Types

type Direction

type Direction string

Direction is the direction of a media stream.

const (
	DirectionSendonly Direction = "sendonly"
	DirectionRecvonly Direction = "recvonly"
	DirectionSendrecv Direction = "sendrecv"
)

standard directions.

type Media

type Media struct {
	// Media type.
	Type Type

	// Direction of the stream.
	Direction Direction

	// Control attribute.
	Control string

	// Formats contained into the media.
	Formats []format.Format
}

Media is a media stream. It contains one or more formats.

func (Media) FindFormat

func (m Media) FindFormat(forma interface{}) bool

FindFormat finds a certain format among all the formats in the media.

func (Media) Marshal

func (m Media) Marshal() *psdp.MediaDescription

Marshal encodes the media in SDP format.

func (Media) URL

func (m Media) URL(contentBase *url.URL) (*url.URL, error)

URL returns the absolute URL of the media.

type Medias

type Medias []*Media

Medias is a list of media streams.

func (Medias) FindFormat

func (ms Medias) FindFormat(forma interface{}) *Media

FindFormat finds a certain format among all the formats in all the medias. If the format is found, it is inserted into forma, and its media is returned.

func (Medias) Marshal

func (ms Medias) Marshal(multicast bool) *sdp.SessionDescription

Marshal encodes the medias in SDP format.

func (Medias) SetControls

func (ms Medias) SetControls()

SetControls sets the control attribute of all medias in the list.

func (*Medias) Unmarshal

func (ms *Medias) Unmarshal(mds []*psdp.MediaDescription) error

Unmarshal decodes medias from the SDP format.

type Type

type Type string

Type is the type of a media stream.

const (
	TypeVideo       Type = "video"
	TypeAudio       Type = "audio"
	TypeApplication Type = "application"
)

standard media stream types.
