usb power for dm368 to capture and encode

Hi all,

          I am using dm368 board as a usb camera. I am able to do the things with this . My problem is it able to capture and encode(H264) 1080P video using usb power. Is this power is enough to do capture+encode+send through usb.

        I am using dvsdk_dm365-evm_4_00_00_22_setuplinux for doing the above things.

         Can any one please give me some clarification about dm368 power requirements for 1080P H264 encoding.

Thanks in advance,
