  20 <p>This function performs the last stage of three-step encoding setup, as described in the API overview under <a href="overview.html#BBR">managed bitrate modes</a>.
  21
  22 <p>Before this function is called, the <a
  23 href="../libvorbis/vorbis_info.html">vorbis_info</a> struct should be initialized
  24 by using vorbis_info_init() from the libvorbis API, one of <a
  25 href="vorbis_encode_setup_managed.html">vorbis_encode_setup_managed()</a>
  26 or <a
  27 href="vorbis_encode_setup_vbr.html">vorbis_encode_setup_vbr()</a>
  28 called to initialize the high-level encoding setup, and <a
  29 href="vorbis_encode_ctl.html">vorbis_encode_ctl()</a> called if
  30 necessary to make encoding setup changes.  vorbis_encode_setup_init()
  31 finalizes the highlevel encoding structure into a complete encoding
  32 setup after which the application may make no further setup changes.<p>
  33
  34 After encoding, vorbis_info_clear should be called.
