	}

	m, err := mf4.ReadFile(file, &mf4.ReadOptions{})
	if err != nil {
		panic(err)
	}


	fmt.Println()
	// Get channel samples
	channels := m.ListAllChannels()

	for _, channel := range channels {
		samples, err := channel.Sample()
		if err != nil {
			panic(err)
		}

		fmt.Println(samples[:10])
	}
