+
+Scalable Video Technology for HEVC (SVT-HEVC) encoder wrapper.
+
+This encoder requires the presence of the headers and
+library during configuration. You need to explicitly configure the
+build with @code{--enable-libsvthevc}. The library is detected using
+@command{pkg-config}.
+
+For more information about the library see
+@url{https://github.com/intel/SVT-HEVC.git}.
+
+@subsection Options
+
+The following FFmpeg global options affect the configurations of the
+libsvt_hevc encoder:
+
+@table @option
+@item b (@emph{bitrate})
+Set the bitrate (as a number of bits per second). Default is 7M.
+
+@item g / @option{gop_size}
+Set the GOP size. Default is -2 (unspecified).
+
+@item flags +cgop
+Enable closed GOP.
+
+@item qmin (@emph{min-q})
+Default is 10
+
+@item qmax (@emph{max-q})
+Default is 48
+
+Set minimum/maximum quantisation values. Valid range is from 0 to 51
+(Only used when bit rate control mode @option{rc} is set to 1(vbr) mode.
+It is required that qmax >= qmin).
+
+@item profile (@emph{profile})
+Set profile restrictions. Can assume one of the following possible values:
+
+@table @samp
+@item main
+main profile
+@item main10
+main10 profile
+@end table
+
+Default is 2 (main10).
+
+@item level (@emph{level})
+
+@option{level} sets the value of @emph{level}.
+Set level (level_idc). Default is 0 (to be determined by the encoder).
+
+@end table
+
+The encoder also has its own specific options:
+
+@table @option
+@item aud (@emph{aud})
+Enable use of access unit delimiters when set to 1. Default is 0 (Off).
+
+@item hielevel
+Set hierarchical levels. Can assume one of the following possible values:
+
+@table @samp
+@item flat
+none hierarchy level
+@item 2level
+2-level hierarchy
+@item 3level
+3-level hierarchy
+@item 4level
+4-level hierarchy
+@end table
+
+Default is 3.
+
+@item la_depth
+Set look-ahead depth, depending on @option{rc}: for @var{vbr}, it's recommended
+to unset it and use the default value (the intra period); for @var{cqp}, better
+specify the look-ahead depth.
+
+The range is @var{-1-256}. Default is -1 (unset and the default value to be used).
+
+@item preset
+Set the quality vs density tradeoff point at which the encoding is to be performed.
+Higher perset value, higher density and lower quality.
+
+The range is @var{0-12}. Default is 9.
+
+@item tier
+Set @emph{general_tier_flag}. This may affect the level chosen for the stream
+if it is not explicitly specified. Can assume one of the following possible values:
+
+@table @samp
+@item main
+main tier
+@item high
+high tier
+@end table
+
+Default is 1 (main).
+
+@item rc
+Set bit rate control mode. Can assume one of the following possible values:
+
+@table @samp
+@item cqp
+Constant QP (CQP) mode
+@item vbr
+Variable Bit Rate (VBR) mode
+@end table
+
+Default is 0 (cqp).
+
+@item qp
+Initial quantization parameter for the intra pictures used when
+@option{rc} is cqp mode. The range is from @var{0-51}. Default is 32.
+
+@item sc_detection
+Enables or disables the scene change detection algorithm. Default is 0 (disabled).
+
+@item tune
+Set quality tuning mode. Can assume one of the following possible values:
+
+@table @samp
+@item sq
+Visually optimized mode
+@item oq
+PSNR / SSIM optimized mode
+@item vmaf
+VMAF optimized mode
+@end table
+
+Default is 1 (oq).
+
+@item bl_mode
+Enables or disables Random Access Prediction. Default is 0 (disabled).
