# gstpl
Simple GStreamer pipeline launcher for Go.
## Example
```go
import (
"errors"
"time"
"github.com/lesomnus/gstpl"
)
func main() {
// GStreamer pipeline expression;
// for example:
// expr := `v4l2src device=/dev/video0
// ! video/x-raw,format=YUY2,width=640,height=480,framerate=30/1
// ! videoconvert
// ! x264enc speed-preset=ultrafast tune=zerolatency bitrate=500
// `
expr := "videotestsrc"
pl, err := gstpl.NewPipeline(expr)
if err != nil {
panic(err)
}
if err := pl.Start(); err != nil {
panic(err)
}
go func() {
time.Sleep(10 * time.Second)
// `Close` will unblock `Recv` with `io.EOF`.
if err := pl.Close(); err != nil {
panic(err)
}
}()
for {
sample, err := pl.Recv()
if err != nil {
if errors.is(err, io.EOF) {
break
}
panic(err)
}
// Do cool things with `sample`.
}
}
```
