I've now tried using those libraries, but there seems to be an
incompatibility []float32 vs []byte.
Here's the error:
./play.go:24:29: cannot use reader (variable of type *oggvorbis.Reader) as
io.Reader value in argument to otoCtx.NewPlayer: *oggvorbis.Reader does not
implement io.Reader (wrong type for method Read)
have Read([]float32) (int, error)
want Read([]byte) (int, error)
And here's the code (main.go):
package main
import (
"log"
"os"
"time"
//"github.com/ebitengine/oto/v3"
"github.com/hajimehoshi/oto/v2"
"github.com/jfreymuth/oggvorbis"
)
func main() {
log.SetFlags(0)
file, err := os.Open(os.Args[0])
checkErr(err)
defer file.Close()
reader, err := oggvorbis.NewReader(file)
checkErr(err)
otoCtx, readyCh, err := oto.NewContext(reader.SampleRate(),
reader.Channels(), 2)
checkErr(err)
<-readyCh // wait for h/w
player := otoCtx.NewPlayer(reader)
defer player.Close()
player.Play()
for player.IsPlaying() {
time.Sleep(time.Millisecond * 10)
}
}
func checkErr(err error) {
if err != nil {
log.Fatal(err)
}
}
