ffmpeg nao iniciou

Error message

ffmpeg nao iniciou: {}

What it means

to_webm() runs ffmpeg to transcode a Switch album clip; if ffmpeg fails to start at all (spawn/exec error, surfaced via .output()), the OS error is wrapped in this message. A non-zero ffmpeg exit is handled separately with stderr.

Solutions

1. Install ffmpeg and ensure `ffmpeg -version` works in a terminal
2. Add ffmpeg's directory to PATH (or to wherever crate::core::process::command resolves binaries)
3. If installed, check the OS error: 'Permission denied'/'Access denied' means unblock/chmod the binary

// verify ffmpeg availability before transcoding
let ok = tokio::process::Command::new("ffmpeg")
    .arg("-version").output().await.map(|o| o.status.success()).unwrap_or(false);
if !ok { return Err(anyhow!("ffmpeg nao disponivel")); }

match to_webm(&input, &dir).await {
    Ok(out) => out,
    Err(e) if e.to_string().contains("ffmpeg nao iniciou") => {
        // keep original file or prompt user to install ffmpeg
        anyhow::bail!("instale o ffmpeg para converter videos: {e}")
    }
    other => other,
}

When it happens

Trigger: The ffmpeg .output() call returns Err: ffmpeg not on PATH, permission denied on the binary, or process could not be created.

Common situations: ffmpeg not installed on the user's machine; ffmpeg present but blocked by antivirus; broken PATH in the app's environment (GUI apps often have a minimal PATH).
