\begin{abstract}
This document is a user manual describing usage of the VTM reference software
for the VVC project. It applies to version 19.1 of the software.
\end{abstract}

\tableofcontents

\section{General Information}
Reference software is being made available to provide a reference
implementation of the HEVC standard being developed by the Joint 
Video Experts Team (JVET) regrouping experts from
ITU-T SG 16 and ISO/IEC SC29 WG5. One of the main goals of the
reference software is to provide a basis upon which to conduct
experiments in order to determine which coding tools provide desired
coding performance. It is not meant to be a particularly efficient
implementation of anything, and one may notice its apparent
unsuitability for a particular use. It should not be construed to be a
reflection of how complex a production-quality implementation of a
future VVC standard would be.

This document aims to provide guidance on the usage of the reference
software. It is widely suspected to be incomplete and suggestions for
improvements are welcome. Such suggestions and general inquiries may be
sent to the general JVET email reflector on
\url{https://lists.rwth-aachen.de/postorius/lists/jvet.lists.rwth-aachen.de/} 
(registration required).

\subsection*{Bug reporting}
Bugs should be reported on the issue tracker set up at:

\url{https://jvet.hhi.fraunhofer.de/trac/vvc/}

\section{Installation and compilation}
The software may be retrieved from the GitLab server located at:

\url{https://vcgit.hhi.fraunhofer.de/jvet/VVCSoftware_VTM}

Table~\ref{tab:project-files} lists the compiler environments and versions 
for which building the software is tested.

Note that the software makes use of C++14 language features, which may not
be available in older compilers.

\begin{table}[ht]
\caption{Supported compilers}
\label{tab:project-files}
\centering
\begin{tabular}{ll}
\hline
 \thead{Compiler environment} &
 \thead{Versions} \\
\hline
MS Visual Studio  & 2017 and 2019 \\
GCC               & 7.3, 8.3 and 9.3\\
Xcode/clang       & latest \\
\hline
\end{tabular}
\end{table}

By default the software is built as 64-bit binaries to be used on a 64-bit OS. 
This allows the software to use more than 2GB of RAM.

The software uses CMake to create platform-specific build files. 

\subsection {Build instructions for plain CMake (suggested)}

\textbf{Note:} A working CMake installation is required for building the software.

CMake generates configuration files for the compiler environment/development
environment on each platform. The following is a list of examples for Windows
(MS Visual Studio), macOS (Xcode) and Linux (make).

Open a command prompt on your system and change into the root directory
of this project.

Create a build directory in the root directory:
\begin{minted}{bash}
mkdir build 
\end{minted}
Use one of the following CMake commands, based on your platform. Feel free to change the 
commands to satisfy your needs.

\textbf{Windows Visual Studio 2015 64 Bit:}
\begin{minted}{bash}
cd build
cmake .. -G "Visual Studio 14 2015 Win64"
\end{minted}
Then open the generated solution file in MS Visual Studio.

\textbf{macOS Xcode:}
\begin{minted}{bash}
cd build
cmake .. -G "Xcode"
\end{minted}
Then open the generated work space in Xcode.

\textbf{Linux}

For generating Linux Release Makefile:
\begin{minted}{bash}
cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
\end{minted}
For generating Linux Debug Makefile:
\begin{minted}{bash}
cd build
cmake .. -DCMAKE_BUILD_TYPE=Debug
\end{minted}
Then type
\begin{minted}{bash}
make -j
\end{minted}
to build the software.

For more details, refer to the CMake documentation: \url{https://cmake.org/cmake/help/latest/}

\subsection {Build instructions for make}

\textbf{Note:}
The build instructions in this section require the make tool and Python
to be installed, which are part of usual Linux and macOS environments. 
See section \ref{windowsinstall} for installation instruction for Python 
and GnuWin32 on Windows.

Open a command prompt on your system and change into the root directory
of this project.

To use the default system compiler simply call:
\begin{minted}{bash}
make all
\end{minted}
For MSYS2 and MinGW:
Open an MSYS MinGW 64-Bit terminal and change into the root directory
of this project.

Call:
\begin{minted}{bash}
make all toolset=gcc
\end{minted}

\subsection{Tool Installation on Windows}
\label{windowsinstall}

Download CMake: \url{http://www.cmake.org/} and install it.

Python and GnuWin32 are not mandatory, but they simplify the build process for the user.

\begin{table}[ht]
\footnotesize
\centering
\begin{tabular}{ll}
\hline
Python     &    \url{https://www.python.org/downloads/release/python-371/} \\
GnuWin32   &    \url{https://sourceforge.net/projects/getgnuwin32/files/getgnuwin32/0.6.30/GetGnuWin32-0.6.3.exe/download} \\
\hline
\end{tabular}
\end{table}

To use MinGW, install MSYS2:
\url{http://repo.msys2.org/distrib/msys2-x86_64-latest.exe}

Installation instructions:
\url{https://www.msys2.org/}

Install the needed toolchains:
\begin{minted}{bash}
pacman -S --needed base-devel mingw-w64-i686-toolchain mingw-w64-x86_64-toolchain git subversion mingw-w64-i686-cmake mingw-w64-x86_64-cmake
\end{minted}

