/**
* SECTION:gsttocsetter
+ * @title: GstTocSetter
* @short_description: Element interface that allows setting and retrieval
* of the TOC
*
*
* Elements that support some kind of chapters or editions (or tracks like in
* the FLAC cue sheet) will implement this interface.
- *
+ *
* If you just want to retrieve the TOC in your application then all you
* need to do is watch for TOC messages on your pipeline's bus (or you can
* perform TOC query). This interface is only for setting TOC data, not for
* extracting it. To set TOC from the application, find proper tocsetter element
* and set TOC using gst_toc_setter_set_toc().
- *
+ *
* Elements implementing the #GstTocSetter interface can extend existing TOC
* by getting extend UID for that (you can use gst_toc_find_entry() to retrieve it)
* with any TOC entries received from downstream.
