/**
* SECTION:element-vah265enc
* @title: vah265enc
* @short_description: A VA-API based H265 video encoder
*
* vah265enc encodes raw video VA surfaces into H.265 bitstreams using
* the installed and chosen [VA-API](https://01.org/linuxmedia/vaapi)
* driver.
*
* The raw video frames in main memory can be imported into VA surfaces.
*
* ## Example launch line
* ```
* gst-launch-1.0 videotestsrc num-buffers=60 ! timeoverlay ! vah265enc ! h265parse ! mp4mux ! filesink location=test.mp4
* ```
*
* Since: 1.22
