[FFmpeg-devel] [PATCH v5 1/1] avcodec: add external enc libvvenc for H266/VVC
Christian Bartnik

Wed Jun 5 22:51:46 EEST 2024
From: Thomas Siedel <thomas.ff at spin-digital.com>
Add external encoder VVenC for H266/VVC encoding.
Register new encoder libvvenc.
Add libvvenc to wrap the vvenc interface.
libvvenc implements encoder option: preset,qp,qpa,period,
passlogfile,stats,vvenc-params,level,tier.
Enable encoder by adding --enable-libvvenc in configure step.

+VVenC H.266/VVC encoder wrapper.
+
+This encoder requires the presence of the libvvenc headers and library
+during configuration. You need to explicitly configure the build with
+ at option{--enable-libvvenc}.
+
+The VVenC project website is at
+ at url{https://github.com/fraunhoferhhi/vvenc}.
+
+ at subsection Supported Pixel Formats
+
+VVenC supports only 10-bit color spaces as input. But the internal (encoded)
+bit depth can be set to 8-bit or 10-bit at runtime.
+
+ at subsection Options
+
+ at table @option
+ at item b
+Sets target video bitrate.
+
+ at item g
+Set the GOP size. Currently support for g=1 (Intra only) or default.
+
+ at item preset
+Set the VVenC preset.
+
+ at item levelidc
+Set level idc.
+
+ at item tier
+Set vvc tier.
+
+ at item qp
+Set constant quantization parameter.
+
+ at item subopt @var{boolean}
+Set subjective (perceptually motivated) optimization. Default is 1 (on).
+
+ at item bitdepth8 @var{boolean}
+Set 8bit coding mode instead of using 10bit. Default is 0 (off).
+
+ at item period
+set (intra) refresh period in seconds.
+
+ at item vvenc-params
+Set vvenc options using a list of @var{key}=@var{value} couples separated
+by ":". See @command{vvencapp --fullhelp} or @command{vvencFFapp --fullhelp} for a list of options.
+
+For example, the options might be provided as:
+
+ at example
+intraperiod=64:decodingrefreshtype=idr:poc0idr=1:internalbitdepth=8
+ at end example
+
+For example the encoding options might be provided with @option{-vvenc-params}:
+
+ at example
+ffmpeg -i input -c:v libvvenc -b 1M -vvenc-params intraperiod=64:decodingrefreshtype=idr:poc0idr=1:internalbitdepth=8 output.mp4
+ at end example
+
+ at end table
