+=== Using OpenGL with SDL ===
+
+PJSIP supports OpenGL video rendering with SDL. Follow these steps to enable and use the OpenGL backend.
+
+ 1. Install OpenGL development libraries for your system. The instructions vary, and some platforms may have OpenGL development libraries installed by default.
+   - For Ubuntu 12.04, you can run the following:
+     {{{
+$ sudo apt-get install freeglut3 freeglut3-dev
+$ sudo apt-get install binutils-gold
+     }}}
+ 1. Enable OpenGL support in SDL. With GNU tools, OpenGL support will be detected automatically by the "configure" script. Make sure that the "configure" output shows that OpenGL has been detected, by looking for line like this in the output:
+    {{{
+checking for OpenGL (GLX) support... yes
+    }}}
+ 1. Enable SDL OpenGL support in PJSIP, by declaring this in your {{{config_site.h}}}:
+    {{{
+#define PJMEDIA_VIDEO_DEV_SDL_HAS_OPENGL        1
+    }}}
+ 1. If you're not using Visual Studio, add OpenGL library in your application's input library list. If you're using GNU tools, you can add this in '''{{{user.mak}}}''' file in root PJSIP directory:
+    {{{
+export LDFLAGS += -lGL
+    }}}
+ 1. Rebuild PJSIP
+ 1. Now '''"SDL openGL renderer"''' device should show up in video device list. Simply just use this device.
