/*! \page usage_encode Encoding

    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.
