Oleksij Rempel 94337d05a5 vp8enc: initiate encoder to fix a crash. 
Without this patch vp8enc send header before and after first
key frame. On second keyframe vp8dec will crash without getting
decoded frame. With this pipe it is easy to reproduce this issue:
gst-launch-1.0 videotestsrc ! vp8enc ! vp8dec ! fakesink

/**
* 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.
