hi
i am working on 8168+pcie+6678,i want to use 8168 capture or read video frames,then send to 6678 by pcie interface,6678 process the video frames with video process alg,then 6678 send the processed video frames to 8168.
i want to ask should i use the mcfw in the dvr or use the video examples in the ezsdk?which is better for develop the 8168+pcie+6678 video process system?if i use the mcfw in the dvr,i feel that it is diffcult to modify and add codes related with pcie to 6678.if use the video examples in the ezsdk,i feel that i can use the examples to add codes related with pcie to 6678,it clear.
and a important thing is that 8168 DMA transmit to 6678 by pcie，it use physical address，how to ensure alloced physical address is continue and have a size of 1080p video frame，then ensure the processed video display fluencily。
do you have some experience or advices？
thanks。best regards
