| Element interface that allows setting of the TOC. |
| </p> |
| <p> |
| Elements that support some kind of chapters or editions (or tracks like in |
| the FLAC cue sheet) will implement this interface. |
| </p> |
| <p> |
| 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 <a class="link" href="gstreamer-GstTocSetter.html#gst-toc-setter-set-toc" title="gst_toc_setter_set_toc ()"><code class="function">gst_toc_setter_set_toc()</code></a>. |
| </p> |
| <p> |
| Elements implementing the <a class="link" href="gstreamer-GstTocSetter.html#GstTocSetter" title="GstTocSetter"><span class="type">GstTocSetter</span></a> interface can extend existing TOC |
| by getting extend UID for that (you can use <a class="link" href="gstreamer-GstToc.html#gst-toc-find-entry" title="gst_toc_find_entry ()"><code class="function">gst_toc_find_entry()</code></a> to retrieve it) |
| with any TOC entries received from downstream. |
