22 * SECTION:element-xvimagesink
24 * XvImageSink renders video frames to a drawable (XWindow) on a local display
25 * using the XVideo extension. Rendering to a remote display is theoretically
26 * possible but i doubt that the XVideo extension is actually available when
27 * connecting to a remote display. This element can receive a Window ID from the
28 * application through the #GstVideoOverlay interface and will then render
29 * video frames in this drawable. If no Window ID was provided by the
30 * application, the element will create its own internal window and render
34 * <title>Scaling</title>
36 * The XVideo extension, when it's available, handles hardware accelerated
37 * scaling of video frames. This means that the element will just accept
38 * incoming video frames no matter their geometry and will then put them to the
39 * drawable scaling them on the fly. Using the #GstXvImageSink:force-aspect-ratio
40 * property it is possible to enforce scaling with a constant aspect ratio,
41 * which means drawing black borders around the video frame.
45 * <title>Events</title>
47 * XvImageSink creates a thread to handle events coming from the drawable. There
48 * are several kind of events that can be grouped in 2 big categories: input
49 * events and window state related events. Input events will be translated to
50 * navigation events and pushed upstream for other elements to react on them.
51 * This includes events such as pointer moves, key press/release, clicks etc...
52 * Other events are used to handle the drawable appearance even when the data
53 * is not flowing (GST_STATE_PAUSED). That means that even when the element is
54 * paused, it will receive expose events from the drawable and draw the latest
55 * frame with correct borders/aspect-ratio.
59 * <title>Pixel aspect ratio</title>
61 * When changing state to GST_STATE_READY, XvImageSink will open a connection to
62 * the display specified in the #GstXvImageSink:display property or the
63 * default display if nothing specified. Once this connection is open it will
64 * inspect the display configuration including the physical display geometry and
65 * then calculate the pixel aspect ratio. When receiving video frames with a
66 * different pixel aspect ratio, XvImageSink will use hardware scaling to
67 * display the video frames correctly on display's pixel aspect ratio.
68 * Sometimes the calculated pixel aspect ratio can be wrong, it is
69 * then possible to enforce a specific pixel aspect ratio using the
70 * #GstXvImageSink:pixel-aspect-ratio property.
74 * <title>Examples</title>
76 * gst-launch -v videotestsrc ! xvimagesink
77 * ]| A pipeline to test hardware scaling.
78 * When the test video signal appears you can resize the window and see that
79 * video frames are scaled through hardware (no extra CPU cost).
81 * gst-launch -v videotestsrc ! xvimagesink force-aspect-ratio=true
82 * ]| Same pipeline with #GstXvImageSink:force-aspect-ratio property set to true
83 * You can observe the borders drawn around the scaled image respecting aspect
86 * gst-launch -v videotestsrc ! navigationtest ! xvimagesink
87 * ]| A pipeline to test navigation events.
88 * While moving the mouse pointer over the test signal you will see a black box
89 * following the mouse pointer. If you press the mouse button somewhere on the
90 * video and release it somewhere else a green box will appear where you pressed
91 * the button and a red one where you released it. (The navigationtest element
92 * is part of gst-plugins-good.) You can observe here that even if the images
93 * are scaled through hardware the pointer coordinates are converted back to the
94 * original video frame geometry so that the box can be drawn to the correct
95 * position. This also handles borders correctly, limiting coordinates to the
98 * gst-launch -v videotestsrc ! video/x-raw, pixel-aspect-ratio=(fraction)4/3 ! xvimagesink
99 * ]| This is faking a 4/3 pixel aspect ratio caps on video frames produced by
100 * videotestsrc, in most cases the pixel aspect ratio of the display will be
101 * 1/1. This means that XvImageSink will have to do the scaling to convert
102 * incoming frames to a size that will match the display pixel aspect ratio
103 * (from 320x240 to 320x180 in this case). Note that you might have to escape
104 * some characters for your shell like '\(fraction\)'.
106 * gst-launch -v videotestsrc ! xvimagesink hue=100 saturation=-100 brightness=100
107 * ]| Demonstrates how to use the colorbalance interface.
