`x264-go` provides H.264/MPEG-4 AVC codec encoder based on [x264](https://www.videolan.org/developers/x264.html) library.
|
|
|
|
C source code is included in package. If you want to use external shared/static library (i.e. built with asm and/or OpenCL) use `-tags extlib`
|
|
|
|
### Installation
|
|
|
|
go get -u github.com/gen2brain/x264-go
|
|
|
|
### Build tags
|
|
|
|
* `extlib` - use external x264 library
|
|
* `pkgconfig` - enable pkg-config (used with extlib)
|
|
|
|
|
|
### Examples
|
|
|
|
See [screengrab](https://github.com/gen2brain/x264-go/blob/master/examples/screengrab/screengrab.go) example.
|
|
|
|
### Usage
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"bytes"
|
|
"image"
|
|
"image/color"
|
|
"image/draw"
|
|
|
|
"github.com/gen2brain/x264-go"
|
|
)
|
|
|
|
func main() {
|
|
buf := bytes.NewBuffer(make([]byte, 0))
|
|
|
|
opts := &x264.Options{
|
|
Width: 640,
|
|
Height: 480,
|
|
FrameRate: 25,
|
|
Tune: "zerolatency",
|
|
Preset: "veryfast",
|
|
Profile: "baseline",
|
|
LogLevel: x264.LogDebug,
|
|
}
|
|
|
|
enc, err := x264.NewEncoder(buf, opts)
|
|
if err != nil {
|
|
panic(err)
|
|
}
|
|
|
|
img := x264.NewYCbCr(image.Rect(0, 0, opts.Width, opts.Height))
|
|
draw.Draw(img, img.Bounds(), image.Black, image.ZP, draw.Src)
|
|
|
|
for i := 0; i < opts.Width/2; i++ {
|
|
img.Set(i, opts.Height/2, color.RGBA{255, 0, 0, 255})
|
|
|
|
err = enc.Encode(img)
|
|
if err != nil {
|
|
panic(err)
|
|
}
|
|
}
|
|
|
|
err = enc.Flush()
|
|
if err != nil {
|
|
panic(err)
|
|
}
|
|
|
|
err = enc.Close()
|
|
if err != nil {
|
|
panic(err)
|
|
}
|
|
}
|
|
```
