legenda não encontrada

Error message

legenda não encontrada: {}

What it means

run() validates that the subtitle/danmaku file (opts.subtitle) exists as a regular file after trimming. If missing, it throws 'legenda não encontrada: <path>'. The subtitle is the second required input for burning danmaku comments into the video.

Solutions

1. Verify the subtitle file exists with std::path::Path::is_file() before calling run
2. Run the danmaku export stage first and thread its actual output path into BurnOptions.subtitle
3. Handle the no-comments case explicitly (empty danmaku) instead of passing a missing file path

Example fix

// before
burn::run(&BurnOptions { subtitle: "danmaku.ass".into(), ..opts })
// after
let sub = "danmaku.ass";
anyhow::ensure!(
    std::path::Path::new(sub).is_file(),
    "legenda ausente: {} — exporte os comentários antes de gravar",
    sub
);
burn::run(&BurnOptions { subtitle: sub.into(), ..opts })

fn ensure_subtitle(path: &str) -> Result<(), String> {
    if std::path::Path::new(path.trim()).is_file() { Ok(()) }
    else { Err(format!("legenda não encontrada: {}", path)) }
}

fn has_subtitle(opts: &BurnOptions) -> bool {
    !opts.subtitle.trim().is_empty() && std::path::Path::new(opts.subtitle.trim()).is_file()
}

match burn::run(&opts, &progress).await {
    Err(e) if e.to_string().starts_with("legenda não encontrada") => skip_burn_or_reexport_danmaku(&opts),
    Err(e) => propagate(e)?,
    Ok(res) => use_result(res),
}

When it happens

Trigger: Calling burn::run with BurnOptions.subtitle pointing to a non-existent, empty-string, or deleted subtitle file (e.g. the danmaku export step of export.rs never ran or wrote to a different path).

Common situations: Danmaku export was skipped or failed; subtitle written to a temp dir that was cleaned; mismatch between export output path and burn input path; video has no comments so no subtitle was produced.

Understand the failure class

Background: "File not found" and ENOENT errors: why libraries can't find a file that should exist — this error's family across 50 libraries.
