- * SECTION:element-giosrc
- * @short_description: Read from any GIO-supported location
- * @see_also: #GstFileSrc, #GstGnomeVFSSrc, #GstGioSink
- *
- * <refsect2>
- * <para>
- * 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 GIO library or it's VFS backends. Common protocols are 'file', 'http',
- * 'ftp', or 'smb'.
- * </para>
- * <para>
- * Example pipeline:
- * <programlisting>
- * gst-launch -v giosrc location=file:///home/joe/foo.xyz ! fakesink
- * </programlisting>
- * The above pipeline will simply read a local file and do nothing with the
- * data read. Instead of giosrc, we could just as well have used the
- * filesrc element here.
- * </para>
- * <para>
- * Another example pipeline:
- * <programlisting>
- * gst-launch -v giosrc location=smb://othercomputer/foo.xyz ! filesink location=/home/joe/foo.xyz
- * </programlisting>
- * The above pipeline will copy a file from a remote host to the local file
- * system using the Samba protocol.
- * </para>
- * <para>
- * Yet another example pipeline:
- * <programlisting>
- * gst-launch -v giosrc location=http://music.foobar.com/demo.mp3 ! mad ! audioconvert ! audioresample ! alsasink
- * </programlisting>
- * The above pipeline will read and decode and play an mp3 file from a
- * web server using the http protocol.
- * </para>
- * </refsect2>

-/* FIXME: We would like to mount the enclosing volume of an URL
- * if it isn't mounted yet but this is possible async-only.
- * Unfortunately this requires a running main loop from the
- * default context and we can't guarantuee this!
- *
- * We would also like to do authentication while mounting.
