It generates a wait on DM642 when capture 4 cameras.

Hi,

I use 4 cameras on DM642 at the same time.
It makes three output for 4 camera source by user.
The three processes are not equal period time.
For example, A is 1ms, B is 21ms, and C is 28ms.
Here, I have a problem when capture video signal.
Especially, for FVID_exchange(), it have wait time(? I don't know for
an exact terminology).
FVID_exchange(camera 1);
FVID_exchange(camera 2);
FVID_exchange(camera 3);
FVID_exchange(camera 4);
For A and C, the total waiting time is 75ms and 100ms.
I can not get 30fps because of the waiting.
How can i solve this problem?

Thanks in advance.
