You can get from JSON like (if you want, you can use gjson lib)

func GetDurationFromJson() float32 {
	file := "yourfilepath"

	out, err := ffmpeg.Probe(file, []ffmpeg.KwArgs{
		{"show_entries": "format=duration"},
		{"v": "quiet"},
	}...)

	if err != nil {
		log.Fatal(err)
	}

	var JSONData map[string]interface{}

	json.Unmarshal([]byte(out), &JSONData)

	return JSONData["format"].(map[string]interface{})["duration"].(float32)
}
