Hi all

I use dvrrdk3.0 for our project.

I want to caputure image from VIN0 PORTA and then save a yuv file to A8 host , so I create a very simple

data chain as below.

Capture (YUV422I) --> IPC Frames Out1 (VPSS M3) --> IPC Frames IN (A8)

Does the chain can work?

Yes such a chain will work. But it will result in a lot of capture frame drop as writing video frame to a file will take much longer than capture frame duration.
