+- gtkvideooverlay:
+Show how to use the videooverlay interface through GTK.
+It's possible to switch bettween GST_STATE through four buttons.
+
+-filternovideooverlay:
+A more complex pipeline is switched bettween the GST states
+without using the videooverlay interface.

+-fxtest:
+switch bettween effects of the gleffects filter.
+
+-pixbufdrop:
+drag and drop a png file and overlay it using alpha channel.
+It uses gloverlay filter.
+
+-switchvideooverlay:
+change the videooverlay window while the stream is playing.

+This example illustrates how to integrate Gstreamer GL plugin with
+Qt. In particular it uses glupload with fakesink elements to create
+texture with decoded video frame. This texture is shared with
+QGLWidget derived class, which paints a cube with video texture on
+each face.
+
+To compile the example, include and library paths might be adjusted in
+.pro file according to your installation of the gstreamer and
+corresponding development files. Most probably, the adjustments will
+be necessary on Windows.
+
+To run the example simply start executable file after compilation. If
+there is no command line arguments provided, then videotestsrc element
+will be used to generate video. The following pipeline will be created
+in this case:
+
+videotestsrc ! video/x-raw, width=640, height=480, framerate=(fraction)30/1 ! glupload ! fakesink sync=1
+
+It is also possible to provide the video file name as a first command
+line parameter, i.e. ./qglwtextureshare myvideo.ogv . In this case,
+the following pipeline will be executed:
+
+filesrc location=myvideo.ogv ! decodebin2 ! glupload ! fakesink sync=1
+
+I would appreciate any feedback and improvement suggestions for this
+example.
+
+Have fun :-)
