Struct RtpHeader

pub struct RtpHeader {
    pub version: u8,
    pub has_padding: bool,
    pub has_extension: bool,
    pub marker: bool,
    pub payload_type: Pt,
    pub sequence_number: u16,
    pub timestamp: u32,
    pub ssrc: Ssrc,
    pub ext_vals: ExtensionValues,
    pub header_len: usize,
}

Parsed header from an RTP packet.

Fields

version: u8

Always 2

has_padding: bool

Whether the RTP packet has padding to be an equal of 4 bytes.

has_extension: bool

RTP packet has “RTP header extensions”.

marker: bool

A marker indicates the end of a series of packets belonging together such as for a single video frame.

payload_type: Pt

Type of payload being carried. What this correlates to is sent in the SDP.

sequence_number: u16

Sequence number increasing by 1 for each RTP packet.

timestamp: u32

Timestamp in media time for the RTP packet. What the media time base is depends on the codec.

ssrc: Ssrc

Sender source identifier.

ext_vals: ExtensionValues

The extension values parsed using the mapping via SDP.

header_len: usize

Length of header.

Implementations

impl RtpHeader

pub fn create_padding_packet( buf: &mut [u8], header_len: usize, pad_len: u8, block_size: usize, ) -> usize

Write a packet consisting entirely of padding and write.

pub fn read_original_sequence_number(buf: &[u8], seq_no: &mut u16) -> usize

For RTX the original sequence number is inserted before the RTP payload.

pub fn write_original_sequence_number(buf: &mut [u8], seq_no: SeqNo) -> usize

For RTX the original sequence number is inserted before the RTP payload.

pub fn sequence_number(&self, previous: Option<SeqNo>) -> SeqNo

Sequencer number of this RTP header given the previous number.

The logic detects wrap-arounds of the 16-bit RTP sequence number.

Trait Implementations

impl Clone for RtpHeader

fn clone(&self) -> RtpHeader

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RtpHeader

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for RtpHeader

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for RtpHeader

fn eq(&self, other: &RtpHeader) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
