Error message

nenhuma pausa nem corte de cena encontrado; afrouxe os limiares

What it means

After running silence and scene detection, no cues were found at the configured thresholds, so chapter building is impossible. The library requires at least one detected pause or scene cut to produce chapters and suggests loosening thresholds.

Solutions

Lower the silence threshold / increase silence duration sensitivity in options
Lower opts.scene_threshold (e.g. from 0.4 to 0.3 or lower) so more cuts qualify
Provide a subtitle file so cues come from captions instead of detection
Verify the input actually contains the expected pauses/cuts

Example fix

// before
let opts = Options { scene_threshold: 0.5, ..Default::default() };
// after
let opts = Options { scene_threshold: 0.3, ..Default::default() }; // looser
run(opts, progress).await?;

Defensive patterns

Strategy: fallback

Validate before calling

// can't pre-check detection results; pre-validate thresholds are in sane range
assert!(opts.scene_threshold > 0.0 && opts.scene_threshold < 0.6);

Try / catch

match run(opts, progress).await {
    Err(e) if e.to_string().contains("nenhuma pausa nem corte") => {
        // retry once with looser thresholds or supply subtitles
    }
    other => other?,
}

Prevention

Supply a subtitle file as an alternate cue source
Start with default thresholds and adjust gradually
Test detection on a short clip before full runs

When it happens

Trigger: `run` completes detect_silence/detect_scenes and both vectors are empty — silence threshold too strict for quiet audio, or scene_threshold too high for visually static video, or both detectors disabled.

Common situations: Podcast/static-screen video with no visual cuts; audio normalized to very low noise floor failing silence threshold; user set scene_threshold very high; input too short to contain any detectable events.

Understand the failure class

Background: EmptyResultError / "no results found": when an API or scraper succeeds but returns zero rows — this error's family across 9 libraries.
