| GstXvImageSink implements | |
| <a href="../html/gst-plugins-base-libs-gstnavigation.html#GstNavigation-struct">GstNavigation</a>, <a href="../html/gst-plugins-base-libs-gstvideooverlay.html#GstVideoOverlay-struct">GstVideoOverlay</a> and <a href="../html/gst-plugins-base-libs-gstcolorbalance.html#GstColorBalance-struct">GstColorBalance</a>.</p> | |
| </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. | |

| A pipeline to test hardware scaling. | |
| When the test video signal appears you can resize the window and see that | |

| be added if needed. | |

| 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). | |