\section{Using the encoder}

\begin{minted}{bash}
EncoderApp [--help] [-li -c config.cfg] [-li --parameter=value]
\end{minted}

\begin{table}[ht]
\footnotesize
\centering
\begin{tabular}{lp{0.5\textwidth}}
\hline
 \thead{Option} &
 \thead{Description} \\
\hline
\texttt{--help} & Prints parameter usage. \\
\texttt{-li} & Applies to its next config file or command line parameter only to define  i-th layer encoding option. If empty, the configuration file applies to all layers\\
\texttt{-c} & Defines configuration file to use.  Multiple configuration files
     may be used with repeated --c options. \\
\texttt{--}\emph{parameter}\texttt{=}\emph{value}
    & Assigns value to a given parameter as further described below.
      Some parameters are also supported by shorthand
      "--\em{opt}~\emph{value}". These are shown in brackets after the parameter
      name in the tables of this document\\
\hline
\end{tabular}
\end{table}

Sample configuration files are provided in the cfg/ folder.
Parameters are defined by the last value encountered on the command line.
Therefore if a setting is set via a configuration file, and then a subsequent
command line parameter changes that same setting, the command line parameter
value will be used.

\subsection{GOP structure table}
\label{sec:gop-structure}
Defines the cyclic GOP structure that will be used repeatedly
throughout the sequence. The table should contain GOPSize lines,
named Frame1, Frame2, etc. The frames are listed in decoding
order, so Frame1 is the first frame in decoding order, Frame2 is
the second and so on. Among other things, the table specifies all
reference pictures kept by the decoder for each frame. This
includes pictures that are used for reference for the current
picture as well as pictures that will be used for reference in
the future. The encoder will not automatically calculate which
pictures have to be kept for future references, they must
be specified. Note that some specified reference frames for
pictures encoded in the very first GOP after an IDR frame might
not be available. This is handled automatically by the encoder,
so the reference pictures can be given in the GOP structure table
as if there were infinitely many identical GOPs before the
current one. Each line in the table contains the parameters used
for the corresponding frame, separated by whitespace:

\begin{itemize}
\item[]\textbf{Type}: Slice type, can be either I, P or B.

\item[]\textbf{POC}: Display order of the frame within a GOP, ranging
from 1 to GOPSize.

\item[]\textbf{QPOffset}: QP offset is added to the QP parameter to set
the final QP value to use for this frame.

\item[]\textbf{QPOffsetModelOff}: Offset parameter to a linear model to adjust final QP based on QP + QPoffset.

\item[]\textbf{QPOffsetModelScale}: Scale parameter to a linear model to adjust final QP based on QP + QPoffset.

\item[]\textbf{SliceCbQPOffset}: The slice-level Cb QP offset.

\item[]\textbf{SliceCrQPOffset}: The slice-level Cr QP offset.

\item[]\textbf{QPFactor}: Weight used during rate distortion
optimization. Higher values mean lower quality and less bits. Typical
range is between
0.3 and 1.

\item[]\textbf{tcOffsetDiv2}: An in-loop deblocking filter parameter for luma component, tcOffsetDiv2 
is added to the base parameter DeblockingFilterTcOffset_div2 to set the final tc_offset_div2 
parameter for this picture signalled in the slice segment header. The final 
value of tc_offset_div2 shall be an integer number in the range $-12..12$.

\item[]\textbf{betaOffsetDiv2}: An in-loop deblocking filter parameter for luma component, betaOffsetDiv2 
is added to the base parameter DeblockingFilterBetaOffset_div2 to set the final beta_offset_div2 
parameter for this picture signalled in the slice segment header. The final 
value of beta_offset_div2 shall be an integer number in the range $-12..12$.

\item[]\textbf{CbTcOffsetDiv2}: An in-loop deblocking filter parameter for Cb component, CbTcOffsetDiv2 
is added to the base parameter DeblockingFilterCbTcOffset_div2 to set the final tc_offset_div2 
parameter for this picture signalled in the slice segment header. The final 
value of tc_offset_div2 shall be an integer number in the range $-12..12$.

\item[]\textbf{CbBetaOffsetDiv2}: An in-loop deblocking filter parameter for Cb component, CbBetaOffsetDiv2 
is added to the base parameter DeblockingFilterCbBetaOffset_div2 to set the final beta_offset_div2 
parameter for this picture signalled in the slice segment header. The final 
value of beta_offset_div2 shall be an integer number in the range $-12..12$.

\item[]\textbf{CrTcOffsetDiv2}: An in-loop deblocking filter parameter for Cr component, CrTcOffsetDiv2 
is added to the base parameter DeblockingFilterCrTcOffset_div2 to set the final tc_offset_div2 
parameter for this picture signalled in the slice segment header. The final 
value of tc_offset_div2 shall be an integer number in the range $-12..12$.

