The conversions back and forth between GStreamer colorimetry and
libcamera color space are not invariant for the bt601 colorimetry.
The reason is that Rec709 transfer function defined in GStreamer
as GST_VIDEO_TRANSFER_BT709 (5), is to be replaced by its alias
GST_VIDEO_TRANSFER_BT601 (16) only for the case of bt601 (aka 2:4:16:4)
colorimetry - see [1].
Currently the composition of the GStreamer/libcamera conversions:
colorimetry_from_colorspace (colorspace_from_colorimetry (bt601))
returns 2:4:5:4 instead of the expected 2:4:16:4 (bt601). This
causes negotiation error when the downstream element explicitly
expects bt601 colorimetry.
Minimal example to reproduce the issue is with a pipeline handler
that do not set the optional color space in the stream configuration,
for instance vimc or imx8-isi:
export LIBCAMERA_PIPELINES_MATCH_LIST="vimc,imx8-isi"
gst-launch-1.0 -v libcamerasrc ! video/x-raw,colorimetry=bt601 ! fakesink
Above pipeline fails to start. This change memorizes downstream required
transfer function when mapped libcamera transfer is Rec709 in
gst_libcamera_configure_stream_from_caps(), and restores the transfer
function in gst_libcamera_stream_formats_to_caps().

Software ISP is currently fully automatic and doesn't allow image
modifications by explicitly set control values. The user has no means
to make the image looking better.
This patch introduces support for contrast control, which can improve
e.g. a flat looking image. Based on the provided contrast value, it
applies a simple S-curve modification to the image.
The contrast algorithm just handles the provided values, while the
S-curve is applied in the gamma algorithm on the computed gamma curve
whenever the contrast value changes. Since the algorithm is applied
only on the lookup table already present, its overhead is negligible.
The contrast value range is 0..2 and corresponds to the whole range from
a completely flat contrast to an infinite contrast, 1.0 being the normal
value. This makes the user visible range intuitive and easy to use in
GUI sliders, while complying with Contrast control definition. There is
no unified range in the hardware pipelines, for example rkisp1 uses
0..1.993 range while rpi uses 0..10 range.
This is a preparation patch without actually providing the control
itself, which is done in the following patch.

So far the mali-c55 pipeline has only supported cropping without using
the scaling functionalities.
Now that the kernel has gained support for the scaling operations, make
the libcamera pipeline use it by combining it with a first cropping step
to align the input and output images FOV ratio, and then scale to the

At present we configure raw streams by looping through the pixel
formats we support and finding one with an associated media bus
format code that the sensor can produce. In the new representation
of raw data from the kernel driver this will not work - the sensor
could produce 8, 10, 12, 14 or 16 bit data and the ISP will force
it to RAW16, which is the only actually supported output.
To fix the issue move to simply finding a pixel format with a bayer
order that matches that of the media bus format produced by the
sensor. If the sensor can produce multiple formats with the same
bayer order use the one with the largest bitdepth.
Finally, remove the claim to support RAW formats of less than 16 bits.

The latest version of the Mali C55 driver has changed the format
accepted by the ISP sink pad to be the 20-bit wide.
The CSI-2 receiver handles the format expansion internally by
propagating the sensor produced format from its sink to the 20-bit
expanded version on its source pad.
Instead of re-applying the sensor format to the CSI-2 receiver source
pad (which is now an invalid operation) read from there the format
propagated by the driver internally and further propagate it to the ISP
subdevice.

The Matrix constructor that takes a std::vector is meant and only used
to initialize a Matrix from an initializer list. Using a std::vector is
problematic for two reasons. First, it requires constructing a vector,
copying the data from the initializer list, which is an expensive
operation. Then, the vector size can't be verified at compile time,
making the constructor unsafe.
The first issue could be solved by replacing the vector with a
std::initializer_list or a Span. The second issue would require checking
the initializer list size with a static assertion, or restricting usage
of the constructor to fixed-extent spans. Unfortunately, even if the
size of initializer lists is always known at compile time, the
std::initializer_list::size() function is a compile-time constant only
for constant initializer lists. Using a span would work better, but
construction of a fixed extent span from an initializer list must be
explicit, making the API cumbersome.
We can solve all those issues by passing an std::array to the
constructor. Construction of an array from an initializer list can be
implicit and doesn't involve a copy, and the array size is a template
parameter and therefore guaranteed to be a compile-time constant.

of seconds, and then later slowly gets to normal. This is because existing

Fix the problem by using in frameContext sensor values, since we already
use those in blc algorithm and change exposure type to int32_t to
unnecessary castings.
