The file is not useful without `libcamera-source.cpp` because it
uses symbols only defined there. And being a non-self-contained
source file, it also breaks clangd. So move its contents directly
to `libcamera-source.cpp`. This makes the file about 2200 lines long,
but I feel that is still manageable (and it is by far not the longest).
(cherry picked from commit 1a1cf55efb)
libcamera says that cameras should default to manual focus mode. This
means that unless pipewire clients specifically change this control,
users with an autofocus-capable camera are left with an out-of-focus
image. This patch sets the autofocus mode to continuous and enables
auto-exposure (as the default for this is unspecified).
Testing with an imx708 on Raspberry Pi OS on a Raspberry Pi 4, before
this patch the image was generally out of focus in Firefox/webrtc, after
this patch autofocus works correctly.
(cherry picked from commit 3a0ffe21e6)
Add an index offset when enumerating controls. We insert 2 properties
before enumerating the controls so the index of the first control needs
to have an offset of 2.
Can be used to group ports together. Mostly because they are all from
the same stream and split into multiple ports by audioconvert/adapter.
Also useful for the alsa sequence to group client ports together.
Also interesting when pw-filter would be able to handle streams in the
future to find out what ports belong to what streams.
C++20 introduced designated initializers similar to the ones found
in C99, however, in C++ designated initializers cannot be mixed
with non-designated initializers. GCC rejects mixed initializers
with an error.
The drm format modifier value `0` is actually `DRM_FORMAT_MOD_LINEAR`,
a commonly used modifier. Unfortunately there appears to be no value
that can savely used as placeholder for "no value", as e.g.
`DRM_FORMAT_MOD_INVALID` is often used to indicate an implicit modifier.
Thus add an extra field that clearly indicates whether the modifier
value is set or not, add it to the util fuctions and use it for the
current only user, the libcamera backend.

libcamera can detect camera transforms/rotation, e.g. from the device
tree, and makes that information usable for clients via
`CameraConfiguration::transform`.
Advertise this information via the VideoTransform meta so Pipewire
clients can adjust their output accordingly.
Rotated cameras are common in mobile devices such as the Pinephone Pro,
which was used to test this feature.
Using a shared_ptr removes the need for manually calling
`libcamera_manager_release()` to drop the reference as it is done
automatically whenever the shared_ptr is destroyed or reset.
The PropInfo either has a registered id (and then also a name from the
type-info) or a custom name as a string.
In all cases, the description contains a free form text that clarifies
the property.
Use the description in the stream controls name.
Make the alignment parameter optional when negotiating buffers.
Default to a 16 bytes alignment and adjust for the max cpu
alignment.
Remove the useless align buffer parameter in plugins, we always
set it to 16 anyway.
Keep track of the negotiated parameters and use those to construct
the Buffers param.
Use the FrameAllocator to allocate buffer memory. Keep a request for
each buffer and queue them.
In requestComplete, put the request metadata info into the buffer and
header and write the finished buffer id to a ringbuffer. Then wake up
the data thread to pop the finished buffer_id and push it in the
graph.
Remove some old files.
