Struct gstreamer_video::VideoTimeCode

pub struct VideoTimeCode { /* private fields */ }

field_count must be 0 for progressive video and 1 or 2 for interlaced.

A representation of a SMPTE time code.

hours must be positive and less than 24. Will wrap around otherwise. minutes and seconds must be positive and less than 60. frames must be less than or equal to config / config These values are NOT automatically normalized.

GLib type: Inline allocated boxed type with stack copy semantics.

Implementations

impl VideoTimeCode

pub fn as_ptr(&self) -> *mut GstVideoTimeCode

pub unsafe fn from_glib_ptr_borrow<'a>(ptr: *const GstVideoTimeCode) -> &'a Self

Borrows the underlying C value.

pub unsafe fn from_glib_ptr_borrow_mut<'a>( ptr: *mut GstVideoTimeCode, ) -> &'a mut Self

Borrows the underlying C value mutably.

impl VideoTimeCode

pub fn new_empty() -> Self

Returns

a new empty, invalid VideoTimeCode

pub fn new( fps: Fraction, latest_daily_jam: Option<&DateTime>, flags: VideoTimeCodeFlags, hours: u32, minutes: u32, seconds: u32, frames: u32, field_count: u32, ) -> Self

field_count is 0 for progressive, 1 or 2 for interlaced. latest_daiy_jam reference is stolen from caller.

fps_n

Numerator of the frame rate

fps_d

Denominator of the frame rate

latest_daily_jam

The latest daily jam of the VideoTimeCode

flags

VideoTimeCodeFlags

hours

the hours field of VideoTimeCode

minutes

the minutes field of VideoTimeCode

seconds

the seconds field of VideoTimeCode

frames

the frames field of VideoTimeCode

field_count

Interlaced video field count

Returns

a new VideoTimeCode with the given values. The values are not checked for being in a valid range. To see if your timecode actually has valid content, use is_valid().

pub fn from_date_time( fps: Fraction, dt: &DateTime, flags: VideoTimeCodeFlags, field_count: u32, ) -> Result<Self, BoolError>

The resulting config->latest_daily_jam is set to midnight, and timecode is set to the given time.

This might return a completely invalid timecode, use [from_date_time_full()][Self::from_date_time_full()] to ensure that you would get None instead in that case.

fps_n

Numerator of the frame rate

fps_d

Denominator of the frame rate

dt

glib::DateTime to convert

flags

VideoTimeCodeFlags

field_count

Interlaced video field count

Returns

the VideoTimeCode representation of dt.

pub fn is_valid(&self) -> bool

Returns

whether self is a valid timecode (supported frame rate, hours/minutes/seconds/frames not overflowing)

pub fn set_fps(&mut self, fps: Fraction)

pub fn set_flags(&mut self, flags: VideoTimeCodeFlags)

pub fn set_hours(&mut self, hours: u32)

pub fn set_minutes(&mut self, minutes: u32)

pub fn set_seconds(&mut self, seconds: u32)

pub fn set_frames(&mut self, frames: u32)

pub fn set_field_count(&mut self, field_count: u32)

impl VideoTimeCode

pub fn hours(&self) -> u32

pub fn minutes(&self) -> u32

pub fn seconds(&self) -> u32

pub fn frames(&self) -> u32

pub fn field_count(&self) -> u32

pub fn fps(&self) -> Fraction

pub fn flags(&self) -> VideoTimeCodeFlags

pub fn latest_daily_jam(&self) -> Option<DateTime>

pub fn set_latest_daily_jam(&mut self, latest_daily_jam: Option<DateTime>)
