## 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
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. `vsyasm` is needed and `1.2.0` is suggested for windows platform. It can be downloaded through: http://yasm.tortall.net/Download.html .
 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
```
./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 --FrameRate=6 \
  --SourceWidth=3840 --SourceHeight=2160 --InputSampleBitDepth=8 --SampleBitDepth=8 \
  --thread_frames=1 --thread_rows=1 --preset=0 \
  --recon=. --initial_qp=32 --OutputFile=test.avs
```
