<p>
<a href="http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstBin.html"><span class="type">GstBin</span></a> that auto-magically constructs a decoding pipeline using available
decoders and demuxers via auto-plugging.
</p>
<p>
When using decodebin in your application, connect a signal handler to
<a class="link" href="gst-plugins-base-plugins-decodebin.html#GstDecodeBin-new-decoded-pad" title='The "new-decoded-pad" signal'><span class="type">"new-decoded-pad"</span></a> and connect your sinks from within the
callback function.

This element is deprecated and no longer supported. You should use the
<span class="type">uridecodebin</span> or <span class="type">decodebin2</span> element instead (or, even better: <span class="type">playbin2</span>).
