Detailed Description

An RTP data transport.

Function Documentation

◆ datatype99()

datatype99	(	SmolRTSP_RtpTimestamp	,
		(SmolRTSP_RtpTimestamp_Raw, uint32_t)	,
		(SmolRTSP_RtpTimestamp_SysClockUs, uint64_t)
	)

An RTP timestamp.

Variants

Raw – The value to be assigned to SmolRTSP_RtpHeader.timestamp without further conversion.
SysClockUs – The timestamp value in microseconds derived from a system clock (e.g., clock_gettime). It should be used when a raw timestamp cannot be computed, as typically occurs with real-time video.

See Datatype99 for the macro usage.

◆ declImplExtern99()

declImplExtern99	(	SmolRTSP_Droppable	,
		SmolRTSP_RtpTransport
	)

Implements SmolRTSP_Droppable_IFACE for SmolRTSP_RtpTransport.

See Interface99 for the macro usage.

◆ SmolRTSP_RtpTransport_new()

SmolRTSP_RtpTransport* SmolRTSP_RtpTransport_new	(	SmolRTSP_Transport	t,
		uint8_t	payload_ty,
		uint32_t	clock_rate
	)

Creates a new RTP transport from the underlying level-4 protocol t.

Parameters

[in]	t	The level-4 protocol (such as TCP or UDP).
[in]	payload_ty	The RTP payload type. The list of payload types is available here: https://en.wikipedia.org/wiki/RTP_payload_formats.
[in]	clock_rate	The RTP clock rate of `payload_ty` (HZ).

Precondition: t.self && t.vptr; The rand PRNG must be set up via srand.

◆ SmolRTSP_RtpTransport_send_packet()

int SmolRTSP_RtpTransport_send_packet	(	SmolRTSP_RtpTransport *	self,
		SmolRTSP_RtpTimestamp	ts,
		bool	marker,
		U8Slice99	payload_header,
		U8Slice99	payload
	)

Sends an RTP packet.
