Subject: [PATCH] fix: corrige deadlock no FFmpeg por stderr redirecionado sem
 leitura
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Redirecionar stderr sem consumir o buffer causa deadlock quando FFmpeg
escreve muito (codec info, progress). Removida a redireção — stderr
vai para o processo pai (API console).
