Estuve probando antes de escribir y no hubo caso, no pude hacerlo
andar, intenté todas las combinaciones posibles y no arrancó. Me
suscribí a la lista de correo de cheese a ver si encuentro las
opciones para correrlo desde la línea de comandos (o aunque sea para
poder indicar que se abra y comienze a grabar).
Muchas gracias Lucas por tu tiempo y preocupación, y gracias a todos
en general. Les aviso si consigo hacerlo andar.
