Currently, I have an ebuild for a project of mine that needs gstreamer |
| 2 |
(1.x) to play videos. I have these deps: |
| 3 |
|
| 4 |
RDEPEND="(media-libs/gst-plugins-good:1.0 |
| 5 |
media-plugins/gst-plugins-libav)" |
| 6 |
|
| 7 |
DEPEND="media-libs/gst-plugins-base:1.0" |
| 8 |
|
| 9 |
During building, some headers from plugins-base are needed and libraries |
| 10 |
from that are linked directly, that's why that's in DEPEND and the |
| 11 |
others in RDEPEND. |
| 12 |
|
| 13 |
However, if the system has no gstreamer installation at all currently, |
| 14 |
then this will not install stuff like media-plugins/gst-plugins-pulse, |
| 15 |
which might be needed on a PulseAudio-enabled system. |
| 16 |
|
| 17 |
Should I also depend on media-plugins/gst-plugins-meta in order to make |
| 18 |
sure that this gets installed? |
| 19 |
|
| 20 |
Note that the project in question doesn't care at all about this |
| 21 |
low-level stuff. PulseAudio or ALSA for example doesn't matter. All the |
| 22 |
project knows about is the gstreamer API, plugins-good and plugins-base. |
| 23 |
|
| 24 |
Even plugins-libav is not used directly, but is a dep simply because |
| 25 |
that's the only way to get gstreamer to *hopefully* play all video |
| 26 |
formats correctly (assuming the user hasn't crippled libav by disabling |
| 27 |
USE flags in media-video/libav.) I wouldn't know how to prevent that |
| 28 |
from happening in the first place; for example, how do I make sure the |
| 29 |
ebuild can request all deps in a way that makes playback of H.264 or VC8 |
| 30 |
or Theora video possible. Again through plugins-meta? That lacks an h264 |
| 31 |
USE flag though (but does have an "ffmpeg" USE flag which pulls |
| 32 |
plugins-libav as a dep.) |
