Adding 'media-video/vlc -opus' to /etc/portage/profile/package.use.stable.mask will override, to let you use the flag with VLC. (The '-' is not a typo. It's there because '-opus' removes opus from the masked flags.) I tried to figure out the other day why opus is stable-masked for VLC and wound up in a maze of bugs. I'm sorry I don't have the bug numbers for them. If you want to dive into the maze, grep around in /usr/portage/profiles for vlc and opus. I'm pretty sure what happened was that vlc had a security issue, and a new version had to be stabilized, some time in 2014 or early 2015. At that point, for opus support the new stable VLC required an unstable opus, so they stable-masked the flag for VLC. Later, a new-enough opus was stabilized; at that point, the flag for VLC should have been unmasked, but it fell through the cracks. There was already whining in bug comments about it not getting done, so I didn't add my voice.
