Two reasons: |
| 15 |
|
| 16 |
1. Compatibility. USE=ffmpeg is already used for || ( libav ffmpeg ) in |
| 17 |
a lot of packages. If we changed the meaning, libav users will end up |
| 18 |
switching '-ffmpeg libav' per-package. Ugly. |
| 19 |
|
| 20 |
2. Feature-oriented flags. USE=ffmpeg represents the generic feature, |
| 21 |
USE=libav is auxiliary implementation-switch flag. Well, maybe we could |
| 22 |
use, say, USE=avcodec to avoid ambiguity but that's a larger change. |
