The ovectl_ratemanage2_arg structure is used with <a
href="vorbis_encode_ctl.html">vorbis_encode_ctl()</a> and the OV_ECTL_RATEMANAGE2_GET and
OV_ECTL_RATEMANAGE2_SET calls in order to query and modify specifics
of the encoder's bitrate management configuration.

<h3>Relevant Struct Members</h3>
<dl>
<dt><i>management_active</i></dt>
<dd>nonzero if bitrate management is active</dd>
<dt><i>bitrate_limit_min_kbps</i></dt>
<dd>Lower allowed bitrate limit in kilobits per second</dd>
<dt><i>bitrate_limit_max_kbps</i></dt>
<dd>Upper allowed bitrate limit in kilobits per second</dd>
<dt><i>bitrate_limit_reservoir_bits</i></dt>
<dd>Size of the bitrate reservoir in bits</dd>
<dt><i>bitrate_limit_reservoir_bias</i></dt>
<dd>Regulates the bitrate reservoir's preferred fill level in a range
from 0.0 to 1.0; 0.0 tries to bank bits to buffer against future
bitrate spikes, 1.0 buffers against future sudden drops in
instantaneous bitrate. Default is 0.1 </dd>
<dt><i>bitrate_average_kbps</i></dt>
<dd>Average bitrate setting in kilobits per second</dd>
<dt><i>bitrate_average_damping</i></dt> <dd>Slew rate limit setting
for average bitrate adjustment; sets the minimum time in seconds the
bitrate tracker may swing from one extreme to the other when boosting
or damping average bitrate.</dd>
