davs2
davs2 is an open-source decoder of AVS2-P2/IEEE1857.4
video coding standard.
An encoder, xavs2, can be found at Github or Gitee (mirror in China).
Linux(Ubuntu-16.04): Windows(VS2013):
Compile it
Windows
Use VS2013 or latest version of visual studio open the ./build/vs2013/davs2.sln
solution

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

Linux
$ cd build/linux
$ ./configure
$ make
Try it
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 -
