Hola amigos, llevo 1 mes encallado en el desarrollo de una aplicacion que haga webcam shots aleatorios cada 10 segundos, de momento solo he conseguido que reporoduzca video, y no hay manera de hacer que haga webcamshots, he probado de todo.
Aqui les dejo el codigo que tengo hasta ahora espero qe puedan ayudarme
