You access the GStreamer command line interface using the command gst-launch.
To decode an mp3 and play it through OSS, you could use
<programlisting>
gst-launch filesrc location=thesong.mp3 ! mad ! osssink
gst-launch filesrc location=thesong.mp3 ! mad ! audioconvert !
audioresample ! osssink
</programlisting>.
More examples can be found in the gst-launch man page.

To automatically detect the right codec in a pipeline, try
<programlisting>
gst-launch filesrc location=my-random-media-file.mpeg ! spider ! osssink
gst-launch filesrc location=my-random-media-file.mpeg ! decodebin !
audioconvert ! audioresample ! osssink
</programlisting>.
Try replacing osssink with sdlvideosink and see what happens.
or
<programlisting>
gst-launch filesrc location=my-random-media-file.mpeg ! decodebin !
ffmpegcolorspace ! xvimagesink
</programlisting>
Something more complicated:
<programlisting>
gst-launch filesrc location=my-random-media-file.mpeg ! decodebin name=decoder
decoder. ! ffmpegcolorspace ! xvimagesink
decoder. ! audioconvert ! audioresample ! osssink
</programlisting>

We also have a simple tool called gst-launch-ext used for debugging,
which has predefined pipelines for you. This means you can just write
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-ext (filename)
gst-launch playbin uri=file:///home/joe/my-random-media-file.mpeg
</programlisting>
and it will play the file if the extension is supported. Note that no effort
has been made for uninterrupted synchronized playback using this tool.
This should play the file if the format is supported, ie. you have all the
necessary demuxing and decoding and some output plugins installed.
