Go bindings for [mpeg5/xevd](https://github.com/mpeg5/xevd)
MPEG-5 EVC decoder.
## Requirements
requires xevd [install](https://github.com/mpeg5/xevd#how-to-build) on your system
```
$ git clone https://github.com/mpeg5/xevd.git
$ cd xevd
$ mkdir build
$ cd build
$ cmake .. -DSET_PROF=BASE
$ make
$ make install
```
## Usage
### Decode
```go
import "github.com/octu0/go-xevd"
func main() {
decoder, err := xevd.CreateDefaultBaselineDecoder()
if err != nil {
panic(err)
}
defer decoder.Close()
f, err := os.Open("./testdata/src.evc")
if err != nil {
panic(err)
}
defer f.Close()
br := bufio.NewReader(f)
if err := decoder.DecodeStream(br, func(buf *xevd.DecodeImageBuffer) {
defer buf.Close()
fmt.Printf("Frame:%s Slice:%s color:%s\n", buf.NALUnit, buf.Slice, buf.ColorSpace)
// => Frame:IDR Slice:I color:YCbCr420
if err := saveImage(buf.Img); err != nil {
panic(err)
}
}); err != nil {
panic(err)
}
}
func saveImage(img image.Image) (string, error) {
out, err := os.CreateTemp("/tmp", "out*.png")
if err != nil {
return "", err
}
defer out.Close()
if err := png.Encode(out, img); err != nil {
return "", err
}
return out.Name(), nil
}
```
