pipewire: Add recipe

[jwillikers]

PipeWire is a project that aims to greatly improve handling of audio and video under Linux.

Fixes #18533.

Requires the following for optional ffmpeg support to be enabled.
This support won't be enabled by default, so it shouldn't be required to merge this PR.
Fyi, the support for ffmpeg should never be enabled by default because it will cause circular dependencies since ffmpeg requires sdl which now requires pipewire.

A source-code comment explaining the purpose of this would be nice.

[jwillikers]

Done.

[valgur]

Thanks!

[valgur]

Are the extra for loops really necessary?

Suggested change

	for dependency, _value in self.dependencies.direct_host.items():
	if dependency.ref.name == "linux-headers-generic":
	for includedir in self.dependencies.direct_host[
	"linux-headers-generic"
	].cpp_info.includedirs:
	tc.c_args.append(f"-I{includedir}")
	break
	for includedir in self.dependencies["linux-headers-generic"].cpp_info.includedirs:
	tc.c_args.append(f"-I{includedir}")

[jwillikers]

For some reason, I think that I had trouble with this a while ago. Oh, it came back to me. I did it this way because otherwise, using a platform_requires for linux-headers-generic will cause this to fail.

[valgur]

Absolute nitpicking, but could you set the column limit to 100 or 120 for black, please?
The line wrapping is a bit excessive and only hurts readability, imo.

[jwillikers]

I reformatted with a longer line length with Ruff. It would be great to have formatting configured for the repository so no one has to think about this kind of thing.

If your IDE supports .editorconfig then it is configured

conan-center-index/.editorconfig

Line 12 in 2c3904f

max_line_length = 200

For this reason you might find that not all the references have been launched or not all the configurations for a given reference. Also, take into account that we cannot guarantee the order of execution as it depends on CI workload and workers availability.}
