xavs2 is an open-source encoder of
AVS2-P2/IEEE1857.4 video coding standard.
VS2013 or later version of visual studio to open the solution file
then set the
xavs2 as the start project and build it.
shell executor, i.e. the bash in git for windows, is needed and should be found in
PATHvariable. For example, the path
C:\Program Files\Git\bincan be added if git-for-windows is installed.
2.13(or later version) is needed and should be put into the
build/vs2013directory. For windows platform, you can downloaded the packege and unpack the zip file to get
$ cd build/linux $ ./configure $ make
./xavs2 [-f encoder.cfg [-f seq.cfg]] [-p ParameterName=value] [--ParameterName=value]
Encode with configuration files
./xavs2 -f encoder.cfg -f seq4K.cfg -p InputFile=input.yuv -p FramesToBeEncoded=500 \ -p preset=0 -p recon=. -p initial_qp=32 -p OutputFile=test.avs
Enocde without configuraton files
./xavs2 -p InputFile=input.yuv --FramesToBeEncoded=500 --fps=50 \ --SourceWidth=3840 --SourceHeight=2160 --InputSampleBitDepth=8 --SampleBitDepth=8 \ --thread_frames=1 --thread_rows=1 --preset=0 \ --recon=. --initial_qp=32 --OutputFile=test.avs
