/**
* Basic test showing how to use a direct media player component.
* <p>
* This test shows how to render the video buffer into a {@link JComponent} via a
* {@link BufferedImage} inside a {@link RenderCallbackAdapter}.
* <p>
* Some applications may like to access the native video buffer directly by
* overriding {@link DirectMediaPlayerComponent#display(com.sun.jna.Memory)} or
* providing an implementation of a {@link RenderCallback} via {@link DirectMediaPlayerComponent#onGetRenderCallback}.
* <p>
* This test also shows how to paint a lightweight overlay on top of the video.
