No, || means "any of", see [1]. And I believe in that case portage will translate |
| 23 |
it to "any-of" or something like that. These are just nested conditionals. It can |
| 24 |
be confusing even for someone with programming background. I suppose portage |
| 25 |
could translate that into a more human friendly form but with many nesting levels |
| 26 |
it will get ugly any way you put it. |
| 27 |
|
| 28 |
And yes, dec_av2 is what he needs (unless he doesn't need x264 and x265 support). |
| 29 |
I was just clearing the point about the meaning of the message. |
