SimpleCameraConfiguration::validate() adjusts the configuration of its
streams (if the size is not in the outputSizes) to the captureSize. But
the captureSize itself can be not in the outputSizes, and then the
adjusted configuration won't be valid resulting in camera configuration
failure.

The V4L2Subdevice class deals with streams in two places:
- In routing tables, streams as expressed as a pad number and a stream
number in a v4l2_subdev_route instance.
- In the format and selection get and set functions, streams as
expressed using the Stream structure, which binds the pad number and
stream number.
Expressing streams in different ways requires pipeline handlers and
other helpers to convert between the two representations. This isn't
much of an issue yet as libcamera has little stream-aware code, but it
is expected to increasingly become a burden.
To simplify the API, introduce a V4L2Subdevice::Route structure that
mimicks the kernel v4l2_subdev_route structure but represents streams as
V4L2Subdevice::Stream instances. This will improve seamless integration
of routes, formats and selection rectangles.

Meson uses tags to sort installed files in categories, and makes it

but can't always do so properly. Mark the install targets that meson

If the pipeline runs out of embedded data buffers, then it will pass

with the subsequent algorithms if the sensor did not action the

which can be passed in lieu of the metadata.

As the self-path is limited in output resolution to 1920x1920,
generating a configuration using the self path limits the maximum
stream size to 1920x1920, while higher resolutions can be obtained by
using the main path.
