<para>Why are there so many dependencies ?</para>

<answer>

<para>
|
|
Making a full-featured media framework is a huge undertaking in itself.
|
|
By using the work done by others, we both reduce the amount of redundant work
|
|
being done and leave ourselves free to work on the architecture itself
|
|
instead of working on the low-level stuff. We would be stupid not to reuse
|
|
the code others have written.

However, do realize that in no way you are forced to have all dependencies
|
|
installed. None of the core developers has all of them installed. GStreamer
|
|
has only a few obligate dependencies : GLib 2.0, popt >= 1.6.0, and very
|
|
common stuff like glibc, a C compiler, and so on. All of the other
|
|
dependencies are optional.

Does GStreamer use GTK+ 1.2/GLib 1.2 or GLib 2.0 ?
|
|
</para>
|
|
</question>
|
|
|
|
<answer>
|
|
<para>
|
|
Since the 0.3.3 release of GStreamer, we use GLib 2.0 as the core library
|
|
for GStreamer, which features a move of GObject from GTK+ 2.0 to GLib 2.0.
|
|
If you want to compile using GTK+ 1.2/GLib 1.2, you need to get the
|
|
0.3.1 or earlier release. It is of course not supported.

Does GStreamer offer support for DVD decoder cards like dxr2/3 ?

<answer>

<para>

We do have support for the dxr3, although dxr2 support is unknown.
|

GStreamer can easily accomodate hardware acceleration by writing new
|
|
device-specific elements.

<question id="dependencies-x">
|
|
<para>Is GStreamer X independent ?</para>
|
|
</question>
|
|
|
|
<answer>
|
|
<para>
|
|
Yes, we have no X dependency in any of our core modules. There are GStreamer
|
|
applications that run fine without any need for X. However, until our Linux
|
|
Framebuffer or libsvga plugin is ready, you will not be able to play videos
|
|
without X. In the future, there will probably be lots of different output
|
|
plugins for video available.

</question>
|
|
|
|
<answer>
|
|
<para>
|
|
GStreamer actively supports such efforts, and in the case of
|
|
<ulink url="http://ladspa.org/"><citetitle>LADPSA</citetitle></ulink>,
|
|
we already have a wrapper plugin. This wrapper plug-in detects the LADSPA
|
|
plugins present on your system at register time.

</question>

|
<answer>
|
|
<para>
|
|
Not yet. The GStreamer architecture should be able to support the needs of
|
|
MIDI applications very well however. If you are a developer interested in
|
|
adding MIDI support to GStreamer we are very interested in getting in touch
|
|
with you.

<question id="dependencies-gnome">
|
|
<para>Does GStreamer depend on GNOME ?</para>
|
|
</question>
|
|
|
|
<answer>
|
|
<para>
|
|
No. But many of the applications developed for GStreamer do, including our
|
|
sample applications. There is nothing hindering people from developing
|
|
applications using other toolkits however and we would happily help promote
|
|
such efforts. A good example of an application using GStreamer, but which is
|
|
not using GNOME is the
|
|
<ulink url="http://mozstreamer.mozdev.org"><citetitle>
|
|
Mozstreamer</citetitle></ulink> which uses Mozilla XUL.
