What's up with that?</para>
</question>
<answer>
<para>
- GStreamer-0.8 and GStreamer-0.10 are the main version
+ GStreamer-0.10 and GStreamer-1.0 are the main version
'series' currently in use. For all practical purposes
you should think of them as two completely different libraries
which just happen to have a similar name. They can be installed
in parallel and are completely independent.

<para>
- For the 0.8 version you will need the 0.8 plugins and bindings
- (gst-plugins 0.8.x, gst-ffmpeg 0.8.x, gst-python 0.8.x etc.), while

not have to match exactly, only the major versions needs to be the
same (ie. it may be that the current gst-plugins-good version is

Odd-numbered versions such as 0.9.x, 0.11.x, etc. are unstable

<para>
- You should download GStreamer-0.10. GStreamer-0.8 is not developed
- any longer and has not been maintained for almost two years (you
- may still find it packaged for your disto though, but that's most
- likely for legacy applications).

First of all, verify that you have a working registry and that you can
inspect them by typing
<programlisting>
-$ gst-inspect fakesrc
+$ gst-inspect-1.0 fakesrc
</programlisting>
This should print out a bunch of information about this particular element.
If this tells you that there is "no such element or plugin", you haven't
that you really should have : fakesrc and fakesink. They do nothing except
pass empty buffers. Type this at the command-line :
<programlisting>
-$ gst-launch -v fakesrc num-buffers=3 ! fakesink
+$ gst-launch-1.0 -v fakesrc silent=0 num-buffers=3 ! fakesink silent=0
</programlisting>
This will print out output that looks similar to this :
<programlisting>
link the audiotestsrc element to an output element that matches your hardware.

Then try to play the sine tone by running
<programlisting>
-$ gst-launch audiotestsrc ! audioconvert ! audioresample ! osssink
+$ gst-launch-1.0 audiotestsrc ! audioconvert ! audioresample ! pulsesink

command-line tool, which comes standard with GStreamer.
Invoked without any arguments,
<programlisting>
-$ gst-inspect
+$ gst-inspect-1.0
</programlisting>
will print out a listing of installed plugins.
To learn more about a particular plugin, pass its name on the command line.
For example,
<programlisting>
-$ gst-inspect volume
+$ gst-inspect-1.0 volume
</programlisting>
will give you information about the volume plugin.

You access the GStreamer command line interface using the command gst-launch.

To automatically detect the right codec in a pipeline, try
<programlisting>
-gst-launch filesrc location=my-random-media-file.mpeg ! decodebin !
- audioconvert ! pulsesink
+gst-launch-1.0 filesrc location=my-random-media-file.mpeg ! decodebin !

-gst-launch filesrc location=my-random-media-file.mpeg ! decodebin !
+gst-launch-1.0 filesrc location=my-random-media-file.mpeg ! decodebin !
videoconvert ! xvimagesink
</programlisting>
Something more complicated:
<programlisting>
-gst-launch filesrc location=my-random-media-file.mpeg ! decodebin name=decoder
+gst-launch-1.0 filesrc location=my-random-media-file.mpeg ! decodebin name=decoder

We also have a basic media playing plugin that will take care of most things
for you. This plugin is called playbin. Try this:
<programlisting>
-gst-launch playbin uri=file:///home/joe/my-random-media-file.mpeg
+gst-launch-1.0 playbin uri=file:///home/joe/my-random-media-file.mpeg
</programlisting>
This should play the file if the format is supported, ie. you have all the
necessary demuxing and decoding and some output plugins installed.
