ffmpeg nao iniciou

Error message

ffmpeg nao iniciou: {}

What it means

Wraps the io::Error from spawning the ffmpeg process in restore_one's shake-detection pass (video_restore.rs:174). The library throws it when tokio's Command::output() cannot even launch ffmpeg — before any decode work happens. It is a process-spawn failure, not an ffmpeg decoding failure (that path produces the separate 'detecção de tremor' error).

Solutions

1. Install ffmpeg or ensure the binary is on PATH (verify with `ffmpeg -version` in the same environment the app runs in).
2. If ffmpeg lives outside PATH, configure the explicit binary path used to build the `ffmpeg` command variable.
3. Check exec permissions (`chmod +x $(which ffmpeg)`) and reinstall if the binary is corrupted.
4. Log the wrapped io::Error (`{e}`) — its kind (NotFound/PermissionDenied) tells which of the above applies.

Example fix

// before: relies on PATH
let out = crate::core::process::command(ffmpeg).args(["-y", ...]).output().await;
// after: resolve explicitly and fail fast with a clear message
let ffmpeg = which::which("ffmpeg").context("ffmpeg não encontrado no PATH; instale ffmpeg")?;
let out = crate::core::process::command(ffmpeg).args(["-y", ...]).output().await?;

if which::which("ffmpeg").is_err() {
    return Err(anyhow!("ffmpeg não está no PATH; instale ffmpeg antes de restaurar vídeos"));
}

match restore_one(input).await {
    Err(e) if e.to_string().contains("ffmpeg nao iniciou") => eprintln!("instale/verifique o ffmpeg: {e}"),
    Err(e) => return Err(e),
    Ok(item) => item,
}

When it happens

Trigger: Calling restore_one/run on a video whose first pass runs `ffmpeg -vf <detect> -an -f null -` and the ffmpeg binary cannot be spawned: binary absent from PATH, path misconfigured, or the OS fails exec (permissions, missing interpreter).

Common situations: ffmpeg not installed in the deployment container or CI image; PATH stripped in the Tauri GUI environment so a terminal-visible ffmpeg is not found; a broken ffmpeg shim on PATH with a bad shebang; no exec permission after a partial install.
