<para>
|
|
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 ("filesrc 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);
|
|

<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>.
|
|
</para>
|

<para>
|
|
Elements can be added to a bin by embracing them with <option>()</option>. Threads
|
|
can be made with <option>{}</option>.
