/**
* SECTION:element-vp8enc
* @see_also: vp8dec, webmmux, oggmux
*
* This element encodes raw video into a VP8 stream.
* <ulink url="http://www.webmproject.org">VP8</ulink> is a royalty-free
* video codec maintained by <ulink url="http://www.google.com/">Google
* </ulink>. It's the successor of On2 VP3, which was the base of the
* Theora video codec.
*
* To control the quality of the encoding, the #GstVP8Enc::bitrate and
* #GstVP8Enc::quality properties can be used. These two properties are
* mutualy exclusive. Setting the bitrate property will produce a constant
* bitrate (CBR) stream while setting the quality property will produce a
* variable bitrate (VBR) stream.
*
* <refsect2>
* <title>Example pipeline</title>
* |[
* gst-launch -v videotestsrc num-buffers=1000 ! vp8enc ! webmmux ! filesink location=videotestsrc.webm
* ]| This example pipeline will encode a test video source to VP8 muxed in an
* WebM container.
