Transloadit recomienda incluir `ffmpeg_stack: "v7"` en las Assembly Instructions de estos Robots. Sabemos muy bien lo importante que es la continuidad para nuestros clientes, por lo que las actualizaciones de la versión del stack siempre son opcionales. Por lo general, las versiones del stack reciben soporte durante muchos años antes de que comencemos a emitir advertencias de obsolescencia (por ejemplo, habíamos ofrecido soporte para `"v1.0.0"` durante 11 años antes de declararla obsoleta).
