Struct SceneChangeDetector 

pub struct SceneChangeDetector {
    pub threshold: u64,
    pub min_keyframe_interval: u32,
    /* private fields */
}

Scene-change detector that decides whether a new keyframe should be inserted based on a simple sum-of-absolute-differences threshold.

Fields

threshold: u64

SAD threshold above which a scene change is declared.

min_keyframe_interval: u32

Minimum number of frames between forced keyframes.

Implementations

impl SceneChangeDetector

pub fn new(threshold: u64, min_keyframe_interval: u32) -> Self

Creates a new detector.

pub fn update(&mut self, sad: u64) -> bool

Updates the detector with the SAD value for the current frame. Returns true if a scene change keyframe should be inserted.

pub fn reset(&mut self)

Forces a keyframe reset (call on IDR insertion).

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

Formats the value using the given formatter.
