ffmpeg nao iniciou

Error message

ffmpeg nao iniciou: {}

What it means

In convert_one's single-pass branch (direct libwebp_anim/GIF output), spawning ffmpeg failed: cmd.output() returned an io error wrapped as 'ffmpeg nao iniciou: {}'. The converter could not start the ffmpeg process at all.

Solutions

1. Confirm ffmpeg exists and runs at the configured path (`<ffmpeg> -version`); install or bundle it.
2. Use an absolute path to the ffmpeg binary instead of relying on PATH lookup.
3. Fix file permissions (chmod +x) and check that security software is not blocking process creation.

Example fix

// before
let ffmpeg = "ffmpeg";
// after
let ffmpeg = which::which("ffmpeg").context("ffmpeg not found on PATH; install it or set ffmpeg_path")?;

fn ensure_ffmpeg(path: &Path) -> anyhow::Result<()> {
    anyhow::ensure!(path.is_file(), "ffmpeg nao encontrado: {}", path.display());
    #[cfg(unix)]
    anyhow::ensure!(std::fs::metadata(path)?.permissions().mode() & 0o111 != 0, "ffmpeg sem permissão de execução");
    Ok(())
}

fn spawnable(p: &Path) -> bool { p.is_file() }

if let Err(e) = convert_one(...).await {
    if e.to_string().contains("nao iniciou") {
        eprintln!("instale/bundle o ffmpeg: {e}");
    } else { return Err(e); }
}

When it happens

Trigger: GIF/WebP conversion invoked when the ffmpeg binary path is wrong, the binary is missing or non-executable, or PATH resolution fails in the packaged app environment.

Common situations: ffmpeg not installed on the machine; app bundle missing the sidecar binary; wrong custom ffmpeg path in settings; execute permission stripped after copying the binary; Windows PATH not propagated to the spawned process.