\item[]\textbf{CrBetaOffsetDiv2}: An in-loop deblocking filter parameter for Cr component, CrBetaOffsetDiv2 
is added to the base parameter DeblockingFilterCrBetaOffset_div2 to set the final beta_offset_div2 
parameter for this picture signalled in the slice segment header. The final 
value of beta_offset_div2 shall be an integer number in the range $-12..12$.

\item[]\textbf{temporal_id}: Temporal layer of the frame. A frame cannot
predict from a frame with a higher temporal id. If a frame with higher
temporal IDs is listed among a frame's reference pictures, it is
not used, but is kept for possible use in future frames.

\item[]\textbf{num_ref_pics_active_L0}: Number of reference pictures in lists L0
that are used during coding.

\item[]\textbf{num_ref_pics_L0}: Size of reference picture list L0.
This includes pictures that are used for reference for the
current picture as well as pictures that will be used for reference in
the future.

\item[]\textbf{reference_pictures_L0}: A space-separated list of
num_ref_pics integers, specifying the POC of the reference pictures
kept, relative the POC of the current frame. The picture list shall be
ordered as their intendend order in the L0.
Note that any pictures not supplied in this list and in the list of L1 will be discarded and
therefore not available as reference pictures later.

\item[]\textbf{num_ref_pics_active_L1}: Number of reference pictures in lists L1
that are used during coding.

\item[]\textbf{num_ref_pics_L1}: Size of reference picture list L1.
This includes pictures that are used for reference for the
current picture as well as pictures that will be used for reference in
the future.

\item[]\textbf{reference_pictures_L1}: A space-separated list of
num_ref_pics integers, specifying the POC of the reference pictures
kept, relative the POC of the current frame. The picture list shall be
ordered as their intendend order in the L1.
Note that any pictures not supplied in this list and in the list of L0 will be discarded and
therefore not available as reference pictures later.

For example, consider the coding structure of Figure~\ref{fig:gop-example}.
This coding structure is of size 4. The pictures are listed in decoding
order. Frame1 shall therefore describe picture with $\textrm{POC}=4$. It
references picture 0, and therefore has 4 as a reference picture.
Similarly, Frame2 has a POC of 2, and since it references pictures 0 and
4, its reference pictures are listed as \verb|2 -2|. Frame3 is a special
case: even though it only references pictures with POC 0 and 2, it also
needs to include the picture with POC 4, which must be kept in order to
be used as a reference picture in the future. Note that picture with POC 4 can be
included in the L0 or L1. The reference picture list for Frame3 therefore becomes \verb|1 -1 -3|. 
Frame4 has a POC of 3 and its list of reference pictures is \verb|1 -1|.

Here, the frames used for prediction have been given higher
quality by assigning a lower QP offset. Also, the non-reference
frames have been marked as belonging to a higher temporal layer,
to make it possible to decode only every other frame. Note: each
line should contain information for one frame, so this
configuration would be specified as:

\begin{verbatim}
Frame1: P 4 1 0 0 0.5 0 0 0 0 0 0 0 1 1  4 1 1  4

%%
%% File, I/O and source parameters
%%
Shorthand alternatives for the parameter that can be used on the command line are shown in brackets after the parameter name.

\begin{OptionTableNoShorthand}{File, I/O and source parameters.}{tab:fileIO}
\Option{InputFile (-i)} &
%\ShortOption{-i} &
\Default{\NotSet} &
Specifies the input video file. If the file extension is Y4M, picture width, picture height, input bitdepth, chroma format and frame rate from Y4M will override the input from cfg and command line options.

Video data must be in a raw 4:2:0, or 4:2:2 planar format, 4:4:4 planar format (Y$'$CbCr, RGB or GBR), or in a raw 4:0:0 format. 

Note: When the bit depth of samples is larger than 8, each sample is encoded in
2 bytes (little endian, LSB-justified).
\\

\Option{BitstreamFile (-b)} &
%\ShortOption{-b} &
\Default{\NotSet} &
Specifies the output coded bit stream file.
\\

\Option{ReconFile (-o)} &
%\ShortOption{-o} &
\Default{\NotSet} &
Specifies the output locally reconstructed video file. If more than one layer is encoded (i.e. MaxLayers > 1), a reconstructed file is written for each layer and the layer index is added as suffix to ReconFile. If one or more dots exist in the file name, the layer id is added before the last dot, e.g. 'reconst.yuv' becomes 'reconst0.yuv' for layer id 0, 'reconst' becomes 'reconst0'. If the file extension is Y4M, picture width, picture height, bitdepth, chroma format and frame rate of the current encoding will be output to the Y4M file.
\\

\Option{SourceWidth (-wdt)}%
\Option{SourceHeight (-hgt)} &
%\ShortOption{-wdt}%
%\ShortOption{-hgt} &
\Default{0}%
\Default{0} &
Specifies the width and height of the input video in luma samples.
\\


\Option{SourceScalingRatioHor}%
\Option{SourceScalingRatioVer} &
\Default{1.0}%
\Default{1.0} &
Specifies a scaling ratio to apply in hor and vert direction to the pictures read from input video file.
Note: The SourceWidth and SourceHeight are multiplied by these scaling factors. This option is useful for spatial scalability in a multi layer scenario to use enhancement layer source when base layer source is not available. 
\\


\Option{InputBitDepth}
 &
%\ShortOption{\None} &
\Default{8} &
Specifies the bit depth of the input video.
\\

\Option{MSBExtendedBitDepth} &
%\ShortOption{\None} &
\Default{0} &
Extends the input video by adding MSBs of value 0. When 0, no extension is applied and the InputBitDepth is used.

