Struct TimeContext 

pub struct TimeContext {
    pub time_base: TimeBase,
    pub frame_rate: u32,
    pub frame_rate_multiplier_numerator: u32,
    pub frame_rate_multiplier_denominator: u32,
    pub sub_frame_rate: u32,

}

Time context gathered from document parameters.

Defaults match TTML2 §7.2 prose defaults.

Fields

time_base: TimeBase

ttp:timeBase — default media.

frame_rate: u32

ttp:frameRate — default 30.

frame_rate_multiplier_numerator: u32

ttp:frameRateMultiplier numerator/denominator — default 1 1.

frame_rate_multiplier_denominator: u32

ttp:frameRateMultiplier denominator.

sub_frame_rate: u32

ttp:subFrameRate — default 1.

tick_rate: u32

ttp:tickRate — default derived from frame rate × sub frame rate, or 1.

drop_mode: DropMode

ttp:dropMode — default nonDrop. Only meaningful when time_base=smpte.

marker_mode: MarkerMode

ttp:markerMode — default discontinuous. Only meaningful when time_base=smpte.

clock_mode: ClockMode

ttp:clockMode — default utc. Only meaningful when time_base=clock.
