21 * SECTION:element-dfbvideosink
23 * DfbVideoSink renders video frames using the
24 * <ulink url="http://www.directfb.org/">DirectFB</ulink> library.
25 * Rendering can happen in two different modes :
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 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.
36 * This mode handles navigation events for every input device supported by
37 * the <ulink url="http://www.directfb.org/">DirectFB</ulink> library, it will
38 * look for available video modes in the fb.modes file and try to switch
39 * the framebuffer video mode to the most suitable one. Depending on
40 * hardware acceleration capabilities the element will handle scaling or not.
41 * If no acceleration is available it will do clipping or centering of the
42 * video frames respecting the original aspect ratio.
47 * Embedded: this mode will render video frames in a
48 * #GstDfbVideoSink:surface provided by the
49 * application developer. This is a more advanced usage of the element and
50 * it is required to integrate video playback in existing
51 * <ulink url="http://www.directfb.org/">DirectFB</ulink> applications.
54 * When using this mode the element just renders to the
55 * #GstDfbVideoSink:surface provided by the
56 * application, that means it won't handle navigation events and won't resize
57 * the #GstDfbVideoSink:surface to fit video
58 * frames geometry. Application has to implement the necessary code to grab
59 * informations about the negotiated geometry and resize there
60 * #GstDfbVideoSink:surface accordingly.
64 * For both modes the element implements a buffer pool allocation system to
65 * optimize memory allocation time and handle reverse negotiation. Indeed if
66 * you insert an element like videoscale in the pipeline the video sink will
67 * negotiate with it to try get a scaled video for either the fullscreen layout
68 * or the application provided external #GstDfbVideoSink:surface.
