Go bindings for [divideon/xvc](https://github.com/divideon/xvc)
Available for encode/decode of xvc video codec.
## Requirements
requires xvc [install](https://github.com/divideon/xvc#linux-build-steps) on your system
```
$ git clone https://github.com/divideon/xvc.git
$ cd xvc
$ mkdir build
$ cd build
$ cmake ..
$ make
$ make install
```
## Usage
### Encode
```go
import "github.com/octu0/go-xvc"
func encode(out io.Writer) {
encoder, err := xvc.CreateEncoder(
xvc.EncoderParameterWidth(width),
xvc.EncoderParameterHeight(height),
xvc.EncoderParameterFramerate(30.0),
)
if err != nil {
panic(err)
}
defer xvc.DestroyEncoder(encoder)
var userData int64
nals, err := encoder.Encode(
img.Y, // y plane
img.Cb, // u plane
img.Cr, // v plane
img.YStride, // y stride
img.CStride, // u stride
img.CStride, // v stride
userData, // int64 user_data
)
if err != nil {
panic(err)
}
if remainingNals, ok := encoder.Flush(); ok {
nals = append(nals, remainingNals...)
}
for _, nal := range nals {
defer nal.Close()
if _, err := out.Write(nal.Bytes()); err != nil {
panic(err)
}
}
}
```
### Decode
```go
import "github.com/octu0/go-xvc"
func decode(in io.Reader) {
decoder, err := xvc.CreateDecoder(
xvc.DecoderParameterMaxFramerate(30.0),
)
if err != nil {
panic(err)
}
defer xvc.DestroyEncoder(decoder)
data, err := io.ReadAll(in)
if err != nil {
panic(err)
}
if err := decoder.Decode(data); err != nil {
panic(err)
}
if decoder.Flush(); != true {
panic("failed to flush")
}
for {
pic, err := decoder.DecodedPicture()
if err != nil {
break
}
defer pic.Close()
fmt.Printf(
"type=%s color_matrix=%d img=%T\n",
pic.Type(), pic.ColorMatrix(), pic.Image(),
) // => type=intra_access_picture color_matrix=3 img=*image.YCbCr
}
}
```
