It is possible to interrupt playback while * being in this mode by pressing the Escape key. * This mode handles navigation events for every input device supported by * the DirectFB library, it will * look for available video modes in the fb.modes file and try to switch * the framebuffer video mode to the most suitable one. Depending on * hardware acceleration capabilities the element will handle scaling or not. * If no acceleration is available it will do clipping or centering of the * video frames respecting the original aspect ratio. * * * Embedded: this mode will render video frames in a * #GstDfbVideoSink:surface provided by the * application developer. This is a more advanced usage of the element and * it is required to integrate video playback in existing * DirectFB applications. * When using this mode the element just renders to the * #GstDfbVideoSink:surface provided by the * application, that means it won't handle navigation events and won't resize * the #GstDfbVideoSink:surface to fit video * frames geometry. Application has to implement the necessary code to grab * informations about the negotiated geometry and resize there * #GstDfbVideoSink:surface accordingly. * * For both modes the element implements a buffer pool allocation system to * optimize memory allocation time and handle reverse negotiation. Indeed if * you insert an element like videoscale in the pipeline the video sink will * negotiate with it to try get a scaled video for either the fullscreen layout * or the application provided external #GstDfbVideoSink:surface. * * ## Example application * * * * ## Example pipelines * |[ * gst-launch-1.0 -v videotestsrc ! dfbvideosink hue=20000 saturation=40000 brightness=25000 * ]| test the colorbalance interface implementation in dfbvideosink */ #ifdef HAVE_CONFIG_H #include "config.h" #endif #include /* Object header */ #include "dfbvideosink.h" #include #include /* Debugging category */ GST_DEBUG_CATEGORY_STATIC (dfbvideosink_debug);
