G'day Gurcharan and Jeremy In regards to pixel size, I have sent my laptop screen 1280 x 800 in which works very well. I have also tried sending my main AG nodes screen 4128 x 768 in which seems to work. It did appear a little slow, but I suspect this is because I was VNC'ing into the machine and the machine is quite old.
In regards to frame rates, it appears the version I am using is only capable of 10 frames a second. As a hint, if you bump up the quality and bandwidth, it produces a pretty good video stream. Thank for your emails, Jason. -----Original Message----- From: Jeremy Mann [mailto:jeremym...@gmail.com] Sent: Monday, 29 October 2007 11:52 PM To: gurcharan khanna Cc: ag-tech Subject: Re: [AG-TECH] VPCScreen Capture I too would be interested in streaming the entire Desktop. We're coming into issues with VNC that I can't seem to solve when a lot of people connect.
