@section wavpack
WavPack lossless audio encoder.
This is a libavcodec-native WavPack encoder. There is also an encoder based on
libwavpack, but there is virtually no reason to use that encoder.
See also @ref{libwavpack}.
@subsection Options
The equivalent options for @command{wavpack} command line utility are listed in
parentheses.
@subsubsection Shared options
The following shared options are effective for this encoder. Only special notes
about this particular encoder will be documented here. For the general meaning
of the options, see @ref{codec-options,,the Codec Options chapter}.
@table @option
@item frame_size (@emph{--blocksize})
For this encoder, the range for this option is between 128 and 131072. Default
is automatically decided based on sample rate and number of channel.
For the complete formula of calculating default, see
@file{libavcodec/wavpackenc.c}.
@item compression_level (@emph{-f}, @emph{-h}, @emph{-hh}, and @emph{-x})
This option's syntax is consistent with @ref{libwavpack}'s.
@end table
@subsubsection Private options
@table @option
@item joint_stereo (@emph{-j})
Set whether to enable joint stereo. Valid values are:
@table @samp
@item on (@emph{1})
Force mid/side audio encoding.
@item off (@emph{0})
Force left/right audio encoding.
@item auto
Let the encoder decide automatically.
@end table
@item optimize_mono
Set whether to enable optimization for mono. This option is only effective for
non-mono streams. Available values:
@table @samp
@item on
enabled
@item off
disabled