The MSBExtendedBitDepth becomes the effective file InputBitDepth for subsequent processing.
\\

\Option{InternalBitDepth} &
%\ShortOption{\None} &
\Default{0} &
Specifies the bit depth used for coding. When 0, the setting defaults to the
value of the MSBExtendedBitDepth.

If the input video is a different bit depth to InternalBitDepth, it is
automatically converted by:
\begin{displaymath}
\left\lfloor
 \frac{\mathrm{Pel} * 2^{\mathrm{InternalBitDepth}}}{
     2^{\mathrm{MSBExtendedBitDepth}}}
\right\rfloor
\end{displaymath}

Note: The effect of this option is as if the input video is externally
converted to the MSBExtendedBitDepth and then to the InternalBitDepth
and then coded with this value as InputBitDepth. The codec has no
notion of different bit depths.
\\

\Option{OutputBitDepth} &
%\ShortOption{\None} &
\Default{0} &
Specifies the bit depth of the output locally reconstructed video file.
When 0, the setting defaults to the value of InternalBitDepth.
Note: This option has no effect on the decoding process.
\\

\Option{InputBitDepthC}%
\Option{MSBExtendedBitDepthC}%
\Option{OutputBitDepthC} &
%\ShortOption{\None} &
\Default{0}%
\Default{0}%
\Default{0} &
Specifies the various bit-depths for chroma components.  These only need
to be specified if non-equal luma and chroma bit-depth processing is
required. When 0, the setting defaults to the corresponding non-Chroma value.
\\

\Option{InputColourSpaceConvert} &
%\ShortOption{\None} &
\Default{\NotSet} &

  YCbCrToYCrCb & Swap the second and third components \\
  YCbCrtoYYY & Set the second and third components to the values in the first \\
  RGBtoGBR & Reorder the three components \\
\end{tabular}
\par
If no value is specified, no colour space conversion is applied. The list may eventually also include RGB to YCbCr or YCgCo conversions.
\\

\Option{SNRInternalColourSpace} &
%\ShortOption{\None} &
\Default{false} &
When this is set true, then no colour space conversion is applied prior to PSNR calculation, otherwise the inverse of InputColourSpaceConvert is applied.
\\

\Option{OutputInternalColourSpace} &
%\ShortOption{\None} &
\Default{false} &
When this is set true, then no colour space conversion is applied to the reconstructed video, otherwise the inverse of InputColourSpaceConvert is applied.
\\

\Option{InputChromaFormat} &
%\ShortOption{\None} &
\Default{420} &
Specifies the chroma format used in the input file. Permitted values (depending on the profile) are 400, 420, 422 or 444.
\\

\Option{ChromaFormatIDC (-cf)} &
%\ShortOption{-cf} &
\Default{0} &
Specifies the chroma format to use for processing. Permitted values (depending on the profile) are 400, 420, 422 or 444; the value of 0 indicates that the value of InputChromaFormat should be used instead.
\\

\Option{MSEBasedSequencePSNR} &
%\ShortOption{\None} &
\Default{false} &
When 0, the PSNR output is a linear average of the frame PSNRs; when 1, additional PSNRs are output which are formed from the average MSE of all the frames. The latter is useful when coding near-losslessly, where occasional frames become lossless.
\\

\Option{PrintFrameMSE} &
%\ShortOption{\None} &
\Default{false} &
When 1, the Mean Square Error (MSE) values of each frame will also be output alongside the default PSNR values.
\\

\Option{PrintSequenceMSE} &
%\ShortOption{\None} &
\Default{false} &
When 1, the Mean Square Error (MSE) values of the entire sequence will also be output alongside the default PSNR values.
\\

\Option{PrintWPSNR} &
%\ShortOption{\None} &
\Default{false} &
When 1, weighted PSNR (wPSNR) values of the entire sequence will also be output.
\\

\Option{PrintRefLayerMetrics} &
%\ShortOption{\None} &
\Default{false} &
When 1, PSNR between current layer and the first reference layer (rescaled to the current layer size if needed) of the entire sequence will also be output. Only the first reference layer is processed for this metric.
\\

\Default{false} &
When 1, CABAC zero word padding will be enabled. This is currently not the default value for the setting.
\\

\Option{ConformanceWindowMode} &
%\ShortOption{\None} &
\Default{1} &
Specifies how the parameters related to the conformance window are interpreted (cropping/padding).
The following modes are available:
\par
\begin{tabular}{cp{0.43\textwidth}}
0 & No cropping / padding \\
1 & Automatic padding to the next minimum CU size \\
2 & Padding according to parameters HorizontalPadding and VerticalPadding \\
3 & Cropping according to parameters ConfWinLeft, ConfWinRight, ConfWinTop and ConfWinBottom \\
\end{tabular}
\\

