Struct CMSampleTimingInfo 

#[repr(C)]
pub struct CMSampleTimingInfo {
    pub duration: CMTime,
    pub presentation_time_stamp: CMTime,
    pub decode_time_stamp: CMTime,
}

Sample timing information

Contains timing data for a media sample (audio or video frame).

Examples

use apple_cf::cm::{CMSampleTimingInfo, CMTime};

let timing = CMSampleTimingInfo::new();
assert!(!timing.is_valid());

let duration = CMTime::new(1, 30);
let pts = CMTime::new(100, 30);
let dts = CMTime::new(100, 30);
let timing = CMSampleTimingInfo::with_times(duration, pts, dts);
assert!(timing.is_valid());

Fields

duration: CMTime

presentation_time_stamp: CMTime

decode_time_stamp: CMTime

Implementations

impl CMSampleTimingInfo

pub const fn new() -> CMSampleTimingInfo

Create a new timing info with all times set to invalid

Examples

use apple_cf::cm::CMSampleTimingInfo;

let timing = CMSampleTimingInfo::new();
assert!(!timing.is_valid());

pub const fn with_times( duration: CMTime, presentation_time_stamp: CMTime, decode_time_stamp: CMTime, ) -> CMSampleTimingInfo

Create timing info with specific values

pub const fn is_valid(&self) -> bool

Check if all timing fields are valid Returns whether this time carries Core Media’s valid flag.

pub const fn has_valid_presentation_time(&self) -> bool

Check if presentation timestamp is valid

pub const fn has_valid_decode_time(&self) -> bool

Check if decode timestamp is valid

pub const fn has_valid_duration(&self) -> bool

Check if duration is valid

pub fn presentation_seconds(&self) -> Option<f64>

Get the presentation timestamp in seconds

pub fn decode_seconds(&self) -> Option<f64>

Get the decode timestamp in seconds

pub fn duration_seconds(&self) -> Option<f64>

Get the duration in seconds

Trait Implementations

impl Clone for CMSampleTimingInfo

fn clone(&self) -> CMSampleTimingInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CMSampleTimingInfo

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

Formats the value using the given formatter.

impl Default for CMSampleTimingInfo

fn default() -> CMSampleTimingInfo

Returns the “default value” for a type.

impl Display for CMSampleTimingInfo

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

Formats the value using the given formatter.

impl Hash for CMSampleTimingInfo

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CMSampleTimingInfo

fn eq(&self, other: &CMSampleTimingInfo) -> 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.
