Struct VideoInput 

pub struct VideoInput {
    pub frames: Vec<DynamicImage>,
    pub fps: f64,
    pub total_num_frames: usize,
    pub sampled_indices: Vec<usize>,
}

Decoded video input: a sequence of frames with metadata for timestamp generation.

Create from pre-decoded frames with VideoInput::from_frames, or use the server-core parse_video_url helper to decode from a video file (requires FFmpeg for non-GIF formats).

Fields

frames: Vec<DynamicImage>

Decoded video frames (RGB images).

fps: f64

Frames per second of the original video. Used to compute per-frame timestamps for the prompt (e.g. "00:05"). Defaults to 24.0.

total_num_frames: usize

Total number of frames in the original video before sampling.

sampled_indices: Vec<usize>

Indices of the frames that were sampled from the original video. Length must equal frames.len().

Implementations

impl VideoInput

pub fn from_frames( frames: Vec<DynamicImage>, fps: f64, sampled_indices: Option<Vec<usize>>, ) -> Self

Create a VideoInput from pre-decoded frames.

fps is the original video frame rate (used for timestamp generation). If the frames were not sampled (i.e. all frames are provided), pass None for sampled_indices and they will default to 0..frames.len().

pub fn timestamps_secs(&self) -> Vec<f64>

Compute per-frame timestamps in seconds.

pub fn timestamp_strings(&self) -> Vec<String>

Format timestamps as "mm:ss" strings.

pub fn frame_hashes(&self) -> Vec<u64>

Compute a content hash for each frame (for prefix caching).

pub fn video_hash(&self) -> u64

Compute a single hash representing the entire video (for prefix caching).

Trait Implementations

impl Clone for VideoInput

fn clone(&self) -> VideoInput

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VideoInput

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

Formats the value using the given formatter.

impl PartialEq for VideoInput

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
