@item error-resilient
Enable error resiliency features.
+@item sharpness @var{integer}
+Increase sharpness at the expense of lower PSNR.
+The valid range is [0, 7].

during configuration. You need to explicitly configure the build with
@option{--enable-libxavs2}.
+The following standard libavcodec options are used:
+@itemize
+@item
+@option{b} / @option{bit_rate}
+@item
+@option{g} / @option{gop_size}
+@item
+@option{bf} / @option{max_b_frames}
+@end itemize
+
+The encoder also has its own specific options:
@subsection Options
@table @option
For example to specify libxavs2 encoding options with @option{-xavs2-params}:
@example
-ffmpeg -i input -c:v libxavs2 -xavs2-params preset_level=5 output.avs2
+ffmpeg -i input -c:v libxavs2 -xavs2-params RdoqLevel=0 output.avs2
@end example
@end table
indicating the source of the video pictures. The default is @samp{unspecified},
can be @samp{component}, @samp{pal}, @samp{ntsc}, @samp{secam} or @samp{mac}.
For maximum compatibility, use @samp{component}.
+@item a53cc @var{boolean}
+Import closed captions (which must be ATSC compatible format) into output.
+Default is 1 (on).

All encoders support the following options:
-@itemize
-@item
-@option{low_power}
-
+@table @option
+@item low_power
Some drivers/platforms offer a second encoder for some codecs intended to use
less power than the default encoder; setting this option will attempt to use
that encoder. Note that it may support a reduced feature set, so some other
options may not be available in this mode.
-@end itemize
+
+@item idr_interval
+Set the number of normal intra frames between full-refresh (IDR) frames in
+open-GOP mode. The intra frames are still IRAPs, but will not include global
+headers and may have non-decodable leading pictures.
+
+@item b_depth
+Set the B-frame reference depth. When set to one (the default), all B-frames
+will refer only to P- or I-frames. When set to greater values multiple layers
+of B-frames will be present, frames in each layer only referring to frames in
+higher layers.
+
+@item rc_mode
+Set the rate control mode to use. A given driver may only support a subset of
+modes.
+
+Possible modes:
+@table @option
+@item auto
+Choose the mode automatically based on driver support and the other options.
+This is the default.
+@item CQP
+Constant-quality.
+@item CBR
+Constant-bitrate.
+@item VBR
+Variable-bitrate.
+@item ICQ
+Intelligent constant-quality.
+@item QVBR
+Quality-defined variable-bitrate.
+@item AVBR
+Average variable bitrate.
