Detailed Description

RTCP protocol support.

Enumeration Type Documentation

◆ ParticipantReportMode

enum roc::rtcp::ParticipantReportMode

Participant report generation mode.

Enumerator
Report_ToAddress	Reports are sent to a single static destination address, set via report_address field of ParticipantInfo struct. This mode is typically used on sender side.
Report_Back	Reports are sent back to dynamically discovered participant. In this mode, for every stream we send or receive via RTP, we remember address from which RTCP reports for that stream come. Then we send reports back to all such addresses. This mode is typically used on receiver side.

Function Documentation

◆ ntp_clamp_32()

packet::ntp_timestamp_t roc::rtcp::ntp_clamp_32	(	packet::ntp_timestamp_t	value,
		packet::ntp_timestamp_t	max_value
	)

Clamp 64-bit NTP timestamp so that it fits into middle 32-bits. Value is rounded to the new resolution and capped with given maximum. Returned value has zeros in high and low 16 bits.

◆ ntp_clamp_64()

packet::ntp_timestamp_t roc::rtcp::ntp_clamp_64	(	packet::ntp_timestamp_t	value,
		packet::ntp_timestamp_t	max_value
	)

Clamp 64-bit NTP timestamp so that it does not exceed maximum.

◆ ntp_extend()

packet::ntp_timestamp_t roc::rtcp::ntp_extend	(	packet::ntp_timestamp_t	base,
		packet::ntp_timestamp_t	value
	)

Restore full 64-bit NTP timestamp from middle 32 bits.

Parameters

value	is middle 32 bits of timestamp to be restored.
base	is full 64 bit timestamp that was recently obtained from same source. The function will combine high 16 bits of base with value. It will also detect possible wrap and apply correction if needed.

◆ print_packet()

void roc::rtcp::print_packet ( const core::Slice< uint8_t > & data )

Print RTCP compund packet.
