Bom pessoal, meu primeiro tópico no GUJ portanto desconsiderem qualquer erro de post.
Estou querendo fazer um programa (cliente), onde o servidor está conectado à uma WebCam
e o cliente visualiza as imagens, para a comunicacao via web uso o Java.net, e para a webcam encontrei dois métodos,
um com JMF e outro com Direct Show, ambos Funcionando.(mais abaixo seguem os códigos)
agora, … como fazer o envio do video, como o java.net envia?? (stream, buffer ???)
Código WebCam DSj :

Creio que preciso criar uma classe que recebe a webcam a ser exibida, e me retorna só o video (mas como???)
Muito Obrigado
