xavs2
xavs2 is an open-source encoder of AVS2-P2/IEEE1857.4
video coding standard.
A decoder, davs2, can be found at Github or Gitee (mirror in China).
Build it
Windows
Use VS2013
or later version of visual studio to open the solution file ./build/vs2013/xavs2.sln
,
then set the xavs2
as the start project and build it.
Notes
- A
shell executor
, i.e. the bash in git for windows, is needed and should be found inPATH
variable. For example, the pathC:\Program Files\Git\bin
can be added if git-for-windows is installed. nasm.exe
with version2.13
(or later version) is needed and should be put into thebuild/vs2013
directory. For windows platform, you can downloaded the packege and unpack the zip file to getnasm.exe
: https://www.nasm.us/pub/nasm/releasebuilds/2.14.02/win64/nasm-2.14.02-win64.zip
Linux
$ cd build/linux
$ ./configure
$ make
Try it
./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
