Hi,
I am new to Arduino but have some experience with electronics. I am trying to find a way to control streaming video (input) VGA, RGB, and process it to output on a  large array of RGB leds. Is this possible with Arduino. Any ideas?

If you're saying "I want to take some video stream and have a visual representation of that stream appear on a matrix of LEDs, in a manner similar to a monitor", then the answer is no.

Not without external hardware to digitise the video for you.

O.k.
Thanks for the reply any ideas or places you could point me to please.

Hi,
Could you tell me what kind of format the ideal digitized video would have to be in, for example could it be Mpeg 4 ?

For a microcontroller (without a DSP), that would probably be one of the worst formats, because decoding it is both memory and processor intensive.

Quite simply no it is not possible, you could do it but I can't see an Arduino playing any useful role in the operation.

Even simulating an VGA signal is difficult see:- http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1228264461

..beyond, maybe counting line and frame interrupts from the sync splitter.
Now, that's given me an idea...    :D
