Add a new privacy indicator

[emersion]

Use PipeWire to figure out when the microphone, camera, or screen capture is in use.

I've started work a privacy indicator. I checked my setup though and my camera doesn't appear to be used by pipewire (although I see it listed). Applications are using it directly (the webcam shows up in v4l).

Other drivers:

• [ ] pipewire (audio capture/mic)
• [ ] pipewire (screen capture)
• [ ] pipewire (webcam)
• [ ] pulseaudio (audio capture/mic)?

Note, more applications should move to PipeWire for camera as the ecosystem moves to libcamera. But yeah, it's still the early days.

Is there something left not implemented in #1982?

[bim9262]

This issue was about pipewire monitoring. If someone wants to add another driver another issue can be opened.

Thank you for working on this!

You're welcome, it was a fun block to work on

I'm trying to use this (Because it's really cool!) however I noticed the docs say pipewire Options (requires the pipewire feature to be enabled). Unfortunately it doesn't mention which feature as far as I can tell and audio/screencapture don't seem to be working. I read through the PR but I'm still not quite sure what I should be enabling or if these features should work like I'm expecting. Is there additional documentation I should be looking at or does anyone here have any suggestions?

EDIT: Some clarification:

This works fine:

[[block]]
block = "privacy"
[[block.driver]]
name = "v4l"

Both of these don't work and return Configuration error, probably because block.driver v4l is required per the docs. Or maybe because pipewire isn't configured correctly?

[[block]]
block = "privacy"
[[block.driver]]
name = "pipewire"

[[block]]
block = "privacy"
[[block.driver]]
name = "v4l"
[[block.driver]]
name = "pipewire"

Thanks!

@kevenwyld you have to compile with -F pipewire flag.

@kevenwyld you have to compile with -F pipewire flag.

That worked perfectly, thanks!
