+ * video frames are scaled through hardware (no extra CPU cost). By default

+ * ]| Same pipeline with #GstXvImageSink:force-aspect-ratio property set to
+ * false. You can observe that no borders are drawn around the scaled image

+ * gst-launch-1.0 -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
* 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). Note that you might have to escape
- * some characters for your shell like '\(fraction\)'.
