Functions

func NSamples

func NSamples(d time.Duration, freq int) uint32

NSamples calculates the number of samples in media of length d with sampling frequency f. For example, NSamples(20 * time.Millisecond, 48000) will return the number of samples in a 20 millisecond segment of Opus audio recorded at 48000 samples per second.

Types

type Sample

type Sample struct {
	Data    []byte
	Samples uint32
}

A Sample contains encoded media and the number of samples in that media (see NSamples).

type Writer

type Writer interface {
	// Add the content of an RTP packet to the media
	WriteRTP(packet *rtp.Packet) error
	// Close the media
	// Note: Close implementation must be idempotent
	Close() error
}

Writer defines an interface to handle the creation of media files