\\

\Option{TemporalSubsampleRatio (-ts)} &
%\ShortOption{-fs} &
\Default{1} &
Temporally subsamples the input video sequence. A value of $N$ will skip $(N-1)$ frames of input video after each coded input video frame. Note the FramesToBeEncoded does not account for the temporal skipping of frames, which will reduce the number of frames encoded accordingly. The reported bit rates will be reduced and VUI information is scaled so as to present the video at the correct speed. The minimum and default value is 1.
\\

\Option{FieldCoding} &
%\ShortOption{\None} &
\Default{false} &
When 1, indicates that field-based coding is to be applied.
\\

\Option{ReconFile (-o)} &
%\ShortOption{-o} &
\Default{\NotSet} &
Defines the reconstructed video file name. If empty, no file is generated. If the bitstream contains multiple layer and no single target layer is specified (i.e. TargetOutputLayerSet=-1), a reconstructed file is written for each layer and the layer index is added as suffix to ReconFile. If one or more dots exist in the file name, the layer id is added before the last dot, e.g. 'decoded.yuv' becomes 'decoded0.yuv' for layer id 0, 'decoded' becomes 'decoded0'. If the file extension is Y4M, picture width, picture height, bitdepth, chroma format and frame rate of the current decoding will be output to the Y4M file. As frame rate information is not mandatory in VVC bitstreams, best guess will be used. If no frame rate information is avaiable in a bitstream, a default frame rate (50 fps) will be output to the Y4M file.

this parameter is set to 0, the feature is disabled and all messages are
ignored. When set to 1 (default), the feature is enabled and the decoder
has the following behaviour:
\begin{itemize}
\item
  If Picture hash SEI messages are included in the bit stream, the same type
  of hash is calculated for each decoded picture and written to the
  log together with an indication whether the calculted value matches
  the value in the SEI message. 
  Decoding will continue even if there is a mismatch.

\item
  After decoding is complete, if any MD5sum comparison failed, a warning
  is printed and the decoder exits with the status EXIT_FAILURE

\item
  The per-picture MD5 log message has the following formats:
  [MD5:d41d8cd98f00b204e9800998ecf8427e,(OK)],
  [MD5:d41d8cd98f00b204e9800998ecf8427e,(unk)],
  [MD5:d41d8cd98f00b204e9800998ecf8427e,(***ERROR***)] [rxMD5:b9e1...]
  where, "(unk)" implies that no MD5 was signalled for this picture,
  "(OK)" implies that the decoder agrees with the signalled MD5,
  "(***ERROR***)" implies that the decoder disagrees with the signalled
  MD5. "[rxMD5:...]" is the signalled MD5 if different.
\end{itemize}
\\

\Option{OutputDecodedSEIMessagesFilename} &
%\ShortOption{\None} &
\Default{\NotSet} &
When a non-empty file name is specified, information regarding any decoded SEI messages will be output to the indicated file. If the file name is '-', then stdout is used instead.
\\

\Option{SEICTIFilename} &
%\ShortOption{\None} &
\Default{\NotSet} &
Specifies that the colour transform information (CTI) SEI message should be applied to the output video, with the output written to this file.
If no value is specified, the SEI message is ignored and no mapping is applied.
\\

\Option{SEIAnnotatedRegionsInfoFilename} &
%\ShortOption{\None} &
\Default{\NotSet} &
When a non-empty file name is specified, object information using the decoded SEI messages will be output to the indicated file.
If no value is specified, the SEI message will not be output.
\\

\Option{OutputColourSpaceConvert} &
\Default{\NotSet} &
Specifies the colour space conversion to apply to 444 video. Permitted values are:
\par

  YCrCbToYCbCr & Swap the second and third components \\
  GBRtoRGB     & Reorder the three components \\
\end{tabular}
If no value is specified, no colour space conversion is applied. The list may eventually also include RGB to YCbCr or YCgCo conversions.\\
\\

\Option{PYUV} &
\Default{false} &
When true, output 10-bit and 12-bit YUV data as 5-byte and 3-byte (respectively) packed YUV data. See doc/pyuv_format.pdf for details. Ignored for interlaced output.
\\

\Option{SEINoDisplay} &
\Default{false} &
When true, do not output frames for which there is an SEI NoDisplay message.
\\

\Option{ClipOutputVideoToRec709Range} &
%\ShortOption{\None} &
\Default{0} &
If 1 then clip output video to the Rec. 709 Range on saving when OutputBitDepth is less than InternalBitDepth.
\\

\end{OptionTableNoShorthand}


\subsection{Using the decoder analyser}
If the decoder is compiled with the macro RExt__DECODER_DEBUG_BIT_STATISTICS defined as 1 (either externally, or by editing TypeDef.h), the decoder will gather fractional bit counts associated with the different syntax elements, producing a table of the number of bits per syntax element, and where appropriate, according to block size and colour component/channel.
The Linux makefile will compile both the analyser and standard version when the `all' or `everything' target is used (where the latter will also build  high-bit-depth executables).



