintGL(), as Qt resets the viewport to span the full widget before calling). Hidpi displays would then need special handling of the device pixel ratio, which is done automatically by Qt when it sets the default viewport. Using a projection matrix avoids this complication.

There's no need to call glClearColor() twice before drawing any GL content. Drop the first call. This doesn't introduce any functional change. While at it, pass floats instead of doubles to glClearColor(), as required by the function.

2024-09-11qcam: viewfinder_gl: Fix binding of vertex buffer and shader programLaurent Pinchart
Starting in Qt 6.7.0, vertex buffers and shader programs are unbound just before calling QOpenGLWidget::paintGL(). This breaks rendering in the GL viewfinder in two ways. First, we bind the vertex buffer only once at initialization time. There is therefore no vertex buffer mapped at rendering time, preventing both the vertex shader from having access to the vertex and texture coordinates. Then, we bind the shader program only when rendering the first frame. There is thus no shader program bound for all subsequent frames, breaking rendering. Fix this by binding the vertex buffer where needed, when setting attribute buffers for the shader program, and binding the shader program for every frame. As we use a single vertex buffer, we could bind it at the beginning of paintGL() and keep it bound indefinitely. That would however fail to clearly indicate in the source code where the vertex buffer is needed, making the code more difficult to understand as it would rely on implicit assumptions. Release the vertex buffer explicitly when we don't need it anymore to avoid this. While at it, fix a coding style violation by adding missing curly brackets.

2024-09-11qcam: viewfinder_qt: Draw the letterbox background blackLaurent Pinchart
When the widget's aspect ratio doesn't match the camera aspect ratio, the viewfinder is rendered letter-boxed. The side rectangles are not painted by the viewfinder, and Qt thus renders the parent widget background to fill that space. To make it black, we have two options: - The simplest option is to set the widget's autoFillBackground property to true. This causes Qt to paint the whole widget with its background colour before calling paintEvent(). As the camera image typically covers most (if not all) of the viewfinder widget, this is less efficient. - The more complicated option is to paint the letterbox rectangles manually. We can additionally set the widget's WA_OpaquePaintEvent attribute to instruct Qt to skip painting the parent widget. This reduces CPU usage by about 1% (and may reduce GPU usage as well). Note that the WA_OpaquePaintEvent attribute has to be disabled when we render the stopped icon, as the icon has a transparent background.

2024-07-31libcamera: Avoid variable-length arraysLaurent Pinchart
Unlike in C where they have been standardized since C99, variable-length arrays in C++ are an extension supported by gcc and clang. Clang started warning about this with -Wall in version 18: src/libcamera/ipc_unixsocket.cpp:250:11: error: variable length arrays in C++ are a Clang extension [-Werror,-Wvla-cxx-extension] 250 | char buf[CMSG_SPACE(num * sizeof(uint32_t))]; | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ One simple option is to disable the warning. However, usage of VLAs in C++ is discouraged by some, usually due to security reasons, based on the rationale that developers are often unaware of unintentional use of VLAs and how they may affect the security of the code when the array size is not properly validated. This rationale may sound dubious, as the most commonly proposed fix is to replace VLAs with vectors (or just arrays dynamically allocated with new() wrapped in unique pointers), without adding any size validation. This will not produce much better results. However, keeping the VLA warning and converting the code to dynamic allocation may still be slightly better, as it can prompt developers to notice VLAs and check if size validation is required. For these reasons, convert all VLAs to std::vector. Most of the VLAs don't need extra size validation, as the size is bound through different constraints (e.g. image width for line buffers). An arguable exception may be the buffers in IPCUnixSocket::sendData() and IPCUnixSocket::recvData() as the number of fds is not bound-checked locally, but we will run out of file descriptors before we could overflow the buffer size calculation.

2023-04-26apps: cam: kms_sink: Drop unique_ptr<> from DRM::AtomicRequestUmang Jain
There is no need to wrap DRM::AtomicRequest in std::unique_ptr<> in KMSSink::start(). Remove it so that the syntax becomes similar to what we have in KMSSink::stop(). No functional changes intended.

2022-12-09lc-compliance: simple_capture: Free Requests properlyPaul Elder
In the simple capture tests, in the capture functions, the Requests were auto-deallocated by the function going out of scope after the test completed. However, before the end of the scope, the Framebuffers that the Requests referred to were manually freed. Thus when the Requests were deallocated, they tried to cancel their Framebuffers, which involve setting the status to cancelled, which obviously causes a segfault because the Framebuffers had already been freed. Fix this by moving the list of Requests to a member variable and deallocating them before deallocating the Framebuffers at stop() time.

The parameter 'request' is only used in an assert. assert is only defined for debug builds and release builds will not use the parameter, resulting in warnings messages only for non-debug builds. Fix this by flagging the parameter as 'maybe_unused'.
