<question id="dependencies-why-so-many">
|
|
<para>Why are there so many dependencies ?</para>

</question>
|
|

|
<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, liborc, and very
|
|
common stuff like glibc, a C compiler, and so on. All of the other
|
|
dependencies are optional.

<question id="dependencies-x">
|
|
<para>Is GStreamer X independent ?</para>
|
|
</question>
|
|
|
|
<answer>
|
|
<para>
|
|
Yes, we have no hard X dependency in any of our modules. There are many
|
|
GStreamer applications that run fine without any need for X, for example
|
|
streaming servers, transcoding applications, or audio applications that
|
|
don't output any video. Other applications output video to a framebuffer,
|
|
custom-made hardware sinks, or via wayland.

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

<question id="dependencies-midi">
|
|
<para>Does GStreamer support MIDI ?</para>
|
|
</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.
|
|
</para>
|
|
<para>
|
|
MIDI playback is provided by plugins such as wildmidi and timidity.

<question id="dependencies-gnome">
|
|
<para>Does GStreamer depend on GNOME or GTK+ ?</para>
|
|
</question>
|
|
|
|
<answer>
|
|
<para>
|
|
No. But many of the applications developed for GStreamer do, including some
|
|
of our sample applications. Other applications use the Qt toolkit, or are
|
|
written for Mac OS/X or Windows. We aim to provide API that is toolkit
|
|
agnostic and can be used from any toolkit, desktop environment or operating
|
|
system.
