Availability
============
Built for all supported architectures. In sync with Debian.

Rationale
=========
GNOME switched to Wayland by default in the 3.22 release 2 years ago. Ubuntu followed that lead and defaulted to Wayland with 17.10 but switched back to X for 18.04 LTS. One key feature that the Ubuntu Desktop team supports with X and wants to continue supporting with Wayland is remote desktop. Therefore, I think this MIR is a blocker to enabling Wayland by default for 20.04 LTS.

pipewire is a new ambitious library and service for audio and video. It aims to take PulseAudio to the next level and provide a similar capability for video. One reason it was created was to help with sandboxing for Flatpak and to handle Wayland applications. pipewire is required for GNOME's remote desktop implementation for Wayland.

So at this point, we are interested in the video part for remote desktop. The audio part is expected later. I don't think even Fedora is using the audio part yet.

GNOME Remote Desktop
====================
To enable GNOME's remote desktop feature in Ubuntu, you need:
- Build mutter with --enable-remote-desktop
This has been done in Debian but we need pipewire in Ubuntu main to enable on Ubuntu

- Install gnome-remote-desktop (MIR bug not filed yet)

- I suggest uninstalling vino to make sure you will be using gnome-remote-desktop

- Restart your computer

- Log in to the Ubuntu on Wayland session.
I believe it should work on X too but there is a misconfiguration in GNOME:
https://gitlab.gnome.org/GNOME/gnome-control-center/issues/212

- Open the Settings app to the Sharing page. Turn on Sharing in the app's top bar.
Click Screen Sharing and turn it on.

Only VNC is supported at this time.

Use remmina (Ubuntu's default app) or another VNC client like Remmina to connect from another computer.

Security
========
No known security issues

https://security-tracker.debian.org/tracker/source-package/pipewire
https://launchpad.net/ubuntu/+source/pipewire/+cve

I expect the Security Team will want to review this MIR.

Quality assurance
=================
- Ubuntu Desktop bugs needs to be subscribed

https://bugs.launchpad.net/ubuntu/+source/pipewire
https://bugs.debian.org/cgi-bin/pkgreport.cgi?src=pipewire
https://github.com/PipeWire/pipewire/issues/

No autopkgtests. No build tests.

Dependencies
============
NOTE: We don't need libspa-ffmpeg which depends on ffmpeg libraries which are not allowed in main.

All the other binary dependencies are already in main.

Standards compliance
====================
4.1.3, debhelper compat 11, simple dh7 style rules

Maintenance
===========
Maintained in Debian by the Debian Utopia team, which is a small team focused on cross-desktop freedesktop.org stuff.

upstream:
https://pipewire.org/
https://github.com/PipeWire/pipewire

Other Info
==========
Fedora 29 ships GNOME Remote Desktop by default. I think Debian Buster "10" GNOME will include it by default too.
