Is the scaler available to be applied to the raw YUV video? If so, what kind of latency is seen on scaling w/o compression? Depending on application, that could help with the raw YUV video data rate issue. -brendan ------------------------------------------------------- SF.Net email is sponsored by: Tame your development challenges with Apache's Geronimo App Server.
