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

#### Notes
1. 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.
2. `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

### 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 -
```
