Consider installing ubuntu-restricted-addons by default
The Pop!_OS 17.10 Beta Installer skips the Install Additional Software page of Ubuntu's installer.
If a user clicks the checkbox, ubuntu-restricted-addons would be installed. Maybe Pop!_OS should install that package by default?
Here's what it installs:
$ apt show ubuntu-restricted-addons
Recommends: chromium-codecs-ffmpeg-extra, gstreamer1.0-fluendo-mp3,
gstreamer1.0-libav, gstreamer1.0-plugins-ugly, gstreamer1.0-vaapi
We had some concerns over the legality of distributing those, and have seeked legal advice.
Base Ubuntu installation has the option to automatically install these codecs after the system installation is completed. It also offered the option to have it run updates too.
These things happen after the system is installed, but before rebooting and giving the OS to the user. So from the user's point of view, it does it as part of the installation.
Could that be a solution?
I'm not professionally comfortable with installing proprietary software on every installation by default, with no obvious way to opt-out. While I'm not personally, inherently against running proprietary software, I don't think that's a choice that a distributor should be making on behalf of their users.
