Use VS2013 or latest version of visual studio open the ./build/vs2013/davs2.sln solution and set the davs2 as the start project.

A shell executor, i.e. the bash in git for windows, is needed and should be found in PATH variable. For example, the path C:\Program Files\Git\bin can be added if git-for-windows is installed.
nasm.exe with version 2.13 (or later version) is needed and should be put into the PATH directory. For windows platform, you can downloaded the packege and unpack the zip file to get nasm.exe: https://www.nasm.us/pub/nasm/releasebuilds/2.14.02/win64/nasm-2.14.02-win64.zip

Decode AVS2 stream test.avs with 1 thread and output to a YUV file named dec.yuv.

./davs2 -i test.avs -t 1 -o dec.yuv

Decode AVS2 stream test.avs and display the decoding result via ffplay.

./davs2 -i test.avs -t 1 -o stdout | ffplay -i -

--input=test.avs	-i test.avs	Setting the input bitstream file
--output=dec.yuv	-o dec.yuv	Setting the output YUV file
--psnr=rec.yuv	-r rec.yuv	Setting the reference reconstruction YUV file
--threads=N	-t N	Setting the threads for decoding (default: 1)
--md5=M	-m M	Reference MD5, used to check whether the output YUV is right
