When the AWB engine doesn't find a valid pixel because all pixels lie
outside the configured colour range it returns an AWB measurement value
of 255, 255, 255. This leaves the regulation in an unrecoverable state
noticeable by a completely green image. Fix that by skipping the AWB
calculation in case there were no valid pixels.

GStreamer video-info calculated stride and offset may differ from
those used by the camera.
For stride and offset mismatch, this patch adds video meta to buffer
if downstream supports VideoMeta through allocation query. Otherwise,
create a internal VideoPool using the caps, and copy video frame to
this system memory.

With the newly introduced `SDLTexture1Plane` it is easy to handle
any single-plane format that has an SDL equivalent. So use it for
more YUV and RGB formats.
The mapping of RGB formats is not entirely straightforward because
`SDL_PIXELFORMAT_ZZZ...888...` defines a format where the order of
the components is endian dependent, while libcamera's `ZZZ...888...`
formats are derived from the matching DRM formats, and the RGB formats
in question are defined to be little-endian there. So the
endian-independent `SDL_PIXELFORMAT_{ZZZ24,ZZZZ32}` are used.

`SDLTextureYUYV` uses `SDL_PIXELFORMAT_YUY2`, which is a single plane
format. To support other single plane formats, replace `SDLTextureYUYV`
with `SDLTexture1Plane` that can be instantiated with an arbitrary SDL
pixel format and that uses `SDL_UpdateTexture()` to update the texture
using exactly a single plane.

In commit ee2b011b65c6 ("apps: cam: Try raw role if default viewfinder

This was unfortunately added by directly accessing the vector rather
than extending the size when the vector is empty. Fix the code to push

The introducing commit (dff416a84b78 ("README: Add missing package for

would get the following messages:
Program /usr/lib/x86_64-linux-gnu/qt5/bin/lrelease found: NO
Program lrelease-qt5 found: NO
Program lrelease found: NO found but need: '== 5.14.2'
That was the case for qt5 and is still true for qt6 but this actually
is neither breaking the build nor is it doing anything to the outcome
of the build (for both qt5 and qt6) as qcam is bit to bit identical
with and without that package.
Therefore, let's not mislead users to install an unnecessary package.

The problem occurs when the calculation could lead to a final row (or
column) of grid squares with no pixels in them (and hence, NaNs).
One specific case is a Pi 5 with an image width (or height) of 1364,
so that's 682 Bayer quads. To give 32 grid squares it was calculating
22 quads per cell. However, 31 * 22 = 682 leaving nothing in the final
column.
The fix is to do a rounding-down division by the number of cells minus
one, rather than a rounding-up division by the number of cells. This
turns the corner case from one where the final row/column has no
pixels to one where we don't quite cover the full image, which is how
we have to handle these cases.

cam currently defaults to the viewfinder role when no role is specified.
This means that on platforms that only support the raw role (such as a
raw sensor with no softISP on a simple pipeline platform),
generateConfiguration() would return nullptr and cam would bail out.
At least this is what is supposed to happen based on the little
documentation that we have written regarding generateConfiguration(),
specifically in the application writer's guide, which is probably the
most influential piece of documentation:
The ``Camera::generateConfiguration()`` function accepts a list of
desired roles and generates a ``CameraConfiguration`` with the best
stream parameters configuration for each of the requested roles. If the
camera can handle the requested roles, it returns an initialized
``CameraConfiguration`` and a null pointer if it can't.
Currently the simple pipeline handler will return a raw configuration
anyway (if it only supports raw) even if a non-raw role was requested.
Thus cam receives a raw configuration instead of a nullptr when no role
is specified and viewfinder is requested.
However, in the near future, support for raw streams with softISP on the
simple pipeline handler will be merged. This will notably change the
behavior of the simple pipeline handler to return nullptr if a non-raw
role was requested on a platform that only supports raw. This is proper
behavior according to documentation, but changes cam's behavior as it
used to capture fine with no parameters but will no longer be able to.
Technically this is an issue with the roles API, as we are mixing
roles in the sense of "configuration hints" (eg. viewfinder vs recording
vs still capture) with roles in the sense of "platform capabilities"
(raw vs everything else). In the long term the proper solution is to
rework the roles API.
In the meantime, fix cam so that it will try the raw role if the default
viewfinder role returns no configuration. cam is an app that is capable
of using the raw stream, so this is appropriate behavior. If roles are
specified, then do not retry, as in this situation the user knows what
streams they can use and what they want.

When libcamerasrc is negotiating with downstream element, it first
extracts colorimetry field from downstream supported caps, then set
this colorimetry to its stream configuration and propagates the
colorimetry downstream.
Currently libamerasrc only considers the case there is one colorimetry
in colorimetry field of downstream caps. But the issue is that
downstream caps may report a list of supported colorimetry, which
causes libcamerasrc to set unknown colorimetry to stream configuration
and negotiate fail with downstream element.
In order to fix the issue, need to fixate colorimetry field before
getting colorimetry string.

Defining the variables at the beginning of the function forces the types
to be default constructible, which may not be desirable; furthermore, it
also forces the move/copy assignment operator to be used when the
deserialized value is retrieved.
Having `T val = f()` has the advantage of benefitting from potential RVO
as well as not requiring `T` to be default constructible, so generate
code in that form by calling `deserialize_call()` with `declare=true`.

This reverts commit e85c7ddd38ce8456ab01c2a73baf9e788f6a462e.
Linux kernel predating 6.4 (specifically commit 7cfb35d3a800 ("media:
rkisp1: Implement ENUM_FRAMESIZES") do not have the ioctl in rkisp1
driver required to dynamically query the resizer limits.
Because of that, maxResolution and minResolution are both {0, 0}
(default value for Size objects) which means filterSensorResolution()
will create an entry for the sensor in sensorSizesMap_ but because the
sensor resolution cannot fit inside the min and max resolution of the
rkisp1, no size is put into this entry in sensorSizesMap_.
On the next call to filterSensorResolution(),
sensorSizesMap_.find(sensor) will return the entry but when attempting
to call back() on iter->second, it'll trigger an assert because the size
array is empty.
Linux kernel 6.1 is supported until December 2027, so it seems premature
to get rid of those hard-coded resizer limits before this happens.
Let's restore the hard-coded resizer limits as fallbacks, actual limits
are still queried from the driver on recent enough kernels.

If sphinx-build-3 binary is found on the host system, the documentation
is built, regardless of the value of the feature option.
This makes sure that sphinx-build-3 presence is only checked if the
documentation feature is not disabled (which is the default, as it's
"auto" by default).
This is essential for reproducibility for build systems where
sphinx-build-3 may or may not be present when libcamera is built, and
also to declutter the generated package if documentation isn't desired.

The meson documentation on the feature build options isn't clear if a
missing "value" is legal and if it is, what its default value is ([1]).
Therefore, let's make it explicit by using what is experimentally the
default: auto.
