Description Jan Hrabe 2008-09-09 17:50:44 UTC
I have a minimal kde desktop, without arts daemon.  Then I have a kde multimedia application juk which can use gstreamer libraries.  Finally, I have the alsa sound system (and alsa use variable).  I would therefore expect that the necessary package gst-plugins-alsa gets automatically pulled in by one of these other packages, most logically by the gstreamer package.  However, it doesn't. 

For a user who simply wants to emerge juk and use it, it's not trivial to figure out that this plugin is needed as well.  Furthermore, the emerge --depclean will refuse to remove it after explicit installation, even after it may not be needed any more.

Comment 1 Jeroen Roovers (RETIRED) gentoo-dev 2008-09-10 04:38:46 UTC
Let's see - kde-base/juk depends on media-libs/gst-plugins-base which inherits the gst-plugins-base eclass which has IUSE=alsa and inherits gst-plugins10. You would assume that somewhere along the line an ALSA gstreamer plugin is built.
Comment 2 Jan Hrabe 2008-09-10 14:15:19 UTC
Yes, that's what I would assume but it does not get built.  I had to emerge gst-plugins-alsa manually.
Comment 3 Dror Levin (RETIRED) gentoo-dev 2008-10-19 18:17:59 UTC
I can confirm this - I have kde+alsa and had no sound using gstreamer.
I have gstreamer, gst-plugins-base and gst-plugins-good and no alsasink element:
# gst-launch-0.10 audiotestsrc ! audioconvert ! audioresample ! alsasink
WARNING: erroneous pipeline: no element "alsasink"                               

After emerging gst-plugins-alsa it now works.
As you can see, there is no alsa use flag:

Comment 4 Olivier Crete (RETIRED) gentoo-dev 2009-03-30 06:06:45 UTC
Separate plugins strike again, currently, each GST using app should depends on any plugin it may ever need... 
Comment 5 Olivier Crete (RETIRED) gentoo-dev 2009-04-20 22:09:00 UTC
if you want alsa and stuff, you should depend on gst-plugins-meta

Depedencies adjusted with the help of Samuli Suominen (sound herd). Thanks
