* SECTION:element-ximagesink

* <refsect2>
|
||||
* <para>
|
||||
* XImageSink renders video frames to a drawable (XWindow) on a local or remote
|
||||
* display. This element can receive a Window ID from the application through
|
||||
* the XOverlay interface and will then render video frames in this drawable.
|
||||
* If no Window ID was provided by the application, the element will create its
|
||||
* own internal window and render into it.
|
||||
* </para>
|
||||
* <title>Scaling</title>
|
||||
* <para>
|
||||
* As standard XImage rendering to a drawable is not scaled, XImageSink will use
|
||||
* reverse caps negotiation to try to get scaled video frames for the drawable.
|
||||
* This is accomplished by asking the peer pad if it accepts some different caps
|
||||
* which in most cases implies that there is a scaling element in the pipeline,
|
||||
* or that an element generating the video frames can generate them with a
|
||||
* different geometry. This mechanism is handled during buffer allocations, for
|
||||
* each allocation request the video sink will check the drawable geometry, look
|
||||
* at the
|
||||
* <link linkend="GstXImageSink--force-aspect-ratio">force-aspect-ratio</link>
|
||||
* property, calculate the geometry of desired video frames and then check that
|
||||
* the peer pad accept those new caps. If it does it will then allocate a buffer
|
||||
* in video memory with this new geometry and return it with the new caps.
|
||||
* </para>
|
||||
* <title>Events</title>
|
||||
* <para>
|
||||
* XImageSink creates a thread to handle events coming from the drawable. There
|
||||
* are several kind of events that can be grouped in 2 big categories: input
|
||||
* events and window state related events. Input events will be translated to
|
||||
* navigation events and pushed upstream for other elements to react on them.
|
||||
* This includes events such as pointer moves, key press/release, clicks etc...
|
||||
* Other events are used to handle the drawable appearance even when the data
|
||||
* is not flowing (GST_STATE_PAUSED). That means that even when the element is
|
||||
* paused, it will receive expose events from the drawable and draw the latest
|
||||
* frame with correct borders/aspect-ratio.
|
||||
* </para>
|
||||
* <title>Pixel aspect ratio</title>
|
||||
* <para>
|
||||
* When changing state to GST_STATE_READY, XImageSink will open a connection to
|
||||
* the display specified in the
|
||||
* <link linkend="GstXImageSink--display">display</link> property or the default
|
||||
* display if nothing specified. Once this connection is open it will inspect
|
||||
* the display configuration including the physical display geometry and
|
||||
* then calculate the pixel aspect ratio. When caps negotiation will occur, the
|
||||
* video sink will set the calculated pixel aspect ratio on the caps to make
|
||||
* sure that incoming video frames will have the correct pixel aspect ratio for
|
||||
* this display. Sometimes the calculated pixel aspect ratio can be wrong, it is
|
||||
* then possible to enforce a specific pixel aspect ratio using the
|
||||
* <link linkend="GstXImageSink--pixel-aspect-ratio">pixel-aspect-ratio</link>
|
||||
* property.
|
||||
* </para>
|
||||
* <title>Examples</title>
|
||||
* <para>
|
||||
* Here is a simple pipeline to test reverse negotiation :
|
||||
* <programlisting>
|
||||
* gst-launch -v videotestsrc ! queue ! ximagesink
|
||||
* </programlisting>
|
||||
* When the test video signal appears you can resize the window and see that
|
||||
* scaled buffers of the desired size are going to arrive with a short delay.
|
||||
* This illustrates how buffers of desired size are allocated along the way.
|
||||
* If you take away the queue, scaling will happen almost immediately.
|
||||
* </para>
|
||||
* <para>
|
||||
* Here is a simple pipeline to test navigation events :
|
||||
* <programlisting>
|
||||
* gst-launch -v videotestsrc ! navigationtest ! ffmpegcolorspace ! ximagesink
|
||||
* </programlisting>
|
||||
* While moving the mouse pointer over the test signal you will see a black box
|
||||
* following the mouse pointer. If you press the mouse button somewhere on the
|
||||
* video and release it somewhere else a green box will appear where you pressed
|
||||
* the button and a red one where you released it. (The navigationtest element
|
||||
* is part of gst-plugins-good.)
|
||||
* </para>
|
||||
* <para>
|
||||
* Here is a simple pipeline to test pixel aspect ratio :
|
||||
* <programlisting>
|
||||
* gst-launch -v videotestsrc ! video/x-raw-rgb, pixel-aspect-ratio=(fraction)4/3 ! videoscale ! ximagesink
|
||||
* </programlisting>
|
||||
* This is faking a 4/3 pixel aspect ratio caps on video frames produced by
|
||||
* videotestsrc, in most cases the pixel aspect ratio of the display will be
|
||||
* 1/1. This means that videoscale will have to do the scaling to convert
|
||||
* incoming frames to a size that will match the display pixel aspect ratio
|
||||
* (from 320x240 to 320x180 in this case). Note that you might have to escape
|
||||
* some characters for your shell like '\(fraction\)'.
|
||||
* </para>
