23 * @title: dfbvideosink
24 *
25 * DfbVideoSink renders video frames using the
26 * <ulink url="http://www.directfb.org/">DirectFB</ulink> library.
27 * Rendering can happen in two different modes :
28 *
29 * * Standalone: this mode will take complete control of the monitor forcing
30 * <ulink url="http://www.directfb.org/">DirectFB</ulink> to fullscreen layout.
31 * This is convenient to test using the gst-launch-1.0 command line tool or
32 * other simple applications. It is possible to interrupt playback while
33 * being in this mode by pressing the Escape key.
34 * This mode handles navigation events for every input device supported by
35 * the <ulink url="http://www.directfb.org/">DirectFB</ulink> library, it will
36 * look for available video modes in the fb.modes file and try to switch
37 * the framebuffer video mode to the most suitable one. Depending on
38 * hardware acceleration capabilities the element will handle scaling or not.
39 * If no acceleration is available it will do clipping or centering of the
40 * video frames respecting the original aspect ratio.
41 *
42 * * Embedded: this mode will render video frames in a
43 * #GstDfbVideoSink:surface provided by the
44 * application developer. This is a more advanced usage of the element and
45 * it is required to integrate video playback in existing
46 * <ulink url="http://www.directfb.org/">DirectFB</ulink> applications.
47 * When using this mode the element just renders to the
48 * #GstDfbVideoSink:surface provided by the
49 * application, that means it won't handle navigation events and won't resize
50 * the #GstDfbVideoSink:surface to fit video
51 * frames geometry. Application has to implement the necessary code to grab
52 * informations about the negotiated geometry and resize there
53 * #GstDfbVideoSink:surface accordingly.
54 *
55 * For both modes the element implements a buffer pool allocation system to
56 * optimize memory allocation time and handle reverse negotiation. Indeed if
57 * you insert an element like videoscale in the pipeline the video sink will
58 * negotiate with it to try get a scaled video for either the fullscreen layout
59 * or the application provided external #GstDfbVideoSink:surface.
60 *
61 * ## Example application
62 *
63 * <include xmlns="http://www.w3.org/2003/XInclude" href="element-dfb-example.xml" />
64 *
65 * ## Example pipelines
