Adding 'media-video/vlc -opus' |
| 19 |
to /etc/portage/profile/package.use.stable.mask will override, to let |
| 20 |
you use the flag with VLC. (The '-' is not a typo. It's there |
| 21 |
because '-opus' removes opus from the masked flags.) |

I tried to figure out the other day why opus is stable-masked for VLC |
| 24 |
and wound up in a maze of bugs. I'm sorry I don't have the bug numbers |
| 25 |
for them. If you want to dive into the maze, grep around |
| 26 |
in /usr/portage/profiles for vlc and opus. |
| 27 |

I'm pretty sure what happened was that vlc had a security issue, and a |
| 29 |
new version had to be stabilized, some time in 2014 or early 2015. At |
| 30 |
that point, for opus support the new stable VLC required an unstable |
| 31 |
opus, so they stable-masked the flag for VLC. Later, a new-enough opus |
| 32 |
was stabilized; at that point, the flag for VLC should have been |
| 33 |
unmasked, but it fell through the cracks. There was already whining in |
| 34 |
bug comments about it not getting done, so I didn't add my voice. |
