/*! \page usage_encode Encode
The vpx_codec_encode() function is at the core of the encode loop. It
processes raw images passed by the application, producing packets of
compressed data. The <code>deadline</code> parameter controls the amount
of time in microseconds the encoder should spend working on the frame. For
more information on the <code>deadline</code> parameter, see
\ref usage_deadline.
