I want to calculate the current datarate, while camogm is recording I
can do that as camogm supplies recording duration and filesize of the

What would be the best way to calculate datarate without camogm?
Is there are a way to get the filesize of a single frame

If you don't mind making the FOV narrower you can make the window of
interest (WOI) smaller and get higher fps.
You mentioned garbage output, what exactly are you trying to change
and what are the results you get?

For this you would not need any PCB or circuit at all to inject the

Do you think that http://en.wikipedia.org/wiki/CFast#CFast CFast Cards

http://www.amazon.de/exec/obidos/ASIN/b003r4ifmg/geizhals1-21/ref=nosim?m=A3JWKAKR8XB7XF

To my understanding the card itself acts like a drive and needs

not too easy - otherwise Axis people would do it themselves. But if anybody
with the driver development skills would volunteer - we would definitely
