Element interface that allows setting 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
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.
void gst_toc_setter_set_toc (
Set the given TOC on the setter. Previously set TOC will be unreffed before setting a new one.
GstToc * gst_toc_setter_get_toc (
Return current TOC the setter uses. The TOC should not be modified without making it writable first.