\section{Block statistics extension}
\label{sec:block-stat-extens}

The block statistics extension enables straightforward visualization and statistical analysis of coding tool
usage in encoded bitstreams. The extension enables the reference
software encoder and decoder to write out statistics files in a configurable
way, which in turn can be loaded into a suitable YUV player for overlay of the
reconstructed YUV sequence, or can be used for statistical analysis at a
selectable scope (e.g. block/picture/sequence level). An example implementation
for such visualization is available with the open-source YUView player
(\url{https://github.com/IENT/YUView}). 


\subsection{Usage}
\label{sec:usage}

The software has to be compiled with the macros ENABLE_TRACING and
K0149_BLOCK_STATISTICS  defined as 1. The statistics can be written by either
encoder or decoder.

The extension adds additional trace channels to the ``dtrace'' functionality of
the software. The following trace channels were added:
\begin{description}
\item[D_BLOCK_STATISTICS_ALL] All syntax elements are written, no matter whether
  they are actually encoded or derived.
\item[D_BLOCK_STATISTICS_CODED] Tries to write only syntax elements, which have
  also been encoded.
\end{description}

The following additional encoder options are available (part of ``dtrace''). See
the file dtrace_next.h for more details.

\begin{OptionTableNoShorthand}{Decoder options}{tab:decoder-block-statistics}
\Option{TraceFile} &
%\ShortOption{\None} &
\Default{\None} &
File name of the produced trace file.
\\

\Option{TraceRule} &
%\ShortOption{-b} &
\Default{\NotSet} &
Specifies which traces should be saved, and for which POCs.
\\

\end{OptionTableNoShorthand}

Concrete examples of calls for  generating a block statistics file are:
\begin{minted}{bash}
bin/DecoderAppStatic -b str/BasketballDrive_1920x1080_QP37.vvc \
    --TraceFile="stats/BasketballDrive_1920x1080_QP37_coded.vtmbmsstats" \
    --TraceRule="D_BLOCK_STATISTICS_CODED:poc>=0"

bin/DecoderAppStatic -b str/BasketballDrive_1920x1080_QP37.vvc \
    --TraceFile="stats/BasketballDrive_1920x1080_QP37_all.vtmbmsstats" \
    --TraceRule="D_BLOCK_STATISTICS_ALL:poc>=0"   
\end{minted}


\subsection{Block statistics file formats}
\label{sec:block-stat-file}
The trace file will contain a header listing information of all available block
statistics. For each statistic it lists a type and a scale for vectors or range
for integers if applicable: 
\begin{verbatim}
# VTMBMS Block Statistics
# Sequence size: [832x 480]
# Block Statistic Type: PredMode; Flag; 
# Block Statistic Type: MergeFlag; Flag; 
# Block Statistic Type: MVL0; Vector; Scale: 4
# Block Statistic Type: MVL1; Vector; Scale: 4
# Block Statistic Type: IPCM; Flag; 
# Block Statistic Type: Y_IntraMode; Integer; [0, 73]
# Block Statistic Type: Cb_IntraMode; Integer; [0, 73]
\end{verbatim}

Two formats are available for the statistics for each block, a human readable
format and a CSV based format. The header remains the same for both cases. 

For both formats each row contains the information for one block statistic. The
order of the data is: picture order count (POC), location of top left corner of
the block, size of the block, name of the statistic, and value of the
statistic. 
The macro BLOCK_STATS_AS_CSV is available in order to choose the required format.
The human readable format can also be easily processed with other software, for
example YUView, using regular expressions. The CSV based formats provides the
universal interface required by spreadsheet applications.

The human readable format is based on the format used for the other dtrace
statistics. Some examples for this format are:
\begin{verbatim}
BlockStat: POC 16 @( 112,   0) [ 8x 8] SkipFlag=1
BlockStat: POC 16 @( 112,   0) [ 8x 8] InterDir=1
BlockStat: POC 16 @( 112,   0) [ 8x 8] MergeFlag=1
BlockStat: POC 16 @( 112,   0) [ 8x 8] MergeIdx=0
BlockStat: POC 16 @( 112,   0) [ 8x 8] MergeType=0
BlockStat: POC 16 @( 112,   0) [ 8x 8] MVPIdxL0=255
BlockStat: POC 16 @( 112,   0) [ 8x 8] MVPNumL0=255
BlockStat: POC 16 @( 112,   0) [ 8x 8] RefIdxL0=0
BlockStat: POC 16 @( 112,   0) [ 8x 8] MVDL0={   0,   0}
BlockStat: POC 16 @( 112,   0) [ 8x 8] MVL0={ -70,  18}
BlockStat: POC 16 @( 112,   8) [ 8x 8] PredMode=0
BlockStat: POC 16 @( 112,   8) [ 8x 8] PartSize=0
\end{verbatim}

