Could you provide a hello world please

[tmaillart]

Hello,

Thank you for this repo.

I started a simple hello world, but I don't get how you run the main loop.
Here is my faulty code

package main

import "github.com/andre-hub/go-gstreamer"

func main() {
	gst.Init(nil)
	pipeline, _ := gst.PipelineNew("player")
	filesrc, _ := gst.ElementFactoryMake("filesrc", "source-disk")
	decoder, _ := gst.ElementFactoryMake("decodebin", "decoder")
	pulsesink, _ := gst.ElementFactoryMake("pulsesink", "sink-pulse")

	filesrc.Set("location", "./audio.mp3")

	pipeline.Add(filesrc)
	pipeline.Add(decoder)
	pipeline.Add(pulsesink)

	filesrc.Link(decoder)
	decoder.Link(pulsesink)

	pipeline.SetState(gst.STATE_PLAYING)
}
