I want to report a bug with the default video player in Ubuntu.
Based on this instructions I need to also know the program name. On the icon it's named "Videos" but using ubuntu-bug videos returns an error that the package isn't installed. That is the name of the app.

App Visible on the background using Alt+F2 to trigger an error reporting modal. That states there's no such app with that name

This isn’t obvious, but the GNOME Videos applications is also known as Totem, and the corresponding package is totem:
ubuntu-bug totem To find this out, the most reliable way, based on an application’s name in the launcher, is to find the corresponding launcher configuration file. Open a terminal, and run
grep -r Videos /usr/share/applications This will list /usr/share/applications/org.gnome.Totem.desktop; to find out which package supplies this file, run
dpkg -S /usr/share/applications/org.gnome.Totem.desktop 0
