2022-06-29ipa: libipa: algorithm: Add an algorithm registration mechanismLaurent Pinchart
In order to allow dynamic instantiation of algorithms based on tuning data files, add a mechanism to register algorithms with the IPA module. The implementation relies on an AlgorithmFactory class and a registration macro, similar to the pipeline handler registration mechanism. The main difference is that the algorithm registration and instantiation are implemented in the Module class instead of the AlgorithmFactory class, making the factory an internal implementation detail.

When the libcamera project was started, we had no public git tree hosted on git.libcamera.org. The problem has been addressed a while ago, and the git.linuxtv.org libcamera repository is now a mirror of the main git tree. The mirror is useful to benefit from the linuxtv.org automated compile tests, but it can also confuse users who don't know where the official version is. To try and clarify this, use the git.libcamera.org URL consistently through the project.

2021-09-07libcamera: v4l2_videodevice: Drop toV4L2PixelFormat()Laurent Pinchart
The V4L2VideoDevice::toV4L2PixelFormat() function is incorrectly implemented, as it will pick a multi-planar format if the device supports the multi-planar API, even if only single-planar formats are supported. This currently works because the implementation calls V4L2PixelFormat::fromPixelFormat(), which ignores the multiplanar argument and always returns a single-planar format. Fixing this isn't trivial. As we don't need to support multi-planar V4L2 formats at this point, drop the function instead of pretending everything is fine, and call V4L2PixelFormat::fromPixelFormat() directly from pipeline handlers. As the single-planar case is the most common, set the multiplanar argument to false by default to avoid long lines.

It can be useful to connect a signal to a functor, and in particular a lambda function, while still operating in the context of a receiver object (to support both object-based disconnection and queued connections to Object instances). Add a BoundMethodFunctor class to bind a functor, and a corresponding Signal::connect() function. There is no corresponding disconnect() function, as a lambda passed to connect() can't be later passed to disconnect(). Disconnection typically uses disconnect(T *object), which will cover the vast majority of use cases.
