Struct ac_ffmpeg::time::Timestamp

pub struct Timestamp { /* fields omitted */ }

A timestamp supporting various time bases. All comparisons are done within microsecond time base.

Implementations

impl Timestamp

pub fn null() -> Self

Create a "null" timestamp (i.e. a timestamp set to the AV_NOPTS_VALUE).

pub const fn new(timestamp: i64, time_base: TimeBase) -> Self

Create a new timestamp with a given time base.

pub const fn from_secs(timestamp: i64) -> Self

Create a new timestamp with 1/1 time base.

pub const fn from_millis(timestamp: i64) -> Self

Create a new timestamp with 1/1_000 time base.

pub const fn from_micros(timestamp: i64) -> Self

Create a new timestamp with 1/1_000_000 time base.

pub const fn from_nanos(timestamp: i64) -> Self

Create a new timestamp with 1/1_000_000_000 time base.

pub fn time_base(&self) -> TimeBase

Get the time base.

pub fn timestamp(&self) -> i64

Get the raw timestamp value.

pub fn is_null(&self) -> bool

Check if this is the "null" timestamp (i.e. it is equal to the AV_NOPTS_VALUE).

pub fn with_time_base(&self, time_base: TimeBase) -> Self

Rescale the timestamp value to a given time base.

pub fn as_secs(&self) -> Option<i64>

Get the timestamp value in seconds.

pub fn as_millis(&self) -> Option<i64>

Get the timestamp value in milliseconds.

pub fn as_micros(&self) -> Option<i64>

Get the timestamp value in microseconds.

pub fn as_nanos(&self) -> Option<i64>

Get the timestamp value in nanoseconds.

pub fn as_f32(&self) -> Option<f32>

Get the timestamp value as a floating point number with 32-bit precision.

pub fn as_f64(&self) -> Option<f64>

Get the timestamp value as a floating point number with 64-bit precision.
