+ * @short_description: A VA-API based AV1 video decoder
+ *
+ * vaav1dec decodes AV1 bitstreams to VA surfaces using the
+ * installed and chosen [VA-API](https://01.org/linuxmedia/vaapi)
+ * driver.
+ *
+ * The decoding surfaces can be mapped onto main memory as video
+ * frames.
+ *
+ * ## Example launch line
+ * ```
+ * gst-launch-1.0 filesrc location=sample.av1 ! ivfparse ! av1parse ! vaav1dec ! autovideosink
+ * ```
+ *
+ * Since: 1.20
