 For example, the path `C:\Program Files\Git\bin` can be added if git-for-windows is installed.

 A later version `1.3.0`, can be found in https://github.com/luofalei/yasm/tree/vs2013 .

### Linux
```
$ cd build/linux
$ ./configure
$ make
```

## Try it

```
./davs2 -i test.avs -o test_dec.yuv [-r test_rec.yuv -t N]
```
