Struct TimecodeMeta 

pub struct TimecodeMeta {
    pub hours: u8,
    pub minutes: u8,
    pub seconds: u8,
    pub frames: u8,
    pub drop_frame: bool,
    pub framerate_q16: Option<u32>,
}

The SMPTE ST 12M timecode a coded picture carries (H.264 pic_timing / H.265 time_code SEI, or a container timecode track): where this frame sits on the source’s own clock, which is what an edit list, a broadcast log, or a burnt-in overlay refers to.

Fields

hours: u8

minutes: u8

seconds: u8

frames: u8

drop_frame: bool

NTSC drop-frame counting (the 29.97 / 59.94 fps count that skips two frame numbers a minute). Rendered with a ; before the frame count.

framerate_q16: Option<u32>

Frames per second the count runs at, Q16 fixed point like Rate::Fixed. None when the source declared none, so a consumer cannot convert the count to a duration.

Trait Implementations

impl Clone for TimecodeMeta

fn clone(&self) -> TimecodeMeta

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TimecodeMeta

impl Debug for TimecodeMeta

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

Formats the value using the given formatter.

impl Default for TimecodeMeta

fn default() -> TimecodeMeta

Returns the “default value” for a type.

impl Eq for TimecodeMeta

impl FrameMeta for TimecodeMeta

fn propagate(&self, _transform: Transform) -> Propagation

A position on the source’s clock: unchanged by any pixel work, and it is exactly what a re-encode should carry into the new bitstream.

fn as_any(&self) -> &dyn Any

fn as_any_mut(&mut self) -> &mut dyn Any

fn clone_box(&self) -> Box<dyn FrameMeta>

A boxed deep copy of this meta, the GstMeta copy_func analog. Backs the copy-on-write of a shared meta when a tee branch mutates it (see FrameMetaSet::get_mut); each FrameMeta impl is its own concrete type, so the duplication can only be expressed on the trait.

impl PartialEq for TimecodeMeta

fn eq(&self, other: &TimecodeMeta) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
