Subject: BT848 driver code

I think that data in BT848's memory is transferred to graphic card memory

to show the captured data at monitor.

Am i right?

If right, what variable is pointed to graphic card memory in device driver
code?

(I think in /drivers/media/video/bttv-driver.c)

Or is memory in graphic card managed by more complex scheme as page?


Please answer, thanks.

Hi,

You may want to give a look at the Video4Linux2 specs:
