Bug#689353: gstreamer0.10-plugins-good: put providers of audio/video sinks/sources in extra packages

[Dominik George]

Package: gstreamer0.10-plugins-good
Version: 0.10.31-3
Severity: normal

Some packages depend on gstreamer0.10-alsa | gstreamer0.10-audiosink or
comparable because they need a gstreamer sink/source plugin of some
sort. Unfortunately, far too many packages provide the virtual
gstreamer0.10-audiosink package.

For example, most systems use ALSA because it is the Debian default
sound system. So the GStreamer plugin to be isntalled would be
gstreamer0.10-alsa.

However, in many circumstances, for example the task-xfce-desktop,
gstreamer0.10-plugins-good is pulled in before a package depending on
-audiosink is being installed. xfce4-mixer is such a case - when
installing task-xfce-desktop, gstreamer0.10-plugins-good is installed as
a dependency of some package. When it comes to installing xfce4-mixer,
gestreamer0.10-plugins-good provides -audiosink thus fulfilling the
dependency. The required gstreamer0.10-alsa never gets installed.

Therefore, the audio/video sink/source virtual packages should not be
provided at such large scale. The user should be able to choose their
backend, but if they didn't choose a specific audiosink for example,
-alsa must get a chance to really get pulled in.

This also affects gstreamer0.10-plugins-bad.
