+ * <ulink url="http://www.webmproject.org">VP9</ulink> is a royalty-free

+ * To control the quality of the encoding, the #GstVP9Enc::target-bitrate,
+ * #GstVP9Enc::min-quantizer, #GstVP9Enc::max-quantizer or #GstVP9Enc::cq-level
+ * properties can be used. Which one is used depends on the mode selected by
+ * the #GstVP9Enc::end-usage property.

+ * for explanation, examples for useful encoding parameters and more details
