@item packet_loss (@emph{expect-loss})
Set expected packet loss percentage. The default is 0.
+@item fec (@emph{n/a})
+Enable inband forward error correction. @option{packet_loss} must be non-zero
+to take advantage - frequency of FEC 'side-data' is proportional to expected packet loss.
+Default is disabled.
+
@item application (N.A.)
Set intended application type. Valid options are listed below:
@end table
-@anchor{libwavpack}
-@section libwavpack
-
-A wrapper providing WavPack encoding through libwavpack.
-
-Only lossless mode using 32-bit integer samples is supported currently.
-
-Requires the presence of the libwavpack headers and library during
-configuration. You need to explicitly configure the build with
-@code{--enable-libwavpack}.
-
-Note that a libavcodec-native encoder for the WavPack codec exists so users can
-encode audios with this codec without using this encoder. See @ref{wavpackenc}.
-
-@subsection Options
-
-@command{wavpack} command line utility's corresponding options are listed in
-parentheses, if any.
-
-@table @option
-@item frame_size (@emph{--blocksize})
-Default is 32768.
-
-@item compression_level
-Set speed vs. compression tradeoff. Acceptable arguments are listed below:
-
-@table @samp
-@item 0 (@emph{-f})
-Fast mode.
-
-@item 1
-Normal (default) settings.
-
-@item 2 (@emph{-h})
-High quality.
-
-@item 3 (@emph{-hh})
-Very high quality.
-
-@item 4-8 (@emph{-hh -x}@var{EXTRAPROC})
-Same as @samp{3}, but with extra processing enabled.
-
-@samp{4} is the same as @option{-x2} and @samp{8} is the same as @option{-x6}.
-
-@end table
-@end table
-
@anchor{mjpegenc}
@section mjpeg
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
@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.

@table @option
-@item format
+@item format @var{integer}
Can be set to either @code{j2k} or @code{jp2} (the default) that
makes it possible to store non-rgb pix_fmts.
+@item tile_width @var{integer}
+Sets tile width. Range is 1 to 1073741824. Default is 256.
+
+@item tile_height @var{integer}
+Sets tile height. Range is 1 to 1073741824. Default is 256.
+
+@item pred @var{integer}
+Allows setting the discrete wavelet transform (DWT) type
+@table @option
+@item dwt97int (Lossy)
+@item dwt53 (Lossless)
+@end table
+Default is @code{dwt97int}
+
+@item sop @var{boolean}
+Enable this to add SOP marker at the start of each packet. Disabled by default.
+
+@item eph @var{boolean}
+Enable this to add EPH marker at the end of each packet header. Disabled by default.
+
+@item prog @var{integer}
+Sets the progression order to be used by the encoder.
+Possible values are:
+@table @option
+@item lrcp
+@item rlcp
+@item rpcl
+@item pcrl
+@item cprl
+@end table
+Set to @code{lrcp} by default.
+
+@item layer_rates @var{string}
+By default, when this option is not used, compression is done using the quality metric.
+This option allows for compression using compression ratio. The compression ratio for each
+level could be specified. The compression ratio of a layer @code{l} species the what ratio of
+total file size is contained in the first @code{l} layers.
+
+Example usage:
+
+@example
+ffmpeg -i input.bmp -c:v jpeg2000 -layer_rates "100,10,1" output.j2k
+@end example
+
+This would compress the image to contain 3 layers, where the data contained in the
+first layer would be compressed by 1000 times, compressed by 100 in the first two layers,
+and shall contain all data while using all 3 layers.
