Struct SceneDetector 

pub struct SceneDetector { /* private fields */ }

Detects scene changes in a video file and returns their timestamps.

Uses FFmpeg’s select=gt(scene\,threshold) filter to identify frames where the scene changes. The threshold controls detection sensitivity: lower values detect more cuts (including subtle ones); higher values detect only hard cuts.

Examples

use ff_decode::SceneDetector;

let cuts = SceneDetector::new("video.mp4")
    .threshold(0.3)
    .run()?;

for ts in &cuts {
    println!("Scene change at {:?}", ts);
}

Implementations

impl SceneDetector

pub fn new(input: impl AsRef<Path>) -> Self

Creates a new detector for the given video file.

The default detection threshold is 0.4. Call threshold to override it.

pub fn threshold(self, t: f64) -> Self

Sets the scene-change detection threshold.

Must be in the range [0.0, 1.0]. Lower values make the detector more sensitive (more cuts reported); higher values require a larger visual difference. Passing a value outside this range causes run to return DecodeError::AnalysisFailed.

Default: 0.4.

pub fn run(self) -> Result<Vec<Duration>, DecodeError>

Runs scene-change detection and returns one Duration per detected cut.

Timestamps are sorted in ascending order and represent the PTS of the first frame of each new scene.

Errors

• DecodeError::AnalysisFailed — threshold outside [0.0, 1.0], input file not found, or an internal filter-graph error.
