Struct Frame 

pub struct Frame<B: Backend> {
    pub image: Image<B>,
    pub pts: Duration,
    pub duration: Duration,
    pub index: usize,
    pub is_keyframe: bool,
}

A single video frame with timing metadata.

Wraps an Image with presentation timestamp and duration information for proper video playback and editing workflows.

Fields

image: Image<B>

The image data for this frame (C, H, W tensor).

pts: Duration

Presentation timestamp — when this frame should be displayed.

duration: Duration

How long this frame should be displayed (used for variable frame rate).

index: usize

Frame index in the sequence (0-based).

is_keyframe: bool

Whether this frame is a keyframe (I-frame).

Implementations

impl<B: Backend> Frame<B>

pub fn new(image: Image<B>, pts: Duration, index: usize) -> Self

Creates a new frame with the given image and timestamp.

pub fn keyframe(image: Image<B>, pts: Duration, index: usize) -> Self

Creates a keyframe (I-frame) at the given timestamp.

pub fn with_duration(self, duration: Duration) -> Self

Sets the display duration for this frame (for variable frame rate).

pub fn width(&self) -> usize

Returns the width of the frame in pixels.

pub fn height(&self) -> usize

Returns the height of the frame in pixels.

pub fn channels(&self) -> usize

Returns the number of color channels.

pub fn shape(&self) -> [usize; 3]

Returns the frame shape as [C, H, W].

Trait Implementations
