| </div> |
| <div class="refsect1"> |
| <a name="gst-plugins-base-plugins-giosrc.description"></a><h2>Description</h2> |
| <p>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'.</p> |
| <p>If an URI or <a href="/usr/share/gtk-doc/html/gioGFile.html#GFile-struct"><span class="type">GFile</span></a> is not mounted giosrc will post a message of type |
| <a href="/usr/share/gtk-doc/html/gstreamer-1.0GstMessage.html#GST-MESSAGE-ELEMENT:CAPS"><code class="literal">GST_MESSAGE_ELEMENT</code></a> with name "not-mounted" on the bus. The message |
| also contains the <a href="/usr/share/gtk-doc/html/gioGFile.html#GFile-struct"><span class="type">GFile</span></a> and the corresponding URI. |
| Applications can use the "not-mounted" message to mount the <a href="/usr/share/gtk-doc/html/gioGFile.html#GFile-struct"><span class="type">GFile</span></a> |
| by calling <a href="/usr/share/gtk-doc/html/gioGFile.html#g-file-mount-enclosing-volume"><code class="function">g_file_mount_enclosing_volume()</code></a> and then restart the |
| pipeline after the mounting has succeeded. Note that right after the |
| "not-mounted" message a normal error message is posted on the bus which |
| should be ignored if "not-mounted" is handled by the application, for |
| example by calling gst_bus_set_flushing(bus, TRUE) after the "not-mounted" |
| message was received and gst_bus_set_flushing(bus, FALSE) after the |
| mounting was successful.</p> |
