+ * SECTION:element-videoscale
+ * @title: videoscale
+ * @see_also: videorate, videoconvert
+ *
+ * This element resizes video frames. By default the element will try to
+ * negotiate to the same size on the source and sinkpad so that no scaling
+ * is needed. It is therefore safe to insert this element in a pipeline to
+ * get more robust behaviour without any cost if no scaling is needed.
+ *
+ * This element supports a wide range of color spaces including various YUV and
+ * RGB formats and is therefore generally able to operate anywhere in a
+ * pipeline.
+ *
+ * ## Example pipelines
+ * |[
+ * gst-launch-1.0 -v filesrc location=videotestsrc.ogg ! oggdemux ! theoradec ! videoconvert ! videoscale ! autovideosink
+ * ]|
+ * Decode an Ogg/Theora and display the video. If the video sink chosen
+ * cannot perform scaling, the video scaling will be performed by videoscale
+ * when you resize the video window.
+ * To create the test Ogg/Theora file refer to the documentation of theoraenc.
+ * |[
+ * gst-launch-1.0 -v filesrc location=videotestsrc.ogg ! oggdemux ! theoradec ! videoconvert ! videoscale ! video/x-raw,width=100 ! autovideosink
