23 * @title: dfbvideosink
25 * DfbVideoSink renders video frames using the
26 * [DirectFB](http://www.directfb.org/) library.
27 * Rendering can happen in two different modes :
29 * * Standalone: this mode will take complete control of the monitor forcing
30 * DirectFB to fullscreen layout.
32 * This is convenient to test using the gst-launch-1.0 command line tool or
33 * other simple applications. It is possible to interrupt playback while
34 * being in this mode by pressing the Escape key.
35 * This mode handles navigation events for every input device supported by
36 * the DirectFB library, it will look for available video modes in the fb.modes
37 * file and try to switch the framebuffer video mode to the most suitable one.
38 * Depending on hardware acceleration capabilities the element will handle
41 * If no acceleration is available it will do clipping or centering of the
42 * video frames respecting the original aspect ratio.
44 * * Embedded: this mode will render video frames in a
45 * #GstDfbVideoSink:surface provided by the
46 * application developer. This is a more advanced usage of the element and
47 * it is required to integrate video playback in existing
48 * DirectFB applications.
50 * When using this mode the element just renders to the
51 * #GstDfbVideoSink:surface provided by the
52 * application, that means it won't handle navigation events and won't resize
53 * the #GstDfbVideoSink:surface to fit video
54 * frames geometry. Application has to implement the necessary code to grab
55 * information about the negotiated geometry and resize there
56 * #GstDfbVideoSink:surface accordingly.
58 * For both modes the element implements a buffer pool allocation system to
59 * optimize memory allocation time and handle reverse negotiation. Indeed if
60 * you insert an element like videoscale in the pipeline the video sink will
61 * negotiate with it to try get a scaled video for either the fullscreen layout
62 * or the application provided external #GstDfbVideoSink:surface.