Some examples of the CSV based format are:
\begin{verbatim}
BlockStat;16; 112;   0; 8; 8;SkipFlag;1
BlockStat;16; 112;   0; 8; 8;InterDir;1
BlockStat;16; 112;   0; 8; 8;MergeFlag;1
BlockStat;16; 112;   0; 8; 8;MergeIdx;0
BlockStat;16; 112;   0; 8; 8;MergeType;0
BlockStat;16; 112;   0; 8; 8;MVPIdxL0;255
BlockStat;16; 112;   0; 8; 8;MVPNumL0;255
BlockStat;16; 112;   0; 8; 8;RefIdxL0;0
BlockStat;16; 112;   0; 8; 8;MVDL0;   0;   0
BlockStat;16; 112;   0; 8; 8;MVL0; -70;  18
BlockStat;16; 112;   8; 8; 8;PredMode;0
BlockStat;16; 112;   8; 8; 8;PartSize;0
\end{verbatim}

\subsection{Visualization}
\label{sec:visualization}

The block statistics can be viewed with YUView, which is freely available under
GPLv3: \url{https://github.com/IENT/YUView}. The latest releases and the master
branch have the functionality required for  viewing the block statistics. YUView
assumes that the file extension of block statistics file is
“.vtmbmsstats”. However, if a file is not recognized you can choose from a list
of supported file formats.


Statistics can be overlaid with YUV sequences. Some example snapshots are:

\begin{figure}[htpb]
  \centering
  \includegraphics[width=0.8\linewidth]{figures/YUView}
  \caption{YUView}
  \label{fig:yuview}
\end{figure}

\begin{figure}[htpb]
  \centering
  \includegraphics[width=0.5\linewidth]{figures/raceHorsesShot2MotionVectors}
  \caption{Motion vectors}
  \label{fig:motion-vectors}
\end{figure}


\begin{figure}[htpb]
  \centering
  \includegraphics[width=0.5\linewidth]{figures/raceHorsesShot3SkipFlag}
  \caption{Skip flag}
  \label{fig:skip-flag}
\end{figure}

\subsection{Adding statistics}
\label{sec:adding-statistics}

In order to add further block statistics, do the following:


\begin{description}
\item[source/Lib/CommonLib/dtrace_blockstatistics.h]
  Add your statistic to the BlockStatistic enum:	
\begin{minted}{c++}
enum class BlockStatistic {
  // general
  PredMode,
  PartSize,
  Depth,
\end{minted}
  
Further, add your statistic to the map blockstatistic2description:
\begin{minted}{c++}
static const std::map<BlockStatistic, 
  std::tuple<std::string, BlockStatisticType, std::string>> 
  blockstatistic2description =
{
  { BlockStatistic::PredMode, 
    std::tuple<std::string, BlockStatisticType, std::string>
    {"PredMode", BlockStatisticType::Flag, ""}},
  { BlockStatistic::MergeFlag,
    std::tuple<std::string, BlockStatisticType, std::string>
    {"MergeFlag", BlockStatisticType::Flag, ""}},
  { BlockStatistic::MVL0,
    std::tuple<std::string, BlockStatisticType, std::string>
    {"MVL0", BlockStatisticType::Vector, "Scale: 4"}},
  YOURS
\end{minted}


\item[source/Lib/CommonLib/dtrace_blockstatistics.cpp] All code for
  writing syntax elements is kept in this file in
  getAndStoreBlockStatistics. This function is called once for each
  CTU, after it has been en/decoded. The following macros have been
  defined to facilitate writing of block statistics:
\begin{minted}{c++}
DTRACE_BLOCK_SCALAR(ctx,channel,cs_cu_pu,stat_type,val)   
DTRACE_BLOCK_SCALAR_CHROMA(ctx,channel,cs_cu_pu,stat_type,val)
DTRACE_BLOCK_VECTOR(ctx,channel,cu_pu,stat_type,v_x,v_y)    
DTRACE_BLOCK_AFFINETF(ctx,channel,pu,stat_type,v_x0,v_y0,v_x1,v_y1,v_x2,v_y2) 
\end{minted}

An example:
\begin{minted}{c++}
DTRACE_BLOCK_SCALAR(g_trace_ctx, D_BLOCK_STATISTICS_ALL, 
  cu, GetBlockStatisticName(BlockStatistic::PredMode), cu.predMode);
\end{minted}


\item[Block statistics for debugging] The statistics can also be used
  to write out other data, not just syntax elements. Add your
  statistics to dtrace_blockstatistics.h. Where it should be used the
  following headers have to be included:
\begin{minted}{c++}
#include "dtrace_next.h"
#include "dtrace_blockstatistics.h"
\end{minted}
\end{description}


\section{Coding tool statistics extension for green metadata}
\label{sec:green-meta-sei}

The encoder and the decoder include an extension that generates coding tool statistic. In the encoder, the extension calculates green metadata for encoding green SEI messages, in particular complexity metrics for decoder power reduction. The decoder extension can be used for cross-checking the correct functionality of the encoding extension.

