simultanous DMA filling and USART Tx from memory + camera output

I have interfaced camera with STM32F4 discovery. currently I am capturing the frame and after the first capture is complete, I disable Camera capture and start sending data from memory over USART2. it sequential. and works fine.

now , I want to send data over USART2 at the same time as after each DMA memory location filled by camera DATA.

Or i want to send the first frame data from DMA0 buffer while at the same time the next frame data will be filling to DMA1 buffer.(in double buffer mode)

is it possible.  and how>? any hint....
