Rendering to a remote display is theorically - * possible but i doubt that the XVideo extension is actually available when - * connecting to a 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. - * - * <refsect2> - * <title>Scaling</title> - * <para> - * The XVideo extension, when it's available, handles hardware accelerated - * scaling of video frames. This means that the element will just accept - * incoming video frames no matter their geometry and will then put them to the - * drawable scaling them on the fly. Using the #GstXvImageSink:force-aspect-ratio - * property it is possible to enforce scaling with a constant aspect ratio, - * which means drawing black borders around the video frame. - * </para> - * </refsect2> - * <refsect2> - * <title>Events</title> - * <para> - * XvImageSink 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> - * </refsect2> - * <refsect2> - * <title>Pixel aspect ratio</title> - * <para> - * When changing state to GST_STATE_READY, XvImageSink will open a connection to - * the display specified in the #GstXvImageSink:display 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 receiving video frames with a - * different pixel aspect ratio, XvImageSink will use hardware scaling to - * display the video frames correctly on display's pixel aspect ratio. - * Sometimes the calculated pixel aspect ratio can be wrong, it is - * then possible to enforce a specific pixel aspect ratio using the - * #GstXvImageSink:pixel-aspect-ratio property. - * </para> - * </refsect2> - * <refsect2> - * <title>Examples</title> - * |[ - * gst-launch -v videotestsrc ! xvimagesink - * ]| A pipeline to test hardware scaling. - * When the test video signal appears you can resize the window and see that - * video frames are scaled through hardware (no extra CPU cost). - * |[ - * gst-launch -v videotestsrc ! xvimagesink force-aspect-ratio=true - * ]| Same pipeline with #GstXvImageSink:force-aspect-ratio property set to true - * You can observe the borders drawn around the scaled image respecting aspect - * ratio. - * |[ - * gst-launch -v videotestsrc ! navigationtest ! xvimagesink - * ]| A pipeline to test navigation events. - * 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.) You can observe here that even if the images - * are scaled through hardware the pointer coordinates are converted back to the - * original video frame geometry so that the box can be drawn to the correct - * position. This also handles borders correctly, limiting coordinates to the - * image area - * |[ - * gst-launch -v videotestsrc ! video/x-raw-yuv, pixel-aspect-ratio=(fraction)4/3 ! xvimagesink - * ]| 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 XvImageSink 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).