The output of the analyzer can be enabled with the option 'GMFA' (Green Metadata Feature Analyzer). The output file name is specified with the flag 'GMFAFile'.
Furthermore, it is possible to generate a framewise analysis with the option 'GMFAFramewise'. The output file is generated in a Matlab-readable way. Here is an example for both the encoder and the decoder:

\begin{minted}{bash}
bin/EncoderAppStatic -b bitstream.vvc  --GMFA 1 --GMFAFramewise=1 --GMFAFile="bitstream.m" [encoder options]

bin/DecoderAppStatic -b bitstream.vvc  --GMFA 1 --GMFAFramewise=1 --GMFAFile="bitstream.m" [decoder options]
\end{minted}

The output file contains arrays with statistics on the use of coding tools on block-size level. As an example, the number of intra-coded blocks is returned as:

\begin{minted}{bash}
n.intraBlocks = [...
0  0  0  0  0  0  0  0 ;...
0  0  0  16412  2142  54  0  0 ;...
0  0  41654  41906  9780  665  27  0 ;...
0  0  23494  22855  8641  906  26  0 ;...
0  0  4670  4797  4030  1215  60  0 ;...
0  0  433  507  881  1104  84  0 ;...
0  0  38  48  43  122  131  0 ;...
0  0  0  0  0  0  0  0 ];
\end{minted}

The horizontal position indicates the logarithm to the basis 2 block width (1, 2, 4, .., 128) and the vertical position the block height, accordingly. In this example, the bit stream contains $16{,}412$ intra-coded blocks of size $8\times 2$.

More information can be found in JVET-P0085 and \url{10.1109/ICIP40778.2020.9190840}.




\section{Using the stream merge tool}
\label{sec:stream-merge-tool}

The StreamMergeApp tool takes multiple single-layer (singe nuh_layer_id) bistreams 
as inputs and merge them into a multi-layer bistream by interleaving the Picture Units
from the input single layer bistreams. During the merge, the tool assigns a new unique
nuh_layer_id for each input bitstream as well as unique parameter sets identifiers for each layer.
Then the decoder can specify which layer bitstream to be decoded through the command line option "-p nuh_layer_id".

Some current limitations of the tool:
\begin{itemize}
\item All input bitstreams are single layer and thus all layers in the output bitstream are independent layers.
\item Each layer in the output bitstream is abitrarily put in an individual OLS and is also an output layer.
\item All parameter sets from the input bitstreams are treated as different parameter sets. There is thus no parameters sets sharing in the output bitstream.
\item The slice header in the input bitstreams shall contain no picture header structure and no alf information.
\end{itemize}


\subsection{Usage}
\label{sec:stream-merge-usage}

\begin{minted}{bash}
StreamMergeApp 	<bitstream1> <bitstream2> [<bitstream3> ...] <outfile>
\end{minted}

The command line options bistreamX specify the file names of the input single-layer 
bistreams. At least two input bitstreams need to be specified. The merged multi-layer 
bistream will be stored into the outfile.




\section{Using the subpicture merge tool}
\label{sec:subpicture-merge-tool}

The SubpicMergeApp takes multiple bitstreams as inputs and merges them into one output bitstream where each input bitstream forms a single subpicture. Subpicture layout and input bitstreams are defined in a subpicture list file. Sequence parameter set and picture parameter set are modified accordingly based on the layout.

The merge tool has an alternative mode for merging YUV files. This mode can be used for verifying YUV output after decoding merged bitstream.

If VTM encoder is used for encoding input bitstreams, it is recommnended that ALF, CCALF, joint chroma coding, LMCS and AMaxBT are disabled. This prevents those tools having parameters with different values in different subpictures which would result in merged bitstream being non-conformant.

\subsection{Usage}
\label{sec:subpicture-merge-usage}

\begin{minted}{bash}
SubpicMergeApp [-l <subpiclistfile>] [-o <outfile>] [-m 0|1] [-yuv 0|1] [-d <bitdepth>] [-f 400|420|422|444]
\end{minted}

\begin{table}[ht]
\footnotesize
\centering
\begin{tabular}{lp{0.5\textwidth}}
\hline
 \thead{Option} &
 \thead{Description} \\
\hline
\texttt{--help} & Prints parameter usage. \\
\texttt{-l} & File containing list of input pictures to be merged \\
\texttt{-o} & Output file name \\
\texttt{-m} & Enable mixed NALU type bitstreams merging \\
\texttt{-yuv} & Perform YUV merging (instead of bitstream merging) \\
\texttt{-d} & Bitdepth for YUV merging \\
\texttt{-f} & Chroma format for YUV merging, 420 (default), 400, 422 or 444 \\
\hline
\end{tabular}
\end{table}

Format of the subpicture list file given with '-l' command is as follows:

\begin{minted}{bash}
subpic1_width  subpic1_height  subpic1_x  subpic1_y  subpic1_bitstream_file
subpic2_width  subpic2_height  subpic2_x  subpic2_y  subpic2_bitstream_file
...
subpicN_width  subpicN_height  subpicN_x  subpicN_y  subpicN_bitstream_file
\end{minted}

Coordinates x and y define the location of top-left corner of the subpicture in the merged picture. Parameters width, height, x and y are given in units of luma samples.

YUV merging uses the same file format, only difference being that YUV file name is supplied instead of bitstream file name.
