/**
* 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::target-bitrate,
* #GstVP8Enc::min-quantizer, #GstVP8Enc::max-quantizer or #GstVP8Enc::cq-level
* properties can be used. Which one is used depends on the mode selected by
* the #GstVP8Enc::end-usage property.
* See <ulink url="http://www.webmproject.org/docs/encoder-parameters/">Encoder Parameters</ulink>
* for explanation, examples for useful encoding parameters and more details
* on the encoding parameters.
*
* <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.
