<a name="gst-plugins-base-plugins-appsink.description"></a><h2>Description</h2>
<p>
Appsink is a sink plugin that supports many different methods for making
the application get a handle on the GStreamer data in a pipeline. Unlike
most GStreamer elements, Appsink provides external API functions.
</p>
<p>
For the documentation of the API, please see the
<a href="http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-libs/html/gst-plugins-base-libs-appsink.html">libgstapp</a> section in
the GStreamer Plugins Base Libraries documentation.
