/**

* SECTION:element-dfbvideosink
|
|
* @title: dfbvideosink
|
|
*
|
|
* DfbVideoSink renders video frames using the
|
|
* [DirectFB](http://www.directfb.org/) library.
|
|
* Rendering can happen in two different modes :
|
|
*
|
|
* * Standalone: this mode will take complete control of the monitor forcing
|
|
* DirectFB to fullscreen layout.
|
|
*
|
|
* This is convenient to test using the gst-launch-1.0 command line tool or
|
|
* other simple applications. 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
|
|
* information 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
|
|
*
|
|
* <include xmlns="http://www.w3.org/2003/XInclude" href="element-dfb-example.xml" />
|
|
*
|
|
* ## Example pipelines
|
|
* |[
|
|
* gst-launch-1.0 -v videotestsrc ! dfbvideosink hue=20000 saturation=40000 brightness=25000
|
|
* ]| test the colorbalance interface implementation in dfbvideosink
