38  * #GstToc functions are used to create/free #GstToc and #GstTocEntry structures.
39  * Also they are used to convert #GstToc into #GstStructure and vice versa.
40  * 
41  * #GstToc lets you to inform other elements in pipeline or application that playing
42  * source has some kind of table of contents (TOC). These may be chapters, editions,
43  * angles or other types. For example: DVD chapters, Matroska chapters or cue sheet
44  * TOC. Such TOC will be useful for applications to display instead of just a
45  * playlist.
46  * 
47  * Using TOC is very easy. Firstly, create #GstToc structure which represents root
48  * contents of the source. You can also attach TOC-specific tags to it. Then fill
49  * it with #GstTocEntry entries by appending them to the #GstToc using
50  * gst_toc_append_entry(), and appending subentries to a #GstTocEntry using
51  * gst_toc_entry_append_sub_entry().
52  * 
53  * Note that root level of the TOC can contain only either editions or chapters. You
54  * should not mix them together at the same level. Otherwise you will get serialization
55  * /deserialization errors. Make sure that no one of the entries has negative start and
56  * stop values.
57  * 
58  * Use gst_event_new_toc() to create a new TOC #GstEvent, and gst_event_parse_toc() to
59  * parse received TOC event. Use gst_event_new_toc_select() to create a new TOC select #GstEvent,
60  * and gst_event_parse_toc_select() to parse received TOC select event. The same rule for
61  * the #GstMessage: gst_message_new_toc() to create new TOC #GstMessage, and
62  * gst_message_parse_toc() to parse received TOC message.
63  * 
64  * TOCs can have global scope or current scope. Global scope TOCs contain
65  * all entries that can possibly be selected using a toc select event, and
66  * are what an application is usually interested in. TOCs with current scope
67  * only contain the parts of the TOC relevant to the currently selected/playing
68  * stream; the current scope TOC is used by downstream elements such as muxers
69  * to write correct TOC entries when transcoding files, for example. When
70  * playing a DVD, the global TOC would contain a hierarchy of all titles,
71  * chapters and angles, for example, while the current TOC would only contain
72  * the chapters for the currently playing title if playback of a specific
73  * title was requested.
74  * 
75  * Applications and plugins should not rely on TOCs having a certain kind of
76  * structure, but should allow for different alternatives. For example, a
77  * simple CUE sheet embedded in a file may be presented as a flat list of
78  * track entries, or could have a top-level edition node (or some other
79  * alternative type entry) with track entries underneath that node; or even
80  * multiple top-level edition nodes (or some other alternative type entries)
81  * each with track entries underneath, in case the source file has extracted
82  * a track listing from different sources).
