my BSP version L_4.1.15_1.2.0_ga

my application is multiple channel video display and I'm confused about how to handle 4 capture task by only one mxc_ipu. Someone says that IPU can handle two task at a time.Can I just use "ioctl(fd_ipu, IPU_QUEUE_TASK, &task0/1/2/3)" to convert and resize four capture buffers ? Meanwhile,could please tell me how can I know the ipu task is done ? Because I need to memcpy the buffer to v4l2_output buffer
