Using uvg266 VVC

Debugging:

./uvg266 -i BQMall_832x480_60.yuv -o BQMall.266 -n 10 --no-sao --threads=0 --no-wpp -p 1 --rd=0 --fast-residual-cost=32 --no-deblock > debug.txt

./DecoderAnalyserApp -b BQMall.266 --TraceFile=trace.txt --TraceRule=D_COMMON,D_CABAC,D_SYNTAX,D_NALUNITHEADER,D_HEADER:poc>=0 -o rec.yuv

Example:

uvg266 --input BQMall_832x480_60.yuv --output out.vvc

The mandatory parameters are input and output. If the resolution of the input file is not in the filename, or when pipe is used, the input resolution must also be given: .

The default input format is 8-bit yuv420p for 8-bit and yuv420p10le for 10-bit. Input format and bitdepth can be selected with and .

Speed and compression quality can be selected with , or by setting the options manually.

LP-GOP syntax The LP-GOP syntax is "lp-g(num)d(num)t(num)", where g = GOP length. d = Number of GOP layers. t = How many references to skip for temporal scaling, where 4 means only every fourth picture needs to be decoded.

Presets The names of the presets are the same as with x264: ultrafast, superfast, veryfast, faster, fast, medium, slow, slower, veryslow and placebo. The effects of the presets are listed in the following table, where the names have been abbreviated to fit the layout in GitHub.

uvg266 library See uvg266.h for the library API and its documentation.

When using the static uvg266 library on Windows, macro UVG_STATIC_LIB must be defined. On other platforms it's not strictly required.

The needed linker and compiler flags can be obtained with pkg-config.

Compiling uvg266 If you have trouble regarding compiling the source code, please make an issue about in Github. Others might encounter the same problem and there is probably much to improve in the build process. We want to make this as simple as possible.

CMake Depending on the platform, some additional tools are required for compiling uvg266 with CMake. For Ubuntu, the required packages are build-essential cmake.

First, configure the build:

Then, build the project:

Finally, if you want to install uvg266:

Visual Studio natively supports opening the CMakeLists.txt of the CMake build package has been installed. Otherwise CMake-CLI can be used to generate the Visual Studio project files.
