+ * SECTION:element-gnomevfssrc
+ * @see_also: #GstFileSrc, #GstGnomeVFSSink
+ *
+ * This plugin reads data from a local or remote location specified
+ * by an URI. This location can be specified using any protocol supported by
+ * the GnomeVFS library. Common protocols are 'file', 'http', 'ftp', or 'smb'.
+ *
+ * In case the #GstGnomeVFSSrc:iradio-mode property is set and the
+ * location is a http resource, gnomevfssrc will send special icecast http
+ * headers to the server to request additional icecast metainformation. If
+ * the server is not an icecast server, it will display the same behaviour
+ * as if the #GstGnomeVFSSrc:iradio-mode property was not set. However,
+ * if the server is in fact an icecast server, gnomevfssrc will output
+ * data with a media type of application/x-icy, in which case you will
+ * need to use the #GstICYDemux element as follow-up element to extract
+ * the icecast meta data and to determine the underlying media type.
+ *
+ * <refsect2>
+ * <title>Example launch lines</title>
+ * |[
+ * gst-launch -v gnomevfssrc location=file:///home/joe/foo.xyz ! fakesink
+ * ]| The above pipeline will simply read a local file and do nothing with the
+ * data read. Instead of gnomevfssrc, we could just as well have used the
+ * filesrc element here.
+ * |[
+ * gst-launch -v gnomevfssrc location=smb://othercomputer/foo.xyz ! filesink location=/home/joe/foo.xyz
+ * ]| The above pipeline will copy a file from a remote host to the local file
+ * system using the Samba protocol.
+ * |[
+ * gst-launch -v gnomevfssrc location=http://music.foobar.com/demo.mp3 ! mad ! audioconvert ! audioresample ! alsasink
+ * ]| The above pipeline will read and decode and play an mp3 file from a
+ * web server using the http protocol.
