/**
* SECTION:element-vaav1dec
* @title: vaav1dec
* @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
