Description</h1>
<p>gstreamermm provides C++ bindings for the <a href="http://gstreamer.freedesktop.org">GStreamer streaming multimedia library</a>. With gstreamermm it is possible to develop applications that work with multimedia in C++. For instance, see <a class="el" href="classGst_1_1Element.html" title="Abstract base class for all pipeline elements. ">Gst::Element</a>, <a class="el" href="classGst_1_1Bin.html" title="Base class and element that can contain other elements. ">Gst::Bin</a> and <a class="el" href="classGst_1_1Pipeline.html" title="A top-level bin with clocking and bus management functionality. ">Gst::Pipeline</a>.</p>
<h1><a class="anchor" id="Features"></a>
Features</h1>
<ul>
<li>gstreamermm is developed over <a href="http://www.gtkmm.org/index.shtml">glibmm</a>, <a href="http://libsigc.sourceforge.net/">libsigc++</a> and <a href="http://libxmlplusplus.sourceforge.net/">libxml++</a> and the functionalities they provide.</li>
<li>Referencing and unreferencing of GObjects is handled automatically via glibmm's automatic pointer class, Glib::RefPtr.</li>
<li>libsigc++'s slots are used for callbacks and signals.</li>
<li>Most of the GStreamer core and base plug-ins are wrapped.</li>
</ul>
<h1><a class="anchor" id="Basics"></a>
Basic Usage</h1>
<p>Some form of the <a class="el" href="namespaceGst.html#a4368f0336db20f7dae336c97ebce0ef1" title="Initializes gstreamermm parsing command line arguments. ">Gst::init()</a> method must be called before using the library's classes, functions, etc. To get a deeper understanding of how to set up pipelines, deal with elements, pads, etc., see the <a href="http://gstreamer.freedesktop.org/data/doc/gstreamer/head/manual/html/index.html">GStreamer Application Development Manual</a>.</p>
<p>The following includes the gstreamermm header: </p><div class="fragment"><div class="line"><span class="preprocessor">#include <gstreamermm.h></span></div></div><!-- fragment --><p> (You may include individual headers, such as <code>gstreamermm/pipeline.h</code> instead.)</p>
<h1><a class="anchor" id="Compiling"></a>
Compiling</h1>
<p>If your source file is <code>program.cc</code>, you can compile it with: </p><div class="fragment"><div class="line">g++ program.cc -o program `pkg-config --cflags --libs gstreamermm-1.0`</div></div><!-- fragment --><p>Alternatively, if using autoconf, use the following in <code>configure.ac:</code> </p><div class="fragment"><div class="line">PKG_CHECK_MODULES([GSTREAMERMM_1_0], [gstreamermm-1.0])</div></div><!-- fragment --><p> Then use the generated <code>GSTREAMERMM_1_0_CFLAGS</code> and <code>GSTREAMERMM_1_0_LIBS</code> variables in the project <code>Makefile.am</code> files. For example: </p><div class="fragment"><div class="line">program_CPPFLAGS = $(GSTREAMERMM_1_0_CFLAGS)</div><div class="line">program_LDADD = $(GSTREAMERMM_1_0_LIBS)</div></div><!-- fragment --> </div></div><!-- contents -->
