This method allows you to create a pipeline from a command
line syntax description. The following example creates a simple
mp3 player.
<programlisting>
GstElement *pipeline;
/* create a pipeline to hold our elements */
pipeline = gst_pipeline_new ("launch");
/* build a pipeline in the pipeline */
gst_parse_launch ("disksrc location=some.mp3 ! mad ! osssink", GST_BIN (pipeline));
/* play the thing */
gst_element_set_state (pipeline, GST_STATE_PLAYING);
while (gst_bin_iterate (GST_BIN (pipeline)));
gst_element_set_state (pipeline, GST_STATE_NULL);
</programlisting>
</para>
<para>
Elements are separated with a <option>!</option>, properties are set with
<replaceable>property</replaceable>=<replaceable>value</replaceable>, specific pads
of an element are selected by replacing the <option>!</option> with
<replaceable>padname</replaceable><option>!</option>.
