2024-09-12libcamera: v4l2_videodevice: Improve readabilityStefan Klug
The handling for the sequence number validation within V4L2VideoDevice::dequeueBuffer makes use of a std::optional, which can be used as a boolean in conditional statements. This has the impact in this use case that it can be mis-read to be interpretting the value for firstFrame_ which is assigned as the buf.sequence. Remove this potential for confusion by making it clear that the first frame handling is only performed when firstFrame_ does not have a value assigned.

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.

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.

V4L2VideoDevice::open() creates an EventNotifier and this notifier needs to be created from the CameraManager thread. Use invokeMethod() for pipe_->acquire() and pipe_->release() so that the EventNotifiers are created from the CameraManager thread context.

Drop PipelineHandler::lock_ this now is no longer necessary and update the "\context" part of the documentation for acquire[Device]() and release[Device]() to match.
