+ at subsection Options
+
+The following options are supported by FFmpeg's flac encoder.
+
+ at table @option
+ at item compression_level
+Sets the compression level, which chooses defaults for many other options
+if they are not set explicitly.
+
+ at item frame_size
+Sets the size of the frames in samples per channel.
+
+ at item lpc_coeff_precision
+Sets the LPC coefficient precision, valid values are from 1 to 15, 15 is the
+default.
+
+ at item lpc_type
+Sets the first stage LPC algorithm
+ at table @samp
+ at item none
+LPC is not used
+
+ at item fixed
+fixed LPC coefficients
+
+ at item levinson
+
+ at item cholesky
+ at end table
+
+ at item lpc_passes
+Number of passes to use for Cholesky factorization during LPC analysis
+
+ at item min_partition_order
+The minimum partition order
+
+ at item max_partition_order
+The maximum partition order

+Channel mode
+ at table @samp
+ at item auto

+ at item indep
+Chanels are independently coded
+ at item left_side

+ at item mid_side
+ at end table
+
+ at item exact_rice_parameters
+Chooses if rice parameters are calculated exactly or approximately.
+if set to 1 then they are chosen exactly, which slows the code down slightly and
+improves compression slightly.
+
+ at item multi_dim_quant
+Multi Dimensional Quantization. If set to 1 then a 2nd stage LPC algorithm is
+applied after the first stage to finetune the coefficients. This is quite slow
+and slightly improves compression.
