In Pipewire and Gstreamer terminology Weston is a "live" source (as we
do not explicitly set PW_KEY_STREAM_IS_LIVE to false).
Such sources, be it compositors, cameras or microphones, usually set
the current system time as timestamps on buffers in order to make life
easier for consumers. Thus let's do so as well.
This notably helps when recording using `gstpipewiresrc` with the
`keepalive-time` property set.

instead of the output mode. The mode doesn't say anything about the
actual output geometry which could lead to buffers extending the output
region on rotated monitors. This now also works with moving the window
to different monitors.

As of PipeWire version 0.3.69, the gstpipewiresrc element uses the
existence of a modifier as a trigger to select dmabuf memory, failing
caps negotiation as we don't send DMA buffers yet.
Remove the linear modifier for now, to be added back when we add dmabuf
support to the PipeWire backend. This allows testing the PipeWire
backend with current GStreamer + PipeWire.

Pass the backend instead of the compositor to the PipeWire output API
create_head() method and increment the API version.
That way the backend will not have to find the backend pointer from the
compositor. This is trivial now, but in the multi-backend case would
entail iterating over all backends to find the correct one.

Now that our process-launching internals are identical between the
(still-misnamed) weston_client_launch and the frontend's Xwayland
launcher, we can reuse the internals instead of open-coding it.
As a result, we now additionally prevent Xwayland from inheriting
Weston's signal mask, by clearing SIG_UNBLOCK on all signals. This
should have no observable effect as we do not depend on signal handling
within Xwayland, instead using the displayfd readiness mechanism since
c2f4201ed2.

weston_client_start() takes only a single path with no arguments,

Use assert() to check for invalid NULL arguments. Something like that happens
during development and assert() makes it easier to find the error. And it avoids
unnecessary additional error handling.
The hmi-controller asserted anyways so this just moves the assert on level
deeper. Other controller probably do the same thing, or don't check the return
values at all.

The return values for most of the API functions will be removed and replaced by
asserts. So remove the return value checks. The end result will be the same:
These functions only fail for incorrect API usage, so basically the asserts are
moved from the hmi-controller into the shell.

There are V4L2 devices that will output NV12 but will do so using one dma
buffer. To support this, we need to add the same dma buffer twice but with
a different offset for the chrominance plane.
Also supports situations of 3 planes (e.g. YU12) inside a single dma buffer.

Add a separate PipeWire backend based on the PipeWire plugin. The backend
requires PipeWire 0.3.x.
The PipeWire backend can be used as a standalone-backend backend for streaming
and composing Wayland clients to PipeWire.
The backend supports the on-demand creation of heads via the
weston_pipewire_output_api_v1. It also supports per-output pixel format
configuration via a gbm-format option.
Multiple PipeWire outputs can be created by setting the num-outputs option in
the [pipewire] section.

Currently, if a head is detached, the entire state of the device is invalidated
to make sure that the connector is disabled on the next atomic commit. Side
effect of the invalid state is that all planes are disabled on the next commit.
This includes planes that are used with a different head that is not part of the
next atomic commit. Disabling the planes of unrelated outputs causes a blanking
of these outputs until output is repainted and the plane is reenabled.
Store the detached heads in a list on the output and disable the connectors for
all heads in this list in the next atomic commit.

I tried this, and it causes a crash. Leave a note for the future when we
happen to use some other backend with xwayland and find a "leak".
The reason this is a comment and not a Gitlab issue is that you probably
would not go looking for a Gitlab issue saying an idea is a bad one.
This comment is more likely to be found.
It's not really a leak either, it only needs to be fixed if you want a

We have a string describing the ICC profile. cmsGetProfileVersion()
returns a float value, and we are converting that to string with "%f"
and saving to this description. Instead, use "%.1f" to restrict it to a
single decimal value, which is enough. With this change we have e.g.
"version 4.4" instead of "version 4.4000000".
