Struct mpeg2ts_reader::packet::ClockRef

pub struct ClockRef { /* fields omitted */ }

A Clock Reference is used to represent the values of PCR and ESCR fields within the transport stream data.

A Clock Reference includes a 33-bit, 90kHz base component, together with another 9-bit, high-resolution extension component.

Together these can be viewed as a 42-bit, 27MHz quantity (e.g. let full_value = pcr as u64). Since the clock reference is limited to 33-bits, at a rate of 90kHz a continuously increasing clock value will wrap-around approximately every 26.5 hours.

Implementations

impl ClockRef

pub fn from_slice(data: &[u8]) -> ClockRef

Panics if data is shorter than 5 bytes

pub fn from_parts(base: u64, extension: u16) -> ClockRef

Panics if the base is greater than 2^33-1 or the extension is greater than 2^9-1

pub fn base(&self) -> u64

get the 33-bit, 90kHz ‘base’ component of the timestamp

pub fn extension(&self) -> u16

get the 9-bit ‘extension’ component of the timestamp, measured in 300ths of the 90kHz base clockrate (i.e. 27MHz)

Trait Implementations

impl Clone for ClockRef

fn clone(&self) -> ClockRef

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for ClockRef
