Package-Level Functions (total 13)

	 func HeaderAndPacketMarshalSize(header *Header, payload []byte) (headerSize int, packetSize int)
		HeaderAndPacketMarshalSize returns the size of the header and full packet once marshaled.
		Parts of pion code passes RTP header and payload separately, so this function
		is provided to help with that.
		
		Deprecated: this function is a temporary workaround and will be removed in pion/webrtc v5.

	 func MarshalPacketTo(buf []byte, header *Header, payload []byte) (int, error)
		MarshalPacketTo serializes the header and payload into bytes.
		Parts of pion code passes RTP header and payload separately, so this function
		is provided to help with that.
		
		Deprecated: this function is a temporary workaround and will be removed in pion/webrtc v5.

	 func NewAbsCaptureTimeExtension(captureTime time.Time) *AbsCaptureTimeExtension
		NewAbsCaptureTimeExtension makes new AbsCaptureTimeExtension from time.Time.

		NewPacketizerWithOptions returns a new instance of a Packetizer with the given options.

	 func NewRandomSequencer() Sequencer
		NewRandomSequencer returns a new sequencer starting from a random sequence
		number.

	 func PacketMarshalSize(header *Header, payload []byte) int
		PacketMarshalSize returns the size of the header and payload once marshaled.
		Parts of pion code passes RTP header and payload separately, so this function
		is provided to help with that.
		
		Deprecated: this function is a temporary workaround and will be removed in pion/webrtc v5.

	 func WithPayloadType(pt uint8) func(*packetizer)
		WithPayloadType sets the PayloadType for the Packetizer.

	 func WithSSRC(ssrc uint32) func(*packetizer)
		WithSSRC sets the SSRC for the Packetizer.

	 func WithTimestamp(timestamp uint32) func(*packetizer)
		WithTimestamp sets the initial Timestamp for the Packetizer.
