| </div> |
| <div class="refsect1"> |
| <a name="gst-plugins-base-plugins-xvimagesink.description"></a><h2>Description</h2> |
| <p>XvImageSink renders video frames to a drawable (XWindow) on a local display |
| using the XVideo extension. Rendering to a remote display is theoretically |
| 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 <a href="../html/gst-plugins-base-libs-gstvideooverlay.html#GstVideoOverlay-struct"><span class="type">GstVideoOverlay</span></a> 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.</p> |
| <div class="refsect2"> |
| <a name="id-1.2.63.8.3"></a><h3>Scaling</h3> |
| <p> |
| 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 <a class="link" href="gst-plugins-base-plugins-xvimagesink.html#GstXvImageSink--force-aspect-ratio" title="The “force-aspect-ratio” property"><span class="type">“force-aspect-ratio”</span></a> |
| property it is possible to enforce scaling with a constant aspect ratio, |
| which means drawing black borders around the video frame. |
| </p> |
| </div> |
| <hr> |
| <div class="refsect2"> |
| <a name="id-1.2.63.8.4"></a><h3>Events</h3> |
| <p> |
| 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. |
| </p> |
| </div> |
| <hr> |
| <div class="refsect2"> |
| <a name="id-1.2.63.8.5"></a><h3>Pixel aspect ratio</h3> |
| <p> |
| When changing state to GST_STATE_READY, XvImageSink will open a connection to |
| the display specified in the <a class="link" href="gst-plugins-base-plugins-xvimagesink.html#GstXvImageSink--display" title="The “display” property"><span class="type">“display”</span></a> 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 |
| <a class="link" href="gst-plugins-base-plugins-xvimagesink.html#GstXvImageSink--pixel-aspect-ratio" title="The “pixel-aspect-ratio” property"><span class="type">“pixel-aspect-ratio”</span></a> property. |

| When the test video signal appears you can resize the window and see that |

| 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 |

| 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). |
